Schedule D (Form 1040) is where those results are totalled and carried to your return. Form 8949, your brokerage statements, holding periods and loss carryovers all feed into it.
This guide covers U.S. federal reporting using the 2025 forms. Rate thresholds below are for 2026. Check the latest IRS forms and instructions before filing, especially if your situation is complex or involves foreign assets.
Key Takeaways
- Schedule D summarises gains and losses; Form 8949 usually supplies the transaction-level detail.
- Adjusted basis, proceeds, dates and holding period decide the amount and the tax treatment.
- Fund distributions, digital assets, inherited property, wash sales, K-1s and old losses can all change the result.
- Current IRS instructions override this guide if forms or thresholds change.
What Is Schedule D and Who May Need to File It?
What does Schedule D report?
Schedule D combines gains and losses from selling or exchanging capital assets. Typical examples are stocks, bonds, mutual funds, digital assets, investment property and certain collectibles. Under IRC 1221, a capital asset is property you hold, minus statutory exclusions such as inventory and depreciable business property.
Wages, interest, ordinary dividends and business inventory are reported elsewhere. Some transactions start on other forms (such as Form 4797) before any amount reaches Schedule D. The 2025 Schedule D result flows to Form 1040 line 7a.
Who may need it?
You will likely need Schedule D if you have any of the following:
- Sales of stocks, bonds, funds or digital assets
- Capital gain distributions that cannot be reported directly on Form 1040
- A capital loss carryover from a prior year
- Capital gain or loss on a partnership or trust Schedule K-1
- Capital amounts from Forms 6252, 4684, 6781 or 8824
There is a narrow exception. If your only capital item is a Form 1099-DIV box 2a distribution (with no amounts in boxes 2b, 2c or 2d), you may report it directly on line 7a instead.
Nonresidents and foreign assets
Form 1040-NR filers follow different capital gains rules. Under IRS Publication 519, non-effectively-connected U.S.-source capital gains of nonresident aliens are generally taxed at 30% (or a lower treaty rate) if the person was in the U.S. 183 or more days.
Those gains go on Schedule NEC. Effectively connected gains may use Schedule D or Form 4797.
U.S. persons with foreign accounts may also owe FBAR (aggregate foreign accounts over $10,000) and Form 8938 filings, which are separate from Schedule D.
Personal-use losses
Gains on personal-use property, such as your car or furnishings, are taxable. Losses on that property generally are not deductible. Losses on investment property may still be reported on Schedule D.
How Form 8949, Brokerage Forms and Schedule D Work Together
Start with the source documents
Gather these before you calculate anything:
- Form 1099-B (securities) and Form 1099-DA (digital assets)
- Form 1099-DIV, especially box 2a
- Schedule K-1 forms
- Last year's Schedule D and any loss carryover worksheet
- Purchase confirmations and closing statements
Brokers often report proceeds and basis. Reconcile them against your own records, because basis can be missing, wrong or in need of adjustment.
Calculate gain or loss per transaction
The formula is simple: amount realised minus adjusted basis, with selling costs reducing the amount realised. Cash received is not the gain.
Basis starts with the purchase price plus acquisition costs such as commissions and transfer fees. Adjust it only where relevant, for example for reinvested distributions, splits, depreciation, or gift and inheritance rules.
Special basis rules:
- Inherited property (IRC 1014): generally date-of-death fair market value, and treated as long-term regardless of how long it was actually held.
- Gifted property (IRC 1015): the donor's basis for gains, the lower gift-date value for losses. A sale between the two figures produces neither gain nor loss.
Classify as short-term or long-term
Held one year or less is short-term. Held more than one year is long-term. Check acquisition and sale dates carefully. Gifted and inherited assets have their own holding-period rules.
Decide whether Form 8949 is required
Form 8949 lists individual sales when basis, reporting status or adjustments need disclosure. Each transaction goes in a box based on how it was reported:
| Reporting status | Standard assets (short / long) | Digital assets (short / long) |
|---|---|---|
| Basis reported to IRS | A / D | G / J |
| Basis not reported to IRS | B / E | H / K |
| No 1099-B or 1099-DA | C / F | I / L |
You may skip Form 8949 and enter totals directly on Schedule D lines 1a and 8a only if all of these apply:
- Basis was reported to the IRS
- No adjustments or codes are needed
- The asset is not a collectible
- No qualified opportunity fund deferral applies
Broker basis reporting phased in by acquisition date:
- Stocks: from 2011
- Mutual funds and dividend reinvestment plans: generally from 2012
- Certain debt and options: from 2014 and 2016
For digital assets, 2025 sales require proceeds reporting. Mandatory basis reporting starts with 2026 sales of covered assets acquired after 2025 in a custodial account.
