Tax Planning for Business Sale: What Buyers Know

Most sellers spend years building their business and about three weeks thinking about taxes before they sell. That is backwards.

The structure of your deal determines how much of the purchase price you actually keep. A $2M sale can net you $1.4M or $1.7M depending on how the transaction is set up. Buyers know this. Their advisors are optimizing the structure from day one, and yours should be too.

Here is what serious buyers think about when they sit down to structure an offer, and what it means for your tax position as a seller.

How Deal Structure Drives Your Tax Bill

Tax planning for a business sale starts with one question: asset sale or stock sale?

In an asset sale, the buyer purchases the individual assets of your business. Equipment, customer lists, goodwill, inventory. In a stock sale, the buyer purchases your ownership interest directly. Most SBA-financed deals are structured as asset sales because SBA lenders require it. That matters because the two structures produce very different tax outcomes.

Different asset classes get taxed at different rates in an asset sale. Ordinary income rates apply to inventory, accounts receivable, and depreciation recapture on equipment. Capital gains rates (currently 15% to 20% for most sellers at the federal level) apply to goodwill and going-concern value.

For most small businesses, the majority of the purchase price lands in goodwill. That works in your favor.

Stock sales, on the other hand, typically push most of the gain into capital gains territory. Sounds better on paper. But SBA lenders almost never finance stock purchases, which means you are unlikely to attract qualified buyers if you insist on that structure.

Understanding this dynamic early gives you room to plan before a deal is on the table.

Purchase Price Allocation: The Negotiation Inside the Negotiation

After the headline number is agreed on, buyers and sellers negotiate how that number gets allocated across asset classes. This is the purchase price allocation, and it has real tax consequences for both sides.

Buyers want more value pushed into depreciable assets (equipment, non-competes, customer lists) because they can write those off quickly after closing. Sellers generally want more allocated to goodwill because goodwill gets capital gains treatment rather than ordinary income treatment. These interests directly conflict.

Both parties file IRS Form 8594 after closing, and both forms need to agree on the allocation. So this is a negotiated point. Not an afterthought.

If you let the buyer’s attorney draft the purchase price allocation without input from your CPA, you will almost certainly end up with more ordinary income than necessary. Get your tax advisor involved before the letter of intent is signed.

A rough example: say you are selling a commercial cleaning company for $1.5M. The buyer proposes allocating $400K to equipment and fixtures (depreciable, triggers depreciation recapture at ordinary income rates) and $1.1M to goodwill (capital gains rates). Your CPA might counter with $250K to equipment and $1.25M to goodwill. That $150K shift from ordinary income treatment to capital gains treatment can meaningfully reduce your tax liability depending on your depreciation history.

How the Seller Note Affects Your Tax Position

Most SBA-financed deals include a seller note. The structure we achieve on more than 90% of our deals is a 10-year full standby note at 0% interest. During the standby period, you receive no payments.

Zero interest. Zero payments. For 10 years.

From a tax standpoint, this creates what the IRS calls an installment sale. Under installment sale treatment, you recognize income as you receive payments rather than all at once in the year of closing. If your seller note goes on standby for 10 years, you are deferring the income allocated to that portion of the purchase price for a full decade.

That is a real tax deferral benefit, especially if you expect to be in a lower bracket in later years.

There is a catch, though. You can elect out of installment sale treatment if it works better for your situation. Some sellers do this when they have capital loss carryforwards they want to offset against the gain in the year of sale. This is a CPA conversation, not a boilerplate decision.

One more thing worth flagging here: interest-free seller notes can trigger IRS imputed interest rules (the applicable federal rate, or AFR, published monthly by the IRS is the benchmark). The IRS may require you to report a minimum interest income even if the note carries 0%. Your tax advisor needs to account for this in your planning.

State Taxes Are a Bigger Factor Than Most Sellers Realize

Federal capital gains get most of the attention. State taxes often get ignored until after closing.

States tax business sale gains differently. Some, like Florida and Texas, have no individual income tax, which makes them favorable for sellers. Others, California and New York in particular, tax capital gains as ordinary income at state rates that can reach 13% or higher.

If you have flexibility in your residency, this matters. Some sellers establish residency in a lower-tax state well before they list. The IRS and state revenue agencies scrutinize these moves, so it requires genuine relocation. Not a paper change.

