How do South Carolina property taxes work when I buy a home?
By Joe Caleca, NMLS 2302900 · Updated October 22, 2026
Short answer
In South Carolina, the home you live in is assessed at 4% of its value, and it skips school operating taxes. A second home or rental is assessed at 6%, without that break. You have to apply for the 4% yourself. And when you buy, the county reappraises the home, so the seller's bill may not be yours for long.
When someone asks me what the taxes will be on a house, the first thing I do is pull the most recent tax bill. Most of the time, that’s the best starting point. But in South Carolina, two things can make your bill different from the seller’s. How you use the house, and the sale itself.
4% vs. 6%
South Carolina taxes a home on an assessed value, and the state sets that value by how the home is used. The house you live in gets two breaks. A second home or a rental gets neither.
| The home you live in | Second home or rental | |
|---|---|---|
| Assessed at | 4% of market value | 6% of market value |
| School operating taxes | Exempt | You pay them |
| How you get it | Apply with your county assessor | Automatic |
| Break after you buy | Already the lower rate | Up to 25% off the new value, if you apply |
| Greenville County deadline | January 15 | January 30 |

The school break covers school operating taxes only. You still pay school debt, county, and city taxes on the home you live in.
So when someone buying a second home or an investment property asks me about taxes, I tell them that 6% sounds like a small bump from 4%. On a real bill, it isn’t. Two things stack. The assessed value goes up by half, and the school operating taxes come back. Before you budget, ask the county or me to run the taxes on that exact house both ways.
It works in reverse too. If the seller rented the house out and you’re going to live in it, your bill can come down once your 4% is in place.
For second homes and rentals
The 25% break can't take the value below where it was before the sale, and it stays in place while the home stays at 6%. Like the 4%, it isn't automatic. You have to apply. The statute says by January 31, and Greenville County's calendar says January 30, so go by the earlier date.
Applying for the 4%
Buying the home you'll live in? Apply for the 4% by January 15.
That's Greenville County's date: hand delivered or postmarked. Other counties set their own. Put it on your list the week you get your keys.
The 4% isn’t automatic. You apply with your county assessor after you buy and move in, with proof that this is your only legal residence. The county lists the documents on its form and won’t process an application that’s missing them.
Generally, the county won’t give you the 4% for a tax year unless you applied before that year’s penalty date in January. If you move in within 90 days of buying, the 4% reaches back to the day you took ownership, as long as you apply in time. Once you’re approved, you don’t reapply while the home stays your legal residence.
This is the step I see people forget the most. They close, they move in, life gets busy, and nobody tells them the county is waiting on a form.
Your bill resets
South Carolina caps how much a countywide reappraisal can raise a home’s value at 15% over 5 years. A sale lifts that cap. The county resets the value to market, as of December 31 of the year the home sold.
When I estimate your taxes, I start with the most recent bill. If the seller lived in the home, that’s the number I use. It’s the same number your closing attorney uses to split the year’s taxes, and the one your lender uses to set up your escrow. If the seller had it as a second home or rental, I do the math at 4%. That bill is right for closing. The reset shows up later, because South Carolina pays taxes a year behind.
- June 2026You close. Taxes are split using the seller's bill. Escrow starts on that bill.
- Late October 2026The 2026 bill arrives, still on the old value. Due January 15, 2027.
- December 31, 2026The county sets the home's new value at market.
- Late October 2027The 2027 bill arrives on the new value. Due January 15, 2028. This is where the jump shows up.

If the seller owned the house for a long time, that 2027 bill can come in noticeably higher, because their value was capped and yours isn’t. So budget for the reset from day one. Ask me for a second estimate at today’s value, and you’ll know what’s coming before it shows up in your payment.

How escrow works
Most loans come with an escrow account. It’s a savings account for your taxes and insurance, built into your monthly payment. When the bills come due, your servicer pays them from it.
At closing, you put money in to get it started. Federal rules let your servicer keep a cushion of up to one-sixth of a year’s escrow payments, about two months. How much you put in at closing depends on when your next tax and insurance bills are due.
Once a year, your servicer reviews the account. If the real tax bill came in higher than the estimate, the account comes up short. Your servicer either asks you to pay the shortage or spreads it over 12 months or more, and your monthly payment goes up to cover next year. That’s the surprise people call me about. Often it’s the reset bill landing for the first time.
Before you sign
- Pull the most recent tax bill on the house.
- Find out how the seller used it: primary home, second home, or rental.
- Ask for a second estimate at today’s value, so you know what the reset might do.
- After closing, apply for the 4% if it’s your primary home, or the 25% break if it’s a second home or rental.
- Plan for the first escrow review, so a higher bill doesn’t catch you off guard.

More questions
Do I have to apply for the 4% rate every year?
No. You apply once, after you buy and move in. The South Carolina Department of Revenue says no new application is needed while the home keeps meeting the rules, which means it stays your legal residence. If that changes, like you move out and rent the house, it no longer qualifies for the 4%. If you buy a different home later, you apply again for the new one.
Can a second home or a rental ever get the 4% rate?
No. In South Carolina the 4% is for your legal residence, the one home you live in. A vacation home, a second home, or a rental is assessed at 6%, and it pays school operating taxes too. If you're buying a second home, plan your budget on the 6% from day one, and ask me to run the taxes on the specific house before you write an offer.
I'm moving to South Carolina from another state. Does this apply to me?
Yes, once the South Carolina home is your legal residence. When you apply, you certify that it's your only legal residence and that no one in your household claims residency in another state or the 4% on another home. These rules are South Carolina only. North Carolina, Michigan, and Florida each handle property taxes their own way, so don't carry a South Carolina number into a move to any of them.
Why did my mortgage payment go up a year or two after I bought?
Most of the time it's the escrow account. Your lender set it up on the seller's last tax bill, which was the right number at closing. Then the county reappraised the home after the sale, and the new bill came in higher. At the yearly review, the account came up short. Federal rules let your servicer ask you to pay the shortage or spread it over at least 12 months, and your monthly payment rises to cover the new bill going forward.
What if I miss the deadline to apply for the 4%?
Apply anyway, and call your county assessor right away. Generally, the county won't give you the 4% for a tax year unless you applied before that year's penalty date in January. In Greenville County, that means hand delivered or postmarked by January 15. Each county runs its own application and deadline, so check with yours. The sooner you file, the sooner the right ratio shows up on your bill.
Who do I call to check the taxes on a house?
Start with the county. The assessor's office handles the value and the 4% application. The treasurer or tax collector sends and collects the bill, and many counties let you look up a parcel's recent bill online. Your closing attorney will see the tax figures too. And you can always text or call me before you make an offer. I'll pull the bill and tell you what I see.
