Can a taxing unit waive penalty and interest due on delinquent taxes?

State law requires a taxing unit’s governing body to waive penalty and may waive interest on a delinquent tax if the taxing unit or its agent caused an owner’s taxes to go delinquent. The property owner must pay the tax no later than the 21st day after he or she knows or should have known of the delinquency. The property owner must request the waiver before the 181st day (six months) after the delinquency to receive a refund of the penalty and interest.
