Tax relief and valuation review

Protect your exemption and appeal rights.

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 Williamsburg County Assessor's Office.

What the local record says

Homestead filing

The filing guidance for this county is: For the 2026 tax bill, new homestead applicants should apply April 1–August 15, 2026; the post-application period runs July 16, 2026 through the first penalty date, January 15, 2027. The separate 4% legal-residence application should be filed with the Assessor before the first penalty date. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.

Open homestead application

Senior citizen tax relief

South Carolina Homestead Exemption: a qualifying homeowner who was at least 65 by December 31, 2025, totally and permanently disabled, legally blind, or a qualifying surviving spouse may receive the first $50,000 of fair-market value of the legal residence exempt from county/municipal taxes, with school operating taxes also exempt under the state school-tax credit; apply through the county Auditor.

Valuation cap or growth limit

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; legal residences generally use the 4% assessment ratio and other real property generally uses 6%.

Appealing an assessment

Build the objection around evidence and the notice date.

Calendar the window

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.

Assemble support

Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.

File and preserve proof

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: Written appeal within 90 days after the date on the 2026 Notice of Classification, Appraisal & Assessment; if no notice is issued, a written appeal filed before January 15, 2027 applies to the 2026 tax year, under South Carolina Code §12-60-2510. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
