Most articles on business sale taxes are written for the moment after the LOI is signed. By that point, 70% of the levers that move tax outcomes are already locked. Your entity structure is what it is. Your state of residency is what it is. Your QSBS holding period either qualifies or it doesn’t. The asset/stock structure of the deal has been broadly framed in the LOI itself.

This checklist is written for the 12 months before that moment. It assumes you’re between “I’m thinking about selling” and “I’m signing an LOI.” That window — usually 6-24 months long — is when the structural decisions get made that determine whether your $5M sale nets you $3.4M after tax or $4.2M after tax.

On a typical lower middle market deal, that gap is $250K-$1M of unforced error.

Nothing in this article is a substitute for a CPA and a tax attorney. Every situation differs. Federal rules change. State rules vary widely. The IRS challenges aggressive planning. What this article does is give you the structural map — the things to ask your CPA about, the moves to consider 12-24 months ahead, the negotiation points to fight for during the LOI.

One framing note before the checklist. Tax planning is not the same as tax avoidance. The goal isn’t to find loopholes. It’s to make sure the structure of the sale matches the structure the IRS gives favorable treatment to — QSBS, ESOPs, installment sales, qualified opportunity zones, charitable remainder trusts, gifting strategies. Each is a legitimate code section with rules. The checklist below is about using them on purpose instead of by accident.

“The single most expensive mistake owners make isn’t picking the wrong buyer or accepting the wrong multiple. It’s starting tax planning the week the LOI gets signed instead of 18 months earlier — and paying a sell-side broker $300K-$1M to find buyers a buy-side partner already knows.”

TL;DR — the 90-second brief

  • Tax planning that begins after the LOI is signed is too late. The most valuable structural moves — entity conversions, QSBS qualification, state residency, gifting strategies — require 12-60 months of lead time. Owners who skip the runway routinely overpay 15-25% in unnecessary tax.
  • Entity structure is the single biggest lever. A C-corp with QSBS-qualified stock can produce up to $10M+ of fully tax-free gain per shareholder under Section 1202. An asset sale from an S-corp can cost 5-10 percentage points more than a stock sale of the same business.
  • State of residency at closing matters more than where the business operates. California taxes capital gains at 13.3%. Texas, Florida, Tennessee, Wyoming, and others tax them at 0%. Establishing residency before the sale (with real domicile facts, not just a mailing address) is a 12-24 month project, not a closing-day check-box.
  • Allocation of purchase price between asset classes drives ordinary vs. capital tax treatment. A poorly negotiated allocation can shift millions of dollars of value from capital gains (20%) to ordinary income (37%+). The negotiation happens during the LOI — not at closing — so the planning has to be done first.
  • Most sellers leave 5-15% of net proceeds on the table by approaching tax planning reactively. On a $5M sale, that’s $250K-$750K. On a $20M sale, $1M-$3M. The 12-month checklist below is the structural work the best advisors run with their clients — the work that happens long before any buyer is at the table or any broker is paid $300K-$1M to find one we already know.
  • The 12-month pre-sale tax window is when the most expensive mistakes happen — or get prevented. We’re a buy-side partner working directly with 76+ buyers across search funders, family offices, lower middle-market PE, and strategic consolidators. We coordinate with your tax counsel so the structure your CPA designed survives buyer diligence. Buyers pay us, not you.

Key Takeaways

  • Start tax planning 12-24 months before you intend to sell, not at LOI. The biggest levers require runway.
  • Entity structure (C-corp, S-corp, LLC, partnership) drives tax outcomes more than any other variable.
  • QSBS Section 1202 can exclude up to $10M+ of gain per shareholder if the holding period and entity rules are met.
  • State residency at closing is a 12-24 month project. Establish real domicile facts, not just a mailing address.
  • Asset vs. stock sale structure shifts millions in tax burden. The negotiation happens at LOI, not closing.
  • Installment sales, ESOPs, charitable remainder trusts, and qualified opportunity zones are legitimate tools — if you plan ahead.

