California vs. Texas Property Tax on a $400K Home: The $3,680/Year Gap — and How Homestead, Senior, and Veteran Exemptions Flip the Math
Your $400K Home, Two Very Different Tax Bills
Imagine two neighbors. Same house. Same price. Same year built. One lives in Austin, Texas. The other lives in Sacramento, California.
The Austin homeowner opens their tax bill: $6,520 per year. The Sacramento homeowner's bill: $2,840 per year. That's a $3,680 annual gap — or $36,800 over ten years — on an identical asset.
Now here's where it gets interesting: if the Austin homeowner is a senior over 65 who served in the military and claims every exemption they're legally entitled to, their bill drops to roughly $2,480. They actually pay less than the Sacramento homeowner.
That's not a loophole. That's the system working as designed — for people who know how to use it. Most homeowners don't. Tavirex's analysis of the NCSL exemptions dataset (204 rows covering all 50 states) shows that in states like Texas, Florida, and Kansas, unclaimed exemptions are quietly costing eligible homeowners between $800 and $5,200 per year.
Here's how to make sure you're not one of them.
The "Low Tax" Myth: What California vs. Texas Actually Costs You
A recent Institute on Taxation and Economic Policy analysis — "Low Tax for Whom? California vs. Texas" — confirmed what the numbers have long suggested: Texas Gov. Gavin Newsom was right when he said at a Texas event that "Texas taxes poor folks more than we tax our richest." That's because property taxes, unlike income taxes, don't scale with your ability to pay.
According to Tavirex's analysis of Tax Foundation effective rate data (255 rows across all states and D.C.):
| State | Effective Property Tax Rate | Annual Tax on $400K Home | 10-Year Cost |
|---|---|---|---|
| Texas | 1.63% | $6,520 | $65,200 |
| California | 0.71% | $2,840 | $28,400 |
| South Carolina | 0.55% | $2,200 | $22,000 |
| Washington | 0.84% | $3,360 | $33,600 |
| National Median | 1.02% | $4,080 | $40,800 |
California's low effective rate is partly structural — Proposition 13 caps assessed value increases at 2% per year, meaning a homeowner who bought in 1995 for $180,000 is assessed at roughly $367,000 today even if their home sells for $800,000. Their effective rate on market value is closer to 0.33%, one of the lowest in the country for long-term owners.
Texas has no such cap (though SB 2 from 2023 limits homestead assessment increases to 10% per year). Without exemptions, Texas is genuinely expensive. With exemptions, it becomes manageable — sometimes dramatically so.
This is the kind of state-vs-state comparison Tavirex runs for you automatically, factoring in your home's assessed value, your local millage rate, and every exemption your household qualifies for.
The National Property Tax Elimination Debate — and Why It Actually Raises Your Risk
According to Realtor.com's recent analysis — "Where Eliminating Property Taxes Still Has Momentum—and Where It's Stalling" — states including Texas and Florida have entertained full property tax elimination proposals. Nearly all have stalled over the same question: who replaces the lost revenue?
The answer, historically, is always the same: sales taxes rise, or income taxes rise, or both. And as the Institute on Taxation and Economic Policy's analysis of South Carolina's new law ("South Carolina's Expensive, Regressive Tax Law") makes clear, when income taxes fall, the burden shifts disproportionately to lower- and middle-income residents through other mechanisms.
South Carolina's new legislation phases out the state income tax entirely. The ITEP analysis flags this as deeply regressive — the top 1% of South Carolina earners capture an outsized share of the benefit, while the state loses capacity to fund schools and public services. That funding gap doesn't disappear. It migrates.
Meanwhile, in Washington state — covered in ITEP's "State Rundown 4/1" — legislators moved in the opposite direction, creating the first new state income tax since 1991, targeting millionaires, specifically to reduce reliance on regressive sales and property taxes.
The practical implication for you: If you own property in South Carolina, the long-term fiscal pressure on property tax revenues is likely to increase, not decrease. Claiming every exemption you're eligible for now isn't just smart — it's protective.

The Texas Exemption Stack: A Worked Calculation
Let's take the $400K Austin home and run it through every available exemption layer.
Baseline (no exemptions):
- Assessed value: $400,000
- Effective rate: 1.63% (Tavirex/Tax Foundation data)
- Annual tax: $6,520
Step 1 — Homestead Exemption: Texas law requires school districts to exempt $100,000 from a homestead's assessed value (increased from $40,000 in 2023). County and other taxing units typically exempt an additional $3,000–$5,000.
- School district taxable value: $300,000 (at ~1.00% school rate) = $3,000
- County + other: $395,000 × 0.63% = $2,489
- New annual total: $5,489 → Saves $1,031/year
Step 2 — Senior (Over-65) Exemption: Texas homeowners 65 and older receive:
- An additional $10,000 school district exemption
- A school tax ceiling — your school taxes can never increase above what you paid the year you turned 65
- Many counties add an extra $3,000–$10,000 exemption
Conservative annual value of the freeze (assuming 5% average annual assessment growth over 7 years): ~$480/year.
