What the Form Is For

Schedule D (Form 1040) is the IRS tax form you use to report profits or losses from selling investments and other valuable property. Think of it as your official record keeper for when you sell stocks, bonds, mutual funds, real estate, cryptocurrency, collectibles, or even your home (in some cases).

When you sell a capital asset—essentially any property you own for personal use or investment—you'll have either a capital gain (you sold it for more than you paid) or a capital loss (you sold it for less than you paid). Schedule D is where you calculate these gains and losses, figure out how much tax you owe on profits, and determine if you can deduct any losses to reduce your overall tax bill.

The form works hand-in-hand with Form 8949 (Sales and Other Dispositions of Capital Assets), which provides the detailed transaction-by-transaction breakdown. Schedule D then summarizes all those transactions and applies the appropriate tax rates based on how long you held the assets. IRS.gov

When You'd Use It (Including Late/Amended Returns)

You must file Schedule D with your annual Form 1040 tax return if you:

• Sold or exchanged stocks, bonds, mutual funds, ETFs, or cryptocurrency during 2024
• Sold real estate (including rental property or a second home)
• Received capital gain distributions from mutual funds or ETFs not reported directly on Form 1040, line 7
• Sold collectibles like artwork, antiques, coins, or precious metals
• Had gains from involuntary conversions (other than casualty or theft) of capital assets not held for business or profit
• Are carrying forward capital losses from previous years
• Received Forms 1099-B from brokers showing investment sales
• Need to report nonbusiness bad debts

Filing Deadlines

• Schedule D must be filed with your 2024 tax return by April 15, 2025 (or October 15, 2025, if you file for an extension)
• If you're filing a late return after the deadline has passed, attach Schedule D to your Form 1040 when you file

Amended Returns

If you discover errors after filing—such as missing transactions, incorrect cost basis, or forgotten sales—you'll need to file Form 1040-X (Amended U.S. Individual Income Tax Return) with a corrected Schedule D and Form 8949. You generally have three years from the original filing deadline to amend your return. IRS.gov

Key Rules for 2024

Short-Term vs. Long-Term Treatment

How long you hold an asset dramatically affects your tax bill:

• Short-term (held 1 year or less): Taxed as ordinary income at your regular tax rate (10%-37% depending on your bracket)
• Long-term (held more than 1 year): Taxed at preferential rates of 0%, 15%, or 20% based on your taxable income

Capital Gains Tax Rates for 2024

According to IRS guidance, for taxable years beginning in 2024, the tax rate on most net capital gain is no higher than 15% for most individuals. However, special rates apply to:

• Collectibles gains: Maximum 28% rate
• Unrecaptured Section 1250 gain (depreciation recapture on real estate): Maximum 25% rate
• Highest earners: Some or all net capital gain may be taxed at 0% or 20% depending on income thresholds and filing status IRS.gov

The $3,000 Loss Limitation

This is one of the most important rules. If your capital losses exceed your capital gains for the year, you can only deduct up to $3,000 of the excess loss against your ordinary income ($1,500 if married filing separately). Any remaining losses must be carried forward to future tax years, where they retain their short-term or long-term character. IRS.gov

Basis Calculation

According to IRS Publication 551, your "basis" is the amount of your investment in property for tax purposes. The basis of property you buy is usually its cost. Use the basis of property to figure depreciation, amortization, depletion, and casualty losses. Calculating correct basis is crucial because it determines your gain or loss. IRS.gov

Nondeductible Losses

You cannot deduct losses from:

• Sales to related parties (family members, controlled entities)
• Wash sales (selling at a loss and repurchasing substantially identical securities within 30 days before or after the sale)
• Personal-use property (like your car or furniture)

Step-by-Step Process (High Level)

Overview

Step-by-step guidance to complete Schedule D for 2024.

Step 1: Gather Your Documents

Collect all Forms 1099-B from brokers, closing statements from property sales, and records showing your purchase price (basis) and purchase dates for everything you sold in 2024.

Step 2: Complete Form 8949 First

Most transactions require detailed reporting on Form 8949 before you can complete Schedule D:

• Report short-term transactions (1 year or less) in Part I
• Report long-term transactions (more than 1 year) in Part II
• List each sale separately with description, dates, proceeds, cost basis, and adjustments
• Check the appropriate box (A, B, C, D, E, or F) based on whether your broker reported basis to the IRS

Step 3: Transfer Totals to Schedule D

Once Form 8949 is complete:

• Transfer short-term totals to Schedule D, Part I (lines 1b, 2, or 3)
• Transfer long-term totals to Schedule D, Part II (lines 8b, 9, or 10)
• Some simple transactions can be reported directly on lines 1a or 8a without Form 8949 if all requirements are met: you received a Form 1099-B that shows basis was reported to the IRS and doesn't show any adjustments in box 1f or 1g; the Ordinary box in box 2 isn't checked; the QOF box in box 3 isn't checked; you aren't electing to defer income due to an investment in a QOF; and you don't need to make any adjustments

Step 4: Calculate Your Net Gain or Loss

Schedule D walks you through combining all your gains and losses:

• Part I calculates your net short-term gain or loss
• Part II calculates your net long-term gain or loss
• Part III combines everything and applies the $3,000 loss limitation if needed

Step 5: Apply the Appropriate Tax Rate

If you have a net capital gain, you'll use either the Qualified Dividends and Capital Gain Tax Worksheet or the Schedule D Tax Worksheet (found in the Form 1040 instructions) to calculate your tax at the preferential rates. IRS.gov

Common Mistakes and How to Avoid Them

Mistake #1: Skipping Form 8949 When Required

Many taxpayers try to report everything directly on Schedule D, but most sales require Form 8949 for detailed transaction reporting. Only aggregate certain transactions on lines 1a/8a if they meet all five specific criteria outlined in the IRS instructions.
Solution: When in doubt, use Form 8949. The IRS instructions emphasize completing Form 8949 before completing lines 1b, 2, 3, 8b, 9, or 10 of Schedule D.