Why most owners overpay 15-25% in unnecessary tax at sale

The biggest mistake owners make in business sales isn’t picking the wrong buyer or accepting a low multiple. It’s starting tax planning the week the LOI gets signed instead of 18 months earlier. By the time the LOI is on the table, your entity is fixed, your state of residency is fixed, your QSBS clock either ran or didn’t, and the asset/stock framing of the deal is broadly set. The structural levers are gone.

On a $5M business sale, the difference between proactive and reactive tax planning is typically $250K-$750K of net proceeds. On a $10M sale, $500K-$1.5M. On a $20M sale, $1M-$3M. These are not theoretical numbers — they’re the gap between owners who took the 12-month checklist seriously and owners who didn’t.

Three categories of tax leakage account for almost all of the avoidable cost. First, entity structure mismatched to the sale type (a C-corp double-taxed on an asset sale; an S-corp missing built-in gains relief). Second, state residency — selling as a California resident when you could have legitimately been a Florida or Texas resident. Third, asset/stock allocation — agreeing to depreciation recapture and goodwill splits in the LOI that push value into ordinary income brackets.

The checklist below is organized by month-to-LOI. T-12 through T-9: structural work (entity conversions, QSBS planning, residency moves). T-9 through T-6: documentation and validation (sell-side QoE, attorney review, CPA modeling). T-6 through T-3: negotiation prep (allocation strategy, earnout taxation, rollover equity). T-3 through close: execution (LOI tax language, closing-day structure, post-close compliance).

T-12 to T-9 months: structural moves that need runway

The earliest months of pre-sale planning are when the biggest structural decisions get made. Anything that requires a holding period (QSBS, long-term capital gains qualification on certain assets), a domicile change (state residency), or an entity conversion (C-corp to S-corp, sole prop to LLC) needs to happen here. Wait too long and these levers disappear.

Entity structure review. C-corp, S-corp, LLC, partnership, and sole prop each carry different consequences at sale. A C-corp asset sale is double-taxed: corporate gain at 21% federal plus shareholder dividend at 20-23.8%. A C-corp stock sale avoids the double tax but only if the buyer agrees (and most strategic buyers prefer asset deals). An S-corp asset sale generally has single-level taxation at the shareholder level. LLCs and partnerships are flexible but allocations matter.

QSBS (Section 1202) qualification. If your business is a domestic C-corp with under $50M in gross assets at issuance, in a qualified trade or business, and you’ve held the stock for at least 5 years, you may exclude up to the greater of $10M or 10x your basis from federal capital gains entirely. On a $10M sale, that’s up to $2.38M of federal tax saved per qualifying shareholder. The 5-year clock means QSBS planning has to start years in advance.

State residency planning. California taxes capital gains at 13.3%. New York at 10.9%. New Jersey at 10.75%. Florida, Texas, Tennessee, Wyoming, South Dakota, Nevada, and others at 0%. On a $5M gain, the difference between selling as a California resident and a Florida resident is $665K of state tax. Establishing real residency — not just a mailing address — takes 12-24 months and requires actual domicile facts: physical residence, voter registration, drivers license, doctors, family ties, days-in-state records.

Family gifting and trust planning. If part of your equity will pass to family or charity, gifting it before the sale lets you transfer pre-appreciation value. Annual exclusion gifts ($18K per recipient in 2026), GRATs, IDGTs, and dynasty trusts can move significant value out of your taxable estate at low or zero gift-tax cost. The valuation has to support the gift and the transfer has to happen well before the LOI — otherwise the IRS will argue the transferred value reflects deal expectations rather than independent worth.

T-9 to T-6 months: documentation and CPA validation

By month 9 pre-LOI, the structural decisions are made (or running on their clocks). The next phase is making sure the documentation supports them. The IRS challenges aggressive planning, and buyers’ QoE teams will rip apart anything that looks like late-game tax engineering. The defensive work happens here.

Sell-side Quality of Earnings (QoE). A sell-side QoE costs $25-75K and pre-validates your reported EBITDA against buyer-grade scrutiny. From a tax perspective, it also surfaces the add-backs and one-time items that will become negotiating points: owner compensation normalization, family-on-payroll questions, personal-use assets, related-party rent. Cleaning these up pre-market is much cheaper than re-trading mid-deal.

