The South Carolina Office of Revenue and Fiscal Affairs has released county millage rate limitations for FY 2025-26. County population estimates—one of the two components that make up the millage rate increase limitation prescribed in Section 6-1-320(A)(1)(opens in a new tab)—were recently released by the U.S. Census Bureau. The other component—the Consumer Price Index (CPI) increase of 2.95%—was released in February.
The millage rate increase limitation for FY 2026 will be the total of the percentage increase in your county's population estimate from 2023 to 2024 plus the 2.95% CPI. For purposes of the millage cap, if your county's population decreased, you are deemed to have zero population growth for FY 2025-26.

Counties may include any unused capacity from the previous three years to calculate their FY 2026 Millage Increase Limitation. SCAC does not know what unused capacity your county may have. The three-year lookback for FY 2023 to FY 2025 can be viewed here.(opens in a new tab)
Section 6-1-320(B)(opens in a new tab) provides that the millage rate limitation may only be suspended and the millage rate increased upon a two-thirds vote of the county governing body and ONLY for the following purposes:
The millage rate limitation does not affect millage that is levied to pay bonded indebtedness or payments for real property purchased using a lease-purchase agreement or used to maintain a reserve account. It also does not affect millage imposed to pay bonded indebtedness or operating expenses of a special tax district as prescribed in Section 4-9-30(5).
