The IRS accepts tax payments through the mail, which can be useful if you prefer not to pay online or by phone. Mailing a payment means sending a check or money order directly to an IRS address along with a form that identifies your account. This method takes longer than electronic payment—mail typically arrives within 7 to 10 business days—so timing matters if your payment is due soon.
These articles explain how to prepare a mailed tax payment, which form to include, where to send your envelope, and how to track whether the IRS received it. You'll also learn what information the IRS needs to match your payment to your account and what happens if you mail your payment close to the important date.
