How Property Taxes Actually Work in the Rio Grande Valley

Here's a number that should bother you if you own property in Hidalgo County: in the last mass reappraisal, residential values across the county went up an average of 17.9%. In that same window, actual home sale prices in the McAllen metro area fell about 6.1%. Values went up. Real sale prices went down. Those two numbers should never move in opposite directions this far apart, and when they do, it usually means one thing — a lot of properties got overvalued.

An outside analysis of the 2025 reassessment found that roughly 39% of homes in the county were overvalued relative to what they'd actually sold for. That's not a rounding error. That's a huge share of Hidalgo County homeowners paying tax on a number that doesn't reflect their home's real value — and most of them never protest it.

How your tax bill actually gets built

It's a simpler process than people assume, once you break it into steps:

1. The Hidalgo County Appraisal District (HCAD) sets your property's market value as of January 1 every year — what it estimates the property would sell for on the open market.
2. Your exemptions get subtracted from that market value to arrive at your taxable value — homestead, over-65, disability, and a few others.
3. Every taxing entity that overlaps your property sets its own rate — your school district, the county, your city, and any special districts — and those rates get added together into one combined rate.
4. Your taxable value multiplied by that combined rate is your bill.

Texas doesn't have a state income tax, so property taxes carry more of the load here than in most states. That's exactly why understanding this process, and protesting when the numbers don't line up, actually matters in a way it might not somewhere else.

The homestead exemption just got a lot bigger for 2026

If you haven't looked at this in a couple of years, pay attention: under SB 4, the school district homestead exemption jumped from $100,000 to $140,000 for 2026. If you're over 65 or disabled, you get an additional $60,000 on top of that — up to $200,000 in combined school exemption. Disabled veterans with a 100% service-connected disability pay zero property tax on their primary residence.

There's also a 10% annual cap on how much your appraised value can increase each year on a homestead property, regardless of what the market does. That cap is valuable, but it only protects your appraised value — the appraisal district can still set a much higher market value on paper, and if you ever sell, that inflated market value becomes the new owner's starting point. That's part of why protesting the underlying market value matters even when the cap is protecting your bill in the short term.

Why this year is different in Hidalgo County

Between the 17.9% average value increase and the 6.1% actual decline in sale prices, a record number of Hidalgo County property owners are protesting — 66,476 protests filed, up from 55,580 the year before. And when people do protest with real evidence, it works: Hidalgo County's Appraisal Review Board has sided with property owners in about 69% of recent appeals.

Worth knowing: HCAD doesn't send a notice every year to every property. If your value didn't go up by at least $1,000, you may not get a letter at all — which doesn't mean your value is fine, it just means nobody's telling you to check.

The deadline

Mark this down: May 15, or 30 days after your Notice of Appraised Value was mailed, whichever is later. Miss it, and you're stuck with whatever value HCAD assigned for the entire year. Applications for exemptions you haven't claimed yet are generally due by April 30 — so if you bought a home recently and never filed for your homestead exemption, that's free money you're currently leaving on the table.

What I actually do for clients on this

I protest my own family's properties every year, so I'm not telling anyone to do something I don't do myself. We've gotten real reductions — some small, some very large, depending on the property and the evidence available.

Here's how I work with people who reach out about this: if you want to fight your own protest, I'll help prepare your comps for free. No charge, no catch — I'll pull the comparable sales you need to make a real case in front of the appraisal review board. If you'd rather not deal with the process yourself, we also run an in-house property tax protest service on a 25% contingency fee — you only pay if we actually save you money. If we don't get a reduction, you don't owe us anything.

Either way, the time to act is now. Schedule this in March or April, not May — the deadline doesn't move, and once it passes, there's nothing anyone can do for you until next year. Call or text me at 956-212-5351, or email diego@forsalergv.com, and let's make sure you're not paying more than you should be.
