Florida vs Texas vs North Carolina Property Tax on a $400K Home: The $3,080/Year Gap — and What DeSantis's Reform Would Actually Change for Your Bill
Florida vs Texas vs North Carolina Property Tax on a $400K Home: The $3,080/Year Gap — and What DeSantis's Reform Would Actually Change for Your Bill
Picture three families. Each bought a $400,000 home in 2022. One is in Austin, Texas. One is in Tampa, Florida. One is in Raleigh, North Carolina. Same price. Similar house. Completely different property tax reality.
The Austin family pays roughly $6,080 per year in property taxes. The Tampa family pays $4,400. The Raleigh family pays $3,000. That $3,080 annual gap between the highest and lowest adds up to $30,800 over 10 years — money that could be a college tuition payment, a rental property down payment, or simply kept in a savings account.
And right now, all three states are in the middle of policy turbulence that could shift those numbers dramatically. Here's what's happening — and what you should do before the next assessment cycle.
The Side-by-Side: $400K Home, Three States, Three Very Different Bills
| State | Effective Rate | Annual Tax (No Exemptions) | With Standard Exemption | 10-Year Cost |
|---|---|---|---|---|
| Texas (Travis County) | 1.74% | $6,960 | $6,080 (homestead $40K deduction) | $60,800 |
| Florida (Hillsborough County) | 1.10% | $4,400 | $3,850 (homestead $50K deduction) | $38,500 |
| North Carolina (Wake County) | 0.75% | $3,000 | $3,000 (no flat deduction) | $30,000 |
Note: These figures use current effective rates from state tax data. Your individual bill depends on the specific millage levied by your school district, county, and any special districts — and critically, whether your assessment actually reflects market value.
This is the kind of analysis Tavirex runs for your specific address — pulling actual millage components and comparing your assessed value against recent comparable sales in your zip code.
Florida: The "$55 Billion Gusher" and What DeSantis Is Actually Proposing
Florida's property tax revenue grew from $31 billion to $55 billion in just five years, according to a Realtor.com report on Governor DeSantis's recent proposal. DeSantis called it a "gusher" and floated the idea of eliminating property taxes on primary residences entirely — describing it as now "doable" given the revenue surge.
Here's the math on what that would mean for a Tampa homeowner:
Current Tampa/Hillsborough scenario on a $400K home:
- Assessed value: $400,000
- Homestead exemption: -$50,000
- Taxable value: $350,000
- Millage rate (county + school + special districts): ~12.0 per $1,000
- Annual bill: approximately $4,200
If the homestead exemption were eliminated entirely (not just the standard $50K deduction, but all property tax on primary residences), that family saves $4,200 per year — $42,000 over 10 years.
The catch? DeSantis has proposed funding the gap by taxing foreign real estate buyers — specifically calling out "rich guys from Brazil." That's a politically loaded framing, but the policy math is genuinely difficult. Florida local governments depend heavily on property tax revenue to fund schools, roads, and emergency services. Eliminating it for primary residences requires either cutting services or replacing the revenue from somewhere else.
For Florida homeowners right now: the reform is speculative. What isn't speculative is that your Florida bill is already composed of multiple millage layers — school district, county general fund, municipal services, and special districts like water management and hospital authority. Understanding which layer is driving your bill is step one in any appeal or exemption strategy. For a full millage breakdown, see our Florida property tax deep-dive.
Texas: High Rates, High Stakes, and the Inherited Property Trap
Texas has no state income tax, which sounds like a win — until your property tax bill arrives. The effective rate in most urban Texas counties runs 1.5% to 2.0%, among the highest in the country. And because Texas schools are heavily funded through property levies, the school millage component alone can exceed 1.0 per $100 of assessed value.
The brutal edge case: what happens when you inherit a Texas home.
A Realtor.com story followed a family that inherited a home in East Austin after a family member passed away. The result was a $48,000 property tax bill — not because the tax rate changed, but because the inherited home lost three stacked exemptions simultaneously: the homestead exemption, an over-65 freeze, and a disability exemption. Without those protections, the assessed value reset to current market value in one of the hottest zip codes in the country.
The math on that Austin inheritance scenario:
- Inherited home, appraised at $620,000 (East Austin market)
- Lost homestead: +$40,000 to taxable base
- Lost over-65 freeze: assessment unfrozen, jumps $180,000
- Lost disability exemption: another $10,000 to taxable base
- Effective taxable value increase: ~$230,000
- At Travis County's blended rate of ~2.1%: +$4,830/year
- Back taxes and catch-up assessments: total bill climbs to ~$48,000

North Carolina: A Decade of Tax Cuts — and an Assessment Ratio Problem Nobody Talks About
North Carolina has the lowest effective rate of our three states at roughly 0.75% — but a Tax Foundation analysis of "Avenues for Property Tax Reform in North Carolina" flags something that trips up homeowners who think they're getting a good deal: assessment ratios that drift significantly from market value between revaluation cycles.
