The millage rate is the tax rate set by each taxing jurisdiction, such as the county, school district, or municipality.

The South Carolina Association of Counties publishes the Millage rates around the state which can be found here.

The value of a mill represents the amount of property tax revenue one mill will generate.  A mill equals 1/1000 of the assessed value of the property subject to property taxes. 

For example, if the assessed value of a property totals $100,000 the value of a mill is $100.

 The school operating millage table shows the value of a school operating mill for each school district.  

Pursuant to S.C. Code Section 6-1-320, a local governing body may increase the millage rate imposed for general operating purposes above the rate imposed for such purposes in the preceding tax year by the increase in population and inflation for the previous calendar year.  If either component is negative, that component is deemed to be zero.  

For additional information, see the millage rate increase limitation page.

The State reimburses local jurisdictions to help offset the reduction in property tax revenue due to property tax exemptions.  Property tax reimbursements include:

School operating Exemptions (Tier I, Tier II, and Tier III)

Manufacturers Depreciation

Manufacturers Exemption

Merchants Inventory

For information on the amount for each reimbursement see Property Tax Reimbursement Page.

• Tier I – reimbursement for first $100K residential school operating exemption.  The reimbursement is capped at $249,069,749.91.
• Tier II – reimbursement for $50K property tax exemption from all millage for homeowners 65 and older or disabled.  The school operating portion of Tier II is capped at $80,892,728.71.
• Tier III – reimbursement for remaining appraised value from school operating millage (this exemption created by Act 388).  The reimbursement is based on formula.  The total reimbursement increases on an annual basis by population growth plus inflation.  Annually, each school district receives the total reimbursement from the prior year plus a pro-rata share of the increased amount based on student population relative to the total student population statewide.  Any county that does not receive a minimum of $2.5M, will receive extra funds to raise the reimbursement to $2.5M.  If there are multiple school districts within a $2.5M minimum county, the extra funding is distributed based on student population.
