Like most people, you are probably wondering how the new tax laws have impacted you.  While many filers can expect to see a small tax savings when they file their 2018 returns, many people will see their tax bills have actually increased.  Fewer people will be itemizing deductions on their federal return, however, many will still benefit from itemizing on their Oregon returns.  The rules for claiming depedents have changed significantly; some filers will benefit from increased tax savings from their younger children, while people with older children will be worse off.

Our staff are up-to-date on the new laws and will be happy to provide you with information on how they affect your tax situation.  We can also advise you on strategies you can take to minimize your tax bill for next year.

Authored and instructed by April Gutierrez, our nationally-recognized online tax education programs are completed by hundreds of CPAs, EAs and other tax professionals each year. Since 2001, graduates of our Basic Tax Course have consistently achieved the highest overall pass-rates at the Oregon Tax Board exams.

Why Choose Us

Selecting a competent tax preparer or bookkeeper is an important financial decision.  Consideration should be given to the education and experience, and also to knowledge, competence and ethical practices of the firm you choose to work with.

We know that it takes years to learn the complexities of tax law and the experience to master the challenges of delivering quality tax preparation services during the busy tax season.  That's why the majority of our staff are employed year round, while most other tax services hire a new batch of preparers at the start of each season.

Our staff work together as a team, sharing knowledge and experience, to deliver quality services to our clients.

Review by Jesper P

Long story (as) short (as I can)...

I'm a foreign national who moved to the US last year as an intercompany specialist. I have foreign income, property and bank accounts abroad - It sounds eccentric, but it's normal things to most people who have moved from one place to another. To me the US tax system becomes a huge, messy hairball. If you're foreign you know exactly what I mean. If you're American you probably won't understand, but to illustrate: I used to be able to file my taxes via text message in my home country (since we let magic grey boxes called computers compile and precalculate things for us...) If we have questions, the tax authority provides free consultations.

This was my first US tax filing. At first, I went to H&R Block. Complete waste of time. After two meetings @2hrs each, one being with their "Master Tax Advisor", they still hadn't indicated they had the first clue where to even start. Then I did what I should have done from the start and contacted April at PNW Tax, who came to my rescue! After 10 minutes with April I had already come 9 minutes further than I did in four hours at H&RB (who ended up giving me incorrect and probably unlawful recommendations). It took us a while to get through it all, but April was awesome the whole way and most importantly, I felt like I was in good hands with someone who truly was skilled at their job. If you have any kind of complexity in your tax situation, please go ahead and trust PNW Tax to solve it for you.

Review by Ben P

I previously used a different local tax service whereby I owed $1600 IRS and $1300 State Taxes. That service did not assist me with an extension or even advice towards paying because I did not have the means to and I ended up with a wage garnishment. I was hurried in and out and the preparer disappeared until tax-time. I went back this year only to find out I would owe even more money.

Feeling this was not right I left and decided to give PNW Tax Service a try upon the advice of my work colleague/friend. The office is very professional and I did not get a sleezy or hurried vibe at all.  After providing all my information, I felt that Sandee(my preparer) was very knowledgeable and more importantly took the time to help me understand my return and what my deductions were. No false promises were made and everything was done and discussed in a way that made sense. In then end not only did I receive a sizeable refund from the IRS and the State, but she was going to amend my previous years tax return to help refund the amounts I owed. I am very grateful and the $345 I paid was WELL worth it.
