You mail Form 941 to the IRS address that matches your business’s state and whether you’re sending it with or without a payment, or you can avoid mailing entirely by e‑filing instead.

Quick Scoop

1. The core rule

Where to send Form 941 depends on two things:

  • The state or U.S. territory where your business is located.
  • Whether you’re mailing the form with a check/money order (payment) or without payment.

The IRS routes these to different processing centers (for example, Kansas City, Cincinnati/Louisville, Ogden) based on that combination.

2. Typical destinations (high‑level)

While you must always confirm the exact address for your situation in the current IRS instructions, here’s the general pattern many recent tables show:

  • Many East and some Midwest states, without payment → Department of the Treasury, Internal Revenue Service, Kansas City, MO (64999 series ZIPs).
  • Those same states, with payment → Internal Revenue Service lockbox addresses such as Cincinnati or Louisville P.O. Boxes.
  • Filers with no legal residence or principal place of business in any state (for example, some U.S. territories) often use Ogden, UT for returns without payment.
  • Exempt organizations, governmental entities, and tribal governments have a special address in Ogden, UT 84201‑0005 for returns without payment, with payments generally going to a Louisville P.O. Box.

Because these addresses and ZIP codes change periodically, rely on current instructions rather than copying an older table.

3. How to find your exact address fast

To get the precise, up‑to‑date address for your Form 941:

  1. Go to the official IRS Instructions for Form 941 and look for the section titled “Where To File.”
  1. In the mailing table, find the row for your state or territory.
  2. Use the column for “without a payment” if you are not including a check or money order, or the “with a payment” column if you are.
  1. Copy that full address exactly, including any P.O. Box and ZIP+4.

If the business is an exempt organization or a governmental/tribal entity, use the special filing address row rather than the regular state row.

4. Mailing vs. e‑filing

You have two main options:

  • Mail (paper filing)
    • Send via USPS to the correct IRS address from the current instructions.
    • You may also use an IRS‑approved private delivery service (like FedEx or UPS) to the IRS street addresses listed for private delivery, which can give you tracking and proof of delivery.
* Paper can be slower and more prone to delays or unnoticed errors.
  • E‑file (recommended)
    • The IRS and many payroll/tax providers strongly encourage e‑filing for faster processing and fewer errors.
* Many modern guides emphasize e‑file as the “default” and paper mailing as the fallback.

5. Why the exact address matters

Using the wrong address can lead to:

  • Delayed processing , especially around quarterly deadlines.
  • Possible failure‑to‑file penalties if the IRS treats the return as late because it was misrouted; these can be 5% of the unpaid tax per month, up to 25%.

So before you drop Form 941 in the mail, always double‑check against the current IRS instructions for that quarter and year. TL;DR:
Check the latest IRS Instructions for Form 941 , go to “Where To File,” and use the row for your state and whether you’re sending with or without a payment —those instructions control exactly where to mail Form 941 right now.
