Property Tax on a $400K Home by State
Property tax rates vary dramatically across the United States, from 0.28% in Hawaii to 2.49% in New Jersey. On a $400,000 home, this means annual property taxes ranging from $1,120 (Hawaii) to $9,960 (New Jersey) — a difference of $8,840 per year, or $737 per month added to your mortgage payment.
The national average effective property tax rate is about 1.1%, which translates to $4,400/year on a $400,000 home. States in the Northeast (NJ, IL, CT, NH) and parts of the Midwest tend to have the highest rates, while Southern states (AL, LA, MS, SC) and Hawaii have the lowest.

Frequently Asked Questions
Which states have the highest property tax on a $400K home?
The five highest property tax states (effective rates): New Jersey (2.49% = $9,960/year), Illinois (2.27% = $9,080/year), New Hampshire (2.18% = $8,720/year), Connecticut (2.15% = $8,600/year), and Vermont (1.90% = $7,600/year). These states typically have higher local government spending on schools and services. On a 30-year mortgage, high property taxes add $700-$830/month to PITI compared to the national average.
Which states have the lowest property tax on a $400K home?
The five lowest property tax states: Hawaii (0.28% = $1,120/year), Alabama (0.41% = $1,640/year), Colorado (0.51% = $2,040/year), Louisiana (0.55% = $2,200/year), and Wyoming (0.57% = $2,280/year). However, low-property-tax states often compensate with higher sales tax or state income tax. Hawaii's low rate is offset by high home prices and a higher cost of living overall.
How does property tax affect my monthly mortgage payment?
Property tax is collected monthly as part of your mortgage payment (via escrow) and is a key component of PITI. On a $400K home: at 1.1% (national average), tax is $4,400/year = $367/month; at 2.49% (NJ), it's $830/month; at 0.41% (AL), it's $137/month. This $693/month difference between high and low states can significantly affect affordability. Always check the local property tax rate before buying.
Are property taxes deductible on federal taxes?
Yes, but with limitations. The SALT (State and Local Tax) deduction caps total state and local taxes (property + income OR sales tax) at $10,000 per return ($5,000 married filing separately) through 2025 under the TCJA. On a $400K home in NJ with $9,960 property tax, you'd likely hit the $10K SALT cap. In low-tax states, you may not exceed the standard deduction ($13,000 single / $26,000 married), making itemizing less beneficial. High-income earners in high-tax states bear the highest effective cost.
