Northlake has some of the newest housing in Denton County. Denton CAD's 2026 roll lists 4,910 single-family homes with a Northlake address, at a median market value of $557,000 and $199 per square foot. About 61% of them, 3,009 homes, were built in 2021 or later.
New homes mean first-year appraisals and builder-priced comps, and more chances for a value to land too high. Owners can protest each spring. The usual deadline is May 15 or 30 days after your notice, whichever is later.
TaxDrop's TDLR-licensed Texas consultants can handle the protest for you, from filing through the Appraisal Review Board hearing. See TaxDrop pricing for current plans.
Your Northlake tax bill is several separate taxes added together. Each taxing unit sets its own rate per $100 of taxable value (Denton County Tax Office, 2026 adopted rates; Town of Northlake):
Watch for special districts. Many newer Northlake subdivisions sit in districts that add their own rate on top of the town, county and school taxes. A protest lowers your value, which lowers every rate-based tax on it. Check the taxing units on your notice.
Homestead exemption: Texas school districts must exempt $140,000 of a homestead's value, plus another $60,000 for owners 65 or older or disabled (Texas Comptroller). On Northwest ISD's rate, the $140,000 exemption cuts about $1,490 a year off the school portion. Homestead appraisal increases are capped at 10% a year, plus new improvements.
Northlake is home to 8,283 people (Census ACS 2020β2024). Where you live matters here. The combined 2026 rate runs from 1.54% in Northwest ISD to 1.63% in Argyle ISD. On the median $565,600 home, that gap is worth about $520 a year before exemptions.
All of Northlake is in Denton County, so Denton Central Appraisal District (Denton CAD) appraises your home.
