Understanding Horry County Millage Rates
Horry County property taxes are calculated based on three primary factors: the Fair Market Value, the Assessment Ratio, and the Millage Rate. In South Carolina, one "mill" represents $1 of tax for every $1,000 of assessed property value.
Key Components:
Fair Market Value: This is the value determined by the Horry County Assessor's Office during the last reassessment cycle.
Assessment Ratio: Most homeowners living in their primary residence qualify for a 4% ratio. Secondary homes, rental properties, and commercial buildings are typically taxed at a 6% ratio.
Millage Rate: This is the total of various taxing entities including Horry County Government, Horry County Schools, and any applicable municipal rates (like Myrtle Beach, Conway, or North Myrtle Beach).
Act 388: Passed by the SC Legislature, this provides a "School Tax Credit" that exempts primary residences (4% properties) from the school operating portion of the property tax bill.
Example Calculation (2024 Estimates):
If you own a primary residence in Horry County valued at $300,000:
Assessed Value: $300,000 x 4% = $12,000.
Gross Tax (Assuming 210 Mills): ($12,000 x 0.210) = $2,520.
Act 388 Credit: If school operating mills are 120, your credit would be ($12,000 x 0.120) = $1,440.
Final Bill: $2,520 – $1,440 = $1,080 (plus applicable fees).

// 3. Act 388 Credit Logic
// In Horry County, School Operating Mills typically make up a large portion of the millage.
// For this calculator, we estimate the school operating portion at roughly 55% of the total millage
// if Act 388 is checked and it's a 4% property.
var credit = 0;
if (useAct388 && ratio === 0.04) {
// Average school operating millage portion in Horry County is approx 110-130 mills.
// We will calculate the credit based on a standard estimated school operating rate (approx 125 mills)
// or cap it at 60% of total millage to stay realistic.
