A homeowner in Cedar Park typically pays a combined property tax rate of roughly $2.01 per $100 of taxable value, with the exact figure depending on which overlapping jurisdictions cover the address. The City of Cedar Park’s own levy makes up only about 18 percent of that total; the school district takes the largest share by far.1City of Cedar Park. Frequently Asked Questions Your bill comes from several independent taxing entities stacked together, and your ability to lower it depends mostly on exemptions and, if your appraisal looks high, a timely protest.
What Makes Up the Combined Rate
No single government sets your Cedar Park property tax. Each entity below adopts its own rate, and your bill is the sum of all rates that apply to your parcel.
- City of Cedar Park: $0.3630 per $100 of taxable value.2City of Cedar Park. Frequently Asked Questions – Property Tax Rate
- Leander ISD: $1.0869 per $100, split between $0.7569 for maintenance and operations and $0.3300 for debt service. Most Cedar Park addresses fall inside Leander ISD boundaries.3Leander ISD. Financial Transparency

How to Calculate What You’ll Owe
Property values are set by the Williamson Central Appraisal District (WCAD) for parcels in Williamson County and by the Travis Central Appraisal District on the Travis County side.1City of Cedar Park. Frequently Asked Questions Texas law requires appraisal districts to value property at 100 percent of market value as of January 1 each year, using recent sales of comparable homes as the benchmark.6Williamson Central Appraisal District. Notice of Appraised Value Explained If you have an active homestead exemption, there’s also a legal cap: the appraised value used for your bill can’t rise more than 10 percent above the prior year’s figure, plus the value of any new improvements.7Texas Comptroller of Public Accounts. Valuing Property – Section: Limitation on Residence Homestead Value Increases
The math itself is simple. Divide your taxable value by 100, then multiply by the rate. On a home with a taxable value of $400,000 at the combined rate of about $2.01, that’s 4,000 × $2.01 = $8,040 for the year. The city’s share would be 4,000 × $0.3630 = $1,452, and Leander ISD’s share would be 4,000 × $1.0869 = $4,348.
One thing complicates the arithmetic: your taxable value isn’t the same for every entity. The $140,000 school homestead exemption only reduces the number Leander ISD uses, not the figures used by the city or county. The final consolidated bill rolls each entity’s separate calculation into a single statement.
Exemptions That Lower Your Bill
Exemptions are the single most effective way to reduce what you pay. Every homeowner who occupies the property as a primary residence can file for a residence homestead exemption with the appraisal district in the county where the property sits — WCAD for Williamson County. The application deadline is before May 1 of the tax year, though late applications are accepted for up to two years after the delinquency date.8Texas Comptroller of Public Accounts. Property Tax Exemptions
General Residence Homestead
The biggest dollar-for-dollar reduction comes from the school district exemption. Texas law requires school districts to exempt $140,000 from the appraised value of a qualifying home.9State of Texas. Texas Tax Code 11.13 – Residence Homestead On a home appraised at $500,000, Leander ISD would apply its rate to $360,000 instead of the full amount, saving roughly $1,522 per year at the current school rate. You’ll need a Texas driver’s license or state ID showing the property address to qualify.10Williamson Central Appraisal District. Exemptions Information and Requirements Local entities such as the city and county may adopt their own optional percentage-based homestead exemptions of up to 20 percent of appraised value.
Over-65 and Disabled Homeowners
If you are 65 or older or have a qualifying disability, you receive an additional $60,000 school-district exemption on top of the standard $140,000, for a total of $200,000 off the appraised value for school tax purposes.9State of Texas. Texas Tax Code 11.13 – Residence Homestead More valuable still is the tax ceiling that comes with it: once you qualify, your school district tax amount is frozen. Whatever you pay to Leander ISD in your qualifying year becomes the most you’ll ever owe that district, even if values and rates rise later. Other taxing entities may adopt their own optional over-65 or disability exemptions.
Disabled Veterans
Veterans with a service-connected disability qualify for an exemption based on their rating, from $5,000 off the property’s value for a 10–29 percent rating up to $12,000 for a 70–100 percent rating.11Texas Comptroller of Public Accounts. Disabled Veteran and Surviving Spouse Exemptions Frequently Asked Questions Veterans rated 100 percent disabled may qualify for a full exemption on their homestead. An official VA award letter showing the disability rating is required at filing.12Texas Veterans Commission. Property Tax Exemptions Available to Veterans Per Disability Rating
Protesting Your Appraisal
If WCAD’s value on your Notice of Appraised Value looks too high, you can protest at no cost. The deadline is May 15 or 30 days after the notice was mailed, whichever is later.13Texas Comptroller of Public Accounts. Appraisal Protests and Appeals Miss it and you forfeit the right to challenge the value for that year.
Most protests are resolved informally. You meet with a staff appraiser and present comparable sales from similar homes nearby, photos of condition issues, repair estimates, or an independent appraisal. If that doesn’t produce agreement, your case moves to the Appraisal Review Board, a citizen panel that hears both sides and issues a binding decision for the tax year. From there, an unfavorable ruling can be appealed to the state district court in the county where the property is located. Property tax consultants will handle the whole process on a contingency basis, commonly charging 20 to 50 percent of the first year’s tax savings.
Paying the Bill
Tax bills go out in October and are due by January 31 of the following year.14Texas Comptroller of Public Accounts. Paying Your Taxes Williamson County accepts online payments by eCheck at no extra cost or by credit and debit card with a 2.15 percent convenience fee. Online payments made by 11:59 p.m. Central Time on January 31 are timely. If you mail close to the deadline, send certified so you have proof of the postmark.15Williamson County, TX. Payment Options
Partial payments are accepted, but paying less than the full amount doesn’t stop the remaining balance from becoming delinquent on February 1. Penalties and interest accrue only on the unpaid portion.15Williamson County, TX. Payment Options
Installment Option for Seniors and Disabled Homeowners
Homeowners who qualify for the over-65 or disabled-person homestead exemption can split the bill into four equal installments without penalty. The first payment is due before February 1, the next three before April 1, June 1, and August 1.16Texas Comptroller of Public Accounts. Payment Options You must submit written notice of your intent to pay in installments with the first payment. Missing any installment deadline makes the unpaid portion delinquent with a 6 percent penalty and 1 percent monthly interest.
What Late Payment Costs
Taxes unpaid on February 1 are delinquent, and the charges mount quickly. A 6 percent penalty plus 1 percent interest hits on February 1. Each month through June adds another 1 percent penalty and 1 percent interest. On July 1, the penalty jumps to 12 percent regardless of how many months have passed, and interest keeps accruing at 1 percent per month with no cap.14Texas Comptroller of Public Accounts. Paying Your Taxes
Once a delinquent account is referred to a collections attorney, which can happen as early as July, an additional penalty of up to 20 percent may be added to cover legal fees. By year’s end, accumulated penalties, interest, and attorney fees can inflate the original bill by 45 to 50 percent. Every taxing entity holds an automatic tax lien on your property that attaches on January 1 each year, and that lien gives the courts the power to foreclose and auction the property to satisfy unpaid taxes.14Texas Comptroller of Public Accounts.