Basis reconstruction. Your gain is sale price minus basis. For owners who’ve operated a business for 10-30 years, basis can be poorly documented — especially across capital contributions, retained earnings, S-corp distributions, and partnership allocations. A clean basis schedule prepared 6-9 months before the sale prevents the buyer’s attorney from disputing your basis at closing and saves negotiation friction.

CPA tax modeling. Run scenarios with your CPA: asset sale vs. stock sale, different allocation splits, with and without earnout, with and without rollover equity, with and without seller note. Each scenario produces a different after-tax outcome. The buyer’s offer will frame the structure — but knowing your after-tax sensitivity in advance lets you negotiate the LOI on the right axes.

Estate and gift tax review. If gifting hasn’t been done and won’t happen pre-LOI, model the estate impact. The federal estate exemption ($13.61M per individual / $27.22M per couple in 2026, dropping in 2026 unless extended) will determine whether the proceeds need to be moved into trust structures. State estate taxes (12 states + DC have them) add additional planning complexity.

Asset Sale vs Stock Sale: Who Wins, Who Loses Asset Sale vs Stock Sale: The Tax Trade-Off Asset Sale Buyer purchases the assets, not the entity Buyer wins Step-up basis, depreciate No legacy liabilities Seller pays more tax Ordinary income on equipment Depreciation recapture Seller after-tax ($5M deal): ~$3.40M After ~32% blended federal + state When it happens: • Most small-business deals (LLC, S-corp) • Buyer wants to avoid hidden liabilities • Default in 70%+ of sub-$10M sales Seller leverage to push for stock sale: weak Stock Sale Buyer purchases the entity itself (shares) Seller wins Long-term capital gains only QSBS may apply (Sec 1202) Buyer takes risk No step-up basis Inherits all liabilities Seller after-tax ($5M deal): ~$3.95M After ~21% blended LTCG + state When it happens: • C-corp targets (most strategic acquisitions) • License/permit transfer matters • ~25% of sub-$10M deals Seller leverage in C-corp: ask for purchase price gross-up ~$550K after-tax difference on the same $5M deal — structure decision matters as much as price
Illustrative tax outcomes. Actual rates depend on entity type, state, holding period, QSBS qualification, and asset mix. Always model with your CPA before signing.

T-6 to T-3 months: negotiation prep for the LOI

The LOI is where most of the deal’s tax structure gets locked. By the time you’re negotiating the LOI, your entity is fixed, your residency is fixed, your QSBS clock has run or hasn’t. What remains negotiable is the structure of the deal itself: asset vs. stock, allocation across asset classes, earnout terms, rollover equity, seller note, escrow holdback. Each has tax consequences.

Asset sale vs. stock sale negotiation. Buyers prefer asset sales because they get a stepped-up basis (and depreciation deductions on the new basis). Sellers prefer stock sales because they get capital gains treatment on the entire transaction. The tradeoff: buyers will typically pay 5-15% more for a stock sale (or pay you a tax gross-up). Don’t accept asset-sale structure without modeling the after-tax impact and asking for the gross-up.

Allocation of purchase price (asset sale). If the deal is structured as an asset sale, the IRS Form 8594 allocation determines tax treatment of each dollar. Inventory and accounts receivable are ordinary income. Equipment is depreciation recapture (ordinary up to original basis, capital above). Goodwill is capital gain. Non-compete payments are ordinary. Negotiating the allocation toward goodwill (capital, 20%) and away from non-compete (ordinary, 37%+) can save hundreds of thousands.

Earnout taxation. Earnouts are taxed under the installment sale rules generally — gain is recognized as payments are received. But the installment method has limits, anti-abuse provisions, and interest-imputation rules. Earnouts tied to ongoing employment can be reclassified as compensation (ordinary income, not capital). Structure earnouts to maintain capital treatment: tie them to enterprise-level metrics, not personal performance.

