How this Property Tax Proration Calculator works
The selected tax year is divided at the closing date using the chosen ownership convention. Each party’s share equals annual tax multiplied by its days of ownership divided by the selected year basis.
Important: Closing customs, inclusive-day rules, tax periods and paid-in-advance versus arrears treatment vary by state, county and contract. Use the settlement agent’s calculation for closing.
What assumptions should I verify?
Verify every entered quantity, rate, unit, product specification and local requirement before relying on the estimate. U.S. conventions are primary where location matters.
Is information sent anywhere?
No. Calculations run locally in the browser and this calculator sends no entered information to a remote service.