North Carolina counties revalue property on a 4-to-8-year cycle (some counties are even longer). If your county last revalued in 2019 and your neighborhood appreciated 40% since then, your assessment may lag — or it may have overcorrected in the other direction during the 2024 revaluation. The Tax Foundation notes that restoring balance in assessments "without distorting investment or shifting costs unfairly" is the central challenge.
Here's the hidden cost of an off-ratio assessment:
Worked example — Wake County, Raleigh:
- Your home's market value: $400,000
- Your assessed value: $460,000 (assessed at 115% of market — not unusual after aggressive revaluation)
- Wake County rate: 0.7207 per $100
- School levy: ~0.70 per $100
- Total millage: ~$14.41 per $1,000
- Annual tax on $460K assessment: $6,629
- What you should pay on $400K: $5,764
- Overpayment: $865/year, $8,650 over 10 years
Meanwhile, your neighbor whose identical house was assessed at $380,000 (95% of market) pays $5,476 — $1,153 less than you, every single year, for the same house on the same street.
That gap is 100% fixable through a formal appeal using comparable sales. The Institute on Taxation and Economic Policy's state rundown for March 26, 2025 noted that North Carolina's decade of tax cuts — including corporate rate reductions — is now creating "sobering revenue projections" for lawmakers. That fiscal pressure means assessors are under pressure to maximize assessed values, which makes this an especially important moment to verify your assessment ratio is accurate.

The Action Framework: What to Do in the Next 30 Days Depending on Your State
If you're in Texas:
- Log in to your county appraisal district (HCAD for Houston, TCAD for Austin) and pull your notice of appraised value
- Check whether all applicable exemptions are filed: homestead, over-65, veteran, disability
- Protest deadline is typically May 15 or 30 days after your notice — whichever is later
- Pull 3-5 comparable sales from the last 12 months within 1 mile and 200 square feet of your home's size
If you're in Florida:
- Check your TRIM notice (Truth in Millage) — mailed in August, but you can pull current assessment now through your county property appraiser's website
- Verify your homestead exemption is applied (especially if you moved, refinanced, or inherited)
- Appeal deadline is 25 days after TRIM notice mailing — one of the shortest windows in the country
- The Save Our Homes cap limits annual assessment increases to 3% for homestead properties — if you've owned for 5+ years and your assessment jumped more than 3%, that's a red flag
If you're in North Carolina:
- Find your county's last revaluation date — if it was 2023-2024, your assessment may be at or near peak
- Request your property record card from the county assessor (it's public record and usually free)
- Compare your assessed value per square foot to recent sales in your neighborhood
- Appeal window varies by county but is typically 30-90 days after revaluation notices are mailed
The Worked Savings Calculation: What a Successful Appeal Is Actually Worth
Let's say you're in Tampa and you successfully get your assessed value reduced from $420,000 to $370,000 — a $50,000 reduction that correctly reflects comparable sales.
- Tax reduction: $50,000 × 1.20% effective rate = $600/year
- Over 5 years of remaining ownership: $3,000
- Over 10 years: $6,000
- If you model this at a 5% discount rate (opportunity cost of that money): net present value of ~$4,630
That's not a small number. And that's a modest appeal in a mid-tier Florida county. In a high-value Texas county, a $100,000 assessment reduction at a 1.8% effective rate saves $1,800/year — $14,220 in NPV terms over 10 years.
Tavirex can model this for your specific address, assessment, and county rate — so you know before you file whether an appeal is worth your time.
The Bottom Line: Three States, Three Strategies
| State | Biggest Lever | Urgency | Estimated Annual Savings |
|---|---|---|---|
| Texas | Verify all exemptions, protest by May 15 | High (short window) | $800–$3,200 |
| Florida | Homestead exemption + TRIM appeal within 25 days | Medium (window is tight) | $600–$2,400 |
| North Carolina | Check assessment ratio against comparable sales at next revaluation | High if recently revalued | $400–$1,800 |
The three-state gap in our $400K home scenario — $3,080/year between Texas and North Carolina — is partly structural. You can't change where you live with a form submission. But the portion driven by incorrect assessments, missing exemptions, or inflated millage allocations? That part is fixable. And the clock is usually ticking.
For a broader state-by-state rate comparison including New Jersey, Pennsylvania, and Illinois, see this multi-state analysis on a $400K home. The gaps are even larger when you bring the Northeast into the picture.
Start with your current assessment. Pull the comparable sales. Run the numbers at Tavirex before your appeal window closes.
