The Marlboro County tax map is available free online through two county portals: an interactive GIS map at marlborosc.wthgis.com for parcel boundaries and a property record search at qpublic.net/sc/marlboro for assessment and ownership data. Between them you can pull up acreage, assessed value, land use classification, and the current owner of any parcel in the county by searching an address, an owner name, or a Tax Map Sequence (TMS) number. Both sites carry disclaimers that the data is informational and may lag behind current records, so verify anything you plan to use in a closing or a legal filing with the Tax Assessor’s office.
How to Open the County Portals
The GIS mapping portal is hosted by WTH Technology at marlborosc.wthgis.com. It loads in any standard browser and needs no account or login.1Marlboro County, SC GIS. Marlboro County SC Map Use this one when you want to see parcel boundaries drawn on a map and view the land relative to roads and neighbors.
The qPublic portal at qpublic.net/sc/marlboro, run through Schneider Geospatial, is the companion tool for record data rather than map views. It’s the better stop for assessment figures, ownership history, and tax detail. The site itself warns that its data is “intended for information purposes only” and “is not warranted,” so treat what you find as a research starting point.2qPublic.net.

Searching by TMS Number, Name, or Address
Every parcel in the county has a Tax Map Sequence number, usually called a TMS number. It’s the code that ties ownership records to a specific location on the tax maps, and the assessor’s office keeps both sides of that link current.3Williamsburg County, SC. Terms and Definitions – Section: Tax Map Number (TMS) or Parcel ID Number You’ll find your TMS on your South Carolina property tax bill or on a recorded deed.
Don’t have the TMS handy? Both portals also accept owner name and street address. The WTH GIS search is flexible enough to take a partial address or an intersection and narrow the results from there. Once you find the right parcel, click it. The map centers on the property, highlights its boundary, and opens the data card for that lot.
What the Map Shows for Each Parcel
Clicking a parcel brings up the core information most searches are after: total acreage, the assessed market value from the most recent county reassessment, the land use classification, and the current owner of record. The classification tells you whether the assessor treats the parcel as residential, agricultural, or commercial, and that label decides which assessment ratio applies at tax time.
The GIS portal layers additional map data on top of the parcel lines. Depending on what the county has switched on, that can include aerial photography and topographic features useful for sizing up terrain. Flood risk is a separate lookup: FEMA runs the official Flood Map Service Center at msc.fema.gov for hazard maps tied to the National Flood Insurance Program.4Federal Emergency Management Agency.

Why the Classification on the Map Matters
The classification code isn’t just a description. South Carolina’s constitution sets a different assessment ratio for each class of property, and the ratio decides how much of your market value the county actually taxes.
- Owner-occupied residence (plus up to five acres): 4% of fair market value
- Agricultural land, individual or qualifying small-corporation owner: 4% of agricultural use value
- Agricultural land, corporate owner: 6% of agricultural use value
- Commercial, rental, and all other real property: 6% of fair market value
- Manufacturing and utility property: 10.5% of fair market value
Your tax bill is the assessed value (market value times the ratio above) multiplied by your local millage rate.5South Carolina Legislature. South Carolina Code 12-43-220 – Classifications and Assessment Ratios A $200,000 home taxed as an owner-occupied residence at 4% has an assessed value of $8,000; the same home classified as a rental at 6% sits at $12,000. If the map shows the wrong classification for your parcel, that’s worth fixing.
When the Assessed Value on the Map Changes
South Carolina law requires each county to reappraise all real property once every five years. Valuations must be finished by the end of December in the fourth year, and any owner whose value or classification changed by $1,000 or more receives a notice. The new values take effect the following (fifth) year. A county can push implementation back by one tax year through a local ordinance, but the schedule for the next cycle doesn’t move.6South Carolina Legislature. South Carolina Code 12-43 – County Equalization and Reassessment – Section: 12-43-217
Between reassessments the number on your tax map generally stays put unless something changes it: new construction, a transfer, or a successful appeal. A neighbor’s sale price doesn’t automatically pull your assessed value up until the next countywide reappraisal.
If the Map Data Looks Wrong
You can challenge a value or classification that appears incorrect, but the deadlines are strict and missing one forfeits the appeal.
In a reassessment year, you have 90 days from the date on the assessor’s notice to file a written objection. In a non-reassessment year, when no notice goes out, you can still object, but the filing must be in writing and must reach the assessor before the first penalty date (January 15 in most cases).7South Carolina Legislature. South Carolina Code 12-60-2510 – Property Tax Assessment
Once the objection is filed, the appeal moves through set stages:
- Assessor conference. If the assessor disagrees with your objection, the office schedules a meeting within 30 days.
- Written protest. If the conference doesn’t settle it, you file a formal written protest within 30 days, and the assessor responds in writing within another 30 days.
- Board of Assessment Appeals. If you still disagree, you appeal to the county board within 30 days of the assessor’s response. Both sides exchange evidence at least 15 days before the hearing.
- Administrative Law Judge. If the board rules against you, you have 30 days to request a contested case hearing before an ALJ.
The strongest grounds are a market value that comparable sales won’t support, an incorrect classification, or a factual error in the records such as wrong acreage or a building that no longer exists. Bring recent comparable sales, a professional appraisal, or documentation of the specific error. Arguments about the millage rate or how tax revenue is spent won’t move the assessor or the board, because those questions sit outside their authority.
When You Need More Than the Online Map
For a certified copy of a tax map, a boundary question the portals can’t answer, or a correction to a property record, the Marlboro County Tax Assessor’s office in Bennettsville is the authoritative source. The office can be reached at (843) 897-2009, and the mailing address is PO Box 62, Bennettsville, SC 29512.8South Carolina Association of Counties. Marlboro County Directory Staff can produce physical copies of tax maps for a fee that varies with the size and detail of the request.
South Carolina’s Freedom of Information Act also lets you request public records in writing, including GIS data held by county offices.9South Carolina Attorney General. Freedom of Information Act (FOIA) If you’re after bulk parcel data or a complete dataset rather than a single map, a written FOIA request to the assessor’s office is the route to take.
