Worked example: a median-value home in Grayson County
Take a $248,400 home — the county median — used as a primary residence in Sherman, the county's largest city, and served by Sherman ISD, the county's largest school district. The school district taxes $108,400 after the $140,000 school homestead exemption; every other unit taxes the full value.
| Levy | Rate per $100 | Taxable value | Tax |
|---|---|---|---|
| Grayson County | 0.3051 | $248,400 | $758 |
| Sherman ISD (school district) | 1.2342 | $108,400 | $1,338 |
| City of Sherman | 0.5080 | $248,400 | $1,262 |
| Total | $3,358 |
That is $280 a month — what a lender would typically collect in escrow with each mortgage payment. Utility, emergency services or college districts add their rates where they apply.

How Grayson County tax rates changed from 2024 to 2025
The county's own rate stayed at 0.3051 per $100. Its 2025 rate was below the no-new-revenue rate of 0.3248 — the rate that would raise the same amount from properties taxed in both years. So it collects less from existing property than last year.
Of 30 school districts and cities with rates in both years, 9 raised their rate, 10 lowered it and 11 kept it the same. (A rate cut can still mean a higher bill if appraised values rose more.)

How property tax works in Texas
- Who sets the value: each county's appraisal district values property as of January 1. Notices of appraised value go out in the spring.
- Who sets the rates: the county, city, school district and any special districts (utility, emergency services, hospital, college) each adopt a rate per $100 of taxable value, usually in August–September. Your bill is the sum of every unit your property sits in.
- Homestead exemption: school districts must exempt $140,000 of a homestead's value, plus another $60,000 for owners 65 or older or disabled. Voters approved both increases (Propositions 13 and 11) in November 2025, effective for the 2025 tax year. Counties, cities and special districts may offer their own optional exemptions. How to apply and how much it saves.
- Homestead cap: the taxable value of a homestead cannot rise more than 10% a year, however much the market value grows.
- Protest deadline: May 15, or 30 days after the appraisal notice is delivered if that is later.
- When it's due: bills go out around October; taxes become delinquent if not paid by January 31.
How to lower your property tax in Grayson County
- File for the homestead exemption with your county appraisal district if the home is your primary residence. It removes $140,000 from school district taxable value and caps yearly increases in taxable value at 10%.
- Add the 65+ or disability exemption once you qualify: another $60,000 off school taxable value, and school taxes on the home are frozen at that year's level.
- Protest your appraisal if the value looks high — by May 15 or 30 days after your notice arrives. Comparable sales and photos of needed repairs are the most persuasive evidence.
- Check every taxing unit on your bill. Moving a few streets can change the school district, city or utility district — and the combined rate by several tenths of a percent.
