"Chris did an amazing job negotiating with the IRS on our behalf. They agreed to reduce our $57,000 in tax debt to $12,000 with a payment plan we could handle... As someone who has worked as an accountant my entire career, Chris stands out as someone who has an exceptionally high level of knowledge when it comes to tax laws and negotiations with the IRS."
