WHAT IS TIN MATCHING?<\/span><\/b>\u00a0<\/span><\/h2>\n

TIN Matching<\/span><\/b> is an IRS e-services program that lets authorized payers check whether a vendor’s name and taxpayer identification number (TIN) combination agrees with IRS records before they file information returns. It helps accounts payable catch bad data before it causes penalties or backup withholding.<\/span>\u00a0<\/span><\/p>\n

WHY IT MATTERS IN PROCUREMENT<\/span><\/b>\u00a0<\/span><\/h2>\n

Incorrect or missing TINs are a common cause of information return errors. When the IRS tells a payer that a payee’s name and TIN do not match, the payer must follow a set notice process and may have to begin backup withholding.<\/span>\u00a0<\/span><\/p>\n

TIN Matching lets the payer find mismatches earlier. It sits alongside a collected W-9, not in place of it. Access is limited to eligible payers and their authorized agents, so confirm eligibility on IRS.gov and read <\/span>AP compliance guidance<\/span><\/a> with your tax team.<\/span>\u00a0<\/span><\/p>\n
