How Capital Gains Tax Works

Understanding Capital Gains

Capital gains are the profits realized when you sell an asset for more than its original purchase price. The difference between the selling price and the purchase price (adjusted for expenses) is your capital gain or loss.

Short-term vs. Long-term Capital Gains

Short-term

Assets held for 1 year or less

Taxed at ordinary income rates (10% to 37%)

Long-term

Assets held for more than 1 year

Lower tax rates (0%, 15%, or 20%)

Capital Gains Formula

Capital Gain = Selling Price - (Purchase Price + Expenses)

Where expenses include transaction costs, improvements, and other qualified expenses.

Tax Planning Strategies

Timing Your Sales

Hold assets for at least one year to qualify for lower long-term capital gains tax rates.

Tax-Loss Harvesting

Offset capital gains with capital losses to reduce your overall tax liability.

Home Sale Exclusion

Exclude up to $250,000 ($500,000 for married couples) of capital gains on the sale of your primary residence.

Gifting Appreciated Assets

Consider donating appreciated assets to charity to avoid capital gains tax and potentially receive a tax deduction.

Tax-advantaged Accounts

Invest through retirement accounts like 401(k)s and IRAs where investments can grow tax-deferred or tax-free.

Frequently Asked Questions

What are capital gains?

Capital gains are the profits realized when you sell an asset (like stocks, property, or other investments) for more than what you paid for it. The gain is the difference between the selling price and the purchase price (known as the "cost basis").

How are capital gains taxed differently than regular income?

Long-term capital gains (from assets held for more than one year) are typically taxed at lower rates than ordinary income. Short-term capital gains (from assets held for one year or less) are taxed at the same rates as your regular income.

Do I have to pay capital gains tax on stocks I haven't sold?

No, capital gains tax is only triggered when you sell an asset. Unrealized gains (increases in value on assets you still own) are not taxed until you sell.

What expenses can I include in my cost basis?

You can include expenses directly related to buying, selling, or improving the asset. For stocks, this might include broker commissions. For real estate, this could include closing costs, improvements, and selling expenses.

Are there any exceptions to capital gains taxes?

Yes, several exceptions exist. For example, up to $250,000 ($500,000 for married couples) of capital gains from the sale of a primary residence can be excluded if certain conditions are met. There are also special provisions for small business stock, like-kind exchanges, and inheritances.

How do state capital gains taxes work?

State capital gains tax rules vary widely. Some states have no income tax and therefore no capital gains tax. Others tax capital gains at the same rate as regular income. A few states offer special rates or exemptions for capital gains. Our calculator includes state-specific capital gains tax information.
