Should you protest your property tax appraisal on a new-construction home?

Yes, in most cases, and the best time to start is the first year you own the home. Denton County's protest deadline is May 15, or 30 days after your Notice of Appraised Value is mailed, whichever is later. New-construction homes are especially prone to overvaluation because the appraisal district often leans on builder base pricing rather than resale comps, and roughly 70% of Texas homeowners who protest receive some reduction.

Move-up families closing on new construction in Furst Ranch, Whyburn, or Harvest tend to focus on the closing itself and forget that the appraisal fight is a separate, recurring event. Then the second-year tax bill lands, well above what they budgeted, and the scramble starts.

Here's how to get ahead of it instead.

Why New Construction Gets Hit Harder Than Resale

Denton CAD assesses your home based on what existed on the property as of January 1 each year. If your home wasn't finished by January 1, you get a lighter land-plus-partial-structure assessment for that first year. Once the home is complete and occupied, the following year's appraisal reflects full value, and that's the number that surprises people.

New-construction neighborhoods are also especially prone to overvaluation because appraisal districts often lean on builder base pricing for comps, rather than resale sales data. If a builder in your section is selling homes at $750,000, the district may appraise your home closer to that number even if your specific lot, orientation, or finish-out doesn't match what's currently selling. That gap is one of the most common and most winnable protest scenarios in Denton County.

The Deadline You Actually Need to Track

For most Denton County homeowners, the protest deadline is May 15, or 30 days after your Notice of Appraised Value is mailed, whichever is later. Denton CAD typically mails notices in mid-April, which gives new owners a real but narrow multi-week window to act.

If you closed partway through the year, don't assume you missed your shot. The 30-day-after-notice window exists specifically for situations like a new owner receiving their first notice outside the standard mailing cycle.

What to Do in Year One

Protesting in your first year sets a lower baseline, since every future appraisal builds off that starting point. A few things worth doing before you file:

• Pull comparable resale sales, not builder pricing, for homes similar in size, lot, and condition to yours. This is the core evidence in most successful protests.
• Document anything that affects value the appraisal district wouldn't know about, like a smaller usable lot, an unfinished landscaping package, or a floor plan that differs from your section's typical listing.
• File before the deadline even if you're still gathering evidence. You can supplement your protest later, but missing the filing window forfeits the year entirely.
• Confirm your homestead exemption is filed and applied, separately from the protest itself. The Texas school homestead exemption is $140,000 for the 2025 tax year, and it doesn't apply automatically. You still owe your taxes by the deadline while a protest is pending, though a successful protest results in a refund of any overpayment.

What Happens If You Wait

The math compounds against you. Every year you don't protest, the appraisal district's number becomes the new baseline for the following year's increase calculations. A first-year appraisal that's high by $50,000 doesn't just cost you one year of extra tax. It becomes the floor the district builds from going forward, unless you correct it.

This is exactly the kind of detail that gets lost in the excitement of closing on a new build in Furst Ranch or Whyburn, and it's worth a five-minute conversation with your agent well before next April, not after the notice arrives.

If your MUD tax situation is also part of your total cost picture, this breakdown of what MUD taxes actually add to a Furst Ranch payment is worth reading alongside your appraisal protest planning, since both affect your real annual number.

Frequently Asked Questions

Do I have to pay my property taxes while my protest is pending?

Yes. You're still responsible for paying by the deadline to avoid penalties, even with an active protest. If your protest succeeds, any overpayment is refunded.

What evidence works best in a new-construction protest?

Comparable resale sales for similar homes in size, lot, and condition tend to carry the most weight, since appraisal districts often lean on builder base pricing rather than resale comps for brand-new sections, which can inflate the assessed value relative to what's actually selling.

Is it worth protesting every single year, or just the first year?

The first year matters most because it sets your baseline, but protesting is worth considering most years, since appraised values tend to rise annually and each year's number builds on the last.

What's the deadline to protest in Denton County?

May 15, or 30 days after your Notice of Appraised Value is mailed, whichever is later. Notices typically go out in mid-April.

Does a successful protest lower my taxes permanently?

Not permanently, but it resets your baseline lower for future appraisals. Since each year's increase is calculated off the prior year's appraised value, a lower starting point compounds in your favor over time.