Rollover equity. Rolling 10-30% of your equity into the buyer’s entity can defer tax on the rolled portion (treated as a tax-deferred reorganization if structured properly). Typical with PE buyers. The rollover gives you a second bite at growth and defers tax until you exit the new entity. The structuring rules are technical (Section 351, Section 368) and the buyer’s structure has to accommodate.

T-3 months to close: execution and LOI tax language

Once the LOI is signed, the tax structure is largely locked. The remaining work is making sure the LOI language and the final purchase agreement reflect what was negotiated, and that closing-day mechanics don’t introduce surprises.

LOI tax language to fight for. Tax representations and warranties (the seller’s representations about prior tax compliance) should be scoped reasonably — usually 3-7 years of look-back, capped at a percentage of purchase price. Indemnification for pre-closing tax liabilities should be capped at the escrow holdback (typically 5-10% of price held for 12-24 months). Tax cooperation provisions should specify who handles tax filings for the closing year and who pays for tax-related professional services post-close.

Closing-day mechanics. Make sure the closing date doesn’t accidentally trigger a short tax year that increases your effective rate. Make sure the wire instructions and entity receiving proceeds match your tax planning (e.g., proceeds should go to the entity or trust that owns the equity, not to you personally if you’ve structured a CRT or installment note). Make sure withholding obligations (FIRPTA if foreign buyer, state withholding rules) are handled at closing rather than chased afterward.

Post-close compliance. File the final corporate or partnership return on time. File Form 8594 (asset acquisition statement) consistent with the buyer’s filing — mismatched filings invite IRS scrutiny. File any state notification requirements (some states require notice of business cessation). Maintain records for at least 7 years post-close in case of audit.

QSBS Section 1202: the most powerful tool most owners miss

Section 1202 of the Internal Revenue Code allows shareholders of qualified small business stock (QSBS) to exclude up to $10M (or 10x basis, whichever is greater) of gain from federal capital gains tax entirely. On a $10M sale of qualifying stock, that’s up to $2.38M of federal tax saved per shareholder. For a husband-and-wife pair holding stock jointly through separate trusts, the exclusion can be doubled or stacked across family members.

Qualifying for QSBS requires meeting all of the following: the stock must be issued by a domestic C-corp, the corporation must have under $50M in gross assets at the time of issuance and immediately after, the corporation must be in a qualified trade or business (excludes most professional services, financial services, hospitality, farming), the shareholder must hold the stock for at least 5 years, and the shareholder must have acquired the stock at original issuance (not from a secondary buyer).

Common reasons owners don’t qualify: the business is an S-corp or LLC (not a C-corp). The shareholder bought into an existing business rather than founding it. The business is in an excluded sector (most professional services, hospitality, banking, insurance, restaurants). The 5-year clock hasn’t run. Each of these is fixable with enough lead time — converting an LLC to a C-corp can start a new QSBS clock if structured carefully.

The 5-year holding period is the biggest planning constraint. If you’re currently 3 years into holding QSBS-qualified stock and considering a sale, waiting 2 more years before going to market may save you the federal tax on up to $10M of gain. On a typical LMM deal, that math justifies 24 months of patience. If the holding period is partially complete, a Section 1045 rollover into qualifying replacement QSBS can sometimes preserve the clock.

State residency: the second-biggest lever, and the most overlooked

State capital gains taxes range from 0% to 13.3%. California (13.3%), Hawaii (11%), New York (10.9%), New Jersey (10.75%), Oregon (9.9%), and Minnesota (9.85%) are the highest. Texas, Florida, Tennessee, Wyoming, South Dakota, Nevada, Washington (no individual income tax), Alaska, and New Hampshire (limited) have no state-level capital gains. On a $5M gain, the difference between selling as a California resident and a Florida resident is $665K.

Establishing residency is not a closing-day check-box. States like California, New York, and New Jersey aggressively challenge residency changes that look like tax-driven moves. They examine domicile facts: physical residence, voter registration, drivers license, family ties, doctors, dentists, religious institutions, days-in-state records, where pets live, where personal items are stored, where personal email and phone bills are sent. Establishing real residency typically takes 12-24 months of consistent facts.

