The Harris County Tax Office Collects Property Taxes and Handles Car Registration

HCAD sets your property's value. The Tax Office sends you the bill and collects the money. These are two different agencies. The Tax Office also acts as the county's vehicle registration office, accepting renewals on behalf of TxDMV.

You can pay property taxes, renew vehicle registration, and apply for some tax breaks at Harris County Tax Office locations. Many locations are spread across the county. Property taxes are generally due by January 31 each year — check hctax.net for current deadlines, office locations, and online payment options.
