Since the goal is to pay enough to cover each installment amount, we suggest adding 5% to the total of last year's amount. Divide that amount by the number of payments you want to make and send in that payment. After you receive the actual 2022 tax bill, you may readjust your amount accordingly. The full amount of the tax owed must be paid by each due date to avoid a late payment penalty charge.
The actual 2022 real estate tax amounts will not be available until April 28, 2023. You may, however, estimate the amount by using a 5% increase of your prior year's tax as a guide. Simply take that amount and divide it by the number of payments you wish to make.
Formula . . . Multiply your 2021 tax by 1.05 to determine an estimate of your 2022 tax. Decide on how many payments you would like to make and divide the 2022 estimate by that number. This will determine your monthly payment.
For example . . . if your 2021 tax was $4,000, multiply that by 1.05 to get an estimate of $4,200 for the 2021 tax. If you plan on sending a monthly payment from December to August (a total of 9 months), divide $4,200 by 9 to determine a monthly payment of $467.
Another example . . . You would like to make 4 payments between December and August. Divide the $4,200 estimate by 4 to determine a periodic payment of $1,050.

Attn: Prepayment Program
- Tax payments made after the due dates incur a state-imposed 1.5% monthly interest late payment penalty on the unpaid balance.
- Continue to make your payments. When there is enough to pay a full installment (plus interest and penalties if applicable), that amount will be used to pay your taxes; a statement showing your balance will be sent to you. If the balance in your payment plan is not sufficient to satisfy a full installment, the funds will not be applied to your taxes.
