Backup withholding acts as a safety measure for the IRS to ensure taxes are collected on specific types of income, especially when there’s uncertainty about whether the recipient will accurately report it. In this process, the payer holds back a flat 24% of the payment and forwards it to the IRS instead of the recipient.
When does backup withholding kick in?
- Missing or Incorrect Taxpayer Identification Number (TIN): If the recipient fails to provide their TIN (like a Social Security Number or Employer Identification Number) to the payer, or if the provided information is incorrect, backup withholding is required.
- Underreported Income: If the IRS notifies the payer that the recipient is subject to backup withholding due to underreported income.
If backup withholding applies to a payment reported on Form 1099-MISC (in box 4), the payer must note this on the form when submitting it to the IRS. They also need to withhold the correct amount and report it to the IRS.
In essence, backup withholding ensures taxes are collected on specific income types, even if the recipient doesn’t fully meet tax reporting requirements.
