You can visit the website, Estimate - ParcelQuest Statewide, to calculate the estimated charge of your supplemental tax bill.

Enter the Assessor's Parcel Number or home address and then click search.

Select the red Supplemental Tax Estimator tab and enter the date of purchase, the purchase price, and click calculate. The estimated charge for your supplemental tax bill will be listed next to line "F".

Supplemental bills (or refunds) are calculated based on the number of months remaining in the current fiscal year after the month in which the supplemental event occurs. A fiscal year runs from July 1 through June 30.

If a supplemental event occurs between June 1 and December 31, only one supplemental tax bill or refund check is issued. This bill, or refund, accounts for the property's change in value for the period between the first day of the month following the event date and the end of the current fiscal year (i.e., the following June 30).

If, however, a supplemental event occurs between January 1 and May 31, two supplemental tax bills or refunds are issued. The second bill or refund accounts for the property's change in value for the entire 12 months of the coming fiscal year, beginning on the following July 1.

If you don't pay your supplemental tax bill by its delinquent date,  you will be charged a 10% penalty per installment. An additional $30.00 cost is added if you are late on the second installment.

Additional Penalties

If the tax bill is issued on the secured roll and you do not pay either installment by June 30th, your property will go into "tax default", and you will be charged a 1.5% penalty per month (18% penalty per year) until the balance is paid.

OR

If the tax bill is issued on the unsecured roll and you do not pay either installment by June 30th, your property will go into "delinquent unsecured", where a lien will be filed against you. A 1.5% penalty per month (18% penalty per year) will accrue until the balance is paid.

- Most mortgage lenders DO NOT pay supplemental tax bills. If your lender makes the payment for the supplemental tax bill, it may increase your monthly mortgage payment.

- Unpaid supplemental bills can lead to Property Tax Sale or Unsecured Collection Enforcement Actions.

- Supplemental tax bills are usually issued and mailed on a daily basis. They are separate bills and in addition to the annual tax bills.
