The formulas
- Annual tax = assessed value x mills / 1,000
- Earned to date = annual tax x months elapsed / 12
- Recomputed liability = earned to date - amount paid
How it works
Property tax is recognized over the tax year it relates to. The liability at period end is the tax earned to date less the payments made; a negative result means the entity paid ahead and holds a prepaid.
Tax years, lien dates and payment schedules differ by jurisdiction. Use the tax year the bill covers, not the billing date. If the current bill is not yet issued, use the prior bill adjusted for known value or rate changes.

Common questions
What is a mill?
One dollar of tax per $1,000 of assessed value, so 21.4 mills is a 2.14% rate on assessed value.
What if the rate is quoted per $100?
Multiply the per-$100 rate by 10 to get mills.
Should appeals be considered?
Accrue the assessed amount unless an appeal outcome is known. Disclose a significant pending appeal.
