Fillable IRS Form 8949 – Capital Gains Tax PDF

When you sell stocks, bonds, real estate, or other capital assets, the IRS requires you to report those transactions on Form 8949. This fillable PDF lets you capture every sale, purchase, and adjustment in a format the IRS accepts.

What Is Form 8949?

Form 8949, Sales and Other Dispositions of Capital Assets, is the primary document for reporting capital gains and losses. The information you provide on this form feeds into Schedule D, which determines your overall capital gain or loss for the tax year.

How to Fill Out the Form Using Formize

Instead of downloading the PDF and opening a separate editor, simply click the "Fill out this form" button on this page. The Formize PDF Filler app will load in your browser, and you can start entering data instantly.

• Enter the description of each asset, dates of acquisition and sale, and the amounts.
• Select the correct type of gain or loss (short‑term, long‑term, or mixed).
• Use the built‑in calculator to apply any adjustments, such as wash‑sale rules.
• When finished, download the completed PDF or export it directly to your tax software.

Common Mistakes to Avoid

• Incorrect dates: Double‑check the acquisition and sale dates; a single‑day error can change the short‑term/long‑term classification.
• Missing basis adjustments: Forgetting commissions, fees, or previous wash‑sale adjustments can inflate your taxable gain.
• Wrong totals: Use the Formize calculator to ensure totals on each page match the summary on Schedule D.
• Incomplete identification: Provide the correct CUSIP or identification number for each security.

Where to Submit Your Completed Form
