South Carolina Property Tax Appeal Deadline 2026: 90 Days from Notice
Updated March 2026
South Carolina gives you 90 days to appeal after an assessment notice. Contrary to a widely repeated myth, you are not locked out in the years between reassessments. Under state law you can challenge your value every year. What the five year cycle controls is when the county recalculates your value and mails a notice, not whether you are allowed to appeal.
South Carolina Property Tax Appeal Deadline: The 90-Day Rule
If you received an assessment notice, you have 90 days from the date of that notice to file a written objection (S.C. Code 12-60-2510).
Key Points:
- 90 days from YOUR notice date, not from January 1
- Written appeal required
- You can challenge the fair market value, the special use value, the assessment ratio, or the assessment itself
- Counties reassess on a five year cycle, which is when notices go out
What If You Did Not Get a Notice This Year?
You can still appeal. S.C. Code 12-60-2510 provides that in years when there is no notice of property tax assessment, the taxpayer may appeal the value at any time. The constraint is timing, not eligibility: an appeal submitted on or after the first penalty date applies to the following property tax year rather than the current one.
South Carolina property taxes are payable through January 15, and the first penalty attaches January 16 (S.C. Code 12-45-70 and 12-45-180). So the practical rule is:
- File before January 16 and your appeal applies to the current tax year
- File on or after January 16 and it still counts, but it applies to next year's taxes
This is the single most expensive misunderstanding in South Carolina property tax. Waiting five years for your next reassessment because you believe you have no other option means paying an inflated bill every one of those years.
Which Counties Reassess in 2026
Reassessment decides whether a notice lands in your mailbox this year, which sets whether you are on the 90 day clock or the January one. We are not going to publish a county list here, because the Department of Revenue does not maintain a public statewide schedule and counties can postpone an implementation year by ordinance. Every list you find online is somebody's reconstruction, and a wrong one sends you looking for a notice that was never coming.
Your county assessor's office will tell you in one phone call. It matters less than it used to, though: since you can appeal in any year, the reassessment schedule only changes which deadline applies to you, not whether you have one.
What Triggers a New Notice:
- Countywide reassessment
- New construction
- Improvements/additions

A real AppealDesk order, Beaufort County
In May 2026, a homeowner in Beaufort County ran the check. The county had their home on record at $392,000, while recorded sales of comparable homes supported about $340,541: an over-assessment of $51,459, worth roughly $580 per year if corrected. Their packet laid out the comparable sales, the forms, and the filing steps. Nobody at the county was ever going to run that check for them.
A deadline you meet with no evidence behind it is just paperwork. Comparable sales are what boards actually respond to, and pulling your county's number is where that starts.

Your South Carolina Action Plan
Step 1: Find Which Clock You Are On
- Got a notice this year? 90 days from its date
- No notice this year? You can still appeal, any time
- Want it to count for this year? File before January 16
- Filing later than that? It applies to next year's taxes
- Either way you are eligible - the cycle does not bar you
Step 2: Classification Check
- Primary residence? - Should be 4%
- Secondary home? - Should be 6%
- Often wrong - Easy fix
- Huge savings - If corrected
- Do this first - Before value appeal
Step 3: Build Evidence
- Local sales - Same area/type
- Property issues - All problems
- Storm history - If applicable
- Classification proof - If needed
- Professional help - Consider value
Step 4: File Smart
- Try informal first - Often works
- Written appeal - If needed
- Complete package - All evidence
- File by day 80 - Safety margin
- Track everything - Paper trail
The Bottom Line
If a notice arrived this year, the 90 day clock is the one that matters and it moves fast. If no notice arrived, you still have a right to appeal, and the date that matters is January 15.
Classification errors between primary (4%) and secondary (6%) residences offer the easiest wins. Beyond that, hurricane history, coastal changes, and the unique challenges of heirs property create numerous grounds for appeal.
The costly mistake in the Palmetto State is assuming the five year cycle locks you out. It does not. It only decides whether the county hands you a deadline or you have to know it yourself.
Critical Note: South Carolina does NOT limit appeals to reassessment years. With a notice, you have 90 days from the notice date, not from the assessment date. Without a notice, S.C. Code 12-60-2510 lets you appeal at any time, though an appeal filed on or after the first penalty date of January 16 applies to the following tax year. Check your classification (4% vs 6%), then build your value case.
