Backup withholding requires a payer to withhold tax from a payment that is not usually subject to withholding. This may happen because: You don't give the payer your taxpayer identification number (TIN) correctly.The IRS notifies the payer that your TIN is incorrect.You have underreported dividends or interest on your income tax return.You fail to certify that you aren't subject to backup withholding. The backup withholding rate is currently 24% of the total amount being paid, effective for the 2018 tax year and beyond. This may be withheld from payments made by business owners, banks, brokerages, or other payers. How Backup Withholding Works When you open an account, make an investment, or begin to receive 1099 payments, you must provide your taxpayer identification number (TIN). In many cases, you must certify that it is correct on a Form W-9. If you fail to do so, or if you have previously underreported income tax, these payments may be subject to backup withholding until the error is corrected or your tax bill has been paid. Payments that may be subject to backup withholding include: Interest payments (Form 1099-INT)Dividends (Form 1099-DIV)Rents, profits, or other income (Form 1099-MISC)Commissions, fees, or other payments for work performed as an independent contractor (Form 1099-MISC)Payments by brokers and barter exchange transactions (Form 1099-B)Payment Card and Third-Party Network Transactions (Form 1099-K)Royalty payments (Form 1099-MISC)Gambling winnings that aren't subject to regular gambling withholding (Form W-2G) Some types of payments are excluded from backup withholding.
