If you closed on a home with us this year and it’s your primary residence, keep an eye out for a letter that just went out from our office. It’s a reminder about one of the most valuable — and most commonly missed — steps in South Carolina homeownership: applying for the 4% Legal Residence Special Assessment.

Here’s why it matters. In South Carolina, property is taxed at one of two rates: 6% for second homes, rental property, or investment property, or 4% for a home that serves as your primary, legal residence. That difference shows up directly on your tax bill every year, so it’s not a small line item to overlook. The catch is that the 4% rate isn’t automatic — even though you bought and moved into your home, the county will default you to the 6% rate unless you file an application saying otherwise.

The good news is that the process is simple, it’s a one-time filing, and once you’re approved, you don’t need to reapply each year as long as the home stays your primary residence. The application goes to your county assessor’s office (Charleston, Berkeley, or Dorchester County, depending on where you bought), and you’ll typically need to show proof that the property is truly your legal residence — things like a South Carolina driver’s license or state ID with the property address, your vehicle registration showing the same address, and confirmation that you’re not claiming a similar tax break on another home.

Timing is the part that trips people up. Counties in our area generally require the application to be filed before the first penalty date for that tax year — commonly January 15. Miss that window, and your home gets billed at the higher 6% rate for the year, with no guarantee you can go back and fix it retroactively. If you bought your home this year, that means getting your application in well before the letters and tax bills start arriving in the mail this winter is the safest move, rather than waiting until the deadline is close.

If you’re one of our buyer clients and you’re not sure whether you’ve already filed this application — maybe your lender or closing attorney handled it, maybe you haven’t gotten to it yet — it’s worth a quick call to your county assessor’s office to check your status before the deadline passes. It only takes a few minutes, and it’s the difference between paying 4% or 6% on your property for the year ahead.

We send these reminders every year because it’s an easy thing to lose track of in the middle of moving, unpacking, and settling into a new home — and because it’s real money. If you have questions about the process or aren’t sure which county office to contact, reach out to us. We’re happy to point you in the right direction.
