Yes. Sections 31-37 of the APVAT Act 2005 provide for taxpayers to appeal against a tax assessment or any decision made by the Commercial Taxes Department. If the taxpayer is not satisfied with the decision made by the officer not above the rank of Assistant Commissioner (CT) he can file an appeal with the Appellate Deputy Commissioner.
If you are dissatisfied with the decision of the Appellate Deputy Commissioner, you may, within 60 days of the date of the notification of that decision, file an appeal with the Appellate Tribunal. You must send to the Commercial Taxes Department a copy of appeal which you have filed with the Appellate Tribunal.
If you fail to file a VAT / TOT return and receive a unilateral assessment made by the Commercial Taxes Department, you cannot appeal against that assessment. The only way to challenge this assessment is to file the VAT / TOT return as required by the AP VAT Act 2005.
