Billy has been preparing our tax return for a few years now and the process they have in place with the portal that you can upload all necessary documents is verily convenient and easy to follow. The price is also reasonable with the fast service they provide. I recommend his business to people.
I’ve used the Sierra-Larregui Tax Group for about 10 years to review or to calculate my federal and state taxes. I’ve been very satisfied with Billy’s work that ensured my tax filings were correct. I started having Billy check and verify my Turbo Tax inputs were correct in a year that we sold a house and bought a house. There were multiple ways for me to mess up the tax filing. Billy found a couple of entries that needed to be moved into a different area and filed my taxes for me. It was worth every penny. Normally, I do the bulk of the data entry in Turbo Tax Business and Home and provide him with the Turbo Tax software application native file to import into his tax software to analyze, check, and assess as an enrolled agent. A few years ago, I had a complicated real estate transaction that Turbo Tax would not let me enter the way I thought it should be entered. Based on my input, I owed more than I earned plus the sale of the property. It was obvious that something was wrong with my input but I could not find where the error was in the data. I sent Billy the Turbo Tax file with everything except the real estate inputs. Which he validated was correctly input. Then he took the real estate information I provided and worked his magic. He filed my taxes with no errors. Again, worth every penny paid for the tax service. With significant changes being made frequently to what has to be provided in the family taxes, I am very pleased to use his tax services. Even if only to validate my input into Turbo Tax is correct. The peace of mind is worth every penny. Or, should I say nickel since the penny is no longer made.
Very happy with my service at Sierra-Larregui Tax Group. They are very knowledgable and helped answered all my questions as a new business owner. I will be doing my taxes with them from now on. I will recommend them to my friends and family.

Billy has been our tax consultant for a number of years. We have been extremely satisfied with his knowledge and expertise in preparing our tax returns.
