Capital Gains Tax Explained for Business Sales

When you sell your business, the IRS wants a piece of your profit. Capital gains tax is one of the biggest expenses you'll face during a business sale, and understanding how it works can save you serious money.

Below is a clear breakdown of what you need to know about capital gains tax for business sales – without the tax jargon that makes your head spin.

What Is Capital Gains Tax?

Capital gains tax is the tax you pay on the profit from selling your business. It's not based on how much you sell for – it's based on how much more you sell for than what you originally put into the business.

Here's the basic math: Capital Gain = Sale Price - Your Basis

Your "basis" is essentially what you've invested in the business over the years. This includes your original purchase price (or startup costs), plus any improvements you made, minus any depreciation you've claimed on your taxes.

For example, if you sell your business for $500,000 and your basis is $200,000, you'd have a capital gain of $300,000 that's subject to capital gains tax. Basis is one of the most important inputs in determining fair market value at exit.

How Capital Gains Tax Rates Work

The good news? Capital gains tax rates are generally lower than regular income tax rates. The IRS gives preferential treatment to capital gains because they want to encourage investment and business ownership.

For 2025, long-term capital gains tax rates are:

• 0% for lower-income taxpayers

• 15% for most middle-income taxpayers

• 20% for high-income taxpayers

But here's where it gets tricky – these rates can effectively be higher when you factor in additional taxes like the Net Investment Income Tax, which adds 3.8% for high earners.

Long-Term vs. Short-Term Capital Gains

The length of time you've owned your business makes a huge difference in your tax bill.

Long-Term Capital Gains apply if you've owned your business for more than 12 months. These get the preferential rates we just mentioned (0%, 15%, or 20%).

Short-Term Capital Gains apply if you've owned the business for 12 months or less. These are taxed as ordinary income, which means they could be taxed at rates up to 37% – potentially doubling your tax bill compared to long-term rates.

The message is clear: if you're thinking about selling, holding onto your business for at least a year can save you a fortune in taxes.

Business Assets Aren't All Treated the Same

When you sell a business, you're not just selling one thing – you're selling multiple assets. The IRS treats different types of business assets differently for tax purposes.

Capital Assets (like equipment, real estate, goodwill) typically qualify for capital gains treatment. This is what you want.

Ordinary Income Assets (like inventory, accounts receivable) are taxed at regular income rates, which are higher.

The allocation of your sale price among these different assets becomes crucial. You and the buyer need to agree on how to split up the total purchase price, and this allocation directly affects your taxes. Buyers often negotiate allocations based on the value drivers they care about most.

As the seller, you generally want to allocate as much as possible to capital assets rather than ordinary income items. But the buyer often prefers the opposite because they get better tax deductions.

Calculating Your Basis

Getting your basis calculation right is critical because it determines how much of your sale proceeds are taxable. Your basis includes:

What Increases Your Basis:

• Original purchase price or startup costs

• Capital improvements and equipment purchases

• Additional money you've invested over the years

What Decreases Your Basis:

• Depreciation you've claimed on equipment and buildings

• Any casualty losses you've deducted

• Previous distributions that exceeded your basis

Many business owners are surprised to learn that depreciation they claimed over the years reduces their basis, potentially increasing their capital gains tax bill when they sell.

Depreciation Recapture: The Hidden Tax

Here's something many business owners don't see coming: depreciation recapture.

If you've claimed depreciation on business assets over the years, the IRS requires you to "recapture" some of that depreciation when you sell. This recaptured depreciation is taxed at ordinary income rates (up to 25% for most assets), not the lower capital gains rates.

For example, if you claimed $50,000 in depreciation on equipment over the years, you might need to pay ordinary income tax rates on that $50,000 when you sell, even if the rest of your gain qualifies for capital gains treatment.

State Taxes Matter Too

Don't forget about state taxes. While we've been focusing on federal capital gains taxes, most states also impose their own capital gains taxes.

Some states like Florida, Texas, and Nevada have no state income tax, so you'd only pay federal capital gains tax. But states like California can add another 13%+ to your tax bill.

If you're planning a business sale, your state of residence at the time of sale can significantly impact your total tax burden.

Planning Strategies to Reduce Your Tax Bill

Timing the Sale If you've owned your business for less than a year, waiting to hit the 12-month mark can cut your tax rate in half.

Installment Sales Instead of receiving all your money upfront, you can structure the sale to receive payments over several years. This can help keep you in lower tax brackets and potentially reduce your overall tax rate.

Asset Allocation Negotiation Work with the buyer to allocate as much of the purchase price as possible to capital assets rather than ordinary income items.

Consider Your Other Income The timing of your sale matters. If you have a high-income year from other sources, you might want to delay the sale to a year when your other income is lower.

Common Scenarios and Examples

Let's look at a real example. Say you started a business 10 years ago with $100,000, invested another $50,000 in equipment over the years, and claimed $30,000 in depreciation.

Your basis would be: $100,000 + $50,000 - $30,000 = $120,000

If you sell for $600,000, your capital gain is $480,000. You'd also need to recapture that $30,000 in depreciation at ordinary income rates.

At a 15% capital gains rate, you'd pay $72,000 on the capital gain, plus ordinary income tax on the $30,000 recapture – potentially another $7,500 to $11,100 depending on your tax bracket.

Getting Professional Help

Capital gains tax calculations can get complicated quickly, especially with business sales involving multiple assets, depreciation recapture, and various tax planning opportunities.

The stakes are high – we're often talking about tens or hundreds of thousands of dollars in taxes. Small mistakes in basis calculations or asset allocations can cost you big money.

Most business owners benefit from working with both a qualified accountant and a business broker who understands the tax implications of different deal structures.

The Bottom Line in Capital Gains Tax for Business Sales

Capital gains tax will likely be one of your largest expenses when selling your business, but understanding how it works puts you in control. The difference between long-term and short-term rates alone can save you enormous amounts of money.

The key is planning ahead. Don't wait until you're ready to sell to start thinking about the tax implications. The decisions you make today about timing, structure, and planning can significantly impact how much money you actually walk away with when you sell your business.

Early tax planning is a core part of sale readiness, not a last-minute decision.

Remember, the goal isn't just to sell your business – it's to maximize what you keep after taxes. Understanding capital gains tax is a crucial part of that equation.
