The homestead exemption reduces the school portion only. This county publishes its district rates, so the split above is theirs rather than an estimate.
The rates shown are the adopted rates for an address in the City of Rockwall and Rockwall ISD. Other cities and school districts in the county adopt their own.
MUD, PID and SUD charges are billed on top of this and are not included. They are common in newer suburban developments and are printed on your bill.
How Rockwall County compares
At 1.58%, Rockwall has the 63rd lowest combined rate of Texas’s 254 counties. The state median is 1.60%, so a home here is charged 0.02 percentage points below the middle of the state.
Texas has no income tax, which is why property tax carries more of the load here than in most states — and why the exemptions above are worth filing for even when the rate looks unremarkable.
The dates that decide what you pay
File for a homestead exemption by 30 April. If you missed it, applications are accepted up to two years retroactively, so it is worth checking whether you ever filed — a surprising number of owners have not.
Protest by 15 May, or 30 days after your appraisal notice arrives, whichever is LATER. There is no filing fee, most districts take it online, and a large share of residential protests settle informally before any hearing. Bring evidence of what comparable homes sold for around 1 January.
