Key facts

  • Utah splits paper Form TC-40 returns by address: return with payment (tax due) vs. return without payment (refund or zero balance) — mailing to the wrong one can delay processing.
  • Make checks or money orders payable to the "Utah State Tax Commission".
  • Same street address for both — only the ZIP+4 extension differs, so double-check it before mailing.
  • A mailed return is generally considered filed on time if it is postmarked by the state filing deadline — sign and date it, since an unsigned return isn't considered filed.
  • PostPal prints your return and hands it to USPS the next business day for $5 — no printer, envelope, or trip to the post office.