Mistake #2: Misclassifying Holding Periods

Confusing short-term and long-term treatment is common and costly since short-term gains are taxed much higher.
Solution: Count carefully. You must hold an asset for MORE than one year to get long-term treatment. The IRS instructions state that the holding period for long-term capital gains and losses is generally more than 1 year.

Mistake #3: Ignoring Wash Sale Rules

If you sell stock at a loss and buy substantially identical stock within 30 days before or after the sale, the loss is disallowed according to IRS rules.
Solution: Review all purchases around the dates of loss sales. Your broker may identify wash sales on Form 1099-B, but they only track transactions within their own firm—you must track wash sales across all your accounts.

Mistake #4: Exceeding the $3,000 Loss Deduction

Some taxpayers try to deduct all their capital losses against ordinary income, but the IRS strictly limits this to $3,000 ($1,500 if married filing separately).
Solution: Use the Capital Loss Carryover Worksheet in the Schedule D instructions to properly calculate what carries forward to 2025. Keep records of carryovers year after year.

Mistake #5: Incorrect Basis Reporting

Using wrong cost basis leads to incorrect gain/loss calculations and potential IRS scrutiny.
Solution: Keep purchase confirmations, reinvestment records (for mutual funds), and inheritance valuations. IRS Publication 551 provides detailed guidance on determining basis for various types of property acquisitions. Adjust basis for stock splits, dividend reinvestments, and return of capital distributions.

Mistake #6: Not Reporting All Transactions

The IRS receives copies of your 1099-B forms and will notice missing sales.
Solution: Cross-check your return against all 1099-B forms before filing. Report every transaction even if you think it's not taxable. IRS.gov

What Happens After You File

Immediate Results

Your Schedule D results flow to Form 1040, line 7, affecting your total taxable income and tax liability. Net capital gains may qualify for lower tax rates, while the allowed portion of net capital losses reduces your taxable income.

IRS Matching

The IRS automatically matches your reported sales against Forms 1099-B filed by brokers. Discrepancies trigger computer-generated notices proposing additional tax, penalties, and interest. You'll have the opportunity to respond and provide documentation.

Capital Loss Carryovers

If your net capital losses exceed the $3,000 annual deduction limit, the unused losses carry forward indefinitely to future tax years. According to the IRS instructions, if you have a loss and either that loss is more than the loss shown on a later line, or the amount on Form 1040 line 15 would be less than zero, you have a capital loss carryover. These losses retain their character as short-term or long-term. Track carryovers carefully using the Capital Loss Carryover Worksheet in the Schedule D instructions—you'll need these amounts for your 2025 return and beyond. IRS.gov

Record Retention

Keep all supporting documents (purchase confirmations, sale confirmations, Forms 1099-B, adjustment records) for at least three years after filing, though keeping them longer (especially for carryover losses) is advisable. The IRS may require you to substantiate basis and holding periods if your return is examined.

FAQs

Q1: Do I need to file Schedule D if I only have capital gain distributions from mutual funds?

Not necessarily. According to IRS instructions, capital gain distributions can be reported directly on Form 1040, line 7, without filing Schedule D if you have no other capital transactions. However, if you have any sales or want to use losses to offset the distributions, you must file Schedule D.

Q2: Can I deduct losses from selling my personal car or furniture?

No. The IRS defines capital assets but excludes certain property from capital gain or loss treatment. Losses on personal-use property are not deductible. However, if you sell personal property at a gain (like a valuable antique), you must report the gain as a capital gain.

Q3: What's the difference between Schedule D and Form 8949?

Form 8949 is where you report sales and other dispositions of capital assets—listing every individual transaction with full information. Schedule D is the summary form where totals from Form 8949 are transferred and final calculations are performed. The IRS instructions state: "Complete Form 8949 before you complete line 1b, 2, 3, 8b, 9, or 10 of Schedule D." IRS.gov

Q4: I sold cryptocurrency in 2024. How do I report it?

Cryptocurrency is treated as property for tax purposes. Report crypto sales on Form 8949 and Schedule D just like stock sales. Track each purchase (with date and price) and each sale. The IRS Topic 409 on Capital Gains and Losses applies to all capital assets, including virtual currency. Exchanging one cryptocurrency for another is a taxable event.

Q5: What if my broker reports the wrong cost basis on Form 1099-B?

You can (and should) correct it on Form 8949. The IRS instructions explain that you use column (g) to make adjustments with the appropriate adjustment code. Enter the proceeds and basis as reported by the broker in the appropriate columns, then enter your adjustment amount with code "B" (for basis adjustments). Keep documentation proving the correct basis.

Q6: Can I use capital losses to offset ordinary income like wages?

Only up to $3,000 per year ($1,500 if married filing separately). The IRS rules state that capital losses first offset capital gains dollar-for-dollar. Any excess loss above your gains can offset up to $3,000 of ordinary income (wages, interest, etc.). Remaining losses carry forward to future years. IRS.gov

Q7: I inherited stock and sold it this year. How do I determine my holding period and basis?

According to IRS rules, inherited property is generally considered held long-term regardless of how long you actually held it. Your basis is typically the fair market value on the date of the deceased's death (or alternate valuation date if applicable). IRS Publication 551 provides detailed guidance on basis of inherited property. This stepped-up basis often results in little or no taxable gain when beneficiaries sell inherited assets relatively quickly. IRS.gov
