Business Sale Tax Estimator

Get a detailed estimate of what you'll owe in federal and state taxes when you sell your business — broken down by capital gains, ordinary income, depreciation recapture, and more.

For estimation purposes only. This tool provides a rough tax estimate based on the information you enter. Actual taxes depend on many factors including your specific tax situation, deductions, and state rules. Always consult a CPA or tax advisor before making decisions about selling your business.

Step 1 — Sale Structure

The structure of your sale has the biggest single impact on your tax bill. Asset sales and stock sales are taxed very differently.

Most common for small businesses

Asset Sale

You sell the business's assets (equipment, goodwill, inventory, etc.). Different asset types are taxed at different rates. Buyers strongly prefer this structure.

Better for sellers, tax-wise

Stock / Equity Sale

You sell your ownership shares in the company. Most of the gain is taxed at long-term capital gains rates. Sellers often prefer this structure.

Your sale details

Gross Sale Price — total purchase price

Your Tax Basis — what you originally paid / invested

Your original cost plus any capital improvements. If you built the business from scratch, this is often low — meaning a larger taxable gain.

Years Owned

Businesses held over 1 year qualify for long-term capital gains rates — significantly lower than ordinary income rates.

Your Filing Status

Estimated Annual Household Income — excluding business sale proceeds

Your income level determines which federal capital gains tax bracket you fall into (0%, 15%, or 20%).

Step 2 — Asset Allocation

In an asset sale, different types of assets are taxed at different rates. Enter how the purchase price is allocated. The total should add up to your gross sale price above.

Goodwill & Intangibles — brand, customer list, trade name

Taxed at long-term capital gains rates (0%, 15%, or 20%). Usually the largest and most favorably taxed component.

Equipment & Fixtures — machinery, tools, furniture

Depreciation recapture (Section 1245) is taxed as ordinary income up to the amount previously depreciated, then capital gains on anything above.

Real Estate / Building — if included in the sale

Depreciation recapture (Section 1250) is taxed at 25%. Any remaining gain is taxed at long-term capital gains rates.

Inventory

Inventory is taxed as ordinary income — the least favorable treatment. Minimize inventory at time of sale if possible.

Covenant Not to Compete — non-compete agreement value

Also taxed as ordinary income. Buyers often allocate more here for tax deduction purposes — sellers should push back.

Accounts Receivable & Other

Generally taxed as ordinary income.

Total Accumulated Depreciation — on equipment sold

The amount of depreciation you've claimed on equipment over the years. This portion is "recaptured" and taxed as ordinary income (up to 37%) regardless of how the asset is sold.

Step 3 — State & Other Factors

State taxes vary enormously — from 0% to over 13%. Select your state for an accurate combined estimate.

Your State

Self-Employment / Entity Type

Entity type affects whether sale proceeds are subject to self-employment tax and how gains are passed through.

Net Investment Income Tax (NIIT)

The 3.8% NIIT applies to investment income for high earners. If you actively run your business and income exceeds $200K (single) / $250K (joint), consult a CPA — this is a gray area.

Detailed Tax Breakdown

Here is exactly how your estimated tax bill is calculated — line by line.

The 4 types of tax in a business sale

Most sellers are surprised to learn their proceeds are taxed in multiple ways at different rates. Here's what each one means.

Long-Term Capital Gains

0%, 15%, or 20%

Applies to gains on assets held over 1 year — goodwill, intangibles, and appreciated assets. The most favorable tax treatment. Your rate depends on your total income.

Ordinary Income Tax

Up to 37%

Applies to inventory, non-compete agreements, accounts receivable, and short-term gains. Taxed at your regular income tax rate — the least favorable treatment.

Depreciation Recapture

25% (Section 1250) / Up to 37% (Section 1245)

When you sell equipment or real estate for more than its depreciated value, the IRS "recaptures" the depreciation deductions you took. Equipment recapture is taxed as ordinary income; real estate recapture at 25%.

Net Investment Income Tax (NIIT)

3.8%

An additional 3.8% tax on investment income for taxpayers with income over $200K (single) or $250K (joint). May apply to passive business owners. Stacks on top of capital gains tax.

Strategies to reduce your tax bill

These are legitimate, legal strategies that sellers use to keep more of their proceeds. Most require planning well before the sale — ideally 1–2 years out.

Installment sale (seller financing)

Instead of receiving all proceeds in one year, spread payments over multiple years through a seller note. This spreads the taxable gain across multiple tax years, potentially keeping you in lower tax brackets each year.

Potential savings: Significant, especially for sellers near bracket thresholds

Qualified Opportunity Zone (QOZ) investment

Reinvest capital gains into a Qualified Opportunity Fund within 180 days of the sale. Defers and potentially reduces federal capital gains tax. Requires careful planning and qualified investments.

Potential savings: Deferral of federal capital gains tax until 2026 or later

Asset allocation negotiation

Push for more of the purchase price to be allocated to goodwill (capital gains rates) and less to inventory, non-competes, and equipment (ordinary income rates). This is one of the most impactful and immediate strategies.

Potential savings: Tens of thousands of dollars depending on deal size

Charitable Remainder Trust (CRT)

Transfer business interests to a CRT before the sale. The trust sells the business tax-free and pays you income over time. You get a partial charitable deduction and defer capital gains. Complex but powerful for large deals.

Potential savings: Substantial capital gains deferral on large transactions

Move to a no-income-tax state before selling

If you live in a high-tax state (California at 13.3%, New York at 10.9%, New Jersey at 10.75%), relocating to a no-income-tax state (Florida, Texas, Nevada, Wyoming) before the sale can save an enormous amount. Must establish genuine residency — not just a P.O. box.

Potential savings: Up to 13%+ of your total gain

Maximize retirement contributions before closing

In the year of the sale, maximize contributions to SEP-IRA, Solo 401(k), or defined benefit plans. These reduce your ordinary income in the sale year, which may drop you into a lower capital gains bracket.

Potential savings: Varies — depends on plan type and contribution limits

This tool provides rough estimates only and does not constitute tax advice. Tax calculations are highly individual and depend on your complete financial picture, deductions, credits, and applicable state rules. Always work with a qualified CPA or tax attorney before finalizing any business sale.

Federal tax rates based on 2024–2025 IRS guidance. State rates are top marginal rates and may vary based on income level and local taxes.
