A ten percent (10%) penalty is due on all deficiencies. Deficiencies include failure to post a bond or prepay the tax in full on all contracts requiring the posting of a bond or prepayment of tax before work has begun. This penalty is based on the total amount of tax due on the total contract price. A ten percent (10%) penalty is also due on the tax applicable to monthly compensation not reported timely on subsequent returns.
