Your property tax bill comes from your local assessor and tax collector, not from a state or federal office

The amount you owe depends on three things: the assessed value of your property (set by your county or municipality), the tax rate in your area (set by local government), and any exemptions you may may have access to for. Because all three vary by location, two identical houses in different counties can have very different tax bills. Your property tax bill is mailed to you once or twice a year, depending on where you live — usually in spring and fall, or as a single annual bill.

If you have not received a bill, or if you want to know what you will owe before the bill arrives, you can look it up yourself through your local assessor's office. Most counties now post property records online, searchable by address or parcel number. The assessor's office also has the assessed value and the current tax rate for your area.

Key Takeaways

  • Your local assessor's office sets the assessed value of your property, and your local tax collector's office sends you the bill based on that value and your area's tax rate.
  • Most counties post searchable property records online where you can find your assessed value, tax rate, and estimated annual bill without calling anyone.
  • The assessed value is usually lower than the market value of your home, and it is reassessed every few years or when you sell the property.
  • If you disagree with the assessed value, you can file a formal challenge called an assessment appeal or tax assessment protest, which has a important date that varies by state.
  • Homeowners may reduce their bill through exemptions such as homestead exemptions, senior exemptions, or disability exemptions — each state and county sets its own rules.

How to find your assessed value and tax rate online

Start by visiting your county assessor's website. Search for "[your county name] assessor" or "[your county name] property records." Most counties have a searchable database where you enter your address or parcel number and see the assessed value, recent sales data, and the property description on file.

Once you have the assessed value, find your local tax rate. This is usually posted on your county tax collector's website or your assessor's website. The tax rate is expressed as a percentage or as a dollar amount per $1,000 of assessed value — for example, 1.2% or $12 per $1,000. Multiply your assessed value by the tax rate to get your estimated annual bill. If your county sends two bills per year, divide that number by two.

If the online database is down or you cannot find your parcel number, call your county assessor's office directly. They can tell you the assessed value over the phone and direct you to the tax collector's office for the current rate and bill status.

Why your assessed value is different from what you think your home is worth

The assessed value is not the same as the market value — the price your home would sell for today. Assessors use the assessed value to calculate taxes, and they typically set it lower than market value. Some states cap how much the assessed value can increase each year, even if the market value rises sharply. Other states reassess the value only when the property changes hands.

Assessors use several methods to set value: they may compare your home to recent sales of similar homes in your area, estimate the cost to rebuild it, or use income data if the property is a rental. The method varies by county. Your assessment notice should explain which method was used and what information was considered.

You can usually find the assessed value on your property tax bill, your assessment notice (mailed separately from the bill), or the county assessor's online database. If you have owned the home for several years and have not received an assessment notice recently, the assessed value may not have changed since your last purchase.

How exemptions lower your tax bill

Many states and counties offer exemptions that reduce the assessed value or the tax rate for certain homeowners. The most common is the homestead exemption, which lowers the assessed value for owner-occupied primary residences. Some states exempt a flat dollar amount — for example, $50,000 off the assessed value — while others exempt a percentage.

Other exemptions include senior exemptions (for homeowners over a certain age, usually 65), disability exemptions, veteran exemptions, and agricultural exemptions (for land used for farming). 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.

Check your assessment notice or call your assessor's office to ask which exemptions you may be may have access to to. If you may have access to but have not claimed one, you can usually file a claim form. The important date to claim an exemption varies by state — some allow claims year-round, while others have a specific filing window in spring or fall.

What to do if you think your assessed value is too high

If you believe your assessed value does not reflect the true value of your property, you can file a formal challenge. This process is called an assessment appeal, a tax assessment protest, or a value appeal, depending on your state. The first step is to file a written notice with your county assessor or a local board of assessment appeals, stating why you think the value is wrong.

You will need to support your claim with evidence. Common evidence includes a recent professional appraisal, recent sales prices of similar homes in your neighborhood, or photographs showing damage or needed repairs. The assessor's office will review your claim and may adjust the value. If you disagree with their decision, you can appeal to a higher board or, in some states, to tax court.

The important date to file an appeal is strict and varies by state — it may be 30 days after you receive your assessment notice, or it may be in a specific month like March or April. Missing the important date usually means you cannot challenge that year's assessment. Check your assessment notice for the important date, or call your assessor's office to confirm.

Understanding your property tax bill when it arrives

Your property tax bill will show the assessed value, the tax rate, and the amount due. It will also show the due date and where to send payment. Some bills include a breakdown of how the tax money is split among different services — schools, roads, fire department, and so on — though this varies by county.

If you pay your mortgage through an escrow account, your lender may pay the property tax bill directly from that account. If you pay the bill yourself, you can usually pay online, by mail, or in person at the tax collector's office. Late payments typically result in a penalty and interest, so mark the due date on your calendar.

If your bill seems unusually high compared to previous years, it may be because the assessed value was increased, the tax rate went up, or an exemption expired. Call your tax collector's office to ask what changed. If you think there is an error — for example, if the bill lists the wrong property or the wrong owner — report it when ready so it can be corrected.

Frequently Asked Questions

How often is my property reassessed?

This varies by state and county. Some counties reassess every year, while others reassess every three to five years. A few states reassess only when the property is sold. Check your county assessor's website or call their office to find out the reassessment schedule for your area.

Can I get my property tax bill lowered if I made improvements to my home?

Improvements like a new roof or kitchen usually increase the assessed value, not lower it, because they add to the property's worth. However, if you made repairs to fix damage — for example, replacing a roof that was leaking — you may be able to argue that the assessed value should not have increased. Document the work and contact your assessor's office.

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

If you miss the payment important date, you will owe a penalty and interest on top of the original bill. If you do not pay for an extended period, your county may place a lien on the property or, in some cases, foreclose and sell it to recover the unpaid taxes. Contact your tax collector's office when ready if you cannot pay by the due date to discuss payment plans or hardship options.

Do I owe property tax if I own the land outright with no mortgage?

Yes. Property tax is owed by the owner of record, regardless of whether there is a mortgage. If you own the property free and clear, you are responsible for paying the tax bill directly to your county tax collector.

Can I deduct property taxes on my federal income tax return?

You may be able to deduct state and local property taxes on your federal return, but there is a limit. The total deduction for state and local taxes (including property tax, income tax, and sales tax combined) is capped at $10,000 per year. Consult a tax professional or the IRS website to determine whether you can deduct your property taxes.
