Aiken County Property Tax Appeal, South Carolina

Travis Bunn·Updated July 22, 2026

Aiken County is located in western South Carolina along the Georgia border, with Aiken serving as the county seat. The county has a population of approximately 181,515 (2025 estimate) and includes major cities such as Aiken and North Augusta, as well as smaller municipalities like New Ellenton, Graniteville, and Wagener. Aiken County is known for its equestrian heritage, the Savannah River Site, and its proximity to Augusta, Georgia. Property tax appeals matter significantly here because Aiken County maintains one of the lowest effective property tax rates in South Carolina at 0.48-0.49%, well below the state median of 0.66% and the national median of 1.02%. The county's median home value of approximately $181,800 results in a median annual tax bill of around $805, making it substantially lower than the national median of $2,400, which means even small assessment errors can impact homeowners despite the favorable rates.

On the typical Aiken County home, valued near $181,800 at the county’s effective tax rate of 0.48%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

2026 Appeal Deadline: 90 days from the date of assessment notice, or before January 15th in non-reassessment years

In years when you receive a reassessment notice (mailed in early July), you have 90 days from the date of the notice to file an appeal. In years when there is no notice of property tax assessment, you may appeal at any time, but appeals submitted before the first penalty date (usually January 15th) apply to the current property tax year, while appeals submitted on or after January 15th apply to the succeeding property tax year. For 2026, reassessment notices were mailed during the first week of July, giving property owners until approximately early October 2026 to file appeals.

How Aiken County Assesses Property

4%of market value

Assessed by: Aiken County Assessor's Office

Assessment cycle: quinquennial (every five years)

Notices typically mailed: Early July (first week of July)

In Aiken County, property taxes are based on assessed value, not market value. South Carolina law requires owner-occupied residential properties to be assessed at 4% of fair market value, while non-owner occupied and commercial properties are assessed at 6%. For example: if your home's market value is $181,800 (the county median), at South Carolina's 4% assessment ratio your assessed value would be $7,272. At Aiken County's effective tax rate of 0.48%, this results in approximately $805 in annual property taxes. This 4% assessment ratio is one of the lowest in the nation and provides significant tax relief for homeowners who claim their property as their legal residence.

The Appeal Process

Appeals are heard by the County Assessor. After filing your appeal, the Assessor's Office will review your evidence and may schedule an informal hearing where you can discuss your concerns with an assessor. If the matter is not resolved informally, it proceeds to a formal hearing before the Board of Assessment Appeals or Administrative Law Judge Division, where both parties present evidence and testimony.

Review your assessment notice carefully to verify the market value and assessed value of your property. Compare your assessed value to similar properties in your neighborhood using the county's online property search at qpublic.net/sc/aiken.

Gather supporting evidence including recent comparable sales of similar properties in your area, photographs documenting property condition issues, repair estimates for any defects, and your own independent appraisal if available.

Submit your written appeal to the Aiken County Assessor's Office within 90 days of your assessment notice date (or before January 15th in non-reassessment years). Your appeal must identify the property by tax map number and provide your estimate of fair market value.

The Assessor's Office will review your appeal and may schedule an informal hearing to discuss your concerns. The Assessor conducts informal hearings to resolve disputes before they proceed to formal proceedings.

If the informal review does not resolve your appeal satisfactorily, your case may proceed to the Board of Assessment Appeals or Administrative Law Judge Division for a formal hearing where you can present your evidence.

If you disagree with the decision of the Board of Assessment Appeals or Administrative Law Judge, you may appeal to the South Carolina Administrative Law Court.

As a final option, if all administrative appeals are exhausted and you still disagree with the assessment, you may appeal your Aiken County tax assessment in court.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Aiken County for 2026?

For properties that received reassessment notices in early July 2026, you have 90 days from the date printed on your assessment notice to file an appeal, which means approximately early October 2026. In years when there is no reassessment notice, you can appeal at any time, but appeals filed before January 15th apply to the current tax year, while those filed on or after January 15th apply to the following tax year. It's critical not to wait until the last minute, as failure to file within the appeal period constitutes a waiver of your right to appeal for that tax year.

How do I file a property tax appeal in Aiken County?

