Property tax is a yearly bill based on what your home or land is worth, set by your local government

Property tax is not a federal tax. Your city, county, or school district decides how much you owe each year, based on an assessment of your property's value. The tax rate varies dramatically by location — a house worth $300,000 might cost $3,000 a year in one county and $6,000 in another, depending on local tax rates and what services the tax money funds.

You receive a bill, usually once or twice a year, from your county assessor or tax collector. The bill shows the assessed value of your property, the tax rate applied to it, and the total amount due. If you own the home outright, you pay directly. If you have a mortgage, your lender often collects the tax as part of your monthly payment and pays it on your behalf — this amount is called an escrow payment.

Property tax pays for local services: schools, roads, fire departments, libraries, and county administration. Because these services differ by location, tax rates differ too. A rural county with fewer services may have a lower rate than a suburban county with extensive school systems.

Key Takeaways

  • Property tax is set by your local government and based on your property's assessed value, not its market value.
  • Tax rates vary by county and city, so two identical homes in different locations will have different tax bills.
  • You receive a bill from your county assessor or tax collector, usually once or twice yearly.
  • If you have a mortgage, your lender typically collects property tax through escrow and pays it for you.
  • Property tax funds local schools, roads, emergency services, and other county or city services.

How your property's assessed value is determined

The assessed value is not the price you paid for your home or what it would sell for today. Instead, your county assessor estimates the value using formulas that may include recent sales of similar homes, the property's size and condition, and local market trends. Some states use a percentage of market value — for example, assessing property at 80 percent of what it would sell for. Other states use different methods.

Assessors typically reassess property every one to five years, depending on your state. When they reassess, your tax bill may go up or down. In some states, like California, property is reassessed only when it changes hands, which can keep long-term homeowners' taxes lower than newer residents in the same neighborhood.

You can usually see your property's assessed value on your tax bill or on your county assessor's website. If you believe the assessment is wrong — for example, if the assessor recorded your home as having four bedrooms when it has three — you can file a challenge called an appeal or protest, depending on your state's terminology. The process and important date vary by location.

Understanding the tax rate and how it's calculated

Your property tax bill is calculated by multiplying your assessed value by the tax rate. The tax rate is 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 $15 per $1,000 of value, your tax is $4,500 per year.

Tax rates are set by local governments — usually a county board, city council, or school board — based on the budget they need to fund. If a school district needs $50 million and the total assessed value of all property in the district is $5 billion, the rate is set at 1 percent. Rates can change year to year as budgets change.

Some states cap how much the tax rate can increase in a single year, even if property values rise sharply. Others allow rates to rise without limit. A few states, like Florida and Texas, have no state income tax and rely heavily on property tax instead, so rates tend to be higher.

When and how you pay property tax

Most counties bill property tax once or twice per year. Some send one bill in spring and another in fall. Others send a single annual bill. The due date varies by county — it might be in April, June, September, or December. Your tax bill will show the due date and where to send payment.

You can usually pay by mail, online through your county's website, or in person at the tax collector's office. Some counties allow automatic bank transfers or credit card payments, though credit card payments often include a processing fee. Late payments typically trigger penalties and interest charges that accumulate quickly.

If you have a mortgage, your lender handles this for you. Your monthly mortgage payment includes an escrow amount — a portion set aside for property tax, homeowners insurance, and sometimes mortgage insurance. Your lender collects these amounts and pays the bills when they're due. If your tax bill increases, your lender may adjust your escrow payment upward.

Deductions and exemptions that may lower your bill

Many states and counties offer exemptions that reduce your assessed value or tax bill. Common exemptions include homestead exemptions (for primary residences), senior exemptions (for people over a certain age), disability exemptions, and veteran exemptions. Some states exempt agricultural land or forest land from full taxation.

To claim an exemption, you typically file a form with your county assessor before a specific important date — often early in the year. The form asks you to prove you meet the requirements, such as providing proof of age, disability status, or military service. If you may have access to, the exemption reduces your assessed value, which lowers your tax bill.

At tax time, you cannot deduct property tax on your federal income tax return unless you itemize deductions on Schedule A of Form 1040. If you do itemize, you can deduct up to $10,000 in state and local taxes combined — this includes property tax, state income tax, and sales tax. Most homeowners claim the standard deduction instead, which means they receive no tax benefit from property tax payments.

What happens if you don't pay property tax

If your property tax bill goes unpaid, penalties and interest begin to accumulate. The exact penalties vary by state and county, but they typically range from 5 to 10 percent of the unpaid amount, plus interest that compounds monthly. After a set period — usually one to three years, depending on your location — the county may place a lien on your property, meaning it has a legal claim against it.

If the tax remains unpaid long enough, the county can foreclose on the property and sell it at a tax sale to recover the unpaid taxes. This process takes time, but it is a real consequence. Before foreclosure happens, the county will send notices and may offer a payment plan or other options to resolve the debt.

If you cannot pay your full bill, contact your county tax collector when ready. Many counties offer payment plans, deferral programs for seniors or disabled homeowners, or hardship waivers. The sooner you reach out, the more options you may have.

How property tax differs from income tax and sales tax

Property tax, income tax, and sales tax are three separate taxes that fund different levels of government. Income tax goes to the federal government and some states. Sales tax goes to the state and sometimes the county. Property tax goes to your local county, city, or school district.

Property tax is the only one of the three that is based on ownership of a specific asset rather than on income or spending. It is also the only one that can result in loss of the asset itself if unpaid long enough. Income tax and sales tax do not carry the same foreclosure risk.

Some states have no income tax or no sales tax, but nearly all states have property tax. States that rely heavily on property tax often have higher rates to fund schools and services. States with income tax may have lower property tax rates because they have another revenue source.

Frequently Asked Questions

Why did my property tax bill go up this year?

Your bill can increase for two reasons: your assessed value went up, or the tax rate went up. If your county reassessed property this year and your home's value increased, your bill will rise. If your county or school district raised the tax rate to fund a larger budget, all bills go up. Check your bill to see which changed.

Can I appeal my property tax assessment?

Yes. If you believe your assessed value is too high, you can file an appeal with your county assessor. The important date to file is usually 30 to 60 days after you receive your bill, though it varies by state. You will need to show evidence — such as a recent appraisal, photos of damage, or sales prices of similar homes — to support your claim.

What is escrow and why is it part of my mortgage payment?

Escrow is money your lender holds in a separate account to pay your property tax and homeowners insurance when they're due. Your lender requires this because it wants to may support these bills are paid — unpaid property tax could result in foreclosure, which hurts the lender. You fund the escrow through your monthly payment.

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

Yes. Property tax is owed by anyone who owns real estate, whether the property is paid off or financed. The only difference is who pays the bill — you pay directly if you own it outright, or your lender pays it from escrow if you have a mortgage.

Can I deduct property tax on my income tax return?

Only if you itemize deductions on your federal tax return, and only up to $10,000 combined with other state and local taxes. Most homeowners use the standard deduction instead, which means they get no tax benefit from property tax. Check your situation with a tax professional to see which approach saves you more.
