SC Property Tax Protest Deadline: 90 Days From Notice Date
South Carolina property owners have exactly 90 days from the date printed on their assessment notice to file a written protest. This deadline applies to all property types, including duplexes, triplexes, and small apartment buildings.
The 90-day window starts ticking from the notice date, not from when you first opened the envelope or realized your assessment increased. If the 90th day falls on a weekend or state holiday, the deadline extends to the next business day.
Missing this deadline means your assessment becomes final. No informal phone calls or conversations with county staff count as protests. Only written submissions filed within the 90-day window preserve your appeal rights.
Most SC counties mail assessment notices between January and March each year. For 2026 assessments, owners who received notices in February have until late May to protest, while March notices carry deadlines into June.
Required Documentation for Multifamily Assessment Challenges
Strong protests require evidence that supports your position on market value. County assessors review hundreds of appeals, so clear documentation makes your case more compelling than general complaints about high taxes.
Market Value Evidence:
- Recent comparable sales of similar multifamily properties within one mile
- Current rent rolls showing actual income versus assessor assumptions
- Repair estimates for deferred maintenance or needed capital improvements
- Photos documenting property condition issues that affect value
Income Approach Documentation:
- Actual operating expenses from the previous 12 months
- Vacancy rates for your specific property and comparable buildings
- Management costs, insurance premiums, and maintenance records
- Market rent surveys from local property management companies
The assessor used specific data to reach your assessed value. Your protest needs to show why that data was incorrect or incomplete. NC small multifamily cash flow analysis techniques apply similarly in SC for documenting actual property performance.
County Filing Process: Forms, Fees, and Initial Review
Each SC county handles protests slightly differently, but all require written submissions within the 90-day deadline. Some counties provide specific forms, while others accept detailed letters that include required information.
Standard Filing Requirements:
- Property owner name and mailing address
- Property address and tax map number
- Current assessed value being protested
- Requested assessed value with supporting reasoning
- Owner signature and date
Most counties charge no fee for the initial protest filing. However, if your case advances to the county board of appeals, some counties impose fees ranging from $25 to $100.
After filing, expect an informal review period where the county assessor's office examines your evidence. This review typically takes 30 to 60 days. The assessor may schedule a property inspection or request additional documentation during this phase.
If the informal review doesn't resolve your protest, the case advances to a formal county board hearing. This board consists of local citizens appointed to review assessment disputes.
Common Protest Grounds for Small Multifamily Properties
SC law allows protests based on incorrect market value, wrong assessment ratio, or improper classification. For small multifamily owners, market value disputes represent the most common and successful protest ground.
Overvaluation Issues:
- Assessor used inflated comparable sales from different market areas
- Assessment ignored significant deferred maintenance or needed repairs
- Income projections assumed unrealistic rent levels or occupancy rates
- Property characteristics were recorded incorrectly in county records
Assessment Ratio Problems:
- Property classified incorrectly as commercial instead of residential
- Assessment ratio applied incorrectly based on property use classification
- Special use valuations not properly applied where eligible
Small multifamily properties often get caught between residential and commercial classification systems. A triplex might be assessed using commercial rates when residential rates should apply, significantly increasing the tax burden.
When to sell vs refinance small multifamily in NC considerations include ongoing property tax increases that affect long-term returns, a factor equally relevant for SC owners.
After Filing: Board Appeals and Administrative Law Court Options
If the county assessor doesn't adjust your assessment after the informal review, your case proceeds to the county board of appeals. This formal hearing typically occurs 60 to 90 days after your initial protest filing.
County Board Process:
- Written notice of hearing date and time
- Opportunity to present evidence and testimony
- Right to bring witnesses or professional appraisers
- Board decision issued within 30 days of hearing
The county board can uphold, reduce, or increase your assessed value based on evidence presented. If you disagree with the board's decision, you have 30 days to appeal to the SC Administrative Law Court.
Administrative Law Court appeals require more formal legal procedures and often benefit from professional representation. These appeals focus on whether the county board followed proper procedures and made decisions supported by evidence.
Timeline Summary:
- Day 1-90: File written protest with county assessor
- Day 91-150: Informal review and possible property inspection
- Day 151-240: County board hearing if informal review fails
- Day 241-270: Appeal to Administrative Law Court if needed
Many owners find the county board level resolves their disputes without needing court appeals. However, understanding the full process helps you evaluate whether continuing an appeal makes financial sense.
Strategic Considerations for SC Multifamily Owners
Property tax protests require significant time investment and don't guarantee success. Before filing, calculate whether potential tax savings justify the effort involved in preparing and presenting your case.
For properties you're considering selling, factor ongoing assessment battles into your exit timing decisions. 7 exit timing indicators every NC small multifamily owner should track include property tax trends that equally apply to SC markets.
Some owners protest annually as assessments climb, while others focus energy on optimizing property performance or planning strategic exits. The protest process can take six months to complete, during which property tax bills continue arriving and market conditions may shift.
When Protests Make Sense:
- Assessment increased more than 20% without corresponding property improvements
- Clear evidence exists that comparable sales don't support the assessed value
- Property classification errors create substantial tax overpayments
- You plan to hold the property long-term and want to establish assessment precedent
