Can I pay with a credit card?

County and School property tax bills can be paid by mail using the return envelope that comes with the bills, or in person at the Government Center, 87 Reads Way, in New Castle. Residents can also pay with a credit card. Major credit cards are accepted through Paymentus, which charges users a transaction fee based on the amount of the bill (fees are 2.5% of the total transaction). Paymentus can be reached by calling 1-877-225-7351

Does my bill have to be paid in total by the due date?

Yes. Any balance that remains on your account as of the following business day (for the 2018 – 2019 tax cycle, that is October 1, 2018), will be subject to an initial 6% penalty for County line items and 5% for School line items, and a 1% penalty each month thereafter on all line items.

How does the assessment relate to the value of the property?

Assessment value reflects the market value of your property in 1983 – the last time property values were assessed Countywide. The current value of a property may be higher or lower.

Why is the due date on my bill August 31, 2018 when the 2018 – 2019 taxes are not due until October 1, 2018?

Your bill will only have the due date of August 31, if your account has a delinquent balance. This “Due Date”, is the date by which any delinquent balance (shown in the “Prior Balance” fields) and any penalty (shown in the “Penalty” fields) must be paid in order to avoid further penalty. The 2018 – 2019 taxes (shown in the “Total Current Tax” fields) don’t need to be paid by August 31; they can be paid without penalty by October 1
