Real estate tax is a yearly bill from your local government based on what your property is worth

Real estate tax — also called property tax — is an annual payment you make to your county or municipality. The amount depends on your property's assessed value, which a local assessor estimates based on comparable sales, condition, and location. You do not pay this tax to the federal government; you pay it to the county or city where the property sits.

The tax funds local services: schools, roads, fire departments, libraries, and police. Every state and county sets its own tax rate, so what you owe in one place may be very different from another. A $300,000 home in one county might generate a $3,000 annual bill, while the same home elsewhere could cost $6,000 or more per year.

If you own a home with a mortgage, your lender usually collects the real estate tax as part of your monthly payment. The lender holds the money in an escrow account and pays the county bill when it comes due. If you own the home outright, you receive the bill directly and must pay it yourself.

Key Takeaways

  • Real estate tax is calculated by multiplying your property's assessed value by the local tax rate, and the bill arrives once or twice per year depending on where you live.
  • The assessed value is not the same as the price you paid or the current market value — it is set by a local assessor and can be challenged if you believe it is wrong.
  • If you have a mortgage, your lender collects the tax through escrow and pays it for you; if you own the home outright, you pay the county directly.
  • Missing a real estate tax payment can result in penalties, interest, and eventually a tax lien or foreclosure, so payment is not optional even if you dispute the amount.

How the assessed value is determined

A county assessor's office estimates the value of your property, usually once every one to five years depending on the state. They look at recent sales of similar homes in your area, the condition and age of your building, lot size, and any improvements you have made. This assessed value is the starting point for your tax bill — it is not necessarily what you paid for the home or what it would sell for today.

Assessors use different methods. Some compare your home to recent sales of comparable properties. Others use a cost approach, estimating what it would cost to rebuild your home from scratch and subtracting for age and wear. A few use an income approach if the property generates rental income. The method varies by county and property type.

You can usually see your assessed value on the county assessor's website or by calling the assessor's office. If you believe the value is too high, most counties allow you to file a formal challenge called an assessment appeal or grievance. The deadline to file is typically 30 to 60 days after you receive the assessment notice, though this varies by location.

How the tax rate is set and what you actually owe

Your real estate tax bill is calculated by multiplying your assessed value by the local tax rate. The tax rate is set by your county or municipality and is usually expressed as a percentage or as a dollar amount per $1,000 of assessed value. For example, if your assessed value is $300,000 and the tax rate is 1.2%, your annual bill would be $3,600.

Tax rates vary widely. Some counties charge less than 0.5% of assessed value per year, while others charge 2% or more. States like New Jersey, Illinois, and Connecticut tend to have higher property tax rates, while states like Hawaii, Alabama, and Louisiana tend to have lower rates. Within a state, rates can also differ between school districts and municipalities.

Your bill may include taxes for multiple entities: the county, the school district, the town or city, and sometimes special districts for fire protection or water. Each entity sets its own rate, and they are added together on your final bill. Some counties bill once per year; others bill twice. Check your county assessor's website or tax bill to understand the payment schedule in your area.

What happens if you do not pay

Real estate tax is not optional, even if you disagree with the amount. If you do not pay by the due date, the county adds penalties and interest to your bill. Penalty rates vary but often start at 5% to 10% of the unpaid amount and increase each month the bill remains unpaid.

After a set period — usually 12 to 24 months, depending on the state — the county can place a tax lien on your property. A lien is a legal claim that gives the county a right to the property if the debt is not paid. The lien appears on your property record and makes it difficult or impossible to sell, refinance, or borrow against the home.

If taxes remain unpaid for several years, the county can foreclose on the property and sell it at a tax sale to recover the debt. In a tax sale, you lose ownership of the home. Some states give you a redemption period — usually one to three years after the sale — during which you can reclaim the property by paying the buyer's costs plus interest, but this is not may provide in all states.

Exemptions and reductions that may lower your bill

Many states and counties offer exemptions or reductions for certain property owners. Homestead exemptions reduce the assessed value for primary residences, which lowers the tax bill. Senior citizen exemptions, disability exemptions, and veteran exemptions are common in many states. Agricultural land often receives a lower tax rate than residential or commercial land.

