What Form 1099-B (2016) Is For
Form 1099-B (2016) outlines information related to capital assets that you sell through a brokerage firm during the calendar year. Brokers record proceeds, purchase details, and adjustments that support accurate reporting of capital gains for tax purposes. The form includes entries that reflect amounts reported to the IRS for taxable income calculations.
You use the document to connect each asset to the cost basis method applied to the shares sold. The entries help you determine the gain or loss associated with each transaction. The information guides you as you complete tax forms and apply the figures to your overall tax return.
When You’d Use Form 1099-B (2016)
You receive Form 1099-B when brokers and financial institutions report activity involving a capital asset that you sell during the calendar year. The form includes details about stock sales, exchange-traded funds, and other investments that are linked to your investment strategy. Brokers issue the document to support accurate reporting on income tax filings.
You use the form to match sold shares with the related proceeds and reinvested dividends recorded during the year. The entries help you connect each transaction to the correct tax forms and reflect how the sales affect your overall tax return. The information supports consistent reporting and precise identification of taxable events.
Key Rules or Details for 2016
Many taxpayers review rules for transactions subject to situations where the wash sale rule applies. Brokers may report wash sales when a substantially identical stock is sold and repurchased within the same account, which can result in a disallowed loss for tax reporting purposes. These requirements help you evaluate each transaction with clarity and accuracy.
You can calculate gains or losses using methods linked to the average cost basis or the average cost method for specific holdings. Investors often review the FIFO method when multiple purchase dates affect the treatment of shares sold during the year. These approaches support accurate reporting across different assets.
Additional rules apply when events involve stock splits, the original owner’s death, or accrued market discount. Each of these situations influences the basis assigned to the asset and the potential gain recognized in the filing year. The combined rules help you manage reporting obligations with consistent documentation.

Common Mistakes and How to Avoid Them
Many taxpayers review entries from brokers and must confirm details that affect each capital asset. You can avoid errors when you check reinvested dividends, track basis changes, and apply cost basis methods correctly. The steps help you protect the accuracy of your gain or loss.
- Reinvested dividends: Adding reinvested dividends to the tax basis reduces the risk of errors during the gain calculation.
- Original purchase price: Confirming the original purchase price through statements from the brokerage firm helps prevent inaccurate basis entries.
- Substantially identical stock: Checking for a substantially identical stock or similar security in the same account helps prevent wash sale issues.
- Stock split basis: Updating the per-share cost basis after a stock split helps maintain accurate reporting for each affected share.
- Taxable gain reporting: Calculating gain or loss with the correct basis helps prevent inaccurate taxable gain entries on the return.
These steps strengthen your review of each transaction. They support consistent reporting across all tax forms. They help you reduce filing issues that might affect your taxable income.
What Happens After You File
Many taxpayers want to know how the IRS reviews information after a tax return is filed. The agency matches each entry that brokers reported to the IRS with the figures you enter on the return. These steps help you confirm that all sales and basis amounts appear in the correct sections.
The IRS may issue a CP2000 notice if a difference appears between your entries and the data from the brokerage firm. You may file an amended return when corrected forms or updated details change future capital gains or ordinary income. These steps help you stay confident as you manage reporting across various assets affected by market conditions.
FAQs
How does capital gains tax apply when I sell a capital asset?
Capital gains tax applies when you sell a capital asset for more than your adjusted cost basis. Your tax rate depends on the holding period and whether the gain is classified as a short-term capital gain or a long-term capital gain, which is taxed at a lower rate. You report the net gain on Form 8949 before it is included on your primary tax forms.
How do I calculate adjusted cost basis when different cost basis methods apply?
You calculate the adjusted cost basis by starting with the original purchase price and adding items such as reinvested dividends or fees. Some investments, including mutual funds, allow the use of the average cost basis to simplify calculations. You choose cost basis methods according to IRS rules and apply the same approach for each example in a specific account.
How do stock splits affect calculating cost basis for future reporting?
A stock split changes the number of shares you own and requires you to recalculate the per-share basis. You divide the original basis by the new number of shares to create an accurate adjusted cost basis. You use this updated figure when you determine any future capital gains.
How do I report sales that include interest income or accrued market discount?
You report interest income separately from gains reported on Form 8949. Bonds and similar investments may include accrued market discount, which increases taxable income in the year of sale. You include these amounts to ensure the correct net gain appears on your return.
When do I use Form 8949 to report gains from mutual funds and other investments?
You use Form 8949 when you report gains or losses from mutual funds, stocks, and other capital assets. The form records each sale, the holding period, and adjustments that affect the final amount. You transfer the totals from Form 8949 to Schedule D after you review all entries for accuracy.
