What Form 8858 Is For
U.S. taxpayers use IRS Form 8949 (2010) to report their ownership, income, and transactions related to foreign entities that the U.S. tax system does not recognize as separate for tax purposes. In simple terms, it allows the IRS to monitor business activities conducted abroad through single-owner foreign companies.
Completing this form ensures that foreign earnings, expenses, and transfers are correctly reported and taxed in accordance with U.S. rules. Individuals or businesses with interests in foreign subsidiaries or branches generally must attach Form 8858 to their income tax return each year.
When You’d Use Form 8858
You must file Form 8858 if you are a U.S. person who owns or controls a foreign disregarded entity (FDE) or a foreign branch (FB). This form reports the entity’s income, assets, and transactions so the Internal Revenue Service can determine how foreign business activities affect your overall income tax return.
You are required to file if you directly own an FDE or FB, indirectly own one through another foreign entity, or are a U.S. parent or partner that must consolidate information from controlled foreign corporations or partnerships. Attach Form 8858 to your Form 1040, 1120, or 1065, depending on your filing status. Timely filing helps prevent penalties and ensures accurate international reporting.
Key Rules or Details for 2023
When reporting capital gains and losses for 2023, taxpayers should understand how the IRS classifies and calculates the sale of investments and property. The following rules outline the main points to keep in mind:
- Holding period: Assets held for one year or less result in short-term gains, which are taxed at your ordinary tax rate. Assets held for more than one year qualify as long-term capital gains, which are usually taxed at lower rates.
- Calculating results: The difference between the sales price and the purchase price determines whether you have a net gain or a capital loss. Your cost basis should reflect the amount you originally paid, including any commissions, improvements, or adjustments made to the property.
- Special rules: Inherited property is valued at its fair market value on the date of inheritance. Mutual funds, stocks, and certain assets must be listed on Schedule D using the correct basis. Taxpayers who are married filing jointly should combine their investment income and report sales together.
- Other considerations: All short-term capital gain and long-term capital gain transactions must be reported in the same year in which they occur. Records for personal property or items held for personal use help determine whether the sale is taxable or exempt.
A detailed explanation of the steps to take when the IRS questions capital gain reporting, including documentation to prepare.
Step-by-Step (High Level)
- Gather records for each capital asset transaction, including trade confirms, year-end statements, and closing documents.
- List the capital assets held during 2010 and note the property holding period to classify each sale as short-term or long-term.
- For each sale, compute gain or loss by subtracting your basis from proceeds; include fees in your adjusted basis and note any other basis adjustments shown on statements.
- To facilitate direct reporting on your tax return, enter short-term sales and long-term transactions on the appropriate lines of Schedule D.
- Confirm that the basis shown by the broker matches your records; if it differs, keep documentation and add a brief example worksheet to explain the variance.
- Identify the asset type (stocks, bonds, or real estate) and make sure the correct line is used. For 2010, do not select a marked box for transaction codes, as Form 8949 was not used that year.
- If you are amending a later year where a code applies, or more than one code appears, follow that year’s instructions. For 2010, combine totals and reconcile with income, such as wages, before filing.

Common Mistakes and How to Avoid Them
Several filing errors can cause issues when reporting capital gains and losses, but each has a simple fix.
- Not matching Form 1099-B details: Always compare the totals on your return with the figures listed on Form 1099-B. To avoid discrepancies, review every transaction summary before filing.
- Leaving out short-term transactions: Many taxpayers overlook small trades. Ensure that all short-term transactions are included and are reported in the correct section to prevent IRS mismatches.
- Missing long-term data: Confirm that all long-term transactions reported by your broker are listed on your Schedule D. Double-check before submitting.
- Incorrect reporting format: Each sale must be reported directly on the appropriate line. Avoid selecting a marked box from a later-year form, since Form 8949 was not used in 2010.
- Security and accuracy issues: When filing online, verify the presence of the locked padlock icon before entering financial information. Recheck totals to ensure that money amounts aren’t subject to IRS correction.
What Happens After You File
After you submit your tax return, the Internal Revenue Service reviews all capital gain and loss information. The agency compares what you reported directly on Schedule D with the data from your Form 1099-B and other records. If everything matches, your return moves smoothly through processing.
When differences are identified, you may receive a CP2000 notice requesting clarification or additional documentation. Refunds or balance-due amounts are issued once the necessary adjustments have been made. Keep copies of all forms, worksheets, and brokerage statements for a minimum of three years. Maintaining organized records helps resolve questions quickly and supports accuracy in future filings.
FAQs
What are capital assets, and how do they affect my tax return?
Stocks, bonds, real estate, and other property you own for personal or investment purposes are all examples of capital assets. The sale of these capital assets can create taxable gains or deductible losses that must be reported to the IRS.
How do I calculate a gain or loss on a capital asset?
A gain or loss is the difference between the asset's purchase and sale price. If the gain is from property held for longer than a year, it qualifies as a long-term gain and may be taxed at lower rates. Visit our page explaining the IRS collection process to learn more about how the agency reviews capital gain reporting.

Does my filing status affect how capital gains and losses are taxed?
Your filing status determines which tax rates and deduction limits apply. For example, taxpayers who are married and filing jointly often have higher thresholds before paying tax on capital gains and losses.