What ‘real residency’ looks like. You buy or lease a primary residence in the new state. You spend more than 183 days per year there. You change your drivers license and vehicle registration. You vote there. You file federal returns from that address. Your spouse and minor children primarily live there. You move your primary doctor, dentist, and lawyer. Your bank accounts, brokerage accounts, and credit card statements go there. You don’t maintain a primary residence in the old state.

What doesn’t work. Renting a small apartment in Florida while keeping your California house and spending 11 months a year there. Changing your mailing address but not actually moving. Claiming residency in Texas while your kids attend school in California. States have audit teams whose entire job is challenging these claims. Failed residency claims trigger back taxes plus penalties and interest — sometimes wiping out the projected savings entirely.

Trust-based residency planning. An alternative to personal residency change is to transfer equity to a trust domiciled in a no-tax state (Nevada, South Dakota, Wyoming, Delaware) before the sale. The gain is then taxed at the trust level under the rules of the trust’s state. This requires careful structuring (the trust must be a non-grantor trust for state tax purposes; some states use throwback rules) and several years of operating history before the sale.

Asset sale vs. stock sale: the negotiation that saves $200K-$1M

Almost every business sale is structured as either an asset sale or a stock sale. The buyer’s preference and the seller’s preference are usually opposite, which means the LOI negotiation is where the structure gets resolved — and where hundreds of thousands of dollars of tax can shift.

Why buyers prefer asset sales. In an asset sale, the buyer gets a stepped-up basis equal to the purchase price allocated across the assets. They get depreciation deductions on the new basis (often $100K-$500K of annual deductions for years). They avoid inheriting the seller’s historical liabilities. The tax benefit to the buyer can be 5-10% of purchase price in present value.

Why sellers prefer stock sales. In a stock sale, the entire gain is capital gain (assuming long-term holding). There’s no double-taxation issue (relevant for C-corps). No depreciation recapture is triggered. The single-level capital tax treatment can save 5-15% of total tax compared to an asset sale of the same business.

The negotiated outcome. If buyer insists on asset structure, seller should ask for a tax gross-up — typically 5-15% of purchase price added on top to compensate for the seller’s tax differential. The exact gross-up depends on entity type, asset mix, and state. For a C-corp where the gross-up is needed to bridge the double-taxation gap, the percentage can be higher.

Allocation of purchase price. If the deal is an asset sale, the IRS Form 8594 allocation across asset classes determines tax treatment. The seller wants allocation tilted toward Class VII (goodwill, capital gain) and away from Class V (equipment, depreciation recapture) and any non-compete payments (ordinary income). The buyer’s preference is the opposite. Allocations have to reconcile (both sides file the same Form 8594) so this becomes a real negotiation, often worth 5-10% of total tax.

Earnouts, rollover equity, and seller financing: timing the recognition

Not all of the purchase price needs to be received at closing. Earnouts (contingent payments tied to future performance), seller notes (deferred fixed payments), and rollover equity (equity in the buyer’s entity) are all structures that defer or restructure tax recognition. Each has trade-offs.

Earnout taxation. Earnouts are generally taxed under the installment sale method — gain is recognized proportionally as payments are received. The benefit: deferral of tax on the earnout portion. The risk: if the earnout is structured around personal employment metrics, the IRS can recharacterize it as compensation (ordinary income at 37%+) rather than purchase price (capital gain at 20%). Tie earnouts to enterprise-level revenue or EBITDA metrics, not to personal performance.

Rollover equity. Rolling 10-30% of equity into the buyer’s entity defers tax on the rolled portion. Common with PE buyers. The rollover is structured as a tax-deferred exchange (Section 351, Section 368) and the gain on the rolled equity isn’t recognized until the new entity is exited. Benefits: tax deferral, second bite at growth, alignment with the buyer. Risks: locked into the buyer’s thesis, illiquid for 3-7 years, exposed to new entity performance.

Seller notes. A seller note is deferred fixed payment (typically 5-20% of price, paid over 3-7 years with interest). The tax benefit is installment-sale deferral on the note portion. The risk is collection — if the buyer struggles, the note may not be paid. Structure protections: personal guarantees from the buyer’s principals, security interest in the assets sold, acceleration on default, escrow on a portion.

