South Carolina Property Tax for New Homeowners: The 4% Rate and How to Apply
South Carolina taxes an owner-occupied home at 4% instead of 6%, but only after you apply. Who qualifies, the deadline, and how to file in Greenville and Spartanburg.
South Carolina property tax on an owner-occupied primary home is figured at a 4% assessment ratio, and the home is exempt from school operating millage. Without an approved legal residence application, a home is assessed at 6% with school operating millage included. The 4% rate is not automatic: you apply with your county assessor before the first penalty date for that year's taxes, which in Greenville County is January 15.
If you are closing on a new home in Greenville, Spartanburg, or anywhere else in South Carolina, the application is yours to file. Nobody files it for you.
4% vs. 6%: how South Carolina property tax changes on your bill
South Carolina property tax is the assessed value times the millage rate. The assessed value is the home's fair market value times an assessment ratio. Two things change when your home qualifies as your legal residence:
The assessment ratio drops from 6% to 4%. State law sets 4% for a legal residence and up to five contiguous acres, and 6% for all other real property not otherwise classified (S.C. Code § 12-43-220).
School operating millage comes off the bill. County assessors describe the 4% classification as including a credit that exempts the school operating tax. School debt millage, county millage, and city millage still apply.
An illustration using Greenville County's 2025 millage
Greenville County's 2025 millage sheet lists a school operating levy of 141.2 mills. Take a $400,000 home in a district with 250.1 total mills. These numbers are for illustration; your bill depends on your district, your appraised value, and credits.
At 6%: $400,000 x 6% = $24,000 assessed. $24,000 x 250.1 mills = $6,002 a year.
At 4%: $400,000 x 4% = $16,000 assessed. Without the 141.2 school operating mills, 108.9 mills apply. $16,000 x 108.9 mills = $1,742 a year.
That district carries no city or fire millage; most in-city bills run higher at both ratios.
In that example, filing one application is worth about $4,260 a year. Check your own district's millage on the county auditor's site before you budget.
Who qualifies for the 4% legal residence rate?
Under S.C. Code § 12-43-220(c), a home qualifies when all of these are true:
You own it, in whole or in part, by recorded deed or life estate. Spartanburg County also accepts a recorded bond for title.
You live in it as your legal residence. It is your domicile, and you are not claiming a legal residence anywhere else.
You owned and occupied it for some period during the tax year. A home that qualifies for any part of the year gets the 4% ratio for the whole year. You must still be domiciled there when you file.
You do not rent it for more than 72 days in a calendar year.
You applied before the first penalty date for the tax year in which you first claim it.
Second homes, investment properties, and homes rented beyond the 72-day limit stay at 6%. So does a home titled to an LLC or other company: the owner-occupant must be a person.
When to apply after you close on a new home
South Carolina taxes for a given year are billed in the fall and due by the first penalty date, generally January 15 of the following year. The application deadline follows the same calendar.
Closing in 2026: apply before the first penalty date for your 2026 taxes. In Greenville County, the application must be hand-delivered or postmarked by January 15. Because you owned and occupied the home for part of 2026, you can qualify for all of 2026.
Miss the deadline: Spartanburg County warns that failure to file and become qualified means an automatic 6% assessment. State law lets the county accept a late filing for reasonable cause, and an eligible owner can seek a refund, but neither is guaranteed. Call your assessor before you count on either.
The safe rule: file within a week of moving in. Do not wait for the first bill.
How to apply in Greenville and Spartanburg Counties
Greenville County
Greenville County mails a legal residence application after your deed is recorded.
Both spouses or co-owners sign it.
Return it to the Office of Real Property Services with a copy of each signer's South Carolina driver's license showing the new home's address.
Deliver it or have it postmarked by January 15.
Spartanburg County
Download the Application for Legal Residence Special Assessment from the county assessor's page.
Sign the sworn statement that the home is your legal residence.
File before the first penalty date for the tax year you are claiming. The county is clear that the owner files, not the mortgage company and not the closing attorney.
Questions go to the Spartanburg County Assessor at 864-596-2544, 366 N. Church Street.
Have these ready
Counties verify domicile with documents tied to the new address. Richland County, for example, requires, among other items, a South Carolina driver's license, South Carolina vehicle registration for every owner-occupant and spouse, and a South Carolina income tax return. Update your license and registration to the new address first; it makes the application straightforward to prove.
Other tax changes that come with a purchase
The 15% cap starts over. Greenville County notes that a sale is an assessable transfer of interest, which removes the 15% reassessment cap that applied before the transfer.
Proration at closing. Your closing attorney splits the year's taxes between seller and buyer. On new construction, ask what value the closing-year bill reflects. It may cover the lot or a partly built house, so budget for a higher first full-year bill.
Your escrow. If your lender escrows taxes based on a 6% estimate, send the approval letter to your servicer so the monthly payment is recalculated.
If you later rent the home
The 4% ratio depends on how you use the home, not only on owning it. If you move out and rent the home, or rent it more than 72 days in a year, you must notify the assessor within six months of the change. An owner who keeps the 4% rate after losing eligibility faces a penalty equal to 100% of the tax paid, plus interest, under § 12-43-220(c). Investors comparing buying versus building a rental should run their numbers at 6%.
Frequently asked questions
Is the 4% South Carolina property tax rate automatic?
No. You must apply with your county assessor. Until you do, the home is assessed at 6%.
Does my lender or closing attorney file the 4% application for me?
No. The owner files. Spartanburg County states that the owner-occupant is responsible, not the mortgage company or the closing attorney.
I closed in December. Can I still get the 4% rate for this year?
Yes, if you owned and occupied the home as your legal residence for some part of the year and you apply before the first penalty date for that year's taxes.
Can I get the 4% rate on a second home or a rental?
No. Only one legal residence qualifies, and a home rented more than 72 days in a calendar year does not qualify.
What happens if I apply late?
Expect the year to be billed at 6%. State law allows a late filing for reasonable cause and a refund for an eligible owner in some cases; your assessor decides.
