Property taxes for west FW buyers: the complete playbook

Lever 1: the homestead exemption (file it the week you close)

As of 2026 the mandatory school-district homestead exemption is $140,000 off your taxable value — raised from $100,000 by Proposition 13, approved by voters in November 2025. Homeowners 65+ or disabled get an additional $60,000 (a $200,000 total school exemption) plus a school-tax ceiling. At Aledo ISD's ~1.21% school rate, the standard exemption alone is worth roughly $1,690/year; cities and counties can stack optional exemptions of up to 20% on top.

Filing is free (Form 50-114 with your county appraisal district — Parker or Tarrant, and Walsh straddles both), the deadline is April 30 with a two-year late-filing window, and it renews automatically. It also activates the second benefit people forget: the 10% annual appraisal cap — your homestead's taxable value can't rise more than 10% a year regardless of market value, starting your second year with the exemption. In a corridor appreciating like this one, the cap often outearns the exemption itself.

Lever 2: the protest (free, annual, and it works)

Every spring the appraisal district mails your proposed value; you have until May 15 (or 30 days after the notice, whichever is later) to protest — free, no professional required. The process: file (online in both counties), take the informal review first (many cases settle there), and if needed present to the Appraisal Review Board with evidence — comparable sales, condition photos, repair estimates. New-build buyers have a specific angle: your closing price is evidence, and early assessments in new communities are frequently set from builder list prices that exceed what buyers actually netted after incentives.

Lever 3: know your PID/MUD layer before you sign

Public Improvement Districts and Municipal Utility Districts finance a new community's infrastructure through an additional assessment on top of city, county, and school taxes — and they're why two similar houses can carry very different bills. The corridor's flagship example is Walsh, where the PID runs a millage equivalent of roughly $0.36 per $100 (it doubled from $0.18 in 2026; planning areas 1–3 stayed lower), bringing the total rate to 2.689% — the full dollar math is on the Walsh field notes. Three PID/MUD rules: sellers must disclose district membership, assessments run for set terms (often 15–30 years), and prepayment is often possible — including negotiating builder incentive money toward the payoff, one of the sharpest plays in new construction. Texas law does not apply the homestead exemption to PID assessments the way it does to ad valorem taxes — ask the district how your assessment is structured.

And the year-two trap, one more time: new builds are commonly taxed on land-only value in year one, then reassessed at full improved value — bills jumping 30–50% is normal, not an error. Escrow accordingly from day one. The corridor's base rates live on the rate table; run any purchase through the calculator, which uses them.