To file a property tax appeal in Aiken County, you must submit a written objection to the Assessor's Office at 1930 University Parkway, Suite 2400, Aiken, SC 29801. While a Property Appraisal Objection Form is available on the county website for reference, you can also submit a letter of disagreement. Your appeal must properly identify the property by tax map number, state your estimate of the property's fair market value, and include supporting documentation such as comparable sales data, photographs, or repair estimates. You can submit your appeal by mail (registered mail recommended), in person, or request a form by calling (803) 642-1583.

What is the homestead exemption worth in Aiken County?

The homestead exemption in Aiken County exempts the first $50,000 of your home's fair market value from all property taxes, including county, municipal, school, and special assessment taxes. This exemption is available to South Carolina residents who are age 65 or older, totally and permanently disabled, or legally blind. For example, if your home has a fair market value of $180,000 and you qualify for the homestead exemption, only $130,000 would be subject to the 4% assessment ratio, significantly reducing your annual property tax bill. Applications must be filed with the Aiken County Auditor's Office at (803) 642-1514, and can be submitted anytime before January 15th when taxes are due.

What happens after I file a property tax appeal in Aiken County?

After you file your property tax appeal, the Aiken County Assessor's Office will review your submission and supporting evidence. The Assessor conducts informal hearings to discuss your concerns and attempt to resolve the dispute before formal proceedings. If the informal review resolves your appeal satisfactorily, your property will be reassessed at the agreed-upon value and your taxes will be adjusted accordingly. If the matter cannot be resolved informally, your case will proceed to a formal hearing before the Board of Assessment Appeals or Administrative Law Judge Division, where both you and the Assessor present evidence and testimony. You will receive written notification of the decision at each stage of the process.

How much can I save by appealing my property taxes in Aiken County?

According to available data, successful property tax appeals in Aiken County save homeowners an average of $290 per year. However, your actual savings depend on how much your assessed value is reduced and your property's total millage rate. For example, if you successfully reduce your home's market value by $20,000, your assessed value would decrease by $800 (at the 4% assessment ratio). At Aiken County's effective rate of approximately 0.48%, this would save you roughly $384 annually. Given that approximately 25% of homes nationally are over-assessed, it's worth reviewing your assessment, especially if you've recently completed a reassessment year like 2026.

What evidence do I need for a successful Aiken County property tax appeal?

The most effective evidence for an Aiken County property tax appeal includes recent comparable sales (within the past 6-12 months) of similar properties in your neighborhood that sold for less than your assessed value. You should also provide photographs documenting any property condition issues, functional obsolescence, or deferred maintenance that affects value. Professional appraisal reports, contractor repair estimates, and documentation of property characteristics that differ from the assessor's records (such as incorrect square footage or features) are also valuable. The Assessor's Office reviews previous appraisals, expert opinions, and comparable property data, so organizing this evidence clearly with supporting calculations showing why your property is over-valued will strengthen your appeal.

When does Aiken County reassess properties and mail assessment notices?

Aiken County is required by South Carolina law to conduct a countywide reassessment every five years. The most recent reassessment was implemented for tax year 2026, with appraisers completing field reviews by December 31, 2025. Assessment notices for all Aiken County property owners were mailed during the first week of July 2026, showing both market value and assessed value following the reassessment. This notice is not a tax bill; actual tax bills are mailed separately in October. South Carolina's Act 388 limits the increase in taxable value for many property owners to 15% in a reassessment year, which can help reduce the impact of rising property values on your tax bill.

Does Aiken County offer property tax exemptions for disabled veterans?

Yes, Aiken County offers a complete property tax exemption for 100% totally and permanently disabled veterans on their primary residence and up to 5 acres of land. This exemption covers all property taxes and can be claimed retroactively to the year the disability occurred (back to 2022 under recent legislation). Veterans with disability ratings below 100% may qualify for a partial exemption equal to their disability percentage. Surviving spouses can immediately claim the exemption in the same manner as the veteran, regardless of whether the disabled veteran ever applied for it. Applications should be filed with the South Carolina Department of Revenue, and the exemption also extends to up to two private passenger vehicles owned by the disabled veteran or spouse.
