Introduction
Sell shares, a rental property, or a batch of crypto, and the IRS may want a report, even if you reinvested every dollar or finished the year at a loss. That catches many Australian investors off guard.
This guide covers U.S. federal Schedule D for tax year 2026. That is not the same as a return filed during calendar 2026, which covers tax year 2025. Only draft 2026 forms were available from the IRS, so check final forms, instructions and line numbers before filing.
You'll learn who files Schedule D, what belongs on it, when Form 8949 is needed, how gains and losses are calculated, and what Australian taxpayers with U.S. obligations should consider.
Key Takeaways
- Schedule D summarises capital gains and losses and passes the net figure to your U.S. return.
- Form 8949 usually lists transactions, but adjustment-free, basis-reported sales can skip it.
- Holding period, basis, wash sales and carryovers can change what you report and owe.
- U.S. and Australian capital gains reporting are separate obligations; one return does not cover the other.
What Is Schedule D for 2026, and Who Must File It?
What Schedule D reports
Schedule D summarises gains and losses from selling or exchanging capital assets. It does not cover wages, interest or regular business income.
A capital asset is almost anything owned for personal use or investment: shares, bonds, funds, a home, collectibles and digital assets. Inventory and depreciable business property are excluded.
Short-term and long-term gains and losses
Holding period decides the category. Short-term means one year or less; long-term means more than one year. Each category is totalled separately, then combined on Schedule D.
For 2026, the IRS published long-term gain rate ceilings in Rev. Proc. 2025-32. They apply to taxable income, not sale proceeds:
| Filing status | 0% up to | 15% up to (20% above) |
|---|---|---|
| Married filing jointly | $98,900 | $613,700 |
| Head of household | $66,200 | $579,600 |
| Single | $49,450 | $545,500 |
| Married filing separately | $49,450 | $306,850 |
Collectibles face a 28% maximum rate, and unrecaptured section 1250 gain a 25% maximum. Net investment income tax of 3.8% can also apply above income thresholds, though nonresident aliens are generally not subject to it.
Who generally files
You generally file Schedule D if you have:
- A sale or exchange of a capital asset
- Capital gain distributions not reported directly on Form 1040
- Capital gains or losses from a Schedule K-1
- A capital-loss carryover from a prior year
When Schedule D may not be required
The 2025 Form 1040 instructions let you skip Schedule D if you have no capital losses and your only gains are 1099-DIV box 2a distributions, with nothing in boxes 2b, 2c or 2d. Check the 2026 instructions when they are released to confirm the same conditions still apply.
Buying and holding is not a reportable event. Losses on personal-use property, such as a car or home furnishings, are not deductible.
Forms, Records, Cost Basis, and Adjustments Needed for Schedule D
Form 8949 and Schedule D together
Form 8949 lists each transaction: description, dates, proceeds, basis, adjustments and gain or loss. Schedule D summarises the totals.
There is an exception. You may aggregate basis-reported 1099-B or 1099-DA transactions that need no adjustments or codes directly on draft 2026 Schedule D lines 1a and 8a. This removes Form 8949, not Schedule D.
The draft 2026 Form 8949 uses boxes A to L:
| Category | Short-term | Long-term |
|---|---|---|
| 1099-B, basis reported | A | D |
| 1099-B, basis not reported | B | E |
| Non-digital, no 1099 | C | F |
| 1099-DA, basis reported | G | J |
| 1099-DA, basis not reported | H | K |
| Digital, no 1099 | I | L |
Documents to gather
- Forms 1099-B, 1099-DA, 1099-S and 1099-DIV
- Schedule K-1 and brokerage statements
- Purchase and sale confirmations
- Last year's Schedule D and carryover worksheet
- For foreign accounts: broker records, exchange rates and withholding statements
Adjusted basis and common complications
Gain or loss is proceeds minus adjusted basis, including permitted costs. Watch for these:
- Wash sales: a loss is disallowed if you buy substantially identical securities within 30 days before or after the sale. The loss generally adds to the replacement basis.
- Inherited property: generally takes date-of-death fair market value.
- Gifted property: when gift-date value is below the donor's basis, use donor basis for gains and the lower value for losses. IRS example: $10,000 basis, $9,000 gift-date value, $9,500 sale yields neither gain nor loss.
- Digital assets: for 2026, brokers report basis only for assets acquired after 2025 and held in the broker's custody until disposal.
