File or amend my return
File online
File your return electronically using My DOR. Simply log in to My DOR using your Secure Access Washington (SAW) user ID. You will need your tax account ID and letter ID, printed on correspondence from the Department, to sign up.
File by mail
Starting with your 2020 tax return, you must file and pay electronically. If you haven’t already, please sign up for My DOR and start e-filing your returns.

If you discover that you made a mistake on a previously filed tax return, you can amend your return. You may go back four years, plus the current year.
Payment methods
Depending on whether you file your return electronically or by mail, the Department offers several types of payment methods.
Self-service payment plan
You may qualify for a self-service payment plan for a billed tax liability. Choose from 3, 6, 9, or 12 month payment terms.
