Schedule D: How to Report Capital Gains and Losses to the IRS

Sold a stock this year? Cashed out crypto? Received a K-1 from a partnership? Then you likely need to file Schedule D — the IRS tax form that tracks what you made (or lost) from capital assets.

For most people, Schedule D sounds intimidating. It doesn’t have to be. This guide explains exactly what Schedule D is, who must file it, how it connects to Form 8949, what tax rates apply to your gains, and when you’re actually off the hook from filing it at all. Whether you’re an individual investor filing your first return with capital gains, or a business managing high-volume transactions across multiple accounts, this is the complete Schedule D reference for 2024 and 2025.

Key Takeaways

What Is Schedule D?

Schedule D is an IRS tax form — formally titled “Capital Gains and Losses” — that you attach to your Form 1040 (your federal tax return). It reports whether you made a profit or a loss when you sold capital assets during the tax year.

Capital assets include:

• Stocks, ETFs, and mutual funds in taxable brokerage accounts
• Bonds and fixed income securities
• Real estate (investment properties, vacation homes, and sometimes your primary residence)
• Cryptocurrency and other digital assets
• Collectibles, art, coins, and precious metals
• Business interests, partnership shares, and S-corporation interests

The IRS wants to know how much you received from selling these assets versus what you originally paid for them. If you made money, you owe tax on the gain. If you lost money, Schedule D helps you use those losses to reduce your tax bill.

What Is Schedule D on a Tax Return? (Form 1040 Schedule D)

Schedule D is one of the supplemental schedules attached to your 1040 form. Here is how they connect:

Who Has to File Schedule D?

You need to file a Schedule D if any of the following apply to your tax year:

• You sold stocks, ETFs, mutual funds, bonds, or other securities through a taxable brokerage account
• You sold real estate that was not your primary residence (rental properties, vacation homes, investment land)
• You sold cryptocurrency or digital assets
• You received capital gains distributions from mutual funds or REITs (in some cases)
• You have capital loss carryforwards from prior tax years that you want to apply
• You received a Schedule K-1 from a partnership, S-corporation, estate, or trust reporting capital gains or losses
• You have installment sale income (Form 6252), like-kind exchange activity, or Section 1256 contracts (Form 6781)
• You are reporting nonbusiness bad debts

When Is Schedule D Not Required?

This is one of the most-searched questions around this form — and both the IRS and many filers overlook the exemptions.

Short-Term vs. Long-Term Capital Gains: The Tax Rate Gap Is Real

The single most important factor on Schedule D is how long you held an asset before selling it. The IRS uses holding period to assign two very different tax rates.

2024–2025 Capital Gains Tax Rates

Holding Period	Classification	Federal Tax Rate
1 year or less	Short-term	Ordinary income rates: 10%–37%
More than 1 year	Long-term	0%, 15%, or 20% (income-dependent)

Short-term gains are taxed at the same rates as your regular wages and salary — up to 37% for high earners in 2024 and 2025. There is no preferential treatment.

Long-term gains receive preferential tax rates. For most taxpayers in 2025, the rate will be 15% on most net capital gains. The 0% rate applies to lower-income filers; the 20% rate applies to the highest earners.

How Schedule D Actually Works: The Three Parts

The Schedule D tax form is two pages and divided into three parts.

Part 1 — Short-Term Capital Gains and Losses

Here you report all transactions where you held the asset one year or less. You enter the totals from your Form 8949 short-term transactions. Part 1 also captures short-term gains or losses from partnerships (K-1s) and wash sale adjustments.

Part 2 — Long-Term Capital Gains and Losses

Same structure as Part 1, but for assets held more than one year. Long-term capital gain distributions from mutual funds and REITs (from Form 1099-DIV) are also entered here.

Part 3 — Summary

Part 3 combines your short-term and long-term results. Lines 16–22 direct you to other worksheets depending on the outcome:

• Net gain: You proceed to the Schedule D Tax Worksheet (or Qualified Dividends and Capital Gain Tax Worksheet) to calculate the actual tax at the correct rate
• Net loss: You may deduct up to $3,000 against ordinary income for the year; any excess carries forward to future years

The final number from Schedule D flows to Form 1040, line 7.

IRS Form 8949 and Schedule D: How They Work Together

Most people who need to file Schedule D will also need to complete Form 8949 (Sales and Other Dispositions of Capital Assets) first. Form 8949 is the detailed transaction-level record. For each sale, you report:

Column	What You Report
(a)	Description of the asset (e.g., “100 shares XYZ Corp”)
(b)	Date acquired
(c)	Date sold
(d)	Sale proceeds
(e)	Cost basis (what you paid, including commissions)
(f)	Applicable codes (wash sale, basis not reported to IRS, etc.)
(g)	Adjustments
(h)	Gain or loss

When Can You Skip Form 8949?

