What IRS Form 8949 Is For
IRS Form 8949 (2016) is used to report the sale or exchange of capital assets, such as stocks, bonds, mutual funds, or real estate. The form helps the IRS verify your capital gains and losses by listing each transaction with its purchase price, sale amount, and cost basis. It reconciles the details you report with those on Form 1099-B, which your broker sends to you.
Each entry on Form 8949 contributes to Schedule D, where you calculate your total net capital gain or loss and determine how it affects your taxable income and capital gains tax rate for the 2016 tax year.

When You’d Use IRS Form 8949
You’ll need to file IRS Form 8949 (2016) when reporting sales or exchanges of capital assets for the 2016 tax year. The form ensures your capital gains and losses match what your broker reported to the IRS. Below are the most common situations when you would use this form:
- Sale or exchange of investments: You sold or exchanged stocks, mutual funds, bonds, or property that resulted in a capital gain or loss during 2016.
- Broker-reported transactions: You received Form 1099-B showing proceeds from the sale of your investments and must reconcile that information with your tax return.
- Amended return filing: You are using Form 1040X to correct or include investment sales that were missed or misreported on your original return.
- Corrected Cost Basis: You need to adjust the cost basis due to a revised 1099-B, missing data, or prior record-keeping errors.
- Special adjustments: You must report wash sales or other adjustments that affect your capital gains tax calculation.
Filing Form 8949 accurately ensures your reported information aligns with IRS data and helps avoid errors or delays during tax processing.
Key Rules and Details for 2016
When completing IRS Form 8949 (2016), it’s essential to understand how the 2016 rules affect your capital gains and losses. The following key points explain the main requirements:
- Holding period: The time you own an asset determines how it’s taxed. Assets held one year or less create short-term gains, while those held more than a year qualify as long-term capital gains.
- Tax rates: Your capital gains tax rate depends on your income and tax bracket. Long-term gains are usually taxed at lower capital gains tax rates than short-term gains.
- Cost basis methods: Using correct cost basis methods, such as average cost or specific identification, ensures accurate reporting of your gain or loss.
- Capital loss reporting: If you sold an asset for less than you paid, that capital loss can offset gains or carry forward to future years. If capital asset sales were omitted in prior filings, see how to regain compliance through unfiled federal return procedures.
- Wash sales: Losses are not allowed if you buy the same or a similar investment within 30 days, requiring an adjustment on your tax forms.
- Tax loss harvesting: You can use tax loss harvesting to reduce overall gains and lower your capital gains tax.
- State obligations: Most states require you to report investment income and capital gains on your state return and pay any applicable state taxes.
Step-by-Step Guide (High Level)
- Gather records and tax forms: Collect Forms 1099-B, trade confirmations, and investment statements to calculate your capital gains and losses.
- Sort transactions by holding period: Separate sales held one year or less from those held longer to determine whether each sale results in a capital gain or a long-term capital gain.
- Choose cost basis methods: Select from cost basis methods such as specific identification or average cost to ensure accurate calculations.
- Enter each sale on Form 8949: Record purchase and sale dates, proceeds, basis, and note any wash sale adjustments that apply.
- Calculate results: Determine the gain or capital loss for each line, then total by short-term and long-term categories.
- Move totals to Schedule D: Your capital gains tax depends on your tax bracket and the applicable capital gains tax rate; refer to the current capital gains tax rates for guidance.
- Consider planning moves: Use tax loss harvesting strategies when they make sense to help offset gains and reduce your overall tax burden.
- Review and file: Check calculations, attach all required schedules, and submit the return to the IRS.
- Address state requirements: After filing federally, confirm whether you must pay state taxes on your investment income.

Common Mistakes and How to Avoid Them
Filing IRS Form 8949 (2016) correctly helps prevent problems with your tax obligations and future returns. Below are common errors and ways to avoid them:
- Mixing short- and long-term sales: Always separate assets held one year or less from those had more than a year to ensure the correct capital gains rate applies.
- Using the wrong basis: Confirm your adjusted cost basis includes commissions and reinvested dividends to avoid overstating gains and increasing your tax bill.
- Ignoring inherited property rules: For inherited assets, use the fair market value on the original owner’s death date to comply with IRS tax laws.
- Forgetting to offset gains: When capital losses exceed profits, use them to offset capital gains and reduce your income tax.
- Reporting incorrect details: Ensure your filing status, such as married filing jointly, is correct because it affects tax liabilities and itemized deductions.
- Neglecting guidance: Work with a tax advisor or tax professional for complex asset sales or changing tax law.
What Happens After You File
After submitting IRS Form 8949 (2016), the IRS compares your entries to the information reported by brokers. Your tax liability may vary if there are differences in your adjusted cost basis or sale proceeds. When capital losses exceed gains, they can offset capital gains or reduce ordinary income within annual limits.
Any net capital loss carries forward to future years. Your capital gains rate depends on your income, filing status, and the length of time you held each asset—holding an asset for more than a year qualifies for lower rates. To reduce future tax obligations, consult a tax advisor for personalized tax advice.
