A written map of which year each part of your sale price is taxed, and how, is what tax planning for a business sale at Apollon Wealth Management gives owners preparing to sell. The core work takes about ninety days from the first meeting. It pays most when it starts before the letter of intent is signed, because the asset vs. stock structure, the earnout share and the price allocation are hard to reopen after that.
Most owners we meet have put this off for years. The business paid the bills, a sale felt like something for later, and then a competitor called. Now there's a letter on the desk, a reply date, and a CPA who hasn't seen the terms yet.
When does a buyer's letter make sale tax planning urgent?
Latoya, a hypothetical 51-year-old owner of a wholesale bakery, is holding a competitor's letter of intent: $3.2 million, with 30 percent of it ($960,000) paid later as an earnout. For her, sale tax planning means deciding before she signs how the price splits into asset classes and which year each payment lands.
Equipment recapture and any non-compete are taxed as ordinary income; goodwill is generally capital gain. It starts to matter the moment a buyer names a price, because the letter's structure terms are the hardest to change later.
Papers Apollon Wealth Management hands you, and when
Latoya asked what she would actually hold in her hands. Here is the list, in the order it arrives.
- By week two: a single page listing the sale's tax decisions in deadline order (letter of intent terms, allocation, closing date, estimated payments), with who decides each one: you, the CPA or the deal attorney.
- By week six: a draft allocation schedule showing each asset class, its tax character and its tax cost at illustrative rates. Your CPA checks it against what both sides will report on IRS Form 8594.
- By week ten: a year-by-year income table for the sale year and each earnout year, with estimated tax dates. It includes the safe-harbor amount (110 percent of last year's tax when prior-year AGI was over $150,000).
- Before closing: a written plan for retirement accounts covering solo 401(k) contributions while bakery earnings still exist and the years for any Roth conversion, plus the cash reserve to hold back for April.
Once the deal closes, how long does the sale tax plan stay current?
The plan stays current until the last earnout or note payment has been taxed and reported, and we update it at each progress meeting until then. For Latoya, that means the two earnout years plus the filing year after. We call an extra meeting if the buyer revises the allocation, an earnout target is missed or renegotiated, you move states, or Congress changes a rate the plan relies on.
The first ninety days of sale tax planning, week by week
We take one decision at a time, in order of deadline, and you see the figures for each before you choose. Nothing gets signed off until its tax cost is on the page.
Weeks 1 to 2: gather and sort
Weeks 3 to 6: model the terms
Weeks 7 to 10: build the income table
Weeks 11 to 13: sign off
How much does the timing of each move save Latoya, and why do Raj and Sharon get a different answer?
For Latoya, converting $300,000 to Roth after the earnout instead of during it saves a hypothetical $35,000, because her marginal rate falls from 35 to 37 percent in the sale years to 24 percent afterward. If a move only pushes income to a later year at the same rate, she pays the same tax later.
A hypothetical person, Latoya, asks how to keep more of $3.2 million. She plans to convert $300,000 of her $550,000 solo 401(k) to Roth. Plan A converts $100,000 a year in the sale year and the two earnout years. Plan B waits until the earnout is paid, then converts $100,000 a year in years four through six, when her only income is modest investment income. For illustration, assume marginal rates of 37 percent in the sale year (equipment recapture), 35 percent in the earnout years (a consulting salary from the buyer) and 24 percent afterward.
Plan A costs $37,000 + $35,000 + $35,000 = $107,000. Plan B costs 3 × $24,000 = $72,000, so waiting saves $35,000. In the table, only the middle row has a known, lower cost. Leaving the money pre-tax has no price yet, because it depends on her withdrawals and on RMDs from 75.
Before 59½, cover a conversion's tax bill with sale proceeds, not by withholding from the account. The IRS treats withheld money as a distribution, and it can carry the 10 percent early-withdrawal penalty. An earnout may never be paid in full, and invested proceeds can lose value, so keep the April cash reserve real.
Latoya decided to make the full solo 401(k) contribution in her last year of bakery earnings (the 2026 IRS employee deferral limit is $24,500, plus the $8,000 catch-up at 50 and over) and to make no conversions until the earnout ends.
