The 2026 proposed and 2025 final millage of every levy on an Orlando bill, rebuilt from the Property Appraiser's detailed tables for all twenty of the city's tax-roll codes (each adds up to the published total), with the homestead exemption, Save Our Homes, the 10% non-homestead cap, the stormwater fee and the early-payment discounts applied.

   Checked every state read from a withholding or payroll document for a one-year lag. Only Arkansas lags (already declared as the 2025 indexing). Missouri, Oregon, Illinois and Michigan re-index each year and their 2026 withholding figures are the 2026 ones: none repeats the 2025 return's figure, and where we read the 2025 withholding document too (Missouri, Oregon, Michigan) it matched the 2025 return, so these states withhold on the current year. Connecticut, Hawaii, Iowa, Mississippi and Oklahoma set their figures in statute; Maryland's indexed deduction and Kentucky's come from other documents.
