Reliable Income Tax Service Inc (DBA Reliable Tax) is Portland's oldest professional tax office. Opened in 1945, our family has been providing tax preparation and consulting to our community for over 75 years. ​Through the generations, we have prided ourselves with exceptional customer service to be a team you can rely on.

We have an experienced staff of Licensed Tax Consultants and Licensed Tax Preparers. When you visit our office, you can be confident that you will always be dealing with a licensed tax expert with many years' experience, and yet our rates compare to the national franchises that often employ first-year tax preparers.


Our staff is available year round to answer your tax questions and handle any tax problems that arise. We may close our physical location for part of the year, but we continue to work from home to ensure each client is supported beyond the tax filing season. 

We offer a range of services to help our clients on their path to financial success.  While our primary focus is preparing individual tax returns, we offer so much more than filling out tax forms.  During the tax season, our office is open for walk-in clients. In the off-season, we are available for phone, email, and in-person appointments to answer your questions, provide guidance on any correspondence received from the taxing authorities, and help you plan for the future.
