Property Tax at Surfside Beach: The 4%-vs-6% Rule Explained
South Carolina doesn't tax every home the same way -- how a property is used changes its assessment ratio, and that single distinction moves a Surfside Beach tax bill more than almost any other variable a buyer controls. Here's how the math actually works, and where current sourcing runs into real gaps.
Assessed Value Is Not Market Value in South Carolina
Unlike states that tax a home at its full appraised market value, South Carolina taxes real property on an assessed value equal to a set percentage of that market value, and the percentage depends on how the property is legally used. A property occupied by its owner as a primary legal residence is assessed at 4% of fair market value. A property that is not the owner's primary residence -- a second home, a long-term rental, a short-term vacation rental, or any investment property -- is assessed at 6%. That gap sounds small as a percentage, but it isn't small in dollar terms: on a $300,000 property, 4% produces a $12,000 taxable assessment while 6% produces an $18,000 taxable assessment, a 50% larger tax base for the identical house before any millage rate is even applied.
The 4% rate is not automatic. An owner has to affirmatively file for South Carolina's legal-residence exemption with the Horry County Assessor's Office and provide documentation -- typically proof the property is the owner's actual primary residence, such as a South Carolina driver's license or voter registration showing that address, plus confirmation the owner isn't claiming a similar exemption anywhere else. Buy a home here intending to live in it full-time and forget to file the paperwork, and the county will likely default the property to the 6% investment rate until the exemption is processed -- a real, avoidable cost that has nothing to do with the home's actual use.
What the 6% Rate Means for a Vacation-Home or Rental Purchase
Anyone buying at Surfside Beach specifically to run it as a vacation rental or hold it as a non-primary second home should model the tax bill at the 6% rate from day one, not the 4% rate they may have seen quoted for a comparable owner-occupied property nearby. This is one of the more common pricing mistakes buyers make in South Carolina generally: pulling a prior owner's tax bill off a listing sheet without checking whether that owner claimed the 4% owner-occupied exemption. If the prior owner lived there full-time and the new owner intends to rent it out, the actual bill under new ownership at 6% will run noticeably higher than the number printed on the listing -- sometimes by thousands of dollars a year depending on the assessed value and local millage.
This distinction interacts directly with Surfside Beach's own zoning rules, since the town restricts short-term rentals under 30 days to only its R3 and C3 zoning districts. A property outside those districts generally can't be legally run as a nightly vacation rental at all regardless of the tax rate paid on it -- so a buyer weighing a 6% investment-property tax bill against expected rental income needs to first confirm the parcel actually sits in a zone where that rental model is legal.
Millage: Where Current Sourcing Genuinely Disagrees
Once the assessment ratio produces a taxable value, that value is multiplied by a millage rate -- essentially dollars of tax per $1,000 of assessed value -- set separately by Horry County and by the Town of Surfside Beach, and added together for the total bill (a specific parcel may also carry additional special-district or school-district millage). This is where this page has to be honest about a real conflict in the sourcing: a property-tax aggregator (Ownwell) states Surfside Beach's own municipal millage at roughly 60.5 mills and Horry County's countywide millage at roughly 175.8 mills. Separately, the Town of Surfside Beach's own FY2026-27 budget materials describe the municipal millage as held flat at 43 mills for that fiscal year, following a budget approved June 10, 2025 that took effect July 1, 2025.
These two figures -- roughly 60.5 mills from the aggregator and 43 mills from the town's own budget messaging -- do not reconcile cleanly, and this page is not going to pick one and present it as fact. It's possible the aggregator's figure reflects a different fiscal year, includes an additional district levy the town budget summary doesn't, or is simply built on stale data; it's also possible the town's 43-mill figure omits a component the aggregator's number includes. Either way, don't budget a Surfside Beach property tax bill off either number in isolation -- pull the actual current millage breakdown for the specific parcel's tax district directly from the Horry County Auditor's Office, which is the authoritative source for the figure that will actually appear on a bill.
A Real, Confirmed Reference Point: The Ownwell Median
Despite the millage disagreement above, one set of figures from the same aggregator is internally consistent and worth citing as a reference point, not a guarantee: a median Surfside Beach home value of $250,120 producing a median annual property tax bill of $2,137, for a median effective tax rate of about 1.19%. That effective rate is meaningfully higher than both the South Carolina statewide median of 0.72% and the U.S. national median of 1.02%, which is consistent with a small coastal town that likely has a mix of owner-occupied and non-owner-occupied (6%-assessed) properties pulling its blended effective rate upward compared to the state as a whole.
A 1.19% effective rate on, for example, a $400,000 purchase would suggest a rough annual bill in the neighborhood of $4,700 -- but that's a back-of-envelope extrapolation from a median figure for a different home value, not a quote, and it assumes the purchaser's specific assessment ratio, exemptions, and millage district match the aggregator's blended average, which they may not. Use it as a sanity check on a specific parcel's actual bill, not a substitute for pulling that bill directly from the county.
South Carolina's Homestead Exemption for Seniors and Disabled Owners
Separate from the 4%-vs-6% assessment-ratio rule, South Carolina runs a statewide homestead exemption program that exempts the first $50,000 of a legal residence's fair market value from property tax for owners who are age 65 or older, totally and permanently disabled, or legally blind, administered through the county auditor's office. Given Surfside Beach's demographic skew toward retirees -- aggregator data (not an official Census figure) puts the town's median age around 55.4, with a meaningful share of residents at or past typical retirement age -- this exemption is a genuinely relevant, real cost-reduction tool for a share of the town's owner-occupied households, not a marginal footnote. It applies on top of, not instead of, the 4% owner-occupied assessment ratio for those who qualify for both.
This page did not independently confirm the current dollar-for-dollar tax savings this exemption produces at Surfside Beach's specific millage rate, since that depends on which of the two disputed millage figures above turns out to be current. Eligible owners should apply directly through the Horry County Auditor's Office, which can calculate the exact savings for a specific parcel.
Practical Steps Before Closing
Before making an offer at Surfside Beach, pull three things directly from Horry County rather than relying on a listing sheet or an online aggregator: the property's current assessed value and which ratio (4% or 6%) it's currently taxed under from the Assessor's Office, the exact current millage for that parcel's specific tax district from the Auditor's Office, and confirmation of whether any exemptions (legal residence, homestead for seniors/disabled) currently apply and whether they'd transfer or need to be re-filed under new ownership. If the purchase is intended as a primary residence, file for the legal-residence exemption promptly after closing rather than assuming it carries over automatically from the prior owner -- it generally does not.
If the purchase is intended as a rental or second home, budget at the 6% rate from the start and separately confirm with the Town of Surfside Beach's Planning, Building & Zoning Department whether the specific parcel sits in the R3 or C3 zoning district required for legal short-term rental operation, since a property taxed as an investment property but zoned in a way that prohibits short-term rentals is a genuinely worse outcome than either fact alone would suggest.
