What Schedule D (Form 1040) 2015 Is For
IRS Schedule D (Form 1040) (2015) is the IRS form used to report capital gains and losses from the sale or exchange of capital assets during the 2015 tax year. A capital asset includes property held for personal use or investment, such as a home, stocks, bonds, mutual funds, or other types of investment property.
Taxpayers use this form to calculate their total gains and losses, separating short-term capital gains from long-term capital gains because each category is taxed differently based on income and the holding period. The form also summarizes totals from Form 8949, which lists individual transactions. Schedule D ensures that all gains, losses, and carryovers from prior years are appropriately reported to determine taxable income and overall tax liability.
When You’d Use Schedule D (Form 1040)
Taxpayers use Schedule D (Form 1040) when they sell or exchange capital assets such as stocks, bonds, real estate, or mutual funds during the tax year. It reports capital gains and losses, including short-term and long-term transactions, as well as capital gain distributions from investments. The form is also required when carrying forward a capital loss from a previous year.
If an error is discovered after filing, such as an incorrect cost basis or an omitted sale, taxpayers must file an amended return using Form 1040-X. The IRS generally allows three years from the original filing date or two years from the date the tax was paid to correct these errors.

Key Rules or Details for 2015
For 2015, taxpayers were required to report most capital asset transactions on Form 8949 before transferring totals to Schedule D. The IRS distinguished between short-term capital gains, taxed at ordinary income rates, and long-term capital gains, which qualified for lower rates. Taxpayers could deduct up to $3,000 ($1,500 if married filing separately) in net capital losses, with any excess carried forward. Additionally, gains from qualified small business stock or home sales may be partially or fully excluded if specific IRS requirements are met.
Step-by-Step (High Level)
Step 1: Gather documentation
Collect all Forms 1099-B from brokers, Forms 1099-S for real estate sales, and records showing cost basis, purchase dates, and sales proceeds. Include any adjustments for commissions, reinvested dividends, or improvements made to the property.
Step 2: Complete Form 8949
List each capital asset transaction on Form 8949. Include the description, acquisition and sale dates, proceeds, cost basis, and adjustments such as wash sales or disallowed losses.
Step 3: Transfer totals to Schedule D
Enter short-term transactions in Part I and long-term transactions in Part II. In Part III, combine totals to determine overall gains or losses.
Step 4: Add additional transactions
Include capital gain distributions from mutual funds and exchange-traded funds, along with any capital loss carryovers from the prior year.
Step 5: Calculate net gain or loss
Combine short-term and long-term results to determine whether there is a net gain or a capital loss. A net loss of up to $3,000 can be offset by other income.
Step 6: Report on Form 1040
Enter the final capital gain or loss on Form 1040, line 13. If qualified dividends or long-term capital gains apply, use the Schedule D worksheet to compute the correct tax rate.

Common Mistakes and How to Avoid Them
Filing Schedule D can be complex, especially when dealing with multiple transactions, stock sales, or mutual fund distributions. Even minor reporting errors can result in processing delays, penalties, or IRS inquiries. Below are the most common mistakes taxpayers make—and how to avoid them.
- Filing after the original due date: Submitting Schedule D late voids the extension and may trigger penalties. File before the due date or request an extension early.
- Confusing an extension to a file with an extension to pay: Form 8868 only extends the filing deadline, not the payment deadline. Taxes must still be paid by the original due date to avoid interest or penalties.
- Using an incorrect cost basis: Taxpayers often miscalculate the cost basis for investments, especially those with reinvested dividends or stock splits. Maintain accurate records and confirm figures with your brokerage statement.
- Overlooking the wash sale rule: The IRS disallows a loss deduction if a stock sold at a loss is repurchased within 30 days before or after the sale. The disallowed loss is added to the cost basis of the new shares.
- Failing to report all capital gain distributions: Many taxpayers overlook reporting capital gain distributions from mutual funds or exchange-traded funds. Verify all distributions on Form 1099-DIV.
Careful recordkeeping, timely filing, and close attention to detail will help ensure Schedule D is accurate and processed smoothly by the IRS.

What Happens After You File
After filing Schedule D (Form 1040), the IRS reviews the information to verify that all reported capital gains and losses match data submitted by brokers and financial institutions. Any discrepancies may result in an IRS notice or a request for clarification. If a net capital gain is reported, it increases taxable income, while a net loss can offset other income up to the allowable limit. Taxpayers should keep supporting documents for at least three years in case the IRS requires verification.
