Property tax rate | 1.25% |
These numbers determine taxable value and annual liability.
A county property tax calculator usa may combine:

Some counties use mill rates:
Property Tax=Assessed Value×Mill Rate1000\text{Property Tax} = \frac{\text{Assessed Value} \times \text{Mill Rate}}{1000}Property Tax=1000Assessed Value×Mill Rate
A mill represents $1 of tax for every $1,000 of assessed value.
Suppose:
Item | Amount |
Home value | $500,000 |
Assessment ratio | 80% |
Assessed value | $400,000 |
Tax rate | 1.2% |
Annual property tax:
400000×0.012=4800400000 \times 0.012 = 4800400000×0.012=4800
Estimated annual property tax = $4,800
Annual Tax | Monthly Escrow |
$4,800 | $400 |
$6,000 | $500 |
$9,600 | $800 |
Mortgage lenders often collect these taxes monthly through escrow accounts.
Some states assess only a portion of market value.
Example:
Item | Value |
Market value | $350,000 |
Assessment ratio | 70% |

Item | Amount |
Assessed value | $300,000 |
Homestead exemption | $50,000 |
Taxable value | $250,000 |
This lowers the final property tax bill.
The taxable value formula is:
Taxable Value=Assessed Value−Exemptions\text{Taxable Value} = \text{Assessed Value} – \text{Exemptions}Taxable Value=Assessed Value−Exemptions
