I had several years unfiled returns until paid years and multiple tax liens the staff at colonial tax consultants were very professional and courteous and told me upfront what the fees were not a penny more not one less did the work as promised and settled 179000 in debt for 1800 dollars that and the fees involved were still less than half of what other firms charge and with the less than straight forward practices of other firms colonial delivered exactly what they stated and treated me as if I was the only client they had at the time I would highly recommend them to anyone with a problem with back taxes because you will see results
