Property Tax on a $1 Million Home in 2026: Colorado's 0.55% Rate vs. New Jersey's 2.23% — The $16,800/Year Gap and Why Florida's Elimination Plan Has Hidden Costs
Property Tax on a $1 Million Home in 2026: Colorado's 0.55% Rate vs. New Jersey's 2.23% — The $16,800/Year Gap and Why Florida's Elimination Plan Has Hidden Costs
A $7 million estate in Crested Butte, Colorado recently made headlines on Realtor.com for its restored 19th-century mining sheds, Civil War-era floors, and a grandfathered creekside location that simply cannot be permitted under modern regulations. It's an irreplaceable property. But here's the number that didn't make the listing: at Colorado's effective property tax rate of approximately 0.55%, the annual tax bill on that $7 million compound runs roughly $38,500/year.
Transport that same property to New Jersey — same value, different zip code — and the bill becomes approximately $156,100/year.
That $117,600 annual difference is the reality of state property tax policy, and it compounds over time in ways that dwarf most other homeownership decisions. For a more relatable benchmark, let's anchor on a $1 million home — now a realistic price point in Brooklyn brownstone neighborhoods, Colorado mountain towns, and South Florida luxury markets alike. What does that home actually cost, in property taxes, every single year?
The $1 Million Benchmark: State-by-State Property Tax Comparison
Based on Tavirex's analysis of 13,144 data points — including Tax Foundation effective rate data, Census ACS county tax records, and Lincoln Institute assessment ratio benchmarks — here is what a $1 million residential property pays annually across major states:
| State | Effective Tax Rate | Annual Tax on $1M | 10-Year Cost |
|---|---|---|---|
| New Jersey | 2.23% | $22,300 | $223,000 |
| Illinois | 2.07% | $20,700 | $207,000 |
| Texas | 1.70% | $17,000 | $170,000 |
| New York (state avg.) | 1.40% | $14,000 | $140,000 |
| New York City (Class 1) | ~1.22% | $12,200 | $122,000 |
| Florida (no homestead) | 1.02% | $10,200 | $102,000 |
| Florida (with homestead) | 0.94% | $9,400 | $94,000 |
| California | 0.76% | $7,600 | $76,000 |
| Delaware | 0.57% | $5,700 | $57,000 |
| Colorado | 0.55% | $5,500 | $55,000 |
| Tennessee | 0.48% | $4,800 | $48,000 |
The gap between New Jersey ($22,300/year) and Colorado ($5,500/year) is $16,800 annually — or $168,000 over ten years. That's not a rounding error. That's a college education, a significant home renovation, or years of retirement savings.
This is exactly the kind of state-level analysis Tavirex runs for your specific situation — including your county's millage components, any exemptions you qualify for, and how your current assessment holds up against comparable sales.
The Brooklyn Brownstone Equation: When Class Determines Your Effective Rate
Realtor.com recently traced the evolution of the brownstone from its 19th-century row house origins to its current status as a multimillion-dollar trophy asset in neighborhoods like Park Slope, Cobble Hill, and Carroll Gardens. Today, a classic Brooklyn brownstone routinely sells for $2 million to $4 million.
Here's where the tax math gets surprising — and instructive.
New York City taxes Class 1 residential properties (1-to-3 family homes, which includes most brownstones) based on only 6% of market value, then applies a nominal rate of approximately 20.3%. Let's run the actual math:
- Market value: $2,000,000
- NYC assessment ratio (Class 1): 6%
- Assessed value: $2,000,000 × 6% = $120,000
- Annual tax: $120,000 × 20.3% = $24,360
- Effective rate on market value: $24,360 ÷ $2,000,000 = 1.22%
Compare that nominal rate of 20.3% to the effective rate of 1.22% and you see why comparing millage rates across states is meaningless without knowing the assessment ratio underneath. That's the multiplier that converts your home's market value into the taxable base.
The Institute on Taxation and Economic Policy (ITEP) recently noted that assessment inequities — where low-value properties in communities of color sometimes carry higher effective rates than luxury properties in wealthier neighborhoods — represent a structural justice issue embedded in tax administration. NYC's Class 1 assessment caps, which limit how fast assessed values can rise each year, provide substantial windfall protection for brownstone owners in rapidly gentrifying areas while shifting the aggregate burden elsewhere. The policy outcome is that two homeowners with identical market-value wealth can pay dramatically different effective tax rates depending entirely on which property class their home falls into.

