Backup Withholding: What It Is and Who Has to Pay It

Backup withholding is one of those tax mechanisms that can seem deceptively simple: Normally, it’s used by the IRS to ensure that individuals and businesses report and pay the appropriate taxes on certain types of income. This withholding applies when a taxpayer fails to provide a correct Taxpayer Identification Number (TIN) or has underreported income in previous tax filings. The goal of this withholding is to prevent tax evasion and ensure that the IRS collects the necessary taxes in cases where reporting compliance may be questionable.

Understanding backup withholding is important for both payees and payers. If you are subject to it, a portion of your income will be withheld and sent directly to the IRS. This can have a significant impact on cash flow, particularly for independent contractors, investors, and others who rely on non-wage income. Knowing when and why backup withholding applies can help you avoid unnecessary tax complications and ensure compliance with IRS regulations.

How Does Backup Withholding Work?

En backup withholding applies, the payer of the income is responsible for withholding 24% of the payment before issuing the remaining balance to the payee. The withheld amount is then sent directly to the IRS on behalf of the taxpayer. This process ensures that the IRS collects taxes from individuals who may have a history of underreporting income or who have not provided the necessary tax identification details.

The payer is required to report the total amount of backup withholding to both the IRS and the payee. This is typically done using Form 1099, which details the amount of income paid and the amount withheld. The payee can then use this information when filing their tax return to claim credit for the taxes already withheld.

For example, if a freelancer receives a $5,000 payment subject to backup withholding, the payer will withhold 24%, or $1,200, and send it to the IRS. The freelancer will receive the remaining $3,800 and will be able to claim the $1,200 as taxes already paid when filing their return. If the amount withheld exceeds the total tax liability, the taxpayer may receive a refund.

When Does Backup Withholding Apply?

Backup withholding applies in several scenarios, including:

• When a payee fails to provide a correct Taxpayer Identification Number (TIN) to the payer.
• When the IRS notifies a payer that a specific taxpayer has underreported interest or dividend income.
• When a taxpayer fails to certify that they are not subject to backup withholding on a required tax form, such as Form W-9.
• When a taxpayer has been notified by the IRS that they are subject to backup withholding due to previous tax compliance issues.

The current backup withholding rate, as of 2025, is 24%. This means that if the withholding applies to your income, 24% of the total amount will be withheld and sent directly to the IRS. While this may seem like a steep percentage, taxpayers who have had amounts withheld can later reconcile this when filing their tax returns. If too much was withheld, they may be entitled to a refund, but if they owe additional taxes, this amount will be credited against their total tax liability.

Types of Payments Subject to Backup Withholding

Withholding can be applied to various types of income, including but not limited to:

• Interest payments
• Dividendos.
• Rents, royalties, and other income reported on Form 1099
• Payments made to independent contractors
• Certain gambling winnings
• Stock sales or redemptions

It is important to note that wages and standard employee salaries are not subject to backup withholding, as they are already covered under regular payroll withholding rules. Businesses making payments to freelancers and independent contractors should be particularly mindful of its requirements, as failing to withhold when necessary can lead to compliance issues and penalties.

How to Avoid Backup Withholding

To prevent backup withholding from affecting your income, consider the following steps:

• Ensure that the Número de Identificación de Contribuyente (TIN) provided on tax forms is accurate and matches IRS records. The IRS may impose the withholding if the TIN is incorrect or does not match the name on file, so double-checking for accuracy is essential.
• Complete and submit Form W-9 correctly when requested by a payer. This form certifies your TIN and confirms that you are not subject to backup withholding. Failing to submit it or providing incorrect information can lead to withholding.
• Respond promptly to any IRS notices regarding underreported income or discrepancies in tax filings. If the IRS notifies you of a mismatch or an issue with your reported income, addressing it quickly can prevent it from being applied to future payments.
• Resolve any outstanding tax issues that may have triggered withholding in the past. If you have been subject to backup withholding before due to underreported income, paying any owed taxes and correcting past discrepancies can help remove the withholding requirement.
• Stay compliant with IRS regulations by keeping your tax records up to date and ensuring all tax forms are properly filed. If you receive income subject to Form 1099 reporting, make sure that all necessary tax payments are made to avoid being flagged for withholding in the future.

Not everyone can avoid backup withholding. Individuals who have a history of underreporting income or those who have received multiple IRS notifications about discrepancies may remain subject to it until they resolve their tax compliance issues. By taking proactive steps to maintain accurate tax records and respond to IRS requests, most taxpayers can prevent unnecessary withholding and retain full access to their income. To prevent this from affecting your income, consider the following steps:

• Ensure that the Taxpayer Identification Number (TIN) provided on tax forms is accurate and matches IRS records.
• Complete and submit Form W-9 correctly when requested by a payer.
• Respond promptly to any IRS notices regarding underreported income or discrepancies in tax filings.
• Resolve any outstanding tax issues that may have triggered backup withholding in the past.

