How to Report Capital Gains on Your Tax Return With Schedule D

Selling stocks, funds, real estate or other investments can create a taxable gain or deductible loss that must be reported correctly on your federal tax return. Schedule D helps organize those results by separating short- and long-term transactions, combining gains and losses, and determining how much of your investment activity ultimately affects your taxable income.

If you have questions about how capital gains taxes can impact your financial plan, consider reaching out to a financial advisor.

What are Capital Gains and Capital Losses?

A capital gain or capital loss generally occurs when you sell or otherwise dispose of a capital asset, such as stocks, bonds, real estate or other investments. If you sell an asset for more than its adjusted cost basis, you generally have a capital gain. If you sell it for less than its adjusted basis, you generally have a capital loss.

Capital gains and losses are classified as either short-term or long-term based primarily on how long you owned the asset. Assets held for one year or less generally produce short-term gains or losses, while assets held for more than one year generally produce long-term gains or losses. Net short-term gains are generally taxed at ordinary income tax rates, while net long-term gains may qualify for lower capital gains tax rates.

Capital losses can help offset capital gains, which may reduce your taxable income. If your total capital losses exceed your capital gains, individuals can generally deduct up to $3,000 of the excess loss against other income each year, or $1,500 if married filing separately. Losses above the annual limit can generally be carried forward to future tax years.

Not every loss qualifies for a tax deduction. For example, losses from selling personal-use property, such as a personal vehicle or primary residence, generally are not deductible as capital losses. Most taxable sales and exchanges of capital assets are first reported on Form 8949 and then summarized on Schedule D of Form 1040 to calculate the taxpayer’s overall capital gain or loss for the year.

What Is Schedule D?

Schedule D is an IRS tax form used with Form 1040 to report and calculate capital gains and losses from investments and other capital assets. It brings together gains and losses from transactions such as sales of stocks, bonds and other property, along with certain capital gain distributions and capital loss carryovers from previous years.

Many individual transactions are first reported on Form 8949, which lists details such as the asset’s purchase price, sale price and holding period. Those amounts are then transferred to Schedule D, where short-term and long-term gains and losses are totaled separately.

Schedule D is also used to net gains and losses against each other. For example, capital losses can offset capital gains, and if losses exceed gains, taxpayers may generally deduct up to $3,000 of the remaining loss against other income, or $1,500 for married taxpayers filing separately. Excess losses can generally be carried forward to future tax years.

Not every capital transaction has to be listed individually on Schedule D, and certain transactions may be reported directly there without going through Form 8949. The completed Schedule D ultimately helps determine the net capital gain or loss that flows to the taxpayer’s federal income tax return.

How to Report Capital Gains 

For many investment transactions, your broker will send you Form 1099-B showing information such as the sale proceeds and, in many cases, the cost basis. You should compare those figures with your own records before preparing your tax return. Reporting capital gains on your tax return involves the following steps: 

1. Detail each transaction: This process involves recording every sale of assets like stocks, bonds or mutual funds. List the date of purchase, the date of sale, the full purchase price, which is the amount paid to acquire an asset, and the sale price, which can include associated fees or commissions.
2. Total your transactions: This is where you calculate the overall gains and losses from your investments. Using Form 8949, categorize your transactions into short-term (assets held for one year or less) and long-term (assets held for more than one year) assets. Enter the totals from Form 8949 into Schedule D, where you combine all the gains and losses.
3. File your taxes: To complete the process, include Schedule D and Form 8949 with your Form 1040 tax return. Accurate and thorough filing helps in managing your tax liability and ensures compliance with IRS requirements.

Short-Term and Long-Term Capital Gains

Capital gains are either short-term or long-term, depending on how long you’ve held the asset before selling it. Short-term capital gains come from the sale of assets held for one year or less. These gains are taxed at your ordinary income tax rates, which can be as high as 37%, depending on your income bracket. 

Long-term capital gains, on the other hand, come from assets held for more than one year. These gains benefit from lower tax rates, typically 0%, 15% or 20%, based on your taxable income. For example, if your taxable income is up to $47,025 for single filers or $94,050 for married couples filing jointly for tax year 2024, you might qualify for the 0% tax rate on long-term capital gains. The favorable tax treatment of long-term gains is designed to encourage long-term investment.

When you report your gains on IRS Form 8949, you’ll report short-term gains in Part I and long-term gains in Part II. Correct classification and reporting of short-term and long-term gains are vital to accurately determine your tax liability and take advantage of the lower tax rates on long-term investments.

Offsetting Capital Gains With Losses

Capital losses can reduce the amount of capital gains subject to tax. When preparing Schedule D, short-term gains and losses are generally netted against each other first, and long-term gains and losses are netted separately. The resulting short-term and long-term totals are then combined to determine your overall net capital gain or loss for the year.

For example, if you realized a $10,000 capital gain from one investment and a $4,000 capital loss from another, the loss could reduce your net capital gain to $6,000, assuming the transactions are otherwise deductible. This strategy is sometimes called tax-loss harvesting when investors intentionally sell investments at a loss to offset realized gains.

If your total capital losses exceed your capital gains, you may generally deduct up to $3,000 of the remaining net loss against other income, such as wages, or up to $1,500 if married filing separately. Losses that exceed the annual deduction limit can generally be carried forward and used in future tax years until they are exhausted.

There are important restrictions to consider when realizing losses for tax purposes. For example, the wash-sale rule can prevent you from immediately deducting a loss if you buy the same or a substantially identical security within the restricted period surrounding the sale. Losses on personal-use property and certain transactions between related parties may also be nondeductible.

Offsetting gains with losses can lower a tax bill, but investment decisions should not be based on taxes alone. Selling an asset solely to generate a loss could disrupt your portfolio or cause you to miss a later recovery, so tax considerations are generally best weighed alongside your investment goals and long-term strategy.

Bottom Line

Schedule D is used to calculate and report your net capital gains and losses for the year, often using transaction details first reported on Form 8949. Keeping accurate records of purchase prices, sale proceeds and holding periods can help ensure gains and losses are classified correctly. Capital losses may also offset gains and, within annual limits, other income, which can reduce your overall tax liability.