You may be able to bypass Form 8949 and report directly on Schedule D if your broker reported cost basis to the IRS on Form 1099-B and no adjustments are needed (no wash sales, no corrections to basis). But if any adjustment is required — wash sale disallowance, incorrect basis, inherited property — Form 8949 is mandatory.

Form 1099-DIV	Capital gain distributions from mutual funds and REITs	Box 2a amounts reported on Schedule D Part 2, line 13
Form 1099-DA	Digital asset (crypto) broker proceeds — new for 2025 tax year	Source data for Form 8949 and Schedule D
Schedule K-1	Capital gains/losses from partnerships, S-corps, estates, trusts	Passed through to taxpayer and included in Schedule D calculations
Form 4797	Sale of business property	Certain Section 1231 gains/losses may flow into Schedule D

Form 2439	Undistributed capital gains from regulated investment companies	Included in Schedule D Part 2

Crypto and Digital Assets on Schedule D

Cryptocurrency is treated by the IRS as capital property — not currency. Every disposal of a digital asset is a taxable event requiring Schedule D reporting. This includes:

• Selling crypto for cash
• Trading one cryptocurrency for another
• Using crypto to purchase goods or services
• Receiving crypto as payment for work (this is also ordinary income at receipt)

Capital Losses, the $3,000 Deduction, and Carryforwards

Losses on Schedule D are not just accounting entries — they are real tax tools.

How Capital Losses Work

Capital losses offset capital gains dollar-for-dollar. If you made $20,000 in gains and had $8,000 in losses, your net capital gain is $12,000 — and that is what gets taxed. If your losses exceed your gains, the IRS allows you to deduct up to $3,000 of the net loss against ordinary income (wages, salary, self-employment income) for the year.

Capital Loss Carryforward

Any net capital loss beyond $3,000 does not disappear. It carries forward to future tax years, where it can offset future gains or generate another $3,000 ordinary income deduction. Carryforwards continue indefinitely until fully used.

Tax-Loss Harvesting

Tax-loss harvesting is the strategy of deliberately selling investments with unrealized losses before year-end to generate deductible losses that offset realized gains. Done correctly, it can meaningfully reduce your current-year tax bill without permanently exiting a position. The key constraint: the wash sale rule (covered below).

The Wash Sale Rule: What It Is and Why It Matters on Schedule D

The rule: If you sell a security at a loss AND repurchase the same or substantially identical security within 30 days before or after the sale, the loss is disallowed for tax purposes — this is the wash sale rule (IRS Publication 550). The disallowed amount is instead added to the cost basis of the repurchased shares.

On Form 8949, a wash sale adjustment is noted with code “W” in column (f), and the disallowed amount is entered as a positive adjustment in column (g). If you miss it, the IRS will find it.

How to File Schedule D: Step-by-Step

Schedule D Filing Deadlines and Extensions

The 2024 Schedule D (reporting transactions from calendar year 2024) is due with your tax return by April 15, 2025. If April 15 falls on a weekend or federal holiday, the deadline moves to the next business day.

2024 Schedule D: What’s New

For the 2024 tax year (returns filed in spring 2025):

• Capital gains tax rate thresholds have been adjusted for inflation. Most taxpayers continue to pay 0% or 15% on long-term gains
• Crypto reporting is becoming more standardized — brokers are preparing for mandatory 1099-DA issuance for 2025 transactions
• Cost basis reporting rules for covered securities remain in effect; brokers report basis to the IRS for most transactions in taxable accounts

Pennsylvania Schedule D (PA Schedule D)

For Pennsylvania residents: Pennsylvania has its own version of Schedule D called PA Schedule D, which is used to report gains and losses on the PA state income tax return. Key differences from the federal Schedule D:

• Pennsylvania does not recognize capital loss carryforwards the way the federal return does — PA rules limit how losses can offset gains in the same year
• Pennsylvania taxes most capital gains at the flat state income tax rate (currently 3.07%), not at preferential long-term rates
• Certain gains that are tax-free at the federal level (such as gains excluded under the home sale exclusion) may still be taxable for PA purposes

If you are a PA resident with significant investment activity, consult the Pennsylvania Department of Revenue instructions for PA-40 Schedule D, as the rules differ meaningfully from the federal form.

When to Consider Professional Help

Schedule D becomes significantly more complex when your situation includes:

In these situations, errors on Form 8949 and Schedule D can be costly — either in taxes paid unnecessarily or in IRS notices and penalties. A qualified tax professional or CPA with investment reporting experience can ensure accuracy and protect against audit risk. Getting your Schedule D capital gains right the first time is always less expensive than dealing with an IRS notice after the fact.
