Most, if not all, of these SOB fee estimated assessments are wrong. Very wrong. Consultants at Texas Tax Group (ex-Texas Comptroller auditors) have carefully reviewed the Texas Comptroller’s SOB fee estimation method on SOBF client assessments and found many errors. These audit methodology errors can easily DOUBLE what the business actually owes in SOB fee. Texas Tax Group can help you defend yourself against these harsh and significantly over stated assessments.
