Real Estate Assessments & Taxes
Real estate assessments are released in February and notices are mailed to every property in the county. Once tax rates are set by the Board of Supervisors, taxes are calculated and bills are generated. Real estate taxes are paid in two installments due July 28 and December 5. For most, bills are sent electronically to your mortgage company.
Vehicle Taxes & Fees
Values for most vehicles are determined using a recognized pricing guide or, for new models, as a percentage of the MSRP. Once tax rates are set by the Board of Supervisors, taxes are calculated. Bills are mailed throughout the summer and are due October 5. For vehicles purchased or moved into the county on or after July 1, bills are mailed in January the following year and are due February 15. Vehicle registration fees are billed at the same time as the tax.
Business Taxes
Businesses pay taxes based on the value of their tangible properties such as furniture and fixtures, machinery and tools, and computer equipment. Business vehicles are taxed like other vehicles. In addition, most businesses must obtain a business license. Depending on the type of business, other taxes may apply.
Other Taxes & Fees
You can also register your dog and purchase the dog license and pay parking tickets and other delinquent non-tax fees with DTA. As a consumer, you may pay additional taxes that are not administered by DTA. You can see a list of those taxes and rates here.
