Calculation methodology
Property Tax Rates by State (2026 Effective Rates)
Effective property tax rate = taxes actually paid ÷ home market value. This is more useful than the nominal mill rate because it accounts for assessment ratios.
| State | Effective Rate | On $400k Home |
|---|---|---|
| New Jersey | 2.2% | $8,800/yr |
| Illinois | 2.1% | $8,400/yr |
| Texas | 1.7% | $6,800/yr |
| Florida | 0.90% | $3,600/yr |
| California | 0.75% | $3,000/yr |
| Arizona | 0.60% | $2,400/yr |
| Hawaii | 0.30% | $1,200/yr |
Property Taxes and Your Mortgage
Most lenders require property taxes to be paid through an escrow account — meaning your monthly mortgage payment includes 1/12 of your annual tax bill. On a Texas home valued at $420,000 with a 1.7% effective rate, that’s $7,140/year or $595/month added to your mortgage payment. Factor this into affordability before buying.
Homestead Exemptions
Most states offer homestead exemptions that reduce the taxable value of your primary residence. Florida offers up to $50,000. Texas offers $100,000 off the school district portion. California’s Prop 19 offers $7,000 off assessed value. File for every exemption your jurisdiction offers — they’re free money you have to claim proactively.