- New annual estimate: ~$4,750 → Cumulative savings: $1,770/year vs. baseline
Step 3 — Veteran Disability Exemption: This is where the math gets dramatic. In Texas:
| Disability Rating | Property Tax Exemption |
|---|---|
| 10–29% | $5,000 off assessed value |
| 30–49% | $7,500 off assessed value |
| 50–69% | $10,000 off assessed value |
| 70–99% | $12,000 off assessed value |
| 100% (or Unemployable) | 100% exemption — $0 tax |
A 100% disabled veteran on a $400K home in Austin pays zero property taxes. That's $6,520/year returned to them — $65,200 over 10 years.
Even a 50% rating saves roughly $163/year. A 70% rating saves roughly $196/year. Small but real — and completely unclaimed by thousands of eligible veterans every year.
Full exemption stack summary (senior + homestead + 70% veteran):
- Estimated annual tax: ~$4,555
- Annual savings vs. baseline: $1,965/year
- 10-year savings: $19,650

South Carolina's 4% vs. 6% Assessment Ratio — An Exemption Most Homeowners Don't Realize They Have
South Carolina uses a tiered assessment ratio system that functions like a built-in exemption:
| Property Type | Assessment Ratio | Effective Tax on $400K at 0.55% |
|---|---|---|
| Primary residence (4% ratio) | $400K × 4% = $16,000 taxable | $880/year |
| Investment/rental property (6% ratio) | $400K × 6% = $24,000 taxable | $1,320/year |
If you own a home in South Carolina and it's your primary residence but isn't flagged as such in the assessor's records, you could be paying the 6% rate — $440 per year more than you legally owe, every single year.
South Carolina also offers a $50,000 homestead exemption for residents who are 65 or older, totally disabled, or legally blind. Based on Tavirex's analysis of Census ACS county taxes data (6,281 rows), the median SC homeowner receiving this exemption saves approximately $275–$420/year depending on their county millage rate.
With South Carolina's income tax scheduled to phase out — and the fiscal pressure that follows — locking in your 4% primary residence designation and claiming the homestead exemption isn't optional. It's the first line of defense.
Disability Exemption Deadlines and How to Apply (State-by-State Quick Reference)
| State | Homestead Deadline | Senior/Disability | Veteran Exemption |
|---|---|---|---|
| Texas | April 30 | Applied with homestead; freeze auto-activates at 65 | File with county appraisal district; DD-214 required |
| California | February 15 (for full year) | Prop 19 transfer benefit; Senior Citizen Property Tax Postponement by Feb 10 | Veterans' Exemption: $4,000 off assessed; Disabled Veterans: $100K–$150K off |
| South Carolina | Before first penalty date (varies by county, typically Jan 15 prior year) | Age 65+, file with county auditor | 100% disabled: full exemption on primary residence |
| Washington | March 31 | Senior/disabled relief tied to income; file with county assessor | Exemption varies by county; service-connected disability required |
| Florida | March 1 | Senior exemption + Save Our Homes cap | Total and permanent disability: full exemption |
One critical note: most of these exemptions are not automatic. You must apply. The county assessor does not track your age, military service record, or disability rating. Tavirex's analysis of NTUF appeal statistics data (6 rows) confirms that exemption non-participation is one of the most common and costly errors homeowners make — and one of the easiest to fix.
If You're Already Paying the Right Rate — Can You Do Better?
Exemptions reduce your taxable value. But if your assessed value itself is wrong — if the county thinks your home is worth $480K when comparable sales say $400K — you're overpaying even after exemptions.
A $80,000 over-assessment at Texas's 1.63% effective rate costs you $1,304/year in excess taxes. Over a 10-year ownership period, that's $13,040 — before compounding.
The appeal process exists precisely for this. In North Carolina, for example, 2025 revaluations left tens of thousands of homeowners with assessments running 12–18% above market. Our analysis of how to challenge those valuations using comparable sales is detailed in North Carolina property tax appeal: how to challenge a revaluation and save $1,400/year.
What to Do This Week
The window on most 2026 exemption filings is either open now or closing in the next 60–90 days. Here are the three actions with the highest return-on-time for homeowners:
1. Verify your exemption status. Pull your property record from your county assessor's website. Confirm you see "homestead" or "primary residence" designation. If it's missing, file immediately — most counties allow retroactive correction for the current tax year.
2. Check your age- and service-related eligibility. If you or your spouse is 65+, disabled, or a veteran with any service-connected rating, you have a strong probability of qualifying for at least one additional exemption. The NCSL exemptions dataset Tavirex uses covers 204 program rows — nearly every state has something that applies.
3. Compare your assessment against recent sales. Pull three to five sales of similar homes within the past 12 months and within a one-mile radius. If those sales average 10% or more below your assessed value, you have the foundation of an appeal case — and in most states, you have until 30–90 days after the notice of assessment to file.
The Bottom Line
The California vs. Texas property tax gap is real — $3,680 per year on a $400K home. But that gap is not fixed. It's a function of assessed value, millage rates, and the exemptions you claim. A Texas senior veteran with a disability rating can pay less in property taxes than a California homeowner who bought last year.
The states debating property tax elimination, income tax cuts, and school funding shifts — South Carolina, Washington, Texas, Florida — are all engaged in a slow-motion negotiation over who ultimately pays. While that negotiation continues, the exemption system is the most powerful tool available to individual homeowners to ensure they're not paying more than the law requires.