Reconciling broker data
Match every 1099 to your own records, especially with multiple brokers, transfers or corrected forms. Fix broker basis errors through adjustments on Form 8949. Missing basis on noncovered securities is your responsibility, so keep evidence for every adjustment.
How to Complete Schedule D for 2026 Step by Step
Line references below come from the 2026 draft and may change. Verify against the final form.
- Classify every transaction. List each sale, note the asset type, split short-term from long-term, and flag those with a 1099-B, 1099-DA or 1099-S.
- Calculate gain or loss. Take proceeds, subtract adjusted basis, apply supported adjustments, and retain the supporting records.
- Complete Form 8949 where required. Enter the description, dates, proceeds, basis, adjustment code and amount, under the correct box.
- Fill Part I (short-term). Lines 1a to 3 take direct and 8949 totals, line 5 K-1 amounts, line 6 carryovers, and line 7 the net.
- Fill Part II (long-term). Lines 8a to 10 take totals, line 12 K-1 amounts, line 13 distributions, line 14 carryovers, and line 15 the net.
- Combine in Part III. Line 16 combines lines 7 and 15. A gain goes to line 7a of Form 1040 or 1040-NR. Line 21 applies the loss limit.
A hypothetical example
These figures are invented for illustration. Suppose you have a $4,000 short-term gain and a $1,500 long-term loss. Netting gives a $2,500 net gain. The draft form then routes that gain to the Qualified Dividends and Capital Gain Tax Worksheet or the Schedule D Tax Worksheet.
Final review checklist
- Every sale is included
- Dates and basis are verified
- Adjustment codes are checked
- All broker forms are reconciled
- Carryovers are included
- Supporting records are retained
How Schedule D Affects Tax and Australian Taxpayers with U.S. Filing Obligations
Gains, losses and carryforwards
Short-term gains are taxed as ordinary income. Eligible long-term gains are taxed at the preferential rates above. Net losses offset gains first, then up to US$3,000 of other income (US$1,500 if married filing separately). Unused losses carry forward until used, keeping their short-term or long-term character.
Australia and U.S. reporting
Schedule D does not replace Australian Taxation Office reporting. Treat them as two computations.
- Residency: a green card or substantial presence makes you a U.S. resident alien (Form 1040). Otherwise Form 1040-NR may apply when required.
- Nonresident share gains: generally exempt below 183 actual U.S. days unless effectively connected (not the weighted substantial presence test). Non-ECI gains go on Schedule NEC, not Schedule D.
- Real property: foreign sellers of U.S. real estate generally face FIRPTA withholding of 15% of the amount realised, reported on Forms 8288 and 8288-A.
- Currency: the U.S. return uses USD at the rate when the item is received, paid or accrued. Australian proceeds convert at the CGT event.
- Double tax: Australian residents declare worldwide gains, and a foreign income tax offset may relieve qualifying U.S. tax.
- Other forms: FBAR or Form 8938 may apply independently.
Outcomes vary with residency, asset location, withholding and entity type. Get fact-specific professional review rather than assuming every U.S. investment needs Schedule D.

Frequently Asked Questions
Who is required to file Schedule D for 2026?
Generally anyone with a sale or exchange of a capital asset, capital gain distributions not reported directly on Form 1040, K-1 capital items, or a loss carryover. Check current IRS exceptions.
What income is reported on Schedule D for 2026?
Capital gains and losses from qualifying sales or exchanges, plus related items such as K-1 amounts and distributions. Wages, interest and routine business income go elsewhere.
Do I need to file both Form 8949 and Schedule D for 2026?
Usually yes. Form 8949 gives transaction detail and Schedule D summarises it. Basis-reported transactions with no adjustments may be entered directly on Schedule D.
When is Schedule D not required for 2026?
When you have no reportable capital transactions, or your only gains are qualifying capital gain distributions reportable directly on Form 1040. Confirm against final instructions.
How do I calculate capital gains and losses for Schedule D?
Subtract adjusted basis from proceeds for each sale. Total short-term and long-term results separately, then net them.
Does an Australian resident need to report U.S. capital gains on both Schedule D and an Australian tax return?
Possibly. U.S. and Australian reporting turn on residency, source, treaty, asset and entity facts. Currency conversion differs, so cross-border advice is wise.
