Working with this firm has been a great experience. Their experts are sharp, approachable, and always focused on doing what’s best for the client. I wouldn’t hesitate to recommend them to any CPA or advisor.

Ian W.

Extremely professional and helpful. They seem to be incredibly well-staffed, and everyone I spoke to was very pleasant. The services I needed were outside of my price range, but I have no doubt that they deserve what they charge.

I had an excellent experience working with Frost Law, especially with Heather Posey. She expertly handled my complex tax situation with exceptional thoroughness, deep expertise, and unwavering professionalism. Heather went above and beyond to make sure I felt supported throughout the entire process, demonstrating true empathy for my concerns. I was impressed by how efficiently she completed my case in a very timely manner. I highly recommend Heather Posey and the entire Frost Law team to anyone seeking knowledgeable, compassionate, and effective assistance with tax issues.

Client testimonials

Thank you to Heather Posey and Frost Law for helping my client with their tax dispute. As an accountant for over 38 years, I’ve worked with several attorneys over the years, and Heather stands out far above the rest. Her command of tax law, strategic thinking, and proactive communication are exceptional. She helped us resolve a complex federal tax issue efficiently and with great results. Awesome Firm!! Thanks!

Bradley H.

Very communicative and no use of "legaleze" to describe tax situations/complexities!

Keith M.

I found all of the various staff that I interacted with to be exceptionally helpful and understanding of my limited technical abilities on some of the functions that were required to process my Employee Retention Credit claim. I would recommend this firm to any business or individual needing legal advice! Mike Roach/co-owner of Paloma Clothing for the past 50 years.

I found Frost Law Firm online after desperately searching for ways to expedite the long, painful process of getting desperately needed covid-19 pandemic era tax credits in 2024. Their legal team, including Hunter Scott, of this firm literally was one of my life-jackets on the fast-sinking ship of my business. Through their work with the IRS on my behalf, I had 90% of the tax credit refunds in hand by the close of 2025, which helped me turn things around. I highly recommend their expertise when it comes to the tax laws.
