Real estate tax is a yearly bill you pay to your local government based on what your property is worth

Real estate tax — also called property tax — is an annual payment to your city, county, or school district. The amount depends on your property's assessed value, which is set by a local assessor's office, not by what you paid for the house or what it could sell for today. You receive a bill once or twice a year, and the money funds local services: schools, fire departments, roads, libraries, and county administration.

The tax is calculated by multiplying your property's assessed value by the local tax rate, which varies widely by location. A house worth $300,000 in one county might owe $3,000 per year, while the same house in another county might owe $6,000 or $1,500. The rate depends entirely on where you live and what your local government needs to fund.

If you have a mortgage, your lender usually requires you to pay real estate tax through an escrow account — money you add to your monthly payment that the lender holds and pays to the tax collector on your behalf. If you own the property outright, you pay the tax bill directly to your assessor's office or county treasurer.

Key Takeaways

  • Real estate tax is based on your property's assessed value, not its market value or purchase price, and is set by your local assessor's office.
  • Tax rates vary by location and can range from less than 0.5% to over 2% of assessed value, depending on your county or municipality.
  • If you have a mortgage, your lender typically collects real estate tax through an escrow account added to your monthly payment.
  • You can usually find your assessed value and tax rate on your county assessor's website or by calling the assessor's office directly.

How assessed value is determined

Your property's assessed value is not the same as its market value. The assessor's office estimates what your property would sell for on the open market, then applies a local assessment ratio — often 50% or 100% of that estimate — to arrive at the assessed value used for tax purposes. In some states, the assessed value is the full market estimate; in others, it is a fraction of it.

Assessors use several methods to estimate value: comparing your property to similar homes that recently sold nearby, calculating the cost to rebuild your house from scratch, or analyzing the income your property could generate if rented. Most use a combination. The assessor visits your property periodically — sometimes every year, sometimes every three to five years — to note changes like additions, renovations, or deterioration that affect value.

You can usually find your assessed value on your tax bill or on your county assessor's website. If you believe the assessment is wrong — because your house was overvalued, or because a recent sale of an identical nearby home shows yours is worth less — you can file a formal challenge called an assessment appeal or tax assessment protest. The process and deadline vary by state; most require you to file within 30 to 60 days of receiving your tax bill.

Tax rates and how they vary by location

Real estate tax rates are set by local governments and vary dramatically. New Jersey, Illinois, and Connecticut have average rates above 1.5% of assessed value. Hawaii, Alabama, and Louisiana have average rates below 0.5%. Within a single state, rates can differ between counties and between municipalities within the same county.

The rate is usually expressed as a percentage or as a dollar amount per $1,000 of assessed value. A rate of 1.2% means you owe $1,200 per year on a property assessed at $100,000. A rate expressed as "$12 per $1,000" means the same thing. Your tax bill should show both the assessed value and the rate applied, so you can verify the math yourself.

Rates change when local governments adjust their budgets. If a school district needs more funding, the rate may increase. If a municipality receives grant money or cuts spending, the rate may decrease. You can find your local rate on your tax bill, on your county assessor's website, or by calling the assessor's office. Comparing rates between nearby towns can help you understand why your bill is higher or lower than a neighbor's in a different municipality.

Who pays real estate tax and when

Anyone who owns real property — a house, condo, apartment building, or land — owes real estate tax to the jurisdiction where the property sits. If you own the property outright, you pay directly. If you have a mortgage, your lender typically requires you to pay through escrow, meaning you add the estimated annual tax to your monthly payment in twelve equal installments, and the lender pays the bill when it comes due.

Tax bills are usually issued once or twice per year, depending on your location. Some counties bill in spring and fall; others bill once annually. The due date varies by state and county — some are due in December, others in April or June. If you miss a payment, you owe a penalty and interest, which accumulate quickly. After a set period — usually two to three years of non-payment — the county can place a lien on your property or sell it at a tax sale to recover the debt.

If you rent rather than own, you do not pay real estate tax directly. Your landlord pays it, and the cost is typically factored into your rent. If you own a condo, you may pay real estate tax on your unit separately, or your condo association may pay a single tax bill for the entire building and pass the cost to owners through association fees.

