What is Schedule D (Form 1040)?

Schedule D (Form 1040) is the IRS schedule used to report capital gains and losses for the year and figure the overall net gain or loss. It attaches to your Form 1040 (or 1040-SR/1040-NR) and is not filed on its own. Part I covers short-term transactions (assets held one year or less) and Part II covers long-term transactions (held more than one year), with most line detail coming from Form 8949. Part III nets everything together: the result on Line 16 carries to Form 1040, capital gain distributions and any capital-loss carryover are folded in, and net losses are limited to $3,000 ($1,500 if married filing separately) per year. JustFill makes Schedule D fillable in your browser so you can type or dictate your figures and download the completed PDF free.

Who fills out Schedule D (Form 1040)?

  • Investors who sold stocks, bonds, ETFs, or mutual funds during the tax year
  • Cryptocurrency holders who sold, swapped, or otherwise disposed of digital assets
  • Homeowners or property owners who sold real estate or other capital assets at a gain or loss
  • Taxpayers who received capital gain distributions from mutual funds or REITs (often via Form 1099-DIV)
  • Anyone carrying a prior-year capital loss forward into the current return

Field-by-field breakdown

What each section of Schedule D (Form 1040) asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.

Part I — Short-Term (Lines 1a–7)

Net short-term gains and losses from assets held one year or less, with totals pulled from Form 8949 boxes A, B, and C, plus any short-term carryover on Line 6.

Part II — Long-Term (Lines 8a–15)

Net long-term gains and losses from assets held more than one year, totals from Form 8949 boxes D, E, and F, plus capital gain distributions (Line 13) and long-term carryover (Line 14).

Form 8949 totals (proceeds, basis, gain)

For each box, you enter aggregate proceeds (d), cost basis (e), adjustments (g), and the resulting gain or loss (h) that carry from Form 8949.

Line 16 — Net gain or loss

Combines Part I and Part II; this overall figure is what carries to Form 1040, line 7.

Part III — Summary (Lines 17–20)

Checkboxes and prompts directing you to the 28% Rate Gain Worksheet and Unrecaptured Section 1250 Gain Worksheet when collectibles or certain real estate gains apply.

Line 21 — Capital loss limit

Caps a deductible net capital loss at $3,000 ($1,500 if married filing separately); any excess carries forward to next year.

Line 22 — Qualified dividends

Prompts whether to use the Qualified Dividends and Capital Gain Tax Worksheet or the Schedule D Tax Worksheet to figure the tax.

Common mistakes to avoid

  • 1Entering individual trades directly on Schedule D — most detail belongs on Form 8949 first, and only the column totals carry to Schedule D.
  • 2Putting a transaction in the wrong part — short-term (held one year or less) goes in Part I and long-term (held more than a year) in Part II, and the holding period changes the tax rate.
  • 3Forgetting the annual loss limit — a net capital loss is capped at $3,000 ($1,500 if married filing separately), with the rest carried forward, not deducted all at once.

Frequently asked questions

Usually yes. Most individual sales are listed on Form 8949 first, and the column totals (proceeds, cost basis, and gain or loss) carry to Schedule D. Some taxpayers whose 1099-B amounts need no adjustment can report certain totals directly on Schedule D, but most use Form 8949 for the detail.