If the broker's basis is wrong, the IRS instructions say to leave the broker's figure in column (e), enter code B, and correct it in column (g).
In the IRS example, stock sold for $1,000 has a true basis of $100 but the broker reports $900. You enter $1,000 / $900 / code B / +$800 adjustment, and report a $900 gain.
Transfer the results
Form 8949 totals flow to Schedule D, and Schedule D's final result goes to Form 1040. Here is a hypothetical illustration, not a personal tax estimate:
| Sale | Held | Proceeds | Basis | Result |
|---|---|---|---|---|
| A | 8 months | $5,000 | $4,200 | +$800 short-term |
| B | 3 years | $12,000 | $9,000 | +$3,000 long-term |
| C | 5 months | $2,500 | $3,100 | −$600 short-term |
Short-term nets to $200, long-term is $3,000, so line 16 shows a $3,200 net gain. Cash received was $19,500, yet only $3,200 is the gain.
How to Complete Schedule D
Part I: short-term gains and losses
- Line 1a: totals entered directly (no Form 8949 needed)
- Lines 1b, 2 and 3: Form 8949 totals for boxes A/G, B/H and C/I
- Line 4: short-term gain from Form 6252, plus capital amounts from Forms 4684, 6781 and 8824
- Line 5: net short-term amounts from K-1s
- Line 6: short-term loss carryover
- Line 7: net short-term total
Part II: long-term gains and losses
- Line 8a: totals entered directly
- Lines 8b, 9 and 10: Form 8949 totals for boxes D/J, E/K and F/L
- Line 11: Form 4797 Part I gain, Forms 2439 and 6252 gains, and capital amounts from Forms 4684, 6781 and 8824
- Line 12: net long-term amounts from K-1s
- Line 13: capital gain distributions
- Line 14: long-term loss carryover
- Line 15: net long-term total
These line references reflect the 2025 form. Confirm them against the 2025 Schedule D instructions for your filing year.
Part III: net the results
Line 16 combines lines 7 and 15. A gain goes to Form 1040 line 7a.
If both lines 15 and 16 are gains, complete the rate worksheets:
- 28% Rate Gain Worksheet (line 18)
- Unrecaptured Section 1250 Gain Worksheet (line 19)
For the tax computation, line 20 sends most filers to the Qualified Dividends and Capital Gain Tax Worksheet. Otherwise use the Schedule D Tax Worksheet.
A net loss on line 21 is capped at the smaller of the loss or $3,000 ($1,500 if married filing separately).
Summary versus detail
You can use a summary when basis was reported to the IRS, the transactions are covered, and no wash sale, corrected basis, or other adjustment applies. With multiple brokerage accounts, confirm that each one qualifies. You may still list transactions on Form 8949 even when a summary is allowed.
Final review before filing
- Reconcile Form 8949 totals to brokerage statements.
- Confirm each sale is in the right short- or long-term category.
- Verify prior-year carryovers.
- Make sure Schedule D's result reaches Form 1040 only once.
How Capital Gains, Losses and Special Transactions Affect Tax Reporting
Short-term versus long-term rates
Short-term gains are taxed at ordinary rates. Long-term gains get preferential rates based on taxable income. Per Rev. Proc. 2025-32, the 2026 long-term bands are:
| Filing status | 0% through | 15% through | 20% above |
|---|---|---|---|
| Single | $49,450 | $545,500 | $545,500 |
| Married filing jointly | $98,900 | $613,700 | $613,700 |
| Married filing separately | $49,450 | $306,850 | $306,850 |
| Head of household | $66,200 | $579,600 | $579,600 |
Special rates apply to collectibles (28%) and unrecaptured section 1250 gain (25%).
The 3.8% net investment income tax applies to the lesser of net investment income or MAGI over $200,000 (single or head of household), $250,000 (joint) or $125,000 (separate). Report it on Form 8960.
