What is Form 1099-B? Broker and Barter Exchange Transactions

IRS Form 1099-B, titled "Proceeds From Broker and Barter Exchange Transactions," reports the sale or exchange of securities and commodities. Brokers must file this form for each customer who:

• Sold stocks, bonds, or other securities through the brokerage
• Received cash, stock, or other property from a corporation during a reorganization
• Transferred stock to a broker in lieu of cash for short sales
• Engaged in barter exchange transactions
• Had regulated futures contracts or forward contracts that were settled

The form reports both the gross proceeds from the sale and, for covered securities, the cost basis of the investment. This information helps taxpayers determine whether they have a capital gain or loss on the transaction.

The following entities are required to file Form 1099-B:

• Brokers: Any person who acts as an agent for another person in selling stocks, securities, commodities, or regulated futures contracts
• Barter Exchanges: Organizations with members or clients who contract with each other to exchange property or services
• Regulated Futures Contracts: Merchants dealing in regulated futures contracts, foreign currency contracts, or Section 1256 options

Note: Brokers must report all covered securities transactions regardless of the amount. There is no $600 threshold like other 1099 forms.

A covered security is one for which the broker is required to report cost basis to the IRS. The rules for what qualifies as a covered security depend on when the security was acquired:

• Stock acquired after January 1, 2011 (except stock in a regulated investment company or dividend reinvestment plan)
• Stock in a mutual fund or dividend reinvestment plan acquired after January 1, 2012
• Certain debt instruments and options acquired after January 1, 2014
• Less complex debt instruments acquired after January 1, 2016

For non-covered securities, the broker reports only the gross proceeds. The taxpayer is responsible for determining and reporting the cost basis.

Form 1099-B contains several key pieces of information:

• Box 1a: Description of property sold (CUSIP number, ticker symbol, number of shares)
• Box 1b: Date acquired
• Box 1c: Date sold or disposed
• Box 1d: Proceeds from the sale (gross amount received)
• Box 1e: Cost or other basis (for covered securities)
• Box 1f: Accrued market discount
• Box 1g: Wash sale loss disallowed
• Box 2: Short-term or long-term gain indicator
• Box 3: Check if basis reported to IRS
• Box 5: Check if noncovered security

The holding period of a security determines whether any gain or loss is classified as short-term or long-term:

• Short-term: Securities held for one year or less. Gains are taxed at ordinary income rates.
• Long-term: Securities held for more than one year. Gains qualify for preferential capital gains tax rates (0%, 15%, or 20% depending on income).

Box 2 on Form 1099-B indicates whether the transaction resulted in a short-term or long-term gain. This classification directly affects how you report the transaction on Form 8949 and Schedule D.

A wash sale occurs when you sell a security at a loss and purchase the same or a substantially identical security within 30 days before or after the sale. The IRS disallows the loss deduction for wash sales.

If a wash sale occurred, Box 1g on Form 1099-B shows the amount of loss that was disallowed. The disallowed loss is added to the cost basis of the replacement shares, which means you can recover the loss when you eventually sell the replacement shares.

When you sell securities, the IRS needs to know your cost basis (what you originally paid) to calculate your gain or loss. Brokers use several methods to determine which shares were sold:

• FIFO (First In, First Out): The default method. Assumes the oldest shares purchased are sold first. This often results in higher long-term gains since older shares have had more time to appreciate.
• Specific Identification: You choose exactly which shares to sell. This gives you the most control over your tax outcome but requires careful record-keeping.
• Average Cost: Used primarily for mutual funds. Your cost basis is the average price of all shares you own. Once you use this method for a fund, you must continue using it for that fund.
• LIFO (Last In, First Out): Assumes the most recently purchased shares are sold first. This can minimize gains in a rising market.

Your broker reports the cost basis method used in Box 1e. If you want to use a specific method other than FIFO, you must instruct your broker before the sale.

Form 1099-B provides the data you need to complete Form 8949 and Schedule D. Here is the typical process:

1. Review your 1099-B: Check that the proceeds, cost basis, and holding periods match your records.
2. Separate transactions by type: Group short-term covered, short-term noncovered, long-term covered, and long-term noncovered transactions.
3. Complete Form 8949: Report each transaction with date acquired, date sold, proceeds, cost basis, and gain or loss. Use Part I for short-term and Part II for long-term.
4. Transfer totals to Schedule D: Summarize your Form 8949 totals on Schedule D, which calculates your net capital gain or loss.
5. Apply the $3,000 capital loss limit: If you have a net capital loss, you can deduct up to $3,000 against ordinary income. Excess losses carry forward to future years.

If the cost basis reported on your 1099-B matches what your broker reported to the IRS and no adjustments are needed, you may be able to report summary totals directly on Schedule D without filing Form 8949.

Several corporate actions and special situations can complicate 1099-B reporting:

• Stock Splits: Your cost basis per share adjusts to reflect the split. A 2-for-1 split cuts your per-share basis in half while doubling your shares.
• Mergers and Acquisitions: When a company you own is acquired, you may receive cash, stock in the acquiring company, or both. Each scenario has different tax implications.
• Spin-offs: When a company distributes shares of a subsidiary, your original cost basis is allocated between the parent and the new company.
• Return of Capital: Distributions that exceed earnings reduce your cost basis rather than creating taxable income. This affects your eventual gain or loss when you sell.
• Inherited Securities: Securities received through inheritance typically get a stepped-up basis equal to the fair market value on the date of death.
• Gifted Securities: The cost basis for gifted securities depends on whether you sell at a gain or loss. Your basis may be the donor's original basis or the fair market value at the time of the gift.

Brokers may not have complete information for these situations, especially for noncovered securities or inherited assets. Always verify the reported basis against your own records.

Brokers must meet the following deadlines for Form 1099-B:

• Recipient Copy: February 15th (since Form 1099-B reports securities transactions, it has an extended recipient deadline compared to most 1099 forms)
• IRS Filing (Paper): February 28th
• IRS Filing (Electronic): March 31st

When a deadline falls on a weekend or federal holiday, the due date moves to the next business day. For specific dates for the current tax year, see our Form 1099-B Filing Deadlines.

If you need additional time to file, you can request a 30-day extension using Form 8809.

When filing or reporting Form 1099-B information, watch out for these common errors:

• Incorrect cost basis: Verify that the reported cost basis matches your records, especially for securities acquired through multiple purchases.
• Missing wash sale adjustments: If you repurchased a security within 30 days, make sure the wash sale rules are properly applied.
• Wrong holding period: Short-term gains are taxed at higher rates than long-term gains. Verify the holding period classification.
• Duplicate reporting: If you have multiple brokerage accounts, each broker reports separately. Do not double-count transactions on your tax return.
• Ignoring noncovered securities: For noncovered securities (Box 5 checked), you must calculate and report your own cost basis.
