How Nonhomestead Exemptions Work in South Carolina

What a Nonhomestead Exemption Is

A nonhomestead exemption is a property tax break South Carolina offers to owners of rental properties, commercial buildings, and other real estate that is not their primary residence. If you own property in South Carolina and rent it out or use it for business, you may pay property taxes at a different rate than someone who lives in their own home. The nonhomestead exemption exists because South Carolina taxes owner-occupied homes at a lower rate than investment or commercial property.

The key distinction is simple: homestead property is where you live; nonhomestead property is everything else. A homestead exemption reduces the assessed value of your primary residence for tax purposes. A nonhomestead property does not receive that reduction, so it is taxed at the full assessed value. Understanding which category your property falls into matters because it directly affects your annual tax bill.

Key Takeaways

• Nonhomestead property in South Carolina is taxed at a higher rate than owner-occupied homes because it does not receive the homestead exemption.
• You must declare your primary residence as homestead property with your county assessor to receive the lower tax rate on that home.
• Rental properties, vacation homes, commercial buildings, and vacant land are all nonhomestead property and are assessed at full value.
• The tax rate difference between homestead and nonhomestead property varies by county, so your actual bill depends on where your property sits.
• If you move or change how you use a property, you need to notify your county assessor so your tax classification stays accurate.

How Homestead and Nonhomestead Rates Differ

South Carolina law sets a lower assessment ratio for homestead property than for nonhomestead property. This means that when a county assessor calculates your property taxes, they apply different percentages to the market value depending on whether the property qualifies as homestead or nonhomestead. The exact tax rate you pay also depends on your county's millage rate—the amount per $1,000 of assessed value—which varies across South Carolina's counties.

For example, if two properties in the same county have identical market values but one is your primary residence and the other is a rental, the rental will generate a higher tax bill because it does not receive the homestead assessment reduction. This difference compounds over time, especially if you own multiple rental properties or commercial real estate. Understanding this structure helps you predict your tax obligations and budget accordingly.

What Qualifies as Nonhomestead Property

Nonhomestead property includes any real estate that is not your primary residence. This covers rental houses and apartments, vacation homes or second homes, commercial buildings, office space, industrial property, vacant land, and agricultural land used for business. If you own a property but do not live there as your main home, it is nonhomestead property for tax purposes.

A common question arises when someone owns a home but lives elsewhere: if you own a house in South Carolina but your primary residence is in another state, that South Carolina house is nonhomestead property. Similarly, if you inherit a property or own a vacation cabin, those do not receive homestead treatment. The rule is straightforward—only one property per person can be claimed as homestead, and it must be your actual primary residence.

How to Report Your Property Classification to the County

When you purchase property in South Carolina, the county assessor's office will initially classify it based on public records and deed information. If you buy a home to live in, you should contact your county assessor's office and declare it as homestead property to receive the lower tax rate. This declaration is usually made on a form called a Homestead Exemption Application or similar, and requirements vary slightly by county.

You typically need to provide proof that the property is your primary residence, such as a driver's license showing your address, utility bills, or a lease or deed in your name. Once approved, the homestead exemption applies to your tax bill. If you later move or change how you use the property, you must notify the assessor so your classification can be updated. Failing to report changes can result in paying the wrong tax rate or losing an exemption you are may have access to to.

Tax Implications for Rental Property Owners

If you own rental property in South Carolina, that property will be assessed as nonhomestead and taxed at the higher rate. This is one of several costs to factor into rental income calculations. Property taxes on nonhomestead real estate are typically deductible on your federal income tax return if you are using the property to generate rental income, so keeping records of your annual tax bills is important for tax preparation.

Rental property owners should also be aware that some counties offer agricultural exemptions or other special classifications for certain types of property. If you own farmland or timberland, you may be able to claim a different exemption that lowers your tax burden. These vary by county and have specific requirements, so it is worth asking your assessor whether your property might may have access to for any exemption beyond the standard nonhomestead classification.

What Happens When You Change Your Property's Use

Life circumstances change. You might buy a rental property and later decide to move into it, or you might live in a home and then relocate for work. When your property's use changes, its tax classification should change too. If you move into a nonhomestead property and want to claim it as your new homestead, you need to file a new homestead exemption application with your county assessor.

Conversely, if you move out of your primary residence and it becomes a rental or investment property, you must notify the assessor so it is reclassified as nonhomestead. The timing of these changes matters because tax bills are usually calculated based on the classification as of a specific date each year. Reporting changes promptly ensures your tax bill reflects your actual property use and prevents overpaying or underpaying taxes in future years.

County-to-County Differences in Nonhomestead Taxation

South Carolina has 46 counties, and each sets its own millage rate for property taxes. This means the actual dollar amount you pay on nonhomestead property depends not just on the property's value but also on which county it is located in. A nonhomestead property in one county might generate a significantly different tax bill than an identical property in another county.

If you own property in multiple counties or are considering purchasing nonhomestead property, contact each county assessor's office to understand the local tax rate. Most county assessor websites publish their current millage rates, and staff can answer questions about how nonhomestead property is taxed in their jurisdiction. This information is essential for budgeting and for comparing the true cost of owning property in different parts of South Carolina.

Frequently Asked Questions

Can I claim homestead exemption on more than one property?

No. South Carolina law allows only one homestead exemption per person, and it must be on your primary residence. If you own multiple properties, only the one where you actually live can be classified as homestead; the others are nonhomestead.

Do I have to pay property taxes on nonhomestead land I own but do not use?

Yes. Vacant land and unused property are still assessed and taxed as nonhomestead property. Owning the land means you owe taxes on it regardless of whether it generates income or is actively used.

What if I rent out part of my primary residence?

If you live in the home and rent out only part of it—such as a room or an accessory dwelling unit—the property may still may have access to for homestead exemption. However, this can be complicated, and your county assessor should review your specific situation to determine the correct classification.

How often do I need to renew my homestead exemption?

Homestead exemptions do not expire and do not require annual renewal in most South Carolina counties. However, if you move or change your property's use, you must report that change to keep your classification accurate.

Can I appeal my property's nonhomestead classification?

Yes. If you believe your property has been misclassified, you can file an appeal with your county assessor's office. The process and timeline vary by county, so contact your local assessor for instructions on how to challenge the classification.
