Can i mail a check with the 1040x

Yes, you can mail a check with your Form 1040-X, Amended U.S. Individual Income Tax Return. However, it's recommended to use the Electronic Federal Tax Payment System (EFTPS) to make your payment, as it's a more secure and efficient way to pay your taxes.

If you still prefer to mail a check, make sure to:

  1. Write your name and address on the check.
  2. Write "Form 1040-X" and your Social Security number or Individual Taxpayer Identification Number (ITIN) on the memo line.
  3. Make the check payable to the "United States Treasury."
  4. Mail the check and Form 1040-X to the address listed on the instructions for Form 1040-X.

The IRS recommends using a certified mail service, such as USPS Certified Mail, to ensure that your payment is received. You can also use a private delivery service, such as UPS or FedEx, as long as it provides a tracking number.

Keep in mind that if you're making a payment with your amended return, you should make sure to include the payment with your Form 1040-X. If you're making a payment separately, you should include a copy of your Form 1040-X with the payment.

It's also important to note that if you're making a payment with your amended return, you should allow at least 4-6 weeks for processing. If you're making a payment separately, you should allow at least 2-3 weeks for processing.
