This company filed a return for us and were going to help us reduce the late fees and penalties. The return they filed had mistakes on it causing extra fees from IRS.
The letter they wrote to IRS about the penalties and interest had horrible grammar mistakes on it; I corrected it and had them retype it before it was sent.
After almost a year from the time we started with JKHarris, we got a response from IRS adding fees to the ones we already had. In short, it cost us the fees to the company, plus the ones IRS added, so we came out way further behind than we were to begin with.
