In simple terms, the property’s taxable value is multiplied by the applicable assessment ratio to determine assessed value, and the assessed value is then multiplied by the local millage rate to determine the tax amount. A mill is one dollar per one thousand dollars of assessed value.

For residential property, a qualifying owner-occupied primary residence is generally assessed at 4%, while a second home, vacation home, or other non-owner-occupied residential property is generally assessed at 6%. That is why two similar properties can have very different tax bills depending on how they are classified.

No. The 4% figure is not the final tax rate. It is the assessment ratio used to calculate assessed value. The actual bill depends on the property’s value and the millage rate applied by the local taxing authorities.

In South Carolina, legal residence refers to the special 4% assessment ratio for your current primary home. It is not automatic. The owner must apply through the county assessor, and once approved, the property may also qualify for additional owner-occupied tax benefits.

Yes. In general, second homes and vacation homes are assessed at 6%, while a qualifying primary residence is assessed at 4%. South Carolina also provides certain owner-occupied benefits that are not available for a person’s second home or vacation home.

They may. South Carolina’s Homestead Exemption applies to the first $50,000 of fair market value of a qualifying legal residence for homeowners who are 65 or older, totally and permanently disabled, or legally blind.

Yes. The 4% legal residence treatment must be applied for through the county assessor. It does not apply automatically just because you own the home.

Yes, potentially. If the property later becomes your true primary residence and you otherwise qualify, you may be able to apply for legal residence treatment at that point. Timing and occupancy details matter, so this should be verified as part of your transition plan.

It can. Financing, estate planning, liability planning, and tax treatment may all be affected by how title is held. In limited situations, South Carolina rules allow certain trust-held properties and some single-member LLC situations to still qualify for the 4% assessment ratio, but that is highly fact-specific and should be reviewed before closing.

That depends on your goals. Some buyers prioritize simplicity and financing ease, while others are thinking about long-term estate planning, liability separation, or how the property may be used over time. This is usually a decision worth discussing with your lender, attorney, and tax professional before you write an offer.
