Here's how to lower your property taxes in Mercer county

Contact the county assessor

Contact the Mercer county tax assessor's office and ask for a review of the property's value. Visit the Mercer county assessor's website to find the phone number to call. If the assessor determines that your property is worth less than the value on which your taxes are based, your property taxes may be lowered.

Tax exemptions

Start by finding what your tax bill is. Typically you will find your tax bill information on your mortgage statement. Look for tax exemptions or credits that you may be eligible for. Many states and localities offer exemptions or credits for homeowners who meet certain criteria, information such as being over a certain age or having a low income. Mercer county may have these types of exemptions available for homeowners. These exemptions and credits can lower the property tax you owe.

Appeal tax assessment

Appeal the property tax assessment. If you believe that your property's value has been overestimated, you can typically appeal the assessment to your Mercer county tax assessor's office. This is part of the services that your assessor's office provides. You will need to provide evidence to support your claim, such as a recent appraisal or sales data for comparable properties and homes in your area. Usually, you will meet with the Board of Equalization. If your appeal is successful, your property taxes may be lowered.

Challenge the tax rate

Consider challenging the tax rate. In some cases, the amount of property taxes you owe is not based on the value of your property, but on the tax rate set by your local government. If you believe that the tax rate is too high, you can contact your Mercer county government and ask them to consider reducing it.

Property Tax Rules

Stay up-to-date on your property's value and property tax rules. For the purpose of lowering your Mercer county property tax, property value is the assessed property value and not the market property value. Assessed property value is used for taxation purposes while market property value is what a buyer and seller would likely agree on. Typically the assessed value is lower than the market value. Your property's value can change over time due to a variety of factors, such as changes in the local real estate market or improvements you make to your property. To ensure that your property taxes are accurate and fair, it is important to stay informed about your property's value and contact Mercer county local tax assessor's office if you believe there has been a significant change.

Keep in mind that property tax laws and regulations can vary, so it is important to consult with your Mercer county New Jersey tax assessor's office for specific information about how to reduce your property taxes.