Exemptions and reductions you may may have access to for

Many states and localities offer real estate tax exemptions or reductions for specific groups: seniors, veterans, people with disabilities, agricultural properties, and nonprofits. An exemption removes a portion of your assessed value from taxation; a reduction lowers your tax rate. The programs vary widely by location.

Common exemptions include homestead exemptions (available in many states to primary residents), senior exemptions (often for people over 65 with income below a threshold), and veteran exemptions (for military service members or their surviving spouses). Some states offer exemptions for properties used for religious, educational, or charitable purposes. Agricultural land in developing areas often receives special assessment to keep the tax low and preserve farming.

To learn whether you may may have access to, contact your county assessor's office or visit their website. Most exemptions require you to file a form and provide proof — a birth certificate for age, discharge papers for military service, or a deed showing you are the primary resident. Deadlines vary; some are year-round, others have a specific filing window. Missing the deadline usually means waiting until the next year to apply.

How to read your tax bill and find your rate

Your real estate tax bill shows your property's assessed value, the tax rate applied, and the amount you owe. It also lists the due date and where to send payment. Some bills break down how much of your payment goes to schools, county services, and other funds — useful information if you want to understand where your money goes.

To find your tax rate, divide the total tax owed by the assessed value. If your bill shows $2,400 owed on a property assessed at $200,000, your rate is 1.2%. You can compare this to your county's average rate to see whether your property is taxed higher or lower than typical. If the rate seems wrong, check that the assessed value matches what you expect; an error there is the most common source of an unexpectedly high bill.

Your county assessor's office website usually displays assessed values and tax rates for all properties in the county. You can search by address to see your own information and to compare your assessment to similar nearby properties. If you see a discrepancy — your house assessed at $350,000 while an identical one down the street is assessed at $300,000 — that is grounds for an appeal.

What happens if you do not pay real estate tax

If you miss a real estate tax payment, penalties and interest begin accumulating immediately. Penalty rates vary by state but typically range from 5% to 10% of the unpaid amount, plus interest of 6% to 12% per year. After 30 to 90 days, the county may send a notice; after six months to a year, a lien is placed on your property, which shows up on your credit report and makes it difficult to sell or refinance.

If taxes remain unpaid for two to three years, the county can hold a tax sale, where your property is sold to recover the debt. The buyer receives a deed and can eventually take ownership. Some states allow you a redemption period — usually one to three years after the sale — during which you can reclaim the property by paying the buyer the sale price plus interest and costs. If you do not redeem, you lose the property.

If you are struggling to pay, contact your county treasurer or assessor's office immediately. Many jurisdictions offer payment plans, tax deferrals for seniors or disabled owners, or hardship waivers. Acting early prevents a lien and gives you options; waiting until a tax sale is imminent leaves you very few.

Frequently Asked Questions

Is real estate tax the same as property tax?

Yes, the terms are used interchangeably. Real estate tax, property tax, and ad valorem tax all refer to the same annual payment based on your property's assessed value. Some people use "property tax" more broadly to include personal property taxes (on vehicles or business equipment), but in the context of housing, they mean the same thing.

Can I deduct real estate tax from my federal income taxes?

Yes, if you itemize deductions on your federal tax return. The deduction is capped at $10,000 per year (including state and local income taxes combined) under current federal law. You will need to report the amount on Schedule A. Consult a tax professional to determine whether itemizing benefits you more than taking the standard deduction.

Why is my assessed value so much higher than what I paid for the house?

Assessed value is based on current market value, not your purchase price. If you bought years ago, the market may have risen significantly. If you bought recently at a high price, the assessor may not have updated the assessment yet — assessments lag behind sales by a year or more in many places. You can file an appeal if you believe the assessment is too high.

What if I disagree with my assessed value?

File an assessment appeal with your county assessor's office. You will need to submit the form (usually available on the assessor's website) within the deadline — typically 30 to 60 days of receiving your tax bill. Bring evidence: recent sales of comparable homes, a professional appraisal, or photos showing your property is in worse condition than the assessor noted. Many appeals are resolved by mail; others require an in-person hearing.

Do I have to pay real estate tax if I own my home outright?

Yes. Real estate tax is owed by anyone who owns property, whether the property is paid off or financed. If you have a mortgage, your lender collects it through escrow. If you own outright, you pay the bill directly to your county treasurer or assessor's office. Failure to pay results in penalties, liens, and eventually a tax sale.