Charitable remainder trust (CRT). If part of the proceeds is destined for charity anyway, contributing equity to a CRT before the sale lets you avoid capital gains on the contributed portion entirely (the CRT sells without paying tax) and receive a current-year charitable deduction for the present value of the remainder. The CRT then pays you an income stream for life or a term of years. Requires a qualified appraisal and 6-12 months of pre-sale planning.

ESOPs and Section 1042: full tax deferral for the right business

An employee stock ownership plan (ESOP) is a sale to a trust that holds equity for the benefit of employees. For C-corp owners, Section 1042 of the Internal Revenue Code allows full deferral of capital gain on the sale to the ESOP if proceeds are reinvested in qualified replacement property (QRP — typically U.S. operating company stock or bonds) within 12 months of the sale.

When ESOPs make sense. The business has predictable cash flow that can service ESOP debt. Tax-favorable treatment is valuable to the seller. The seller is willing to accept slightly lower headline value (typically 5-15% below strategic-buyer multiples) in exchange for the structure. The seller wants to preserve culture and employees over maximum price.

Section 1042 mechanics. After selling C-corp stock to an ESOP that owns at least 30% of the company, the seller has 12 months to reinvest the proceeds in QRP. The QRP must be domestic operating company stock or bonds (not Treasuries, not REITs, not mutual funds — but specific qualifying issuers). Holding QRP defers the gain entirely until the QRP is sold. Holding QRP until death achieves a step-up in basis and full forgiveness of the deferred gain.

ESOPs as one of several alternatives. ESOPs aren’t for every owner. They’re slower to close (6-12 months from kickoff), more expensive in transaction costs ($150K-$500K typical), and require the business to operate post-sale with ESOP debt service for 5-10 years. But for the right C-corp owner with the right business, the after-tax outcome can rival or exceed a full strategic sale — and for owners who care about culture, the structural fit is unmatched.

Qualified opportunity zones: post-sale deferral and step-up

Qualified opportunity zones (QOZ) were created by the 2017 Tax Cuts and Jobs Act to encourage investment in distressed communities. For sellers of appreciated assets (including business sales), a QOZ investment lets you defer capital gains tax on the original sale by reinvesting the gain into a Qualified Opportunity Fund (QOF) within 180 days. If the QOF is held for 10+ years, the appreciation on the QOF investment itself is fully excluded from tax.

QOZ mechanics. Within 180 days of selling your business (or other appreciated asset), invest the gain (not the entire proceeds, just the gain portion) in a QOF. The original gain’s tax is deferred until the earlier of December 31, 2026 (under current rules) or sale of the QOF investment. If the QOF investment is held for 10+ years, the appreciation on the QOF itself is tax-free. Combined effect: deferral of original gain plus potential elimination of new appreciation.

Trade-offs. QOZ investments have to be in qualified zones (specific census tracts) with substantial improvement requirements. Most QOZ funds are real estate or operating businesses in qualifying zones. The 10-year hold requirement means the investment is illiquid. Returns are not guaranteed and many QOZ funds have underperformed. The tax benefit is real but the investment risk has to be evaluated independently.

When QOZ makes sense. You have a meaningful capital gain you want to defer. You’re comfortable with a 10-year illiquid investment. You can identify a QOF with credible underwriting and a real opportunity (not just tax-driven structure). The post-sale 180-day window is short, so the QOZ planning has to be done in advance — ideally with the QOF identified and ready to receive funds at closing.

Working with your CPA, attorney, and advisor team

Pre-sale tax planning is not a solo project. It requires coordination among your CPA (tax modeling and compliance), tax attorney (entity work, trust structures, complex strategies), wealth advisor (post-sale investment strategy and estate planning), and M&A advisor or buy-side partner (deal structure and negotiation). Each professional has a role and the work has to integrate.

