Client testimonials

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.

We’ve started working with Frost Tax Law on our ERC claim that had stalled and was getting extremely frustrated with working with (or dealing with) the IRS. He was able to expedite a quick response as well as getting our claims approved and paid when I was barely able to get a response from the IRS. Highly recommend
