Real estate tax is an annual property tax your local government charges based on what your home or land is worth

Real estate tax — also called property tax — is money you owe each year to your city, county, or school district. The amount depends on the assessed value of your property, which a local assessor determines. Unlike income tax (which is federal) or sales tax (which varies by purchase), real estate tax is local and goes directly to fund schools, roads, fire departments, and other services in your area.

The tax is usually paid to your county assessor's office or tax collector. If you have a mortgage, your lender often collects the payment as part of your monthly escrow account and pays it on your behalf. If you own the property outright, you pay directly. The bill arrives once or twice a year depending on where you live.

Key Takeaways

  • Real estate tax is calculated by multiplying your property's assessed value by the local tax rate, which varies significantly by county and state.
  • The assessed value is not the same as the market value — assessors use formulas based on recent sales, property condition, and size to set it lower than what you paid.
  • If you have a mortgage, your lender collects real estate tax through escrow and pays it automatically; if you own outright, you receive a bill directly from your county.
  • Most states and counties offer exemptions or reductions for seniors, veterans, people with disabilities, and owner-occupied homes, which can lower your annual bill significantly.
  • You can challenge your assessed value through a formal appeal process if you believe it is too high, though deadlines and procedures vary by location.

How the assessed value is determined

Your county assessor's office assigns an assessed value to your property, which is the starting point for calculating your tax bill. Assessors typically use one of three methods: the sales comparison approach (looking at recent sales of similar homes), the cost approach (estimating what it would cost to rebuild your home), or the income approach (used mainly for rental properties). The assessed value is usually lower than the actual market price you paid or could sell for.

Assessors visit properties periodically — sometimes every year, sometimes every three to five years — to note changes like additions, renovations, or deterioration. They also review public records of recent sales in your area. If you recently bought your home, the assessor may use your purchase price as a starting point, though they often adjust it based on condition and comparable sales. The frequency of reassessment and the methods used vary by state and county.

The tax rate and how your bill is calculated

Once your property has an assessed value, your local government applies a tax rate to calculate what you owe. The rate is set by your county, city, school district, and sometimes special districts (like water or fire protection). Each of these entities sets its own rate, and they add together. For example, your county might charge 0.8%, your city 0.3%, and your school district 1.2%, for a combined rate of 2.3%.

The calculation is straightforward: assessed value multiplied by the combined tax rate equals your annual bill. If your home is assessed at $200,000 and your combined rate is 2.3%, you owe $4,600 per year. Tax rates vary dramatically by location — some areas charge less than 0.5%, while others exceed 2.5%. Your county assessor's office or tax collector can tell you the exact rate for your property and break down which entities are charging what portion.

Exemptions and reductions that lower your bill

Most states and counties offer exemptions or assessment reductions that can lower your real estate tax bill. Homestead exemptions — available in many states — reduce the assessed value for owner-occupied homes. Senior exemptions typically apply at age 65 or older and may reduce your bill by 10% to 50% depending on your state and income. Veteran exemptions are common in states with large military populations and can be substantial.

People with disabilities may receive exemptions or deferrals in some states. Agricultural land, forest land, and other special-use properties often receive lower assessments than residential or commercial land. To claim an exemption, you usually file a form with your assessor's office by a specific deadline — often in spring. Missing the deadline typically means waiting until the next year to claim it. Contact your county assessor to learn which exemptions you might be may have access to to and what documentation you need to provide.

What happens if you disagree with your assessed value

If you believe your assessed value is too high, you can file a formal appeal. The process and timeline vary by state and county, but the basic steps are similar: you file a written objection with your assessor or a board of appeals, usually within 30 to 60 days of receiving your tax bill. You will need to provide evidence — comparable sales of similar homes, a recent appraisal, photos of property damage, or documentation of needed repairs.

Some counties hold informal hearings where you can present your case in person; others require written submissions only. If the assessor's office denies your appeal, you may be able to appeal to a county board of review or equalization board. A few states allow further appeal to tax court, though this usually requires hiring an attorney. The entire process can take several months to over a year. Even if you win, the reduction typically applies only to the current year, and you may need to appeal again the following year if the assessed value is raised.

Real estate tax versus other property-related costs

Real estate tax is separate from other costs of homeownership. Mortgage interest and property insurance are not the same as real estate tax, though all three are often bundled into your monthly escrow payment if you have a loan. Homeowners association (HOA) fees, if you live in a community with one, are also separate and go to the HOA, not the government. Special assessments — one-time charges for major infrastructure projects like sewer repairs — are different from annual real estate tax but may appear on your tax bill.

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. Understanding the difference between these costs matters when budgeting and when comparing the true cost of homeownership in different areas.

How real estate tax revenue is used

Real estate tax funds local services that benefit your community. The largest portion typically goes to public schools — often 40% to 60% of the total bill depending on your location. The remainder funds county operations (courts, sheriff, assessor's office), city services (police, fire, public works, parks), and special districts (water, sewer, library, fire protection). Because schools receive the largest share, areas with higher property values and higher tax rates often have better-funded school systems.

This is why real estate tax rates can vary so dramatically between neighboring counties or even between school districts within the same county. A wealthy suburban area may have a lower tax rate because property values are high, while a rural area with lower property values may have a higher rate to generate the same revenue. Understanding where your tax dollars go can help you see the connection between your bill and the services you use.

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 deduction is capped at $10,000 per year (combined with state and local income taxes and sales taxes) under current federal law. Most homeowners with mortgages can deduct real estate tax, but you must file Schedule A instead of taking the standard deduction. Consult a tax professional to determine whether itemizing saves you money.

What happens if I don't pay my real estate tax bill?

Your county can place a lien on your property, meaning they have a legal claim against it. If you continue not to pay, the county may eventually foreclose and sell your home to recover the unpaid taxes and penalties. Most counties offer payment plans or deferrals for people facing hardship. Contact your tax collector immediately if you cannot pay — waiting makes the problem worse.

Does my real estate tax bill change every year?

Usually, yes, but the amount and reason vary. Your assessed value may increase if you made improvements, or it may be reassessed based on market changes. Tax rates set by your county, city, and school district also change year to year. Some states cap how much the assessed value can increase annually (often 2% to 3%), which slows the growth of your bill. Check your bill each year to see what changed.

How do I find out my property's assessed value?

Your county assessor's office maintains public records of all assessed values. You can usually search online by address on the assessor's website, or call the office directly. Your tax bill also lists the assessed value. If you want a formal appraisal for your own records or to support an appeal, you can hire a licensed appraiser, though this costs money.

Is real estate tax the same in every state?

No. Tax rates, assessment methods, exemptions, and appeal processes all vary significantly by state and county. Some states tax property heavily and fund schools primarily through property tax; others rely more on income tax. Before buying a home in a new area, research the local real estate tax rate and any exemptions you might receive — the difference can be thousands of dollars per year.
