After getting a letter from the IRS saying I owed money from a previous years tax return I decided to have Scottsdale CPA's look it over. Best decision ever. Darren and his team were thorough, professional and quick. In looking through everything they found some errors made by the IRS which significantly decreased the amount I owed. And, they drafted all the correspondence for me to send. Overall they made a complicated situation easy to understand. I wholeheartedly recommend them.
