Property Tax Calculator

What is property tax?

Property tax is a recurring charge on real estate, usually collected by local governments. The bill helps fund public services. The amount depends on the value subject to tax, any exemptions and the applicable tax rate.

This property tax calculator estimates a yearly bill and a monthly equivalent. It uses your home value as the starting point, subtracts the exemptions you enter, then multiplies the taxable value by the rate. If you leave the exact rate at 0, it uses the state effective rate in the calculator. That rate is based on owner-occupied homes and 2024 Census data.

Why property tax matters

Property tax adds to the cost of owning a home, alongside mortgage payments, insurance and upkeep. If you are comparing homes, estimating the tax bill can help you compare the full monthly cost rather than focusing only on the purchase price.

Your actual bill may differ from this estimate. Local rates and property assessments can vary within a state, and an exemption may depend on your circumstances. If you pay property tax through an escrow account, a change in the bill can also affect the amount collected with your mortgage payment.

Use the estimate when you are planning a housing budget, considering a move or checking whether a proposed home fits your finances. For a tax exemption, assessment appeal or other tax decision, confirm the details with your local assessor and a qualified tax professional.

How to use this property tax calculator

1. Enter the home value you want to use. For a home you already own, you can start with the value used in your local assessment or enter another value to test a scenario.
2. Choose the state where the property is located. The calculator uses that state's effective rate when you leave the exact tax rate at 0.
3. Enter the dollar value of exemptions you expect to apply. If you are unsure whether you qualify or what amount applies, check with your local assessor before relying on the estimate.
4. Enter your exact tax rate if you know it and want to override the state estimate. Your property tax bill or local assessor may provide the rate. Otherwise, leave this field at 0.
5. Review the yearly estimate, monthly equivalent, taxable value and rate. Treat the monthly amount as a budgeting aid, not necessarily the amount your lender will collect.

How to read your property tax estimate

The taxable value is the home value after subtracting the exemptions you entered. The yearly tax is that taxable value multiplied by the displayed rate. The monthly figure divides the yearly estimate into monthly amounts for easier budgeting.

The state effective rate is a broad estimate, not a promise of your bill. It may not reflect your local rate, assessment, exemptions or any changes that apply to your property. An exact rate can make the estimate more useful, but your official bill is the figure to use when planning a payment.

How to manage your property tax cost

1. 01

   Check exemptions

   Review your local assessor's requirements for homestead or other exemptions, and submit any required application. The calculator only subtracts the exemption amount you enter. For context, the supplied 2026 figure for the Texas school homestead exemption is $140,000, with an additional $60,000 for someone who is 65 or older or disabled. Confirm which rules apply to your property and situation.

2. 02

   Review the assessment

   Compare the property details on your assessment with the home itself. Check for errors in the recorded size, features or ownership information. If the assessed value seems wrong, ask the local assessor how to request a review and what evidence to provide.

3. 03

   Plan around the bill

   Set aside money using the yearly estimate, then update your budget when you receive the official bill. If you have a mortgage escrow account, check whether a tax change will affect your monthly mortgage payment.

4. 04

   Compare homes using total cost

   When deciding what to buy, compare estimated property tax alongside the mortgage payment and insurance. A lower-priced home may not have a lower overall monthly cost if its tax estimate is higher.

Common property tax calculator mistakes

• Treating the state rate as your local rate

  The default is a state effective rate, so it may not match the rate for your address. Enter your exact rate when you have it, and check the official bill for the amount owed.

• Entering an exemption you may not receive

  An exemption can depend on eligibility and local requirements. Do not subtract a possible exemption from your budget until you have confirmed that it applies.

• Assuming the monthly estimate is your payment

  The monthly result is the yearly estimate divided into monthly amounts. Your lender's escrow collection or local billing schedule may differ.
