Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with Dorchester County Assessor's Office.
Relief programs
The filing guidance for this county is: Apply for 4% legal residence and homestead relief through the county offices before the first penalty date, January 15, 2027, for 2026 taxes; active-duty military applicants reapply annually. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationSouth Carolina Homestead Exemption: up to $50,000 of fair-market value of the legal residence for a qualifying homeowner age 65 or older, totally and permanently disabled, legally blind, or qualifying surviving spouse; apply through the county auditor or county real-property services office with proof of age/residency or disability.
South Carolina's Real Property Valuation Reform Act generally limits taxable-value growth to 15% over five years at reassessment; the cap is removed for an assessable transfer of interest and generally does not cover new construction, additions, or improvements. Owner-occupied legal residences use the 4% assessment ratio; other real property generally uses 6%.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: For 2026, file a written appeal before the first January 2027 penalty date or within 90 days after the dated assessment notice, as applicable; the notice controls. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