Hire specialists, not generalists. The CPA who’s done your annual returns for 20 years may not be the right CPA to plan a $5M+ business sale. Tax planning at this scale involves QSBS rules, state residency planning, asset/stock allocation, installment sales, and gift/estate strategies that are specialty skills. Hire a transaction-focused CPA in the 12-month window before the sale — either as primary or as a co-advisor with your existing CPA.

Coordinate the work. Tax attorney and CPA often disagree on aggressive vs. conservative strategy. M&A advisor and CPA often disagree on negotiating priorities. Wealth advisor and tax attorney often disagree on trust vs. direct ownership. Schedule joint meetings (or at minimum joint email threads) so the team is calibrated on goals and tradeoffs. Disjointed advice is the second-most expensive mistake after late-start planning.

Where a buy-side partner fits. A buy-side partner like CT Acquisitions sits between you and the buyers — we already know the 76+ active LMM buyers and their typical deal structures. We can tell you in advance which buyers prefer stock vs. asset, which support rollover equity, which accept seller notes, which have ESOP-friendly track records. That intelligence shapes which buyers you talk to and what tax structure the deal will likely use — informing your tax planning months before any LOI.

Conclusion

Tax planning at the LOI stage is too late for the moves that matter most. QSBS qualification, state residency, entity conversions, family gifting — these all require 12-60 months of runway. The owners who net 80-85% of their sale price after tax are the ones who started the structural work 12-24 months before they ever talked to a buyer. The owners who net 60-70% are the ones who waited until the deal was on the table. The 12-month checklist above is the framework; your CPA and tax attorney are the executors. The earlier you start, the more levers stay available. And if you want to talk to someone who knows the buyers personally instead of running a 9-month auction, we’re a buy-side partner — the buyers pay us, not you, no contract required.

Frequently Asked Questions

When should I start tax planning for a business sale?

12-24 months before you intend to go to market is the typical sweet spot. Some structural moves (QSBS qualification, state residency, entity conversions) need 5+ years of lead time. The rule of thumb: as soon as selling becomes a real possibility within 5 years, schedule a tax planning review with a transaction-focused CPA and tax attorney. The cost is low; the upside on a $5M+ sale is typically $250K-$1M of net proceeds.

What’s the single biggest tax-saving move for most owners?

Entity structure paired with QSBS qualification is the most powerful single lever. A C-corp owner whose stock qualifies for Section 1202 can exclude up to $10M (or 10x basis) of gain from federal tax entirely — saving up to $2.38M per shareholder. The catch: 5-year holding period and several technical qualifications. For owners who don’t qualify, state residency planning (CA → FL/TX) is typically the second-biggest move, worth $400K-$665K on a $5M gain.

How much does state of residency actually save?

On a $5M long-term capital gain, California residents pay $665K in state tax (13.3%). Florida, Texas, Tennessee, Wyoming, and other no-tax states pay $0. New York is $545K (10.9%). New Jersey is $537K (10.75%). The savings are real but require establishing actual residency — physical residence, voter registration, drivers license, days-in-state, family ties — not just a mailing address. States like California aggressively challenge tax-driven residency changes.

Should I convert my LLC to a C-corp before selling for QSBS?

Maybe, but the conversion has to happen at least 5 years before the sale (the QSBS holding period) and the corporation has to have under $50M in gross assets at issuance. The conversion can be done via Section 351 contribution and starts a fresh QSBS clock. It’s a real planning option for owners who are 5+ years from sale — but it’s never the only consideration; LLC vs C-corp also affects ongoing operations, distributions, and other tax mechanics.

What’s the difference between an asset sale and a stock sale for tax?

Asset sale: buyer purchases specific assets, gets stepped-up basis for depreciation, seller recognizes gain on each asset class (some ordinary income, some capital gain, depreciation recapture, etc.). Stock sale: buyer purchases the equity, no step-up in basis for buyer, seller recognizes single capital gain. Sellers typically prefer stock; buyers typically prefer assets. The negotiation is worth 5-15% of purchase price — often resolved through a tax gross-up if asset structure is required.

How do I allocate purchase price across asset classes in an asset sale?

