Form 3244, Payment Posting Voucher, is a hand prepared source document. The preparer inputs the SSN/EIN for a taxpayer in the labeled box and puts the required information in the other boxes (MFT/Tax Period/Transaction Received date and Taxpayer name). Form 3244 includes boxes labeled for payment transaction codes so the preparer need only place a check mark in the box to show correct processing of the payment. A box is present to display a designated code indicator. Transcribe, along with other marked information during OE/KV, when present.
