My case was not an easy one. I frantically needed a tax service to file 5 years of back taxes. David and his staff at IQTaxx made a believer out of me!! I filed my taxes within two weeks and had a minimal balance to the IRS. In comparison to the amount originally billed to me by the IRS the numbers don't compare. They go far and above the call of duty. Best tax preparers in town!  thanks David, Iqtax is 100% recommended.
