South Carolina taxes the home you live in at a 4% assessment rate. Second homes, rentals and land use 6%. Owner-occupants also skip school operating millage. In my Greenville example below, that turns a $7,956 bill into about $3,045, but only after you file the legal residence application with the county.
I’m Chris Horrell, born and raised in Greenville. Every year I talk to new homeowners who never filed for the 4% and paid the higher bill for a year or more. Here’s how the system works in Greenville and Spartanburg counties, and what to do the week you close.
What is the difference between the 4% and 6% assessment rate?
The assessment rate decides how much of your home’s market value gets taxed. Under SC Code Section 12-43-220(c), your legal residence and up to 5 contiguous acres are assessed at 4% of fair market value. Other real property, including second homes and rentals, is assessed at 6%.
That 2 point gap sounds small. It isn’t. Spartanburg County’s Assessor warns that eligible owners who don’t file “could make their tax liability more than three times higher” (Spartanburg County Assessor). The reason is the next piece: the 4% comes bundled with a school tax break.
📍 The rental rule: The home can’t be rented for more than 72 days in a calendar year and still keep the 4% rate.
“Your primary residence is often taxed in a different category than a second home or even an investment property. So, if you buy a Lake Keowee place as a second home, for example, or you simply haven’t filed the paperwork yet, your bill may be higher than you expect.”

How do I apply for the 4% assessment rate?
You apply with your county, not the state. In Greenville County it’s the Office of Real Property Services, which posts an online Legal Residence Special Assessment Application. In Spartanburg County it’s the Assessor’s Office. State law says you must file before the first penalty date for the tax year you first claim, which in practice means January.
📍 Deadline: Spartanburg County listed January 15, 2025 as the deadline for tax year 2024. Taxes for a year come due the following January, so a home you buy in 2026 needs the application in before the January 2027 due date.
📍 Documents the law asks for: A signed certification that this is your legal residence and domicile, your most recent SC income tax return, and SC vehicle registrations at the same address. The county can ask for more.
📍 Greenville County specifics: Greenville County mails the application after your deed is recorded. Both spouses or co-owners sign it, and you include copies of both SC driver’s licenses showing the property address.
Moving from out of state? Get your SC driver’s license and car tags switched early. Those documents are what prove the house is your home.
What is the school operating millage exemption?
Owner-occupied homes that get the 4% rate are exempt from all property taxes imposed for school operating purposes under SC Code Section 12-37-220(B)(47). You still pay school debt millage, which repays school construction bonds.
This is a big deal because schools are most of the bill. The SC Department of Revenue says about two-thirds of county-levied property taxes support public education. In Greenville County’s 2025 millage sheet, Greenville County Schools levies 189.7 mills: 141.2 for operations and 48.5 for debt (Greenville County Auditor).
How much does the 4% rate actually save?
On a hypothetical $400,000 home inside the City of Greenville, the 4% rate plus the school operating exemption brings the estimated bill to about $3,045, compared with about $7,956 at 6%. That uses Greenville County’s 2025 total of 331.5 mills for city district 500. Your district and final bill will differ.
Here’s the math. A mill is $1 of tax per $1,000 of assessed value. The county’s own formula is assessment times millage equals tax bill (Greenville County Real Property Services).
- Owner-occupied (4%): $400,000 x 4% = $16,000 assessed. 331.5 mills minus 141.2 school operating mills = 190.3 mills. $16,000 x 0.1903 = about $3,045.
- Not owner-occupied (6%): $400,000 x 6% = $24,000 assessed. $24,000 x 0.3315 = about $7,956.
This is a hypothetical value for illustration. Real bills can include credits, fees and a different tax district. Run your own numbers on our mortgage calculator and check the county’s estimator before you write an offer.
What is the SC homestead exemption for 65 and older?
The homestead exemption removes the first $50,000 of your home’s fair market value from county, municipal, school and special assessment taxes. You qualify at age 65 by December 31, if you’re totally and permanently disabled, or legally blind, and you need at least 1 year of SC residency. It stacks on top of the 4% rate.
In the example above, a qualifying owner would be taxed on $350,000 instead of $400,000, cutting the estimate from about $3,045 to about $2,664. Greenville County says you don’t reapply every year, only after the owner dies or you move.
📍 Watch the Statehouse: A bill to raise the exemption, S.768, passed the Senate 44-0 in February 2026. As of October 2026 it was still in the House Ways and Means Committee, so $50,000 is the current amount.
How does the 15% reassessment cap work?
South Carolina limits how much a property’s appraised value can rise at each countywide reassessment to 15%. New construction or remodeling can still reset the value. The catch for buyers is that the cap comes off when the property sells. Your purchase triggers a point-of-sale reassessment, so your taxable value resets to current market value.
County guides, like this one from Berkeley County, explain that state law requires removing the 15% cap “when an assessable transfer of interest occurs.” In plain words: the seller’s tax bill is not your tax bill. A long-time owner may be paying on a value capped years ago.
When are Greenville and Spartanburg counties reassessed?
State law requires counties to reappraise every 5 years. Greenville County completed its countywide reassessment for tax year 2025 and lists 2030 as the next one. Spartanburg County says its next reappraisal will be implemented in 2028.
When values rise in a reassessment year, local governments adjust millage under state rollback rules, so a higher value doesn’t automatically mean the same percentage jump in your bill. If you think the county’s value is wrong, both counties have an appeal process with deadlines on the notice. Don’t sit on it.
🛡️ Why It Matters
I spent my career as a Greenville County Sheriff’s Deputy, and I learned that paperwork protects people. A missed form is a quiet problem. Nobody knocks on your door about it. You just get a bill that’s more than double what your neighbor pays for the same house.
When my clients close, I remind them to watch for the application, file it, and keep a copy.
