Texas $140,000 Homestead Exemption: How Much Your Mortgage Payment Drops in 2026

Texas voters approved raising the state's school district homestead exemption from $100,000 to $140,000 in the November 2025 election — and it is already in effect for the 2026 tax year. This isn't pending legislation. It passed. If you own your primary residence in Texas and filed a homestead exemption with your county appraisal district, your 2026 property tax bill should already reflect the larger deduction. That means your escrow payment is going to drop — the only question is when, and by how much.

I'm Bond Peter Njoku (NMLS #2670329), a mortgage loan officer based in Garland, TX. Property taxes are the escrow component that confuses more Texas homebuyers than any other, and the $140,000 exemption is one of the most meaningful changes to DFW monthly mortgage payments in years. Let me break down the exact dollar amounts by county, how the escrow process works, and what you can do right now to get your payment reduced faster.

How Much Does the $140,000 Homestead Exemption Save by DFW County?

The savings depends on your county's combined effective property tax rate — which includes school district taxes plus city, county, and other local levies. Here's the DFW county-by-county breakdown using the 2026 effective rates:

Note: The above savings represent the full combined tax rate applied to the $140,000 exemption — not just the school tax portion. All taxing entities (school district, city, county, MUD where applicable) recognize the homestead exemption. Over-65 and disabled homeowners receive an additional $60,000 school exemption on top of this, for a total of $200,000, saving $300–$370 per month in escrow depending on county.

What Did the Exemption Raise to From — and What Changed in 2026?

Before November 2025, the state-mandated minimum school district homestead exemption was $100,000 — already increased from $25,000 in 2022. Texas voters approved Proposition 13 in November 2025, raising it to $140,000. At the same time, voters approved increasing the over-65/disabled additional exemption from $10,000 to $60,000, bringing the total for qualifying seniors to $200,000 off taxable school value.

If you already had the exemption before 2026, the incremental change is $40,000 more in deduction — worth about $800 per year in Dallas County and $600 per year in Collin County. That's $50–$67 more per month in escrow savings on top of what you were already saving from the $100,000 exemption. The full $233-per-month savings shown in the first table applies to homeowners who are calculating their total payment from scratch.

How Does the Homestead Exemption Affect My Escrow Payment — and When Does It Change?

Your monthly mortgage payment includes four components: principal, interest, taxes (escrow), and insurance (escrow). Your lender manages the tax and insurance portion by collecting monthly estimates in an escrow account, then paying the bills when they come due. When your property tax bill drops — because of the homestead exemption or any other reason — your lender doesn't automatically reduce your payment the next month. Here's the actual sequence:

1. You file for the homestead exemption with your county appraisal district (Form 50-114) before April 30 of the tax year you want it to apply.
2. The county applies the exemption and generates a lower assessed/taxable value.
3. The county sends tax bills in October or November of the tax year.
4. Your lender receives (or you forward) the updated, lower tax bill.
5. Your lender runs its annual escrow analysis — typically once a year, within 30 days of the loan's anniversary.
6. The analysis shows a projected escrow surplus based on the lower future tax payments.
7. Your payment drops at the next analysis period, and excess escrow may be refunded to you.

Realistic timeline for DFW homeowners: If you filed for the 2026 exemption by April 2026, your county applies it for the October/November 2026 tax bill. If your loan anniversary is in the first half of 2027, your lender's annual escrow analysis will reflect the lower bill and your payment will drop in early-to-mid 2027. That's a 12–18 month lag from the time the law passed to the time your payment changes — which is frustrating but normal.

How to get it faster: You can request an off-cycle "voluntary escrow analysis" from your servicer. Call the customer service number on your mortgage statement and ask them to run an early escrow analysis once the lower tax bill is confirmed. Many servicers will do this, especially if you provide documentation of the reduced tax amount. Some servicers charge a small fee; many don't.

What If You Just Closed on a DFW Home in 2025 or 2026?

If you closed on your primary residence in DFW after January 1, 2025, and you haven't filed for the homestead exemption yet, here's what to do immediately:

• File Form 50-114 with your county appraisal district. It's available on the county CAD website (dallascad.org, collincad.org, dentoncad.com, rockwallcad.com, etc.). The filing deadline for the current tax year is April 30. Late filings can be submitted retroactively for up to two years, but missing a year costs you 12 months of savings.
• You must own the home as your principal residence as of January 1 of the tax year. Buyers who closed on December 1 qualify for the following year's exemption, not the current year.
• You only need to file once. The exemption renews automatically as long as you stay in the home.

Last spring I worked with a Garland buyer who closed in December 2024 on a $335,000 home. She called me in March 2026 confused about why her mortgage payment went up at the first escrow adjustment — it went up because she hadn't filed for homestead yet, so her lender was escrowing based on full assessed value. We walked through the filing process together, she submitted Form 50-114 to Dallas CAD in April 2026, and by February 2027 her lender's escrow analysis will show the $140,000 exemption applied — bringing her escrow payment down by roughly $220 per month. She was already paying about $2,640 extra per year that she didn't need to be paying.
