Backup Withholding: A Tax the IRS Applies When You Don't Provide Your ID Number

Backup withholding is a tax the Internal Revenue Service takes directly from your income when you fail to provide your Social Security number or Employer Identification Number to a payer — usually your bank, employer, or investment firm. The IRS does not send you a bill. Instead, the payer removes a flat percentage from your payments and sends it to the IRS on your behalf. As of 2024, that rate is 24 percent.

You are most likely to encounter backup withholding if you open a savings account or brokerage account and leave the tax ID field blank, or if you provide an incorrect number. The payer is legally required to withhold and report the money to the IRS. Backup withholding stays in effect until you provide the correct number and the IRS confirms it matches your name.

This is not a penalty. It is a collection mechanism. The money withheld counts as a tax payment toward what you owe at the end of the year, just like regular payroll withholding does. If too much is withheld, you can claim it back when you file your tax return.

Key Takeaways

  • Backup withholding is a 24 percent tax taken from your income when you do not provide or provide an incorrect tax ID number to a payer.
  • The payer — your bank, employer, or investment firm — removes the money and sends it directly to the IRS; you do not receive a separate bill.
  • The withholding stops once you give the payer your correct Social Security number or EIN and the IRS verifies it matches your name.
  • Money withheld counts as a tax payment and can be refunded to you when you file your return if more was taken than you owe.

Who Has to Withhold and Why

Banks, credit unions, investment brokers, and employers are required by federal law to request your tax ID number before they pay you interest, dividends, wages, or other income. If you do not provide one, or if the number you give does not match IRS records for your name, the payer must begin backup withholding.

The IRS created this rule to catch people who intentionally hide income or use false numbers. In practice, most backup withholding cases happen by accident — someone leaves a form blank, writes down the wrong digit, or changes their name without updating their bank records. The payer does not investigate whether the omission was intentional. They straightforward follow the rule and withhold.

Certain types of income trigger backup withholding more often than others. Interest and dividend income from banks and brokerages are the most common. Backup withholding can also explore to payments from gambling winnings, rental income reported on Form 1099-MISC, and some contractor payments.

How Backup Withholding Affects Your Money

If backup withholding starts, you see the effect when ready in your account balance. If you earn $1,000 in interest and backup withholding is in effect, the bank deposits only $760 to your account and sends $240 to the IRS. You do not get a choice about whether the withholding happens.

The payer reports the full $1,000 as income on your 1099 form at tax time, not the $760 you actually received. This means your tax return will show more income than the cash you have in hand. When you file, you will see a credit for the $240 that was withheld, and that amount reduces what you owe or increases your refund.

Backup withholding can last for months or years if you do not fix the tax ID problem. Each payment you receive gets reduced by 24 percent until you provide the correct number and the IRS confirms it. The longer it continues, the more money accumulates in the IRS account under your name.

How to Stop Backup Withholding

To stop backup withholding, you must give the payer your correct Social Security number or EIN and sign a form certifying that the number is correct. For banks and brokerages, this usually means filling out a W-9 form (for U.S. citizens and residents) or a W-8BEN form (for foreign nationals). Ask your bank or investment firm which form they need.

After you submit the form, the payer sends it to the IRS to verify that your name and number match. This verification can take a few weeks. Once the IRS confirms the match, the payer stops withholding on future payments. Backup withholding does not explore retroactively — money already withheld stays with the IRS as a tax payment.

If you have moved or changed your name, make sure the name on the form matches exactly what the IRS has on file. A mismatch in even one letter can cause the verification to fail and backup withholding to continue. If verification fails, contact the IRS directly at 800-829-1040 to check what name and number they have for you.

Backup Withholding and Your Tax Return

When you file your tax return, the IRS matches the 1099 forms the payers sent in against what you reported. If backup withholding was taken from your account, that amount appears as a federal tax payment on your return. You do not have to do anything special to claim it — the IRS applies it automatically.

If the amount withheld is more than what you owe in taxes for the year, you receive the difference as a refund. If it is less than what you owe, you pay the balance when you file. Backup withholding is treated the same way as payroll withholding or estimated tax payments.

Keep copies of any 1099 forms you receive that show backup withholding. The payer should note on the form that backup withholding was applied. If you do not see it marked, contact the payer to request a corrected form before you file your return.

Common Situations That Trigger Backup Withholding

Opening a new savings account without providing your Social Security number is one of the most common triggers. Banks are required to ask for your number before they pay interest. If you leave the field blank or provide a number that does not match IRS records, backup withholding begins on the first interest payment.

Selling stocks or mutual funds through a brokerage can also trigger backup withholding if your account information is incomplete or outdated. If you inherited an account or took over an account from a spouse, the name on the account may not match the name the IRS has for that tax ID number. The brokerage will withhold until you update the account.

Freelancers and contractors sometimes encounter backup withholding when a client pays them on a 1099 form. If the client does not have your correct tax ID or you do not provide one when asked, the client may be required to withhold. This is less common than with banks and brokerages, but it does happen.

What Backup Withholding Is Not

Backup withholding is not a penalty. The IRS is not punishing you for a mistake or late payment. It is a way to collect tax on income when the payer cannot verify your identity. The money goes toward your tax bill, not into a penalty account.

Backup withholding is also not the same as regular payroll withholding from a job. Payroll withholding is based on the W-4 form you fill out with your employer and is meant to estimate your annual tax liability. Backup withholding is a flat 24 percent applied to specific types of income when a tax ID is missing or wrong.

Finally, backup withholding does not mean the IRS is investigating you or that you have done anything wrong. It is an automatic process that happens whenever the conditions are met, regardless of intent. Millions of people experience it at some point, usually by accident.

Frequently Asked Questions

Can I get the money back that was withheld?

Yes, but only if you overpaid your taxes for the year. The withheld amount counts as a tax payment, so when you file your return, the IRS applies it to what you owe. If you owe less than what was withheld, you receive the difference as a refund. If you owe more, the withholding reduces what you have to pay.

How long does it take to stop backup withholding after I provide my number?

It typically takes two to four weeks for the IRS to verify your name and number after the payer submits your form. During that time, backup withholding may continue on new payments. Once verification is complete, the payer stops withholding on future income. The payer will notify you when the withholding has stopped.

What if I do not know my Social Security number?

Contact the Social Security Administration at 800-772-1213 or visit ssa.gov. You will need to provide proof of identity and citizenship. Once you have your number, give it to the payer and submit a W-9 form to stop backup withholding.

Can backup withholding explore to my paycheck from my job?

Backup withholding can explore to certain types of job income, but it is rare. It most commonly applies to interest, dividends, and contractor payments. If you are a regular employee with a W-2, backup withholding would only occur if you did not provide your Social Security number to your employer, which is required before you can start work.

Does backup withholding affect my credit score?

No. Backup withholding is a tax matter between you and the IRS. It does not appear on your credit report and does not affect your credit score. It only affects the amount of income you receive from the payer and your tax liability at the end of the year.