By staying compliant with IRS regulations and keeping tax records up to date, you can prevent unnecessary withholding and retain full access to your income.

What to Do If Backup Withholding Is Deducted

If backup withholding is applied to your income, the withheld amount will be reported to you and the IRS on Form 1099. You can claim the withheld amount as a credit when filing your annual tax return. If excess tax was withheld, you may be eligible for a refund.

To ensure that you receive credit for backup withholding, carefully review your tax documents and report the withheld amount accurately when filing your taxes. Keeping thorough records of all 1099 forms and withholding amounts is essential. If you believe that withholding was applied in error, you may need to contact the IRS or the payer to correct the issue.

If you need to address an incorrect withholding issue, it may be helpful to reach out to the payer who withheld the tax. They may be able to correct the problem before tax season, saving you from waiting until you file your return to reconcile the amount. Additionally, keeping track of previous IRS notices and resolving any outstanding tax liabilities can help you avoid future backup withholding issues.

The Final Word on Backup Withholding…

Backup withholding serves as a safeguard for tax compliance, ensuring that taxpayers accurately report and pay taxes on certain types of income. While it can seem like an inconvenience, understanding when it applies and how to avoid it can help individuals and businesses stay compliant and avoid unnecessary financial disruptions. By keeping tax records in order, providing correct TINs, and addressing any IRS notifications, taxpayers can minimize the likelihood of withholding and ensure a smooth tax filing process.

Staying proactive with tax compliance not only helps prevent backup withholding but also makes tax season much easier. Whether you are an individual receiving 1099 income or a business responsible for making payments, knowing the rules around withholding can save time, money, and frustration in the long run. If you are unsure about your tax situation, consulting with a tax professional can provide additional guidance and help ensure that you are meeting all IRS requirements.

Backup Withholding: FAQ

1. What is backup withholding, and when does it apply?

Backup withholding is a mandatory tax withholding that applies when a taxpayer fails to provide a correct Taxpayer Identification Number (TIN) or has been flagged by the IRS for underreporting certain types of income. It primarily affects payments such as interest, dividends, royalties, and some non-employee compensation. The IRS requires payers, such as banks and investment firms, to withhold 24% from payments made to individuals or businesses that do not meet reporting requirements. This withholding ensures that taxes are collected upfront if there is a risk of underpayment or incorrect reporting.

2. How do I know if I am subject to backup withholding?

Taxpayers will typically receive a notice from the IRS or a financial institution if they are subject to backup withholding. The IRS may notify a payer that a specific taxpayer has underreported interest or dividend income, which can trigger withholding. Additionally, if a financial institution or payer does not have a correct TIN on file, they may begin withholding automatically. Reviewing tax forms such as Form 1099-INT or Form 1099-DIV can help determine whether it has been applied to received payments.

3. Can backup withholding be refunded?

Yes, any amount withheld under backup withholding can be claimed as a credit on the taxpayer’s annual federal tax return. Since  withholding is considered a prepayment of taxes owed, taxpayers who have had too much withheld may receive a refund when they file their return. To ensure they receive proper credit, individuals should keep records of all payments subject to withholding and verify that the withheld amount appears on their tax documents.

4. How can I prevent backup withholding from affecting me?

To avoid backup withholding, taxpayers should ensure that they provide accurate and up-to-date TINs to all payers who require them. Completing Form W-9 and submitting it to banks, brokers, and other financial institutions helps confirm that the correct TIN is on record. Additionally, taxpayers should promptly address any IRS notices related to underreported income to prevent withholding from being enforced.

5. What types of income are subject to backup withholding?

Backup withholding can apply to a wide range of payments, including interest, dividends, royalties, rents, and non-employee compensation reported on Form 1099. It may also be applied to certain gambling winnings, broker transactions, and even some government payments. However, it does not apply to wages or salaries, as these are subject to regular payroll withholding.

6. What should I do if backup withholding is applied incorrectly?

If backup withholding is applied in error, the first step is to contact the payer who withheld the funds and verify that they have the correct TIN on file. If the issue is related to an IRS notice about underreported income, taxpayers should respond to the IRS with the necessary documentation to correct the issue. If the withholding cannot be reversed by the payer, the withheld amount can still be recovered when filing a federal income tax return.