Rule of thumb: keep ordinary income you control (Roth conversions, bonuses, big equipment write-offs) out of the closing year and the two earnout years that follow. Moving income to a later year saves tax only if your rate drops by then: each 10-point drop saves $10,000 for every $100,000 you move.
One mistake looks careful. Buying $300,000 of new ovens and delivery vans the year before the sale and expensing them all at once means that, if the buyer pays for that equipment, the deduction returns as ordinary recapture in the sale year. Saved at an assumed 32 percent ($96,000) and recaptured at 37 percent ($111,000), it costs $15,000 more than it saved.
Raj and Sharon, hypothetical, 47 and 45, arrive with the same question and get a different answer. Raj is on the buying side of his 50/50 partner's $2 million exit: if the company redeems the shares his basis doesn't rise, but if he buys them himself it rises by $2 million, so their first decision is the purchase structure, not account timing; the funding question belongs to buy-sell agreement funding.
This is not a service for owners who haven't decided whether to sell. The timing math rests on assumed rates; if Congress changes brackets, or Latoya's income after the earnout runs higher than planned, waiting saves less. And no tax plan can rewrite a structure already signed in the purchase agreement.
The conversion arithmetic
Raj and Sharon's different first decision
Don't sign a letter of intent until you've seen how its structure terms (asset vs. stock, earnout share, price allocation) change your tax cost. They are the hardest terms to reopen.
| Option | Tax cost (illustrative) | Years taxed | Main risk |
|---|---|---|---|
| Convert in sale and earnout years | $107,000 | Years 1 to 3 | Stacks on sale income |
| Convert after earnout ends | $72,000 | Years 4 to 6 | Rates may change by then |
| Leave it pre-tax | Not known yet | Withdrawals; RMDs from 75 | Larger RMDs later |
If your first sale tax meeting is next month
If this is you (letter of intent in hand or expected), start with the paperwork. Gather the letter or term sheet and three years of returns. Then add the depreciation schedule, which shows your recapture exposure, and the year-end statement for each retirement account.
In the meeting, Apollon Wealth Management lists the sale's decisions with their deadlines and gives a first rough tax cost of the deal as offered, at illustrative rates, for your CPA to check.
You leave with the decision list in deadline order and a name next to each decision. Meetings are by video call or phone. The client minimum is $500K in investable assets (Latoya's $550,000 solo 401(k) qualifies). Every fee appears in the client agreement, and nothing beyond it is charged.
A move that changes the rate saves tax. A move that changes only the year just shifts it.
Your questions about tax planning for a business sale, answered
My daughter starts college in two years; will the sale gain show up on her financial aid forms?
Yes, probably. Aid forms look at income from an earlier tax year, so a sale gain reported in that year can count against you, and the business sale itself may count as an asset. Ask us to place the sale and earnout years against the aid calendar before you sign.
Is it better to send a large estimated tax payment right after closing or wait until April?
Paying estimated tax by the IRS quarterly dates avoids underpayment penalties, so waiting until April is usually costly. The safe harbor is 110 percent of last year's tax when prior-year AGI was over $150,000. Our income table sets each date and amount, and your CPA confirms it.
How long do I need to keep the records from my business sale?
Keep sale records at least as long as the IRS can review the return, generally three years, and longer for an earnout or note that is still being paid. We'd keep the purchase agreement, allocation schedule and Form 8594 copy until the last payment is reported, then a few years more.
Can I still contribute to my solo 401(k) after I sell the bakery?
Only while you have self-employment earnings from the business. Once the bakery is sold and that income ends, the contribution room closes. That's why we plan the full contribution (the 2026 IRS deferral limit is $24,500, plus $8,000 catch-up at 50 and over) for your last year of earnings.
Does a consulting contract from the buyer get taxed differently from the purchase price?
Yes. Consulting pay is ordinary income, and may also carry self-employment tax, while much of the purchase price for goodwill is generally capital gain. A non-compete payment is ordinary income too. How the buyer labels each dollar in the agreement matters, so we raise it before signing.
Does moving to another state after closing lower the tax on my sale?
Sometimes, but not reliably. Some states tax a sale gain and some don't, and the state where the gain arises can still claim it. Earnout payments may follow different rules by state. Check your state's rules with your CPA before moving; we'd add a move to the plan as a trigger for an extra meeting.
