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 McCormick County Assessor's Office.
Relief programs
The filing guidance for this county is: For 2026, file the legal-residence, agricultural, and applicable homestead materials with the county assessor/auditor before January 15, 2027, unless the county application or notice specifies an earlier deadline. 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: the first $50,000 of fair-market value of the legal residence is exempt for a qualifying homeowner who is at least 65 by December 31 preceding the tax year, totally and permanently disabled, legally blind, or a qualifying surviving spouse; apply through the county auditor with proof of age, residency, or disability.
South Carolina Real Property Valuation Reform Act: taxable-value growth is generally limited to 15% over five years at countywide reassessment. The cap is generally removed for an assessable transfer of interest and does not cover new construction, additions, or improvements; owner-occupied legal residences use the 4% assessment ratio and 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 the 2026 tax year, file a written assessment appeal within 90 days of the assessment notice; if no assessment notice is issued, file by January 15, 2027, the first penalty date, under the county's South Carolina appeal procedure. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
