Property tax is an annual tax on real estate that your local government uses to fund schools, roads, and public services

When you own land or a building, your city or county assesses its value and charges you a percentage of that value each year. This is property tax, and it is separate from federal income tax or estate tax. The amount you pay depends on three things: what your property is worth, the tax rate in your area, and any exemptions you might have.

Property tax bills arrive once or twice a year, depending on where you live. If you have a mortgage, your lender often collects the tax as part of your monthly payment and pays it to the government on your behalf. If you own the property outright, you receive the bill directly and must pay it yourself.

Key Takeaways

  • Property tax is calculated by multiplying your property's assessed value by your local tax rate, which varies widely by county and state.
  • Your local assessor determines the value of your property, usually by comparing it to similar homes that recently sold in your area.
  • Most states offer exemptions that lower your tax bill — homestead exemptions for primary residences are the most common.
  • If you disagree with your property's assessed value, you can file a formal appeal with your assessor's office.
  • Property tax is deductible on your federal income tax return, up to $10,000 per year in most states.

How the assessed value of your property is determined

Your local assessor's office estimates what your property would sell for on the open market. They do this by looking at recent sales of similar homes in your neighborhood, the condition of your building, the size of your lot, and any improvements you have made. This estimate is called the assessed value, and it is usually lower than what you could actually sell the property for.

Assessors typically reassess properties every one to five years, depending on your state. Some states reassess every year; others do it once a decade. When your property is reassessed, the assessed value may go up or down. If you made major improvements — like adding a room or replacing the roof — the value usually increases. If your neighborhood declines or your home needs significant repairs, it may decrease.

You can request a copy of your property's assessment from your assessor's office at no cost. The assessment record shows the assessed value, the calculation method, and sometimes photos of your property. Reviewing this document is the first step if you think your tax bill is too high.

What the tax rate is and how it varies by location

Your property tax rate is set by your local government — usually your county, city, or school district — and it varies dramatically from place to place. A property worth $300,000 might cost $3,000 per year in one county and $6,000 in another. Rates also change year to year as local governments adjust their budgets.

The tax rate is expressed as a percentage of assessed value or as a dollar amount per $1,000 of assessed value. For example, a rate of 1% means you pay $1 for every $100 of assessed value. A rate of $10 per $1,000 means the same thing. Your property tax bill is calculated by multiplying your assessed value by the rate.

You can find your local tax rate by contacting your county assessor's office or checking your property tax bill, which usually shows the rate clearly. If you are considering buying property in a new area, comparing tax rates between counties is important — it can be one of the largest ongoing costs of homeownership.

Common exemptions that reduce your property tax bill

Most states offer exemptions that lower the assessed value or the tax rate for certain property owners. The most common is the homestead exemption, which reduces taxes on your primary residence. Some states exempt a fixed dollar amount from the assessed value — for example, $50,000 — while others reduce the tax rate itself.

Other exemptions exist for seniors, veterans, people with disabilities, agricultural land, and religious organizations. Each state and county sets its own rules about who qualifies and how much the exemption is worth. Some exemptions are automatic; others require you to file a form with your assessor's office.

To find out what exemptions you might have, contact your county assessor or visit your state's revenue department website. If you are may be able to access and have not claimed an exemption, filing the paperwork can lower your bill significantly. Exemptions typically take effect in the year you file, so there is no benefit to waiting.

How to challenge your property tax assessment if you think it is too high

If you believe your property's assessed value is wrong, you can file a formal appeal with your assessor's office. The process and important date vary by state, but most allow you to file between 30 and 90 days after you receive your tax bill. Some states call this a "protest" or "objection" rather than an appeal.

To build your case, gather evidence that your property is worth less than the assessed value. This might include a recent appraisal, a real estate agent's opinion of value, photos showing needed repairs, or sales prices of comparable homes that sold for less. You do not need a lawyer, though some people hire one if the amount at stake is large.

Submit your appeal in writing to your assessor's office by the important date. Include your property address, the assessed value you are challenging, the value you believe is correct, and your supporting evidence. The assessor will review your case and either adjust the value or uphold it. If you disagree with the result, most states allow a second appeal to a county board or court, though this usually costs money and takes longer.

The difference between property tax and estate tax

Property tax and estate tax are two separate taxes that sometimes confuse homeowners. Property tax is paid every year while you own the property, based on its current value. Estate tax is paid once, after you die, on the total value of everything you owned — including the property, investments, bank accounts, and personal items.

Most people never pay estate tax because the federal exemption is very high (over $13 million in 2023, though this changes with new laws). Property tax, by contrast, is paid by nearly every homeowner every year. If you own a home, you will almost certainly pay property tax. You will likely never pay estate tax unless you are very wealthy.

Understanding the difference matters because they affect your finances in different ways. Property tax is a predictable annual cost you can budget for. Estate tax is something your heirs might face after you die, depending on how much you leave them and what state you lived in.

How property tax appears on your mortgage payment and tax return

If you have a mortgage, your lender typically requires you to pay property tax as part of your monthly mortgage payment. The lender collects the tax along with your principal and interest, holds it in an escrow account, and pays the bill to your local government when it is due. This protects the lender's investment in the property.

Your mortgage statement shows how much of your monthly payment goes toward property tax. You can deduct the property tax you paid during the year on your federal income tax return, up to $10,000 per year (this limit applies to all state and local taxes combined, not just property tax). To claim the deduction, you must itemize deductions on Schedule A rather than taking the standard deduction.

Keep your property tax bills and mortgage statements for your tax records. If you pay property tax directly rather than through escrow, you will need to report the amount you paid when you file your taxes. Your county assessor's office can provide a receipt or statement showing what you paid if you need it for tax purposes.

Frequently Asked Questions

What happens if I do not pay my property tax bill?

If you do not pay by the important date, your county will charge you a penalty and interest. After several months of non-payment, the county can place a lien on your property or sell it at a tax sale to recover the money owed. Paying as soon as you receive the bill avoids these consequences.

Can property tax go down if my home loses value?

Yes, if your property is reassessed and found to be worth less, your tax bill will decrease. This sometimes happens after a major recession or if your neighborhood declines. You can also request a reassessment if you believe your property has lost value since the last assessment.

Do I pay property tax on a rental property I own?

Yes, you pay property tax on any real estate you own, whether it is your home, a rental, or vacant land. Rental property owners can deduct property tax as a business expense on their tax return, which is different from the $10,000 limit that applies to owner-occupied homes.

What is the difference between assessed value and market value?

Assessed value is what your local assessor estimates your property is worth for tax purposes. Market value is what it would actually sell for on the open market. Assessed value is usually lower than market value, and it is the number used to calculate your property tax bill.

Can I transfer my homestead exemption if I move to a new state?

No, homestead exemptions are specific to each state and county. If you move, you will need to file for an exemption in your new location if you want one. The rules and amounts vary, so contact your new county assessor to learn what is available.
