The costliest mistakes selling a small business happen before closing, and Apollon Wealth Management finds most of them in three places: an unpriced letter of intent, a vague working capital clause and a long noncompete. Every $100,000 of price labeled as a noncompete instead of goodwill costs about $15,000 more in federal tax, assuming a 35 percent ordinary rate and a 20 percent capital gains rate for illustration. So what should you actually check before you sign a buyer's draft? At Apollon Wealth Management, we put each decision in deadline order and attach an after-tax number to it before the owner answers.

Move $150,000 from a noncompete back to goodwill and you save about $22,500 of federal tax at 35 and 20 percent rates. Do that before the letter is signed, not after.

When the partner wants out and a buyer's letter arrives
Raj, 47, co-owns an IT managed-services firm 50/50 with an unrelated partner who wants out within two years. Their buy-sell agreement has no funding behind a $2 million buyout. So when a larger managed-services firm puts $4 million for the whole company on the table in a draft letter, structured as an asset sale, it looks like the cleaner exit. Raj's half is $2 million. (This is a hypothetical household, used for the rest of the article.)
Apollon Wealth Management writes the decisions in deadline order: the exclusivity window in the draft letter, the purchase agreement and its allocation, the closing date, and the tax return for the sale year. Each one gets its own after-tax number before anyone decides.
His wife Sharon, 45, and their three children under 15 depend on Raj's income after closing. That makes the noncompete a household question. The tax answer is only part of it.
Signing the letter before anyone prices the tax
A letter of intent is nonbinding, so many first-time sellers assume the details can be fixed later. They can't, not really. The structure (asset sale), the price mix and the exclusivity period rarely move once the buyer's lender and lawyers start work, and after closing the allocation can't be changed at all. Before Raj countered, Apollon Wealth Management put an after-tax figure next to the $2 million headline for each label in the draft.
How much does a noncompete label cost Raj each year?
Every dollar labeled as a noncompete instead of goodwill costs a seller the gap between the ordinary and capital gains rates, about 15 cents per dollar at the rates assumed here. Payments for a noncompete are ordinary income to the seller. Goodwill in an asset sale is generally capital gain.
The buyer gains nothing from the switch. In an asset sale it amortizes both over 15 years as Section 197 intangibles, so the label only shifts tax onto Raj.
Here is the math for a hypothetical household. Raj's draft labels $200,000 of his $2 million share as a five-year noncompete, paid $40,000 per year. Assume a 35 percent ordinary rate and a 20 percent capital gains rate, for illustration. Each $40,000 payment costs $14,000 in tax. The same dollars as goodwill cost $8,000. That's $6,000 more every year. The gap reaches $12,000 after two years, $18,000 after three, $24,000 after four and $30,000 after five.
The table starts with the $100,000 case, and the extra tax cost rises by the same 15 cents for every dollar added to the noncompete label. If your own draft puts 5 to 20 percent of your share on the noncompete, find the matching row and you can see roughly what that label costs you.
What to ask the buyer's CPA
Rule of thumb: in an asset sale, every dollar moved from goodwill to a noncompete costs you the gap between your ordinary and capital gains rates. Ask for any figure above what the restriction is really worth to be moved back before you sign the letter.
| Amount labeled noncompete | Tax if goodwill (20%) | Tax if noncompete (35%) | Extra tax cost |
|---|---|---|---|
| $100,000 (5% of share) | $20,000 | $35,000 | $15,000 |
| $200,000 (10% of share) | $40,000 | $70,000 | $30,000 |
| $400,000 (20% of share) | $80,000 | $140,000 | $60,000 |
What age is too young for a five-year noncompete?
A noncompete is too long when it keeps you out of work you expect to do again. At 47, a five-year term keeps Raj out of IT until 52, and his oldest child starts college inside that window. A longer term can support a higher price, but he gives up his field to get it.
So who should accept which? A 68-year-old who plans to stop working gives up little with a long term. An owner in his 40s who expects to earn again should trade price for a shorter term.
Raj and Sharon (hypothetical) countered with a three-year term and $50,000 on the noncompete, moving $150,000 back to goodwill. At the assumed rates that saves $22,500 of federal tax compared with the draft ($150,000 times 15 cents). Raj also agreed with Sharon that three years was the longest they'd accept.
The working capital line nobody defined
A few months after closing, the buyer's true-up statement claims receivables and cash came in $120,000 below a "normal level of working capital" that the letter never defined. Raj's half, $60,000, comes out of escrow.
The tax angle offers no relief. A price cut lowers Raj's capital gain too, so at an assumed 20 percent rate the after-tax loss is about $48,000 ($60,000 minus $12,000). The tax shrinks with the price, and nothing is saved.
The fix belongs in the letter itself. Define the target as a trailing twelve-month average and name who calculates it. Then ask the buyer how the peg is computed. "We'll agree on it at closing" is the answer that should worry you.
Where Raj's numbers wouldn't hold
When the deal is a stock sale, the buyer can't amortize what it pays for the shares, so it has a real tax reason to push value onto the noncompete and will resist moving it. A seller carrying a note still pays Section 1245 recapture on depreciated equipment in the year of sale. A seller with modest income that year may face a smaller gap between the two rates. And an allocation has to reflect real value, or the IRS can challenge it. A noncompete set at zero when the seller really could compete is not a safe answer either. The rates here are illustrations and leave out state tax.
What Raj checked alone and what he brought to Apollon Wealth Management
Raj could read the draft for three labels on his own: the dollar figure and length of the noncompete, the definition of working capital, and asset versus stock structure. Pricing each label against Sharon's household budget and the partner's two-year deadline, together with their CPA, is where a conversation with Apollon Wealth Management earned its time. Investment and tax outcomes are never certain, and any sale proceeds you reinvest can lose value.
A price cut after closing lowers your tax too, but a $60,000 cut still costs about $48,000.
Your questions about mistakes selling a small business, answered
How much of my sale price can be labeled as a noncompete before the IRS questions it?
The IRS sets no fixed percentage. The allocation has to reflect real value, so a figure far above what the restriction is worth, or a zero when you could really compete, invites a challenge. Both sides report the split on Form 8594, and the numbers should match.
What happens if the working capital at closing comes in below the target in the purchase agreement?
The purchase price is usually reduced dollar for dollar by the shortfall, often taken from escrow. In a hypothetical 50/50 sale, a $120,000 shortfall costs a half owner $60,000. Defining the target and who calculates it in the letter of intent limits disputes.
When does the purchase price allocation get settled, in the letter of intent or in the purchase agreement?
Ideally the letter sets the principles and the purchase agreement fixes the dollar figures before closing. Waiting until after closing is the worrying answer, because both sides file Form 8594 with the return for the sale year and the figures should match.
Does a price cut after closing lower my capital gains tax?
Generally yes, because a price reduction lowers the gain you report. But the tax saving only offsets part of the loss. At an assumed 20 percent rate, a $60,000 cut costs about $48,000 after tax, so a price cut is never a tax win.
Should my spouse read the buyer's draft letter before I send a counteroffer?
Yes, especially if your spouse and children depend on your income after closing. A noncompete length, an escrow holdback or a note can change household cash flow for years. Reading the draft together lets you set the limits you won't cross before you reply.
