What IRS Private Delivery Service Should I Use to File or Pay Taxes on Time?

Filing and paying your taxes on time is a requirement each year. But what if you prefer not to use the U.S. postal service? What IRS private delivery service options do you have?

The IRS has approved certain private delivery services that meet the “timely mailing as timely filing/paying” rule for tax returns and payments. That means as long as you mail your return and payment by the tax deadline, your return and payment are considered on time for the IRS’s purposes.

Keep these points in mind when using these services:

  • It’s a good idea to request written proof of the mailing date. You should retain this documentation with your copies of your tax return for your records.
  • Private delivery services can’t deliver to P.O. boxes. You must use the U.S. Postal Service if you plan to mail your payment to an IRS P.O. box. You can find the physical address for Submission Processing Centers for IRS Private Delivery Service packages on the IRS website.