And if your business operates in multiple states, the gain may need to be apportioned. Some states have source-based taxation rules that can tax part of your gain even if you do not live there. Your CPA needs to map this out well before closing.

None of this gets sorted out in the week before the deal closes.

The Qualified Small Business Stock Exclusion

If your business is a C-corporation that meets certain IRS criteria, you may qualify to exclude up to 100% of the gain on the sale under Section 1202. This is the Qualified Small Business Stock provision, or QSBS.

The requirements are strict:

Gross assets must have been under $50M when the stock was issued
You must have held the stock for more than five years
The business must be in a qualifying industry (most professional services and financial companies are excluded)

If you qualify, this is one of the most valuable tax provisions available to business sellers. It can eliminate federal capital gains tax on millions of dollars of gain.

Most sellers of small businesses operate as S-corps or LLCs, so QSBS does not apply to them. But if you built a C-corp and held the stock from the early days, get a qualified opinion on this before you do anything else. The planning window can close fast if you convert entity type or restructure before a sale.

Closing Date Strategy: December vs. January

Closing in December versus January can have real tax consequences.

Close on December 28th and you recognize the gain in the current tax year. Close on January 3rd and you defer it twelve months. That is it. Six days apart, twelve months of difference.

That extra year gives you time to plan. You can max out retirement contributions, harvest capital losses in your investment accounts, or structure charitable giving strategies. Twelve months of planning room is worth more than most sellers realize.

Buyers generally do not care much about which side of the year-end the close falls on. This is a lever that is entirely yours. Bring it up early in negotiations. It rarely affects the purchase price and can meaningfully affect your after-tax proceeds.

What Qualified Buyers Already Know About Tax Planning for Business Sale

So that covers the structural side, the timing, and the state-level considerations. Here is the part that ties it all together.

Experienced buyers and their advisors have structured dozens of these transactions. They know which allocations favor them, which structures trigger depreciation recapture, and where sellers tend to leave money on the table.

This is not said to alarm you. It is said because sellers who engage a qualified CPA (one with M&A transaction experience, not just a generalist) before the LOI is signed consistently end up with better after-tax outcomes.

The gap between a well-structured deal and a poorly structured one at the $1.5M to $3M sale price range can easily be $100K to $200K in after-tax proceeds. That is real money.

Regalis-backed buyers come to the table with proper deal structure already built in. There is no cost to you as a seller. No commissions, no fees, no obligation. But that also means the buyer’s side is well-advised. Yours should be too.

Frequently Asked Questions

What is the difference between capital gains tax and ordinary income tax when selling a business?

Capital gains tax applies to the sale of assets held for more than one year, including goodwill, and is currently taxed at 15% to 20% for most sellers at the federal level. Ordinary income tax applies to items like depreciation recapture on equipment and inventory, taxed at your marginal rate (up to 37% federally). Minimizing ordinary income in the purchase price allocation is one of the main goals of pre-sale tax planning.

How does an installment sale affect taxes when selling a business?

An installment sale lets you recognize gain as you receive payments rather than all at once in the year of closing. If your deal includes a seller note on standby for several years, you defer the income allocated to that portion of the sale price. This can reduce the tax hit in the sale year and spread recognition into years when you may be in a lower bracket. Your CPA should evaluate whether electing into or out of installment treatment makes more sense for your situation.

When should I start tax planning before selling my business?

Ideally, 12 to 24 months before you list. Some strategies, like shifting income between tax years, establishing state residency, or restructuring entity type, require time to implement properly. Starting the conversation with a qualified CPA well before a buyer is involved gives you the most options and the most flexibility.

Does the type of business entity affect taxes on a sale?

Yes, significantly. S-corps, LLCs taxed as pass-throughs, and C-corps all have different tax treatment on a sale. C-corp owners may qualify for the Section 1202 QSBS exclusion. S-corp and LLC sellers typically face pass-through taxation on the gain. The entity type also affects whether buyers can do an asset purchase with a Section 338(h)(10) election, which has its own tax implications.

How does a seller note at 0% interest get treated for tax purposes?

The IRS has imputed interest rules that may require you to report a minimum amount of interest income on a below-market or interest-free note, even if you are not receiving cash payments during a standby period. The applicable federal rate published monthly by the IRS is the benchmark. Your tax advisor needs to account for this in your return for each year the note is outstanding, including standby years when no payments are being made.
