Timberline reached out to me when a major tax issue reared its ugly head and I'm so glad they did. I had been working with another big tax resolution firm and they weren't living up to their billing, so I hired Timberline. They were so attentive and understanding, communicating with me constantly about what was going on and answering my myriad questions. I'd highly recommend them!!

Adam Holleran and his team got it done! I have been dealing with over $400,000 in IRS tax issues for years after my business closed. I have worked with several lawyers who could not make this happen and Adam was able to accomplish what others were not. Thank you Adam. I can't wait to hand your contact information to the first friend or colleague who asks.

Took a little time but they kept going after the IRS and got 3 years of penalties and interest returned. Great company

From start to finish Timberline was open, transparent and hosst about what they could do for me. Talking to Steve, Sam And Melissa gave me a sense that they really knew what they were doing and did not make any promises that they could not keep. In my case, they determined that they could not help me as the penalties were less than the price they charged, so they refunded my paymnts immediately and also gave me good advice on how to deal with the IRS to clear up the bill. Timerline was open and honest about everything they did and kept their promise about the refund with no hassles.

Timberline Tax Group is amazing!! Adam Holleran & Dillion McDonald settled our tax issues resulting in a ridiculous tax lien that I have worked on for several years, They got it wiped out in around two months. They even found that the IRS owes us money back. Timberline is outstanding at what they do. If you have any issues you need to give them a call.

I just wanted to take a minute to share my excellent experience working with Jordan and Adam in resolving my IRS and Mass State tax situation. They made it very easy for me to work with them in getting the required paperwork and forms and helped me every step on the way to resolving my situation. I would highly recommend them to anyone who is attempting to resolve their tax situation.
