With Tax Monitoring Service also known as Payment Validation Service, NTS will follow-up on all parcels after each tax due date to ensure that taxes were paid timely. Depending on the completion of the Agency’s payment posting, reporting is sent to you no later than 45 days and includes the original amount due, amount paid, over payment or shortages, original due date and date paid. If we discover the taxes were not paid or partially paid, NTS will report the amount unpaid, penalty and/or interest assessed and payoff date by way of NTS Delinquent Reporting (DTR)
