A 3% surcharge is levied against your property tax amount, not the value of the property. For example, a CPA surcharge of 3 percent on a real property tax bill of $1,000 would be $30, or 3 percent of $1,000, per year.  Note:  the numbers below are provided as an illustration.  Actual CPA surcharges depend on assessed values, tax rates, and residential exemptions, which are set on an annual basis.

1. Owner-Occupied Residential Property

2. Residential Property, Not Owner-Occupied

3. Mixed-Use Property, Not Owner-Occupied

4. Commercial Property
