Steps to Estimate Your Property Taxes

If you’re looking to purchase a new home or have recently bought a new home, it is important to calculate your property taxes. Your property taxes will differ from the previous owner’s property taxes because all caps and exemptions are removed once ownership changes.

The most accurate way to estimate your home’s or potential home’s property taxes is to use the tax estimator available on this website. The online tax estimator utilizes the most recently certified millage rates, typically from the preceding tax roll year, to create an estimate of property taxes. Non-ad valorem assessments are based on those most recently assessed to the parcel being estimated. These assessments are subject to change and may be higher or lower in the next tax year.

Here are the steps to use our online tax estimator. Images of the property search and tax estimator screens are used below for reference.

  • For Just (Market) Value, use the potential purchase price or sale price of the property.

  • For Exemptions, select if you have any of the listed exemptions. If you check Homestead, the list of exemptions will expand to show additional exemptions that are offered to those with homesteaded properties.

  • For SOH Portability Amount, add your Save Our Homes or Portability total that will be transferred from your previously owned homesteaded property. This number can be calculated by subtracting the property’s Assessed Value from the Just (Market) Value. You can also find this number by viewing the TRIM notice of the property you plan to sell or by calling our office if the property is within St. Johns County. If the property is located outside of the county, the property appraiser’s office in the county where the property is located can provide that information. For more information, visit www.sjcpa.gov/portability. Leave this section blank if this is your first home purchase, first Florida home purchase, or if your previously owned property was not homesteaded.

  • For Non-Homestead Deferred Amount, leave this section blank if your potential property or new property is or will be homesteaded. This section is typically used for property owners who have owned an additional home in Florida for many years and are now looking to homestead that home. This can help them determine if they should keep the 10% non-homestead cap or remove the 10% cap and start again with the 3% homestead cap.
