What IRS documents are acceptable?
Below are five examples of acceptable IRS documents:
- IRS CP575
- Form 8109 (quarterly tax coupon)
- Letter 147C
- IRS fax cover sheet with legal business name and tax identification number
Note: Acceptable IRS documents are ones generated by the IRS and not documents generated by the supplier. For example, a W-9 is a form generated by the supplier and sent to the IRS; therefore, it would not be acceptable to the NSC.
