Question 1

How are property taxes calculated?

Accepted Answer

Three steps: (1) the assessor sets an assessed value (often a percentage of market value), (2) any homestead or senior exemption is subtracted, (3) the local mill rate is applied. Formula: tax = max(0, market × assess_ratio − exemption) × rate. National median is ~1.10% of market value per year.

Question 2

How is 'assessed value' different from market value?

Accepted Answer

Assessed value is what the local government uses to tax your home — it's set by the county assessor, often less frequently than market prices change. In states like California (Prop 13), it can be capped at the original purchase price plus 2% per year, even if the market doubles. In Texas, it's typically reset to market value annually.

Question 3

How are property taxes calculated on new construction?

Accepted Answer

When new construction is completed, the assessor visits and sets the value as of the certificate of occupancy date. Until then, you're typically taxed on the bare land only. Many builders include the property tax delta in the closing costs, but the first full bill arrives the next assessment cycle (often the year after move-in). Plan for a step-up in your escrow.

Question 4

What's a 'mill rate' and how does it relate to a percentage?

Accepted Answer

A mill is one dollar of tax per $1,000 of assessed value, or 0.1% expressed differently. A 11-mill rate equals 1.10%. Local governments often quote the rate in mills because the budget math comes out cleaner; this calculator converts directly to percentage. Most U.S. counties have rates between 0.5% and 2.5%.

Question 5

Is property tax the same on a rental property?

Accepted Answer

Same calculation, but most homestead exemptions don't apply to rentals — the exemption is reserved for primary residences. So a rental with the same market value usually pays more in property tax than an owner-occupied home in the same county. Property tax on rentals is, however, fully deductible as a rental expense on Schedule E.

Question 6

Can I appeal my property tax bill?

Accepted Answer

Yes — virtually every county has an appeal process. The most common winning strategy is showing recent comparable sales (comps) at lower prices, or pointing out errors in the assessor's record (wrong square footage, wrong number of bathrooms). Filing windows are short (often 30–60 days from the assessment notice). Roughly 20–40% of appeals succeed in reducing the bill.

Question 7

Are property taxes deductible on federal taxes?

Accepted Answer

Yes, but capped. The 2017 Tax Cuts and Jobs Act limited the SALT (State and Local Tax) deduction to $10,000 per year through 2025, which includes state income tax + property tax combined. If you itemize and your state has high income tax, you may already be at the cap from income tax alone, making property tax effectively non-deductible. Check IRS Publication 530.
