Your 2026 Beaufort County Property Tax Bill: What to Check Before January 15
If you own a home in Beaufort County, your 2026 real property tax bill is either in your mailbox or on its way. The Beaufort County Treasurer says real property bills are sent by October 31 and due by January 15.
Before you pay, take five minutes to read it. One number on that bill (the assessment ratio) can make a big difference in what you owe, and this year there are a couple of changes worth knowing about. Here's what to look for, which deadlines matter, and what to do if something looks wrong.
When Beaufort County Property Taxes Are Due (and What Happens If You're Late)
Real property taxes in Beaufort County are due January 15. After that, the Treasurer's office adds penalties on a set schedule, according to its delinquency FAQ:
January 16: 3% penalty on current-year taxes
February 3: 10% penalty
March 17: 15% penalty
March 19: the account becomes legally delinquent under state law
April 1: a $250 fee is added and delinquent tax bills are generated
September 1: an additional $150 fee
If your mortgage has an escrow account, your lender usually pays this bill for you. It's still worth checking that the bill is correct, because the amount drives your escrow payment for next year.
You can look up your bill online through the Treasurer's Tax Document Lookup, including bills that were sent electronically.
The Most Important Number on Your Bill: 4% or 6%
South Carolina taxes homes at different assessment ratios depending on how they're used. According to the Beaufort County Assessor, a home that is the owner's primary residence is assessed at 4% of its appraised value, "providing proper application has been made." All other residential property, including second homes and rentals, is assessed at 6%.
The Beaufort County Auditor explains that you can find the ratio right on your real property bill: it shows "4.00%" for a primary residence or "6.00%" for a non-primary residence.
Why the ratio matters so much
The assessment ratio is multiplied by your appraised value to get your assessed value, and the millage rate is applied to that. Here's a simple illustration (example numbers, not your bill):
A home appraised at $400,000 at 4% has an assessed value of $16,000.
The same home at 6% has an assessed value of $24,000.
That's 50% more assessed value at 6%. On top of that, South Carolina exempts owner-occupied homes receiving the 4% ratio from property taxes for school operating purposes, according to the SC Department of Revenue's 2026 legislative update. Together, those two things are why a primary residence taxed at 6% by mistake can cost a homeowner a lot.
"I live here full-time, but my bill says 6%"
The 4% rate isn't automatic. You have to apply through the Assessor. Common reasons a full-time resident sees 6%:
You bought the home recently and haven't applied yet.
You applied, but some required documents were missing.
Only one spouse submitted documents. The Assessor asks for items from both owners and spouses.
The Assessor's important dates page shows the 4% special assessment application window runs from January 1 of the tax year through January 15 of the following year. In other words, for the 2026 tax year, you have until January 15, 2027.
How to Apply for the 4% Legal Residence Rate in Beaufort County
According to the Assessor's Exemptions and Discounts page, you'll need these items for you and your spouse:
A copy of your South Carolina vehicle registration(s)
A copy of your South Carolina driver's license or ID card
A copy of your most recently filed South Carolina income tax return (or an SSA-1099 Social Security benefit statement)
A copy of your trust agreement, if the home is held in a trust
You can apply online through the Assessor's Legal Residence Exemption Application, linked from that same page. Questions about an application can go to the Assessor's office at (843) 255-2400.
Think you qualified in an earlier year?
The Assessor accepts refund requests if you believe you were eligible for the 4% ratio before the year you were first approved. Approval isn't guaranteed, and you'll need supporting documents for the years you're asking about.
Military Homeowners: You May Qualify Even If Your Legal Residence Is Another State
This is one of the most-missed savings for service members stationed at MCAS Beaufort, MCRD Parris Island, or Naval Hospital Beaufort.
Under S.C. Code § 12-43-220, an active-duty service member whose permanent duty station is in South Carolina can qualify for the 4% owner-occupied ratio even if they keep their legal residence in another state. Beaufort County's Assessor asks military applicants to provide:
A copy of PCS orders and military/spouse ID
A copy of a current Leave and Earnings Statement (LES)
A copy of military ID for members and their spouses
If you're still planning your move, our PCS guide for MCAS Beaufort and Parris Island and our military homebuyer page walk through the buying side.
New This Year: The Homestead Exemption Rose to $75,000
The homestead exemption is a separate benefit from the 4% rate. Beaufort County's Auditor reports that, beginning with the 2026 tax year, the Homestead Exemption was raised from $50,000 to $75,000 under the state's SLASH (State Legislature Aiding in Saving Homes) program.
Who it's for, per the Auditor: homeowners who meet the age requirement or are 100% totally and permanently disabled or legally blind, have lived in South Carolina as full-time residents for at least one full calendar year, and already receive the 4% legal residence rate.
A few things to know:
If you already receive the homestead exemption, the Auditor says no further action is needed.
If you think you qualify but haven't applied, contact the Beaufort County Auditor at (843) 255-2500.
It's temporary for now. The SC Department of Revenue lists the extra $25,000 as a budget proviso that expires June 30, 2027 unless lawmakers renew it.
You'll see a new note on your bill. A separate 2026 proviso requires property tax notices to itemize any homestead exemption and include a SLASH notation showing how much your bill was reduced.
Other Things Worth Checking on Your 2026 Bill
You bought or sold a home this year
If you bought your home in 2026 and live in it full-time, make sure you apply for the 4% rate before the January 15, 2027 deadline. Your closing statement will usually show how taxes were prorated between buyer and seller.
Buyers who are paying the 6% rate on a non-primary home may also want to ask about the Assessable Transfer of Interest (ATI) exemption, which the Assessor says can reduce the taxable value of 6% property by up to 25% (but not below the current value on record). The Assessor says to apply before January 31 for the first year you claim it.
You disagree with your home's value
Beaufort County's last countywide reassessment was in 2023, and the next is scheduled for 2028, according to the Assessor. If you think your value is wrong, the Assessor's important dates show you can object between January 1 of the current year and January 15 of the following year, or within 90 days of receiving an assessment notice (but not both in the same tax year).
Your mailing address is wrong
Per the Assessor's FAQ, mailing address changes go through the Treasurer at (843) 255-2600.