To claim an exemption, you typically file a form with the assessor's office by a set deadline, usually in spring. You will need to prove your status — for example, a deed showing you own the home as your primary residence, a birth certificate or age verification for a senior exemption, or military discharge papers for a veteran exemption. The exemption is not automatic; you must request it.

Some states also allow tax credits or deferrals for low-income homeowners or seniors. A deferral lets you delay paying part of your tax bill until you sell the home or pass it to an heir. A credit reduces your bill directly. These programs vary significantly by state, so contact your county assessor to learn what is available where you live.

The difference between real estate tax and other property-related costs

Real estate tax is separate from other bills you may owe as a homeowner. Homeowners insurance protects your home against damage and is required by lenders; it is not a tax and does not fund government services. Mortgage interest is what you pay the lender for borrowing money; it is not a tax, though you may be able to deduct it on your federal income tax return.

Homeowners association (HOA) fees are dues you pay to a neighborhood association for maintenance of common areas; they are not taxes and go to a private entity, not the government. Special assessments are one-time charges for major repairs or improvements to local infrastructure; they are sometimes called taxes but are technically separate from the annual real estate tax bill.

If you have a mortgage, your monthly payment may include all of these: principal and interest to the lender, homeowners insurance, real estate tax, and sometimes HOA fees or mortgage insurance. Your lender collects them all and pays the bills on your behalf. Understanding which bill is which helps you know where to call if you have a question or dispute.

How to find and pay your real estate tax bill

Your real estate tax bill is mailed to the address on record with the county assessor, usually to the property owner or to the mortgage lender's address if they hold the escrow account. You can also find your bill online through your county assessor's or tax collector's website. Most counties allow you to search by address or parcel number and view your current bill and payment history.

Payment methods vary by county. Many accept checks mailed to the tax collector's office, online payments through the county website, credit card payments (sometimes with a fee), or automatic bank transfers. Some counties allow payment in installments if you request it before the due date. If you are unsure how to pay, call the county tax collector's office — the number is usually on your bill or on the county website.

If you have a mortgage, your lender handles the payment through escrow, so you do not pay the county directly. However, you should still monitor your escrow account to make sure the lender is collecting enough each month. If property taxes increase significantly, your lender may raise your monthly escrow payment. You can request an escrow analysis from your lender to review the account.

Frequently Asked Questions

Can I deduct real estate tax on my federal income tax return?

Yes, if you itemize deductions on your federal return. The State and Local Tax (SALT) deduction allows you to deduct up to $10,000 per year in combined state, local, and property taxes. You must itemize rather than take the standard deduction for this to benefit you. Consult a tax professional to determine whether itemizing makes sense for your situation.

What is the difference between assessed value and market value?

Assessed value is what the county estimates your home is worth for tax purposes; market value is what your home would actually sell for today. Assessed value is often lower than market value because assessors do not update it every year, and they use formulas rather than actual sales data for your specific home. You can challenge an assessment if you believe it is significantly out of line with recent comparable sales.

If I pay off my mortgage, do I still have to pay real estate tax?

Yes. Real estate tax is owed by the property owner regardless of whether there is a mortgage. Once you pay off the mortgage, you will receive the tax bill directly instead of through your lender's escrow account. You become responsible for paying the county on time.

Can real estate tax rates change year to year?

Yes. Tax rates are set annually by the county, school district, and other local entities. Rates can increase or decrease based on the local government's budget needs. Your bill can also change if your assessed value is updated. Some states limit how much the assessed value can increase in a single year, but others do not.

What should I do if I cannot afford my real estate tax bill?

Contact your county tax collector's office to ask about payment plans or deferrals. Some counties allow you to spread payments over several months. If you are a senior, disabled, or low-income homeowner, your state may offer tax relief programs. You can also consult a housing counselor through HUD to explore options; call 211 or visit HUD.gov to find a counselor near you.
