What forms of payment are accepted by Tax Collectors?

Tax Collectors will generally accept cash, personal checks, and credit card payments. Many will also offer online payments using electronic checks, credit cards, or PayPal. It is common for a convenience charge to be added to online payments.

What are special assessments?

Special assessments are additional charges on a property, which are usually associated with a public improvement that benefits certain property owners, such as a sewer assessment. Special assessments are usually added to the owner's property tax bill.

What are supplemental tax bills?

Supplemental tax bills are additional property tax bills that result from a re-appraisal of a property, usually because of a transfer of ownership or a physical improvement or expansion to the property. If the reappraisal determines that additional taxes are owed, a supplemental tax bill is issued.
