David Oase, CPA
David Oase CPA is an accounting firm providing personalized tax services for your individual needs. Based in Tucson Arizona, our firm has been serving individuals, startups, non-profits, and corporations locally and abroad for generations. We are loved for our level of personal attention not found at many accounting firms.

Getting to know our clients individually provides superior results. I've used David Oase's services for about 15 years and everyone I've dealt with has been efficient, good at what they do, and very personable. They seem to remember from year to year the details of your file which make things go smoothly.
Services
Don't lose out on deductions and credits! You could save thousands of dollars with the right information - make sure your accountant knows YOU. Rest a little easier knowing where your finances are headed. Save money for school, start your business, and plan for retirement with our knowledge and expertise.
When you cannot pay the full amount up front, you can set up an installment system with the IRS. Did you know you can negotiate the installments? We can help! These letters are to tell you there has been a miscalculation made on your tax return, whether they found it or made a change which revealed a miscalculation.

Incredibly professional and quick! It's obvious this business knows what they're doing with both my taxes and customer service. Angelica was so knowledgeable and professional. I'll definitely be back next year!

The staff is absolutely the best in town. Each individual has so much knowledge to help navigate the financial world. By far the best experience I've had when handling my taxes each season. I found it refreshing that they are open year round to help provide understanding for the random finance advisory that I occasionally needed. They are friendly and understanding; you are not just another numbered client. They provided clear and concise explanations and planning for both my short term and long term financial goals. Lucy (office manager) is the sweetest person to greet you over the phone or in

Chan Denson is a wonderful CPA to work with. He's smart, he's present, he listens, and he knows a lot about taxes, tax law, small businesses, human beings, and life in general. I actually ENJOYED working with him on my taxes! He's the kind of person with whom you want to cultivate a long-term working relationship because he evokes trust and demonstrates reliability and competence. He's genuinely curious about my financial goals and about me as a person. Furthermore, Lucy Acedo, who does the firm's administrative work, is a wonderful contact/point-person. She's meticulous in her work, she's responsive

I just moved to Tucson and during the previous year had many life changes. I usually do my own taxes but this year it felt too overwhelming. David got me in quick and handled everything with such ease. I highly recommend!

Tried to do my taxes myself this year after the person I was getting it done from stopped doing taxes. When I was doing it I somehow managed to owe $3500 plus to the IRS. Took it to these guys and spoke with Wally and he took me from owing money to getting a refund in excess of $5k. Wally was straight to the point and I dug his sense of humor. Definitely worth the price I paid and then some. Will definitely be getting my taxes done from him and this place going forward.

David makes taxes feel a little less stressful! He ensures that all of your questions are answered and offers plenty of useful information. He even took us through our previous years paperwork to show us the changes that have taken place with the tax reform, etc. I am confident in Davids expertise and highly recommend him!

We met with David when we first moved to town. We had questions about setting-up our business entity, and about all the logistics of moving our family (and finances) from CA to AZ. His answers were very thorough, and he and his staff are super friendly. It's that time of year... David Oase will make it a breeze.
