Maddix Consultants Tax Group charge a lot. They generally say $200 but they charge $380 at the end.
First any tax consultancy should tell how much customer will get refund and the entire amount should directly deposit on customer account.
These guys will never tell how much total refund they deduct their fee ($380) and they will tell the amount.
Ask exact amount how much you will get refund before they deduct the fee.