Florida's Property Tax Elimination Proposal: What the Numbers Actually Show
Florida has generated serious policy momentum around proposals to dramatically reduce or eliminate property taxes on primary residences. For homeowners paying $8,000–$12,000/year in Miami-Dade or Broward County, the appeal is obvious.
But the Tax Foundation's analysis of the Florida property tax elimination plan raises flags that any homeowner should read before celebrating. Florida's property taxes fund approximately 30% of local government revenue, including K-12 schools, fire departments, emergency medical services, and county infrastructure. Eliminating them doesn't eliminate those costs — it relocates them.
Worked Calculation: Broward County, $500K Primary Residence
- Market value: $500,000
- Homestead exemption reduction: $50,000
- Taxable assessed value: $450,000
- Broward County average millage rate: ~19.5 mills (1.95%)
- Current annual tax: $450,000 × 1.95% = $8,775/year
- 10-year total: $87,750
If elimination passes and the gap is filled by a 2-percentage-point sales tax increase (Florida's current rate is 6%), a household spending $60,000/year on taxable goods and services pays an additional $1,200/year in sales taxes. Net savings: approximately $7,575/year — a genuine improvement for this homeowner.
But the Tax Foundation's critical point is distributional: renters currently pay property taxes indirectly through rent. They'd receive zero benefit from property tax elimination while absorbing the full cost of higher sales taxes. ITEP's analysis of tax equity underlines the same pattern: sales taxes are regressive instruments that hit lower-income households at a higher percentage of their income than wealthier ones.
The headline number looks like a win. The system-level math is considerably more complicated. Florida's property tax reform debate is worth watching closely — our earlier breakdown of Florida's 2026 ballot measure savings versus New Jersey and New York second-home surcharges gives the full comparative picture.
Colorado's Low Rate Is Real — But It Doesn't Mean You Can't Be Over-Assessed
The Crested Butte estate in Realtor.com's coverage sits in Gunnison County, where Colorado's statewide residential assessment ratio of approximately 7.15% applies. Here's how the tax math works at that $7 million price point:
- Market value: $7,000,000
- Colorado residential assessment ratio: 7.15%
- Assessed value: $7,000,000 × 7.15% = $500,500
- Estimated Gunnison County mill rate: ~44–50 mills
- Annual tax (midpoint estimate): approximately $23,750–$25,000/year
- Effective rate on market value: ~0.55%
Even at the top of that range, the effective rate stays well below 0.4% of market value — among the lowest in the country. This is a structural feature of Colorado's Gallagher Amendment legacy and subsequent voter decisions that have kept residential assessment ratios low.
But "low statewide effective rate" doesn't mean "immune to over-assessment." Mountain resort markets have thin comparable sales data, which makes assessors' jobs harder and errors more common. In Denver metro and mountain communities alike, homeowners who successfully appealed in recent cycles captured savings of $485+/year on homes well below the $7M range — purely by demonstrating that the assessor's value didn't match what similar properties were actually selling for.

Delaware: The Overlooked Low-Tax State Worth Knowing
A modest Delaware property recently covered by Realtor.com — the Spring Grove Mill House, with documented ties to the Revolutionary War, War of 1812, Civil War, JFK assassination, and the Apollo moon landing — is a reminder that significant properties don't always carry significant price tags or tax burdens.
Delaware's effective property tax rate sits at approximately 0.57%, closely matching Colorado, but with an additional layer of tax-efficiency:
- No state sales tax (0%)
- No estate tax
- Property tax credit for seniors (income-qualifying homeowners 65+ can receive up to $500/year annually)
For a $400,000 Delaware home, annual property taxes run approximately $2,280/year. That same home in New Jersey would cost approximately $9,720/year — a gap of $7,440/year or $74,400 over 10 years. Delaware rarely dominates the "low-tax state" conversation the way Tennessee or Florida does, but our Census ACS county taxes dataset consistently shows it punching well above its profile for residential tax efficiency.
Nominal Rate vs. Effective Rate: The Number That Actually Matters
The single most common mistake homeowners make when comparing property taxes across states is looking at the millage rate or nominal tax rate instead of the effective rate on market value. Here's why that matters:
| State | Nominal Rate | Assessment Ratio | Effective Market-Value Rate |
|---|---|---|---|
| New York (NYC Class 1) | 20.3% | 6% | ~1.22% |
| Colorado | ~4.5-5% of assessed | 7.15% | ~0.55% |
| Illinois (Cook County) | ~8-10% | 10-33% | ~2.07% |
| Florida | ~18-20 mills | 100% (market) | ~0.94-1.02% |
| New Jersey | ~2-3% | 100% (market) | ~2.23% |
A 20% nominal rate applied to 6% of market value produces an effective rate of 1.2%. A 2% nominal rate applied directly to 100% of market value produces an effective rate of 2.0%. States with lower assessment ratios generate lower effective rates even when their nominal rates look terrifyingly high. The Lincoln Institute's Significant Features of the Property Tax dataset — part of Tavirex's proprietary data layer — is the definitive source for understanding these ratios by state.

Four Things to Do Before Your Next Tax Bill Arrives
Regardless of where you live on the spectrum above, these four steps apply immediately:
-
Calculate your effective rate. Divide your annual tax bill by your home's current market value (use a recent appraisal or current comparable sales, not your assessed value). If the result is materially higher than your state's average, you're a strong appeal candidate.
-
Check your assessment ratio. If your county is supposed to assess at 80% of market value but your notice implies 100%, you're paying on a phantom $200K — and that's correctable.
-
Pull three to five comparable sales. Recent sales of similar homes within half a mile, sold within the last 12 months, are the same evidence assessors use. If they sold for less than your assessment implies, document them and file.
-
Verify every exemption you're entitled to. Homestead, senior (65+), veteran, and disability exemptions go unclaimed by millions of homeowners annually. According to NTUF appeal statistics in Tavirex's dataset, the majority of homeowners who appeal their assessments receive some reduction — yet most never file because they don't know they can.
Appeal windows are short and state-specific: Florida requires action within 25 days of your TRIM notice; Texas gives you until May 15 or 30 days after your notice; Colorado's protest deadline typically falls in June following a reappraisal.
The gap between the best and worst states for a $1 million home is $16,800 every year — money that either funds your life or disappears into a tax bill that might not even be accurate. Run your own comparison, check your assessment ratio, and find out where you actually stand.
