No, you cannot file a 1099-B on your own bank deposits

A 1099-B is a form that brokers and financial institutions file with the IRS to report the sale of securities — stocks, bonds, mutual funds, cryptocurrency on an exchange. It documents what you sold, when you sold it, and the proceeds. Your bank does not issue this form for ordinary deposits, transfers, or account activity.

If you received a 1099-B in the mail, it came from a brokerage account, not your checking or savings account. If you're wondering whether your bank deposits should generate a 1099-B, the answer depends on what those deposits actually are. Paycheck deposits, transfers from other accounts, and gifts do not trigger a 1099-B. Sales of investments do.

The confusion usually arises because banks and brokerages sometimes operate under the same roof, and the forms look similar. But they track different things. Your bank statement shows money moving in and out. A 1099-B shows the tax consequences of selling something you owned.

Key Takeaways

  • A 1099-B reports the sale of securities and comes from a brokerage, not from your bank's deposit accounts.
  • Regular bank deposits — paychecks, transfers, gifts — do not generate a 1099-B under any circumstance.
  • If you sold stocks, bonds, or cryptocurrency through a brokerage account, that brokerage files the 1099-B, not you.
  • The IRS receives a copy of every 1099-B filed, so misreporting or omitting one creates a mismatch the agency will catch.
  • If you received a 1099-B you believe is wrong, contact the brokerage that issued it to request a corrected form.

What a 1099-B actually reports

A 1099-B documents the sale of a security — meaning you bought something, held it, and sold it for a price. The form shows the sale date, the proceeds (what you received), and sometimes the cost basis (what you paid). The brokerage that executed the sale files this form with the IRS and sends you a copy by January 31st of the following year.

This applies to stocks, bonds, mutual funds, exchange-traded funds (ETFs), and cryptocurrency sold through a regulated exchange or brokerage. It does not explore to real estate, vehicles, or personal property. It does not explore to money sitting in your bank account, no matter how much or where it came from.

The 1099-B exists because the IRS wants to know about capital gains — the profit you made when you sold something for more than you paid for it. Your bank has no way of knowing whether a deposit represents income, a gift, a loan repayment, or a transfer from another account you own. So it does not file a 1099-B for deposits.

Why you might have received a 1099-B you don't recognize

If a 1099-B arrived in your name but you don't remember selling any investments, one of three things happened: you have a brokerage account you forgot about, someone opened an account in your name without permission, or the form was sent to the wrong address and belongs to someone else.

The first scenario is common. Many people open brokerage accounts years ago through an employer retirement plan, a one-time investment, or a robo-advisor, then stop paying attention. If the account was active and a sale occurred, the 1099-B will arrive even if you haven't logged in since 2015.

The second scenario — identity theft or fraud — is less common but serious. If you do not recognize the brokerage or the account, contact them when ready with your ID and ask for account details. If you never opened the account, file a fraud report with the FTC at IdentityTheft.gov and notify the brokerage in writing.

The third scenario happens occasionally with mail forwarding errors or data entry mistakes. Check the account number and brokerage name on the form. If neither matches anything you own, contact the brokerage to confirm the address is wrong, then ask them to correct their records.

How to report a 1099-B on your tax return

You do not file the 1099-B itself. Instead, you report the information from the 1099-B on your tax return. If you use tax software, you enter the sale date, proceeds, and cost basis into the investment income section. The software calculates your capital gain or loss and places it on Schedule D (Capital Gains and Losses).

If you prepare your return by hand, you transcribe the same information onto Schedule D, then transfer the total to Form 1040. The IRS matches the 1099-B it received from the brokerage against the Schedule D you filed. If the numbers don't match, you'll receive a notice asking you to explain the difference.

If you sold securities at a loss, you still report it on Schedule D. Capital losses can offset capital gains, and up to $3,000 of net losses can offset other income in a single year. Losses beyond that carry forward to future years. This is why accurate reporting matters — losses have real value, and the IRS needs to see them to process your return correctly.

What to do if the 1099-B information is wrong

Contact the brokerage that issued the form as soon as you notice an error. Common mistakes include the wrong sale date, incorrect proceeds, or a cost basis that doesn't match your records. The brokerage has a important date to file corrected forms with the IRS, which varies by year but is usually in February or March.

Ask the brokerage for a corrected 1099-B (sometimes called an amended 1099-B). Request it in writing and keep a copy of your request. Once you receive the corrected form, file an amended tax return if you've already filed. Use Form 1040-X (Amended U.S. Individual Income Tax Return) and attach the corrected 1099-B.

If the brokerage refuses to correct the form or you cannot reach them, you can still file your return with the correct information and attach a written explanation. The IRS will see the discrepancy, but your documentation shows you reported what you actually sold and received. This protects you from penalties if the brokerage's error created a mismatch.

The difference between a 1099-B and other deposit-related forms

Your bank may issue other forms that look similar but serve different purposes. A 1099-INT reports interest earned in a savings account or money market account. A 1099-DIV reports dividends paid by stocks or mutual funds you own. A 1099-MISC or 1099-NEC reports miscellaneous income or non-employee compensation. None of these are 1099-Bs, and none of them document the sale of a security.

If you received a 1099-INT from your bank, that's normal — it means you earned interest and need to report it as income. If you received a 1099-DIV, you own shares that paid dividends. If you received a 1099-B, you sold an investment through a brokerage account at some point during the tax year.

The key distinction: a 1099-B is about selling something you owned. Every other form is about money you earned or received without selling. Your bank deposits are not sales, so they do not generate a 1099-B.

Frequently Asked Questions

Do I need to report large bank deposits to the IRS?

Not directly through a 1099-B. Banks file a Currency Transaction Report (CTR) with the IRS when a single deposit exceeds $10,000 in cash. This is automatic and does not require you to do anything. However, the source of the deposit matters for your tax return — if it's income, you report it as income; if it's a loan or transfer, you don't. A large deposit alone does not create a tax liability.

What if I sold cryptocurrency and didn't receive a 1099-B?

Cryptocurrency exchanges are required to file a 1099-B if you sold crypto for a gain, but not all do. You are still required to report the sale on your tax return, even without the form. The IRS tracks crypto transactions through blockchain analysis and exchange records. Report the sale on Schedule D with the date, proceeds, and cost basis. If you later receive a 1099-B that doesn't match what you reported, contact the exchange to correct it.

Can I file a 1099-B if I lost money on an investment sale?

You do not file the 1099-B — the brokerage does. But you must report the loss on your tax return on Schedule D, even though it's a loss. Capital losses reduce your taxable income and can offset capital gains. If losses exceed gains, you can deduct up to $3,000 against other income in that year, with the remainder carrying forward to future years.

What happens if I ignore a 1099-B I received?

The IRS received a copy of the same form. If you don't report the sale on your tax return, the agency will notice the mismatch and send you a notice of deficiency. You'll owe the tax on the unreported gain, plus penalties and interest. It's far easier to report it correctly the first time, even if the amount is small or you made a loss.

Can someone else file a 1099-B in my name?

No. A brokerage can only file a 1099-B for an account registered in your name with your Social Security number or tax ID. If a 1099-B arrived for an account you don't recognize, contact the brokerage when ready. If you did not open the account, this is a sign of identity theft or fraud, and you should report it to the FTC and file a police report.
