File by paper U.S. Postal Service
If you would like to file a paper tax return by mail, you’ll need to download and print our forms and instructions. To find out what form you need to use, visit our file page and select your filing situation.
If you owe taxes, interest will accrue from the original due date. To avoid penalties and interest, you must pay by your return due date.
Before you mail
Make sure you:
- Sign your tax return
- If you’re filing a joint return both people must sign the return
- Make sure your name, address, and social security number(s) are correct
- Check your math
- Attach a copy of your federal return (if not using form 540 2EZ)
- Attach a copy of your W-2
- File your original return, not a copy
Mail your tax return
Visit our mailing addresses page to find out where to mail your return. The address will be different if you’re sending a payment with your tax return versus without a payment.
If you expect a refund, make sure your address is up to date. Visit how do I change my address for more information.
If you owe taxes, visit our payment options.
