Fla. Admin. Code R. 12D-17.0035 (2026)
Instructions and Calculations
(1) Rolled-back rate. Specific instructions for calculating the rolled-back rate are contained in the Truth in Millage (TRIM) compliance instructions for completing a Certification of Taxable Value (form DR-420, incorporated by reference in Rule 12D-16.002, F.A.C.). The calculation of the rolled-back rate must include all millages exclusive of voted debt service levies and millages in excess of the 10 mill cap pursuant to Section 200.071, F.S.
(2)(a) Percent increase over the current year rolled-back rate of tentative millage. The calculation is: current year aggregate tentative millage divided by the current year aggregate rolled-back rate, minus 1.00, times 100, equals the percent to publish in the Notice of Tax Increase advertisement. The actual calculation is:
(current year aggregate tentative millage/current year aggregate rolled-back rate) - 1.00 x 100 | = | percent to publish in the Notice of Tax Increase advertisement. |
(b) Percent increase over the rolled-back rate of final millage. The calculation is: current year final millage divided by the current year rolled-back rate, minus 1.00, times 100 equals the percent to state in the ordinance or resolution as required by Section 200.065(2)(d), F.S. The actual calculation is:
((current year final millage/rolled-back rate) - 1.00) x 100 | = | percent to state in resolution or ordinance |
(3) Taxing Authorities and School Districts: Calculation of proposed, tentative, and final budgets, proposed and final millage rates, and ad valorem proceeds. In calculating these figures, Section 200.065(2)(a)1., F.S., requires each taxing authority to use not less than 95 percent of the taxable value certified to it by the property appraiser. This is at least 95 percent of the gross taxable value appearing on line 4 of the form DR-420 or a Certification of School Taxable Value (form DR-420S, incorporated by reference in Rule 12D-16.002, F.A.C.).
(a) The calculation of the tentative budget or ad valorem proceeds is:
Line 4 of form DR-420 or form DR-420S x .95 x tentative millage rate | = | the absolute minimum of ad valorem proceeds to use for tentative budget purposes |
(b) The calculation of the final budget or ad valorem proceeds is:
Line 4 of form DR-420 or form DR-420S x .95 x final millage rate | = | the absolute minimum of ad valorem proceeds to use for final budget purposes |
(4) Budget summary advertisement. The advertised budget must remain in balance. The tentative millages stated in the budget summary advertisement must be the millages the taxing authority is proposing to levy, and must be tied to the anticipated ad valorem proceeds resulting from each millage. Each tentative millage must be displayed in the budget summary advertisement. However, each millage may be divided and allocated to one or more funds or budgets, provided it is readily apparent in the advertisement that the sum of the millages is less than or equal to the respective proposed millage. The proceeds must be displayed in the appropriate fund or budget to which they are to be deposited.
