# Print and mail your US return

Pop Books helps you prepare your return. It does not send anything to the IRS. You print the return and mail it yourself.

Before you can print

  1. Fix every error the review shows. Each one has a Go to button that takes you to the field.
  2. Look at any figure you typed over the calculated one and confirm it.
  3. Accept the license terms and the statement on how your tax information is used.
  4. Mark the return as reviewed. If you change the return afterwards, you review it again.

Printing and signing

Open the filing package and choose Print. The first page is a cover page; then come the lines of each form. Sign and date the return before you mail it. If you are filing jointly, both of you sign. Attach what the form tells you to attach, such as copies of your W-2 forms, and keep a copy for yourself.

Where to mail it

The address depends on your state and on whether you enclose a payment. Check the current mailing address on irs.gov/filing before you mail the return. The package only prints an address when it has been confirmed for the tax year; otherwise it sends you to the IRS table.

Sending it with tracking or delivery confirmation is a good idea.

If you owe tax

Pay by check or money order made out to "United States Treasury", following the Form 1040 instructions for what to write on it, or pay online with IRS Direct Pay at irs.gov/payments/direct-pay. The payment is due by the filing deadline, usually April 15 of the year after the tax year.

Next year

If you will owe tax again, plan to pay estimated tax during the year. See the article on estimated tax payments.

Pop Books is software. It doesn't act as a tax preparer and doesn't give tax or legal advice. You are responsible for what you file.
