Hiring independent contractors is a great way to scale your business, but it comes with tax responsibilities. One of the most critical details when filing 1099 forms is ensuring the contractor’s Taxpayer Identification Number (TIN) is accurate. But what happens if the TIN is incorrect?
If the TIN is incorrect, the IRS may impose penalties and require you to correct the error. Additionally, you may be subject to backup withholding.
What Is Backup Withholding?
Backup withholding is a mandatory tax withholding that applies when a contractor provides an incorrect TIN or fails to provide one at all. The IRS requires payers (businesses) to withhold 24% of payments to the contractor and remit them directly to the IRS until the issue is resolved.
What payments are subject to backup withholding?
There are several payment types, including:
- Commissions, fees, or other contractor payments
- Attorney’s fees
- Interest payments
- Dividends
- Payment card and third-party network transactions
- Rents, profits, or other gains
- Royalty payments
When Does Backup Withholding Apply?
Your business must apply for it if:
- The TIN provided is incorrect or doesn’t match IRS records.
- The contractor fails to provide a TIN on Form W-9.
- The IRS notifies you that the contractor is subject to backup withholding due to underreporting.
Who is exempt from Backup Withholding?
Some independent contractors might be exempt from backup withholding. Exempt contractors include:
- Tax-exempt organizations
- Government agencies
- Corporations

The Cost of Non-Compliance
Failing to apply backup withholding when required can result in IRS penalties for businesses. If a payer does not withhold when required, they may be liable for the full 24% withholding amount, along with additional fines and interest. Moreover, failure to file correct information returns can lead to further penalties ranging from $60 to $310 per form, depending on how late the correction is made.
What If Backup Withholding Has Already Been Applied?
If backup withholding is already in place, businesses must:
- Continue withholding 24% from payments until the contractor provides a correct TIN.
- Report the withheld amounts on Form 945 (Annual Return of Withheld Federal Income Tax).
- Issue Form 1099-NEC or Form 1099-MISC to the contractor, reporting both the payments made and the amount withheld.
- Remit the withheld taxes to the IRS following the required deposit schedule.
What Happens When Backup Withholding Is Overpaid?
When you overpay tax as a payer, the excess can be refunded to the payee, just like other federal income tax overpayments. Here’s how the process works:
- Reporting Backup Withholding on Form 1099
As the payer, when you withhold backup withholding tax from your payee’s income, you’ll report the amount withheld on an information return, such as Form 1099 (e.g., Form 1099-INT for interest income or Form 1099-MISC for miscellaneous income).
This form provides the IRS and the payee with the total income paid and the federal income tax withheld during the year. - Ensuring Accurate Filing on the Payee’s Tax Return
At the end of the tax year, your payee must file a federal income tax return, reporting all sources of income and any taxes withheld, including the backup withholding you reported on Form 1099.
The amount you withheld and reported will be included as part of the total federal tax withheld for the year. - Checking for Overpayment
During the tax return review process, the IRS determines whether the payee’s total tax liability has been covered by the amounts withheld throughout the year, including the backup withholding you handled.
If the total tax withheld exceeds the payee’s tax liability, the IRS considers it an overpayment. - Issuing a Refund for Overpayment
When an overpayment is identified, your payee becomes eligible for a refund.
The IRS will issue the refund, which includes any backup withholding that was more than what they owed in federal taxes.