Losses, carryovers and wash sales
Losses first offset gains. Any excess is deductible up to $3,000 a year against other income. The remainder carries forward indefinitely and keeps its short- or long-term character. Use the Capital Loss Carryover Worksheet in the Schedule D instructions.
A wash sale (IRC 1091) occurs when you sell stock at a loss and buy a substantially identical replacement within 30 days before or after. The rule applies across accounts, and purchases by your spouse or in an IRA or Roth IRA can trigger it.
The disallowed loss normally increases the replacement's basis, except for IRA and Roth IRA purchases. One broker's statement will not show activity at another broker.
Capital gain distributions
Mutual funds and REITs can distribute gains even if you never sold a share. These appear in Form 1099-DIV box 2a and are long-term regardless of how long you held the fund. Reinvesting does not remove the reporting. Treat them separately from ordinary and qualified dividends.
Digital assets, real estate and business property
Selling, exchanging or spending digital assets creates a reportable disposition. Since January 1, 2025, basis must be tracked per wallet or account using specific identification or FIFO. Rev. Proc. 2024-28 offers a transition safe harbour for allocating unused basis.
Other transactions start on different forms:
- Business property: Form 4797
- Installment sales: Form 6252 (not available for publicly traded securities)
- Casualty and theft: Form 4684
- Like-kind exchanges: Form 8824 (real property only since 2018)
- Home sales: up to $250,000 ($500,000 joint) may be excluded, but a Form 1099-S or any taxable gain must be reported on Form 8949 and Schedule D
Inherited, gifted and foreign-related assets
Keep estate valuations, appraisals, transfer documents and donor basis records. They determine basis and holding period.
For foreign accounts or nonresident status, Schedule D may be one piece of the filing. FBAR, Form 8938 (for example, $50,000 at year-end for a single filer living in the U.S.), PFIC Form 8621 and treaty relief may apply.
Common Schedule D Errors and Records to Prepare
Documents and reconciliation checklist
Keep these on file:
- Brokerage statements, 1099-B, 1099-DA and 1099-DIV forms
- Digital-asset transaction histories
- Purchase confirmations and basis records
- Prior returns and carryover worksheets
- K-1s and property closing documents
- Inheritance or gift paperwork
Retain most records for 3 years. Keep property and basis records until the limitation period ends for the year you dispose of the asset. Worthless-security claims generally call for 7 years. Never assume an imported broker summary is complete.
Frequent mistakes
- Reporting gross proceeds as the gain
- Omitting basis
- Double-counting summarised transactions
- Misclassifying holding periods
- Missing capital gain distributions
- Losing prior-year carryovers
- Ignoring wash-sale adjustments
- Deducting personal-use losses
- Putting every capital transaction directly on Schedule D without checking the relevant form
Mismatches can trigger an IRS CP2000 notice. It proposes changes and is not a bill.
When professional support helps
Consider help if you deal with any of the following:
- Multiple brokerage accounts
- Missing or corrected basis
- Digital assets
- Inherited or gifted property
- Business sales, foreign investments or K-1s
- Large gains or losses, or an IRS notice

Frequently Asked Questions
How do I report capital gains and losses on a tax return?
Start with broker or transaction records, list sales on Form 8949 when required, total them on Schedule D, then carry the result to Form 1040 line 7a. Some eligible covered transactions can be summarised directly on Schedule D.
When should I use Schedule D or Form 8949?
Schedule D summarises and nets your gains and losses. Form 8949 lists and reconciles individual transactions. Basis reporting and adjustments determine whether Form 8949 is needed.
Do I need to report capital gain distributions?
Yes. Form 1099-DIV box 2a distributions are reportable even if you sold no fund shares. They generally flow to Schedule D line 13, or directly to Form 1040 if you meet the distribution-only exception.
How do I calculate capital gains?
Subtract adjusted basis from the amount realised, after reducing proceeds for selling costs. The result is rarely the same as the cash you received.
Can I deduct capital losses from capital gains?
Yes. Losses offset gains first. Any net loss beyond that is deductible up to $3,000 a year ($1,500 if married filing separately), with the balance carried forward.
What is considered a capital asset according to the IRS?
Under IRC 1221, it is property you hold, such as stocks, bonds, funds, digital assets, your home and personal vehicle. Inventory and depreciable business property are excluded and follow other rules.
