Backup withholding is a tax the IRS takes directly from your income when you do not provide a correct tax ID or fail to report income correctly
The IRS uses backup withholding as a collection tool, not a penalty. When you receive certain types of income — interest, dividends, freelance payments, gambling winnings — the person or business paying you is supposed to have your correct Social Security Number or Employer Identification Number on file. If you do not provide one, provide an incorrect one, or the IRS notifies the payer that you have underreported income in the past, the payer must withhold a flat percentage from your payment and send it to the IRS instead of giving it to you.
The current backup withholding rate is 24 percent. This means if you are owed $1,000 in freelance income and backup withholding applies, you receive $760 and the IRS receives $240. The withheld amount is credited toward your tax bill for that year, so it is not lost money — but it does reduce what you take home immediately.
Backup withholding is different from regular income tax withholding on a W-2 job. It is triggered by specific IRS notices or missing information, not by your W-4 form or tax bracket. Most people never encounter it, but it becomes relevant if you work as a contractor, receive investment income, or have had issues with the IRS.
Key Takeaways
- Backup withholding removes 24 percent from certain income payments when you do not provide a valid tax ID or the IRS flags you for underreporting.
- The payer — your client, your bank, a casino — is legally required to withhold and send the money to the IRS, not to you.
- You can stop backup withholding by providing a correct tax ID, filing missing tax returns, or resolving the issue that triggered the IRS notice.
- The withheld amount counts as a tax payment and reduces what you owe when you file, but you do not receive it back unless you overpaid your total tax for the year.
When the IRS requires backup withholding to start
Backup withholding is triggered by one of three situations. First, you do not give the payer your tax ID when asked. If a bank, brokerage, or employer asks for your Social Security Number on a W-9 form and you refuse or leave it blank, they must withhold. Second, you provide an incorrect tax ID — either by mistake or intentionally. The IRS cross-checks the ID against its records, and if it does not match, withholding begins. Third, the IRS sends the payer a notice that you have underreported income in the past. This notice, called a "backup withholding notice," tells the payer to start withholding on all future payments to you.
The third trigger is the most common for people who have had tax compliance issues. If you received income you did not report on a prior tax return, or if you reported income but the amount did not match what the IRS received from the payer (a mismatch between your return and a 1099 form, for example), the IRS may send a notice to all payers currently paying you. Once that notice is in the system, every payer you work with will withhold 24 percent until you resolve the issue.
You will usually receive a letter from the IRS before backup withholding starts, but not always. Some payers begin withholding as soon as they receive an IRS notice, so you may first learn about it when your payment is reduced.
What income is subject to backup withholding
Backup withholding applies to specific categories of income, not all income. The main ones are interest from banks and investment accounts, dividends from stocks or mutual funds, payments for services as an independent contractor (reported on a 1099-NEC or 1099-MISC), royalties, rental income, gambling winnings, and certain government payments like unemployment or state tax refunds.
Wages from a regular W-2 job are not subject to backup withholding. If you work as an employee and your employer has your correct Social Security Number, backup withholding does not apply — regular income tax withholding does instead. Backup withholding also does not apply to payments under $600 in most cases, though there are exceptions for certain types of income like gambling winnings.
If you are unsure whether a particular payment is subject to backup withholding, ask the payer. They should know based on the type of income and whether they have received an IRS notice about you.
How to stop backup withholding
You stop backup withholding by fixing the underlying problem. If you did not provide a tax ID, provide one now. Complete a W-9 form with your correct Social Security Number and give it to the payer. They will stop withholding once they have it on file, usually within one to two pay periods.
If the IRS sent a notice because you underreported income, you have two main options. First, you can file an amended tax return (Form 1040-X) for the year in question, reporting the income you missed and paying any tax owed. Once the IRS processes the amended return and the account is settled, they will send a notice to all your payers telling them to stop withholding. This process takes several weeks to several months depending on IRS processing times.
Second, if you believe the IRS notice is wrong — for example, the payer reported income to the IRS that you never actually received — you can contact the IRS directly to dispute it. You will need documentation showing the income was not yours or was reported in error. Call the IRS at the number on the notice or visit an IRS office in person with your records.
Once backup withholding stops, the payer will resume paying you the full amount. The withheld money already sent to the IRS stays there and is credited to your tax account for that year.
How backup withholding affects your tax return
When you file your tax return, the backup withholding that was taken from your income appears as a tax payment, similar to regular income tax withholding from a W-2 job. The payer reports it to the IRS on a 1099 form, and you report it on your return. The IRS subtracts it from your total tax bill for the year.
If the 24 percent withheld is more than your actual tax bill, you will receive a refund of the overage. If it is less than what you owe, you will owe the difference when you file. For example, if $2,400 was withheld from your income but your total tax for the year is $1,800, you will get a $600 refund. If your total tax is $3,200, you will owe $800.
The key point is that backup withholding is not a separate penalty or fine — it is treated as a payment toward your tax bill. You do not lose the money; it just goes to the IRS before you see it, and you settle up when you file your return.
Frequently Asked Questions
Can I get the backup withholding money back before I file my tax return?
No. Once the IRS receives the withheld amount, it stays in your tax account until you file your return. If you overpaid, you will receive a refund after the IRS processes your return, which typically takes four to six weeks. If you need the money urgently, your only option is to resolve the underlying issue (provide a correct tax ID or file an amended return) so withholding stops on future payments.
What if I disagree with the IRS notice that triggered backup withholding?
Contact the IRS using the phone number on the notice you received. Bring documentation showing the income was not yours, was reported in error, or was already reported on a prior return. You can also visit an IRS office in person. The IRS will investigate and send a new notice to your payers if the original notice was incorrect.
Does backup withholding affect my credit score?
No. Backup withholding is a tax withholding mechanism, not a debt or delinquency. It does not appear on your credit report and does not affect your credit score. However, if the underlying issue is unpaid taxes, that can eventually affect your credit if it remains unresolved for years.
Can my employer withhold backup withholding from my W-2 wages?
No. Backup withholding applies only to specific types of income like 1099 payments, interest, and dividends. Regular W-2 wages are not subject to backup withholding. Your employer withholds regular income tax based on your W-4 form instead.
