Research question
How much does effective property tax vary by state, and what does that spread cost on the same $400,000 home per year?
Dataset
- Effective property-tax rate (%) for all 50 states — TruePITI market dataset (ATTOM 2026 + Census basis).
- A constant $400,000 home value to isolate the tax rate.
Methodology
- Effective rate = total property tax ÷ home value, as published per state.
- Rank states by effective rate; annual tax on $400k = 400,000 × rate.
- Compare the highest and lowest states to express the spread as a ratio.
Calculations
| State (highest 10) | Effective rate | Annual tax on $400k |
|---|---|---|
| New Jersey | 2.49% | $9,960 |
| Illinois | 2.27% | $9,080 |
| New Hampshire | 2.18% | $8,720 |
| Connecticut | 2.14% | $8,560 |
| Vermont | 1.9% | $7,600 |
| Texas | 1.8% | $7,200 |
| Wisconsin | 1.76% | $7,040 |
| Nebraska | 1.73% | $6,920 |
| New York | 1.72% | $6,880 |
| Rhode Island | 1.63% | $6,520 |
Effective rates reflect statewide averages; county-level rates differ and shift with reassessment cycles.

Findings
- The highest-rate state (New Jersey, 2.49%) charges about 8.9× the annual tax of the lowest-rate state (Hawaii, 0.28%) on the same $400,000 home — roughly $8,840 per year.
- Property tax is a recurring, appreciating-rate cost — unlike a one-time closing cost, it compounds with home value.
- Because the escrow is monthly, the tax spread shows up directly in the PITI payment.
Limitations
- State averages hide large intra-state county variation.
- Homestead exemptions, assessment caps and appeal outcomes change the effective rate for individual owners.
- Rates are dated; reassessments move them independently of the home value.
