We owed the IRS from 2001 to 2005. In 2005, we went to Keltron and it was like an answer to our prayers. They looked over those tax returns for the years we owed, amended those years and months later, our balance was zero. We would recommend Keltron to anyone in the USA. The staffs are very accurate, friendly, and serious about their responsibility to their clients. The Lord had a ram in the bush for us and that ram was George Kolath.
