Schedule D (Form 1040) – Fillable PDF for 2025

Schedule D (Form 1040) is the IRS worksheet used to report capital gains and losses from the sale of stocks, bonds, real estate, and other investment assets. The 2025 version is now available as a fillable PDF, so you can complete it online without printing.

What Is Schedule D and Who Needs It?

If you sold or exchanged any capital asset during the tax year, you must report the transaction on Schedule D. This includes short‑term gains (held 1 year or less) and long‑term gains (held more than 1 year). Even if you have a net loss, filing Schedule D may allow you to claim a $3,000 deduction against ordinary income.

Common Mistakes & Tips for Accurate Reporting

• Do not mix short‑term and long‑term totals – keep them in separate parts.
• Double‑check the cost basis; an incorrect basis can inflate your tax.
• Remember the $3,000 loss limitation; excess loss carries forward to future years.
• Make sure the totals on Form 8949 match the numbers you enter on Schedule D.
