See the annual and monthly difference at a glance.
Property tax comparison calculates the annual and monthly tax for the same home value under two different tax rates, then shows you the difference. This is essential when deciding between two locations or evaluating the impact of a rate change.
The formulas:
Annual Tax = Home Value × (Tax Rate / 100)
Monthly Tax = Annual Tax / 12
Annual Difference = |Tax at Rate 1 - Tax at Rate 2|
Monthly Difference = Annual Difference / 12
What the variables mean:
- Home Value — the assessed value of the property (not necessarily the market price; many jurisdictions assess at a fraction of market value)
- Tax Rate 1 and Tax Rate 2 — the two property tax rates you want to compare, expressed as a percentage
Typical US property tax rates by state:
| Rate Range | Example States |
|---|---|
| 0.3-0.6% (low) | Hawaii, Alabama, Colorado |
| 0.9-1.2% (average) | Florida, California, Virginia |
| 1.5-2.0% (high) | Texas, Connecticut, Wisconsin |
| 2.0-2.5% (very high) | New Jersey, Illinois |
The national average is approximately 1.1%.
Practical example: For a $400,000 home, comparing a 1.1% rate vs. a 2.3% rate: Tax at 1.1% = $4,400/year ($367/month). Tax at 2.3% = $9,200/year ($767/month). The difference is $4,800 per year ($400/month). Over a 30-year mortgage, that difference totals $144,000.
Tips: Property tax rates can change annually, so check the recent trend in any area you are considering. Some states offer homestead exemptions that reduce the taxable value for primary residences. When comparing locations, also consider that lower property tax areas sometimes have higher income or sales taxes to compensate. The assessed value may be reassessed periodically, which can increase your tax even if the rate stays the same.
