Assessment Notice vs Tax Bill
A real estate assessment notice is not the same as a tax bill. The assessment notice shows the property’s assessed value. The tax bill uses assessed value and the tax rate to calculate what is owed. If assessed value looks wrong, start with the Commissioner of the Revenue or assessment review. If payment amount, due date or posted payment is the problem, start with the Treasurer/payment record.
| Question | Start Here | Why |
|---|---|---|
| Is my assessed value wrong? | Commissioner of the Revenue / assessment review. | Assessment concerns are not changed by the Treasurer’s payment office. |
| Did my payment post? | Treasurer payment history. | The Treasurer bills, collects and posts tax payments. |
| My name or address is wrong on the bill | Commissioner of the Revenue or account records. | Bill information corrections may require revenue/assessment record updates. |
| I received multiple bills | Treasurer plus parcel/special district review. | Multiple bills can relate to special districts, new construction, town taxes or land/improvement billing. |
