Schedule D

The Schedule D (Capital Gains and Losses) is the IRS form where you report capital gains and losses from sales of securities, real estate, and other assets. The form is completed after you fill out Form 8949 (detailed transactions) and summarizes your net short-term and net long-term gains or losses. The net result affects your total taxable income and tax liability.

Structure of Schedule D

The form is divided into two parts:

Part I: Short-term capital gains and losses. These are assets held one year or less. Short-term gains are taxed at ordinary income tax rates.

Part II: Long-term capital gains and losses. These are assets held longer than one year. Long-term gains are taxed at preferential rates (0%, 15%, or 20%).

Each part has lines for gains and losses, and a line for the net (gains minus losses).

How to fill out Schedule D

1. Start with Form 8949. List each transaction (sale) with proceeds, cost basis, and gain or loss.
2. Subtotal Form 8949. Sum all short-term and long-term gains and losses.
3. Transfer to Schedule D. Copy the subtotals from Form 8949 to Schedule D.
4. Add 1099-B transactions (if not detailed on Form 8949).
5. Calculate net totals. Sum short-term gains and losses (Part I), then long-term (Part II).

Short-term vs. long-term netting

First, net short-term gains against short-term losses. If you have $50,000 in short-term gains and $30,000 in short-term losses, your net short-term capital gain is $20,000.

Then, net long-term gains against long-term losses. If you have $100,000 in long-term gains and $20,000 in long-term losses, your net long-term capital gain is $80,000.

Netting across holding periods

If you have a net short-term loss and a net long-term gain, they can partially offset. Example:

• Short-term gain: $10,000
• Long-term loss: $30,000
• Net: $20,000 long-term loss

Conversely, if you have a net short-term gain and long-term loss:

• Short-term gain: $50,000
• Long-term loss: $40,000
• Net: $10,000 short-term gain

The character (short-term vs. long-term) of the net determines the tax rate applied.

Capital loss deduction limit

If your net loss exceeds your net gains, you can deduct up to $3,000 of capital losses against ordinary income in a single tax year. Any excess loss is carried forward to future years indefinitely until it is used up.

Example: You have a net $30,000 capital loss. You can deduct $3,000 against wages or other income this year. The remaining $27,000 carries forward to next year.

Carryforward of losses

Capital losses are carried forward to the next tax year (and beyond) until used. You do not need to file a special form; tax software automatically tracks carryforwards. However, you should keep records of loss carryforwards.

Interaction with alternative minimum tax

Large capital losses (and certain deductions) can trigger alternative minimum tax for some high-income investors. If you have large losses, check whether AMT applies.

Distributions from mutual funds

Capital gain distributions from mutual funds (or other pass-through entities) are reported on Schedule D. These are treated as if you sold the underlying securities, and they are long-term capital gains (even if you held the fund for less than one year).

Qualified small business stock and exclusions

If you sold qualified small business stock held over five years, you may be eligible to exclude part of the gain. This is reported on Schedule D with an adjustment.

Depreciation recapture

If you sold real estate or equipment subject to depreciation recapture, the recapture portion is reported on Schedule D (or Form 4797 for business property) and taxed at ordinary rates or the 25% Section 1250 rate.
