Ad Valorem Taxes vs. Non-Ad Valorem Assessments: What’s the Difference?
Ad valorem taxes are based on your property’s taxable value. The amount you pay is influenced by your property’s assessed value, applicable exemptions and assessment limitations (such as the Save Our Homes cap), and the tax rates set by local taxing authorities.
Non-ad valorem assessments, on the other hand, are not based on your property’s value. These assessments are typically charges for specific services or improvements that benefit your property, such as solid waste collection, fire services, or other local services. The amount and method used to calculate these assessments are determined by Hillsborough County government or taxing authority that imposes them like stormwater management.
Remember: The Property Appraiser determines your property’s value and administers eligible exemptions and assessment limitations, but does not set tax rates or non-ad valorem assessments.
