My family has used their tax service for many years. I had the opportunity to work with them to prepare taxes. I am so grateful for the patience and diligence to help me file the taxes by the extension deadline. I highly reccomend BRN and their professional staff.

If you are looking for an excellent tax person, you must call Dave Ruch. He's easy to get a hold of and very knowledgeable. We have referred a lot of clients to Dave and everyone has been extremely happy with his service. He's also one of the only tax people we have found that thoroughly understands the tax implications of short sales and foreclosures. "Dave is recognized by the IRS as one of the premier tax accountants in San Diego."

Tim has been super helpful. I'm trying to sort out some complicated financial stuff (complicated to me, maybe not to him). He can easily see when Im lacking knowledge or have a misconception and he takes the time to explain. He explains in way I can understand, but it doesn't come across as condescending at all. Unfortunately, now I get why so many people dislike the IRS. Ignorance was bliss, so to speak. But since they can't be avoided, I'm glad I have tim and BRN tax to keep me out of trouble.
A. Life Less Wasteful By Caroline Joy
Nov 02, 2018 Report
I truly had a terrible experience that I am still dealing with months after tax season. I had to get an amended return because of a mistake that was made on their end, and apparently the only way to get the amended return to the IRS was to snail mail it. After mailing it and waiting 2 1/2 months to hear back, I received a late payment notice from the IRS and am currently on the phone with them trying to sort it out still. I will not be returning here to get my taxes done again.
