S. Income tax payments. Each individual who is required to file a return for federal income tax purposes must complete this Form to obtain an IRS Form W-9 and report all federal income tax withheld and paid to the IRS. (Note: Individual taxpayers must submit Tins and certifications for all taxable years for which they are paying tax including the current year. See IRS Publication 926, Payment of Overdue Federal Income Taxes for more information about payment of unpaid federal income tax.) To obtain an Authorized W-9 form for the reporting year, use Form 941 and Form 941-SS, Return of Taxpayer Identification Number (TIN). The W-9 form must be issued by the responsible employer, not authorized agents of the employer. For more information, see IRS Form 941. The IRS requires that each Form 941 be stamped “Authorized by”. The stamp on Form 941 is not sufficient to indicate that the Form is “Authorized by” an individual. Also see IRS Form 941-S.