IRS Form 8594 requires allocation across 7 classes: Class I (cash), Class II (CDs and securities), Class III (accounts receivable), Class IV (inventory), Class V (equipment), Class VI (intangibles other than goodwill), Class VII (goodwill). Sellers want allocation toward goodwill (capital gain). Buyers want allocation toward equipment (depreciation deductions). Both sides must file the same Form 8594. The negotiation typically happens at LOI — with a CPA modeling the after-tax impact for both sides.

Are earnouts taxed as ordinary income or capital gain?

Generally capital gain under the installment sale rules — gain is recognized as payments are received. But the IRS can recharacterize earnouts as compensation (ordinary income at 37%+) if they’re tied to the seller’s personal services or employment. To preserve capital treatment: tie earnouts to enterprise-level metrics (revenue, EBITDA), not personal performance, and don’t make payment contingent on the seller’s continued employment beyond reasonable transition periods.

Can I defer tax by rolling equity into the buyer’s entity?

Yes, when structured as a tax-deferred reorganization (Section 351, Section 368). Common with PE buyers. Typically 10-30% of equity rolls; 70-90% is cashed out. The rolled portion defers tax until the new entity is exited (often 5-7 years later). Benefits: tax deferral, second bite at growth, alignment with the buyer. Risks: locked into the buyer’s thesis, illiquid, exposed to new entity performance. The structuring rules are technical; involve a tax attorney.

What is QSBS Section 1202 and do I qualify?

Section 1202 lets shareholders of qualified small business stock exclude up to $10M (or 10x basis) of gain from federal capital gains tax. Requirements: domestic C-corp, under $50M gross assets at issuance, qualified trade or business (excludes most professional services, hospitality, finance), 5-year holding period, original-issuance acquisition. On a $10M sale of qualifying stock, the savings can be up to $2.38M per shareholder. Multi-shareholder businesses can stack the exclusion across family members and trusts.

Should I do an ESOP instead of a strategic sale?

Maybe, if the structural fit is right. ESOPs work for C-corps with predictable cash flow that can service ESOP debt, owners who value tax deferral (Section 1042 allows full federal deferral if proceeds reinvest in qualified replacement property), and owners who prioritize culture and employees over maximum price. Trade-offs: ESOPs typically pay 5-15% below strategic-buyer multiples, transaction costs are higher ($150K-$500K), and the business has to operate post-sale with ESOP debt for 5-10 years. Run the after-tax math; for the right business, ESOP can rival strategic sale outcomes.

Can I avoid capital gains tax with an opportunity zone investment?

Defer, not avoid. Within 180 days of selling appreciated assets (including a business), reinvest the gain into a Qualified Opportunity Fund (QOF). The original gain’s tax is deferred until December 31, 2026 (under current rules) or sale of the QOF, whichever is earlier. Hold the QOF for 10+ years and the appreciation on the QOF itself is tax-free. Trade-offs: 10-year illiquidity, investment risk, must be a real qualifying fund. Plan in advance — 180 days is a tight window post-sale.

Do I need a sell-side QoE before going to market?

If your business is over $1M EBITDA with material add-backs ($100K+), yes. Sell-side QoE costs $25-75K and pre-validates your reported EBITDA against buyer-grade scrutiny. From a tax perspective, it surfaces add-backs and one-time items that will become negotiating points and prevents mid-deal re-trades. Sellers who run sell-side QoE typically face 80%+ fewer add-back disputes during the buyer’s QoE — translating to higher LOI prices and fewer surprises.

How is CT Acquisitions different from a sell-side broker or M&A advisor?

We’re a buy-side partner, not a sell-side broker. Sell-side brokers represent you and charge you 8-12% of the deal (often $300K-$1M) plus monthly retainers, run a 9-12 month auction process, and require 12-month exclusivity. We work directly with 76+ buyers — search funders, family offices, lower middle-market PE, and strategic consolidators — who pay us when a deal closes. You pay nothing. No retainer, no exclusivity, no contract until a buyer is at the closing table. You can walk after the discovery call with zero hooks. We move faster (60-120 days from intro to close) because we already know who the right buyer is rather than running an auction to find one.
