Frequently Asked Questions

Why do we pay property tax?

Property tax is collected by local governments to provide for the many services most of us take for granted. Schools, police and fire protection and public libraries are possible because of revenue from the property tax. We are all asked to pay our fair share of the cost of these services by paying tax in proportion to the value of our property.

How is property taxed?

South Carolina's Constitution requires that property be taxed in accordance with the properties value. From the time your property is added to the tax rolls, the tax assessment does not change unless physical changes have been made or a reassessment program is implemented or an assessable transfer of interest occurs. The most recent reassessment was implemented for the 2014 tax year. The next countywide reassessment is scheduled to be implemented for the 2019 tax year. In determining the County's annual budget, County Council sets the tax levy each year. The rate is reflected in "mills" or "millage rate", and one mill is one thousandth of one dollar (.001). The County Assessor appraises real property, the Auditor maintains the property tax rolls and calculates individual property taxes, and the County Treasurer collects the property taxes. All property is appraised at its fair market value and is multiplied by the appropriate assessment ratio for the type of property. All real property is assessed at a four percent (owner occupied primary residence) four or six percent (farm) or a six percent (all other) rate. Therefore, property taxes are determined by multiplying the fair market value, times the assessment ratio, times the millage rate. For example, the tax on your legal, full-time residence in Horry County is determined this way:

A home located in the unincorporated area of Horry County (qualified legal residence):


$125,000 Fair market value of home
x   4% Assessment ratio (4% if qualified legal resident)
$5,000 Assessed value
x   .2026 Countywide millage rate 1
$1,013.00 Taxes
-   601.00 Tax credit - (5,000 @ .1202) School operations
$412.00 Taxes Due


A commercial property located in the unincorporated area of Horry County:

$125,000 Fair market value of home
x   6% Assessment ratio
$7,500 Assessed value
x   .2026 Countywide millage rate 1
$1,519.50 Taxes Due


1 County Millage: 45.2; School: 130.2; Fire: 21.2; Waste Mgmt: 6.0;

Although a taxpayer receives just one property tax bill, there are other agencies that utilize that one tax bill to collect their own taxes. These agencies are itemized out on your bill, which include the School District, municipalities, special tax districts, etc. Any increase by any of these agencies will result in an increase to the overall tax bill.

How do I register my mobile home?

A $5.00 registration fee (if registered within fifteen (15) days of purchase, if not a $5 penalty will be added) must be paid to the Horry County Tax Assessors Department prior to issuance of building permit. All taxes must be paid on any pre-owned manufactured home before it can be registered and mobile home decal or moving permit issued. Payment may be made by cash OR check for the full amount.
