Address How to Keep Your 4% Tax Rate When You PCS: The Military Homeowner's Guide
Location North Charleston, SC

You just got orders to move. You’re dealing with packing, the kids, and figuring out your new base. Then someone mentions that renting out your house could triple your property taxes.

In South Carolina, that’s usually true. But if you’re active-duty military, there’s a law that protects you.

The 4% vs 6% Problem

In Berkeley and Charleston County, owner-occupied homes are taxed at a 4% assessment ratio. Rental and investment properties get taxed at 6%.

That 2% gap sounds small until you see the bill. Properties assessed at 6% also pay school operating taxes that owner-occupied homes don’t. On a $400,000 home, that’s a jump from roughly $1,800/year to over $5,000/year.

If you’re PCSing and planning to rent your house out, that tax increase can wipe out most of your rental income.

SC Code 12-43-220(C): The Law That Protects You

Here’s the good news. If you receive PCS orders or a Temporary Duty Assignment (TDY) for at least one year, South Carolina law lets you keep your 4% owner-occupied rate even while renting the property out.

This applies as long as you don’t claim a primary residence tax break on another property. The law is specifically designed for military families who are forced to relocate but want to hold onto their home.

Berkeley County: What You Need to Do

Berkeley County has a strict application window. You have to apply for the 4% Special Assessment between January 2 and February 28 each year.

Here’s the process:

  1. Register an account on the Berkeley County Government Portal
  2. Gather your PCS orders
  3. Complete the 4% Legal Residence application
  4. Submit everything before the February 28 deadline

Miss that window and you’re stuck at 6% for the year. Mark your calendar.

Charleston County: What You Need to Do

Charleston County requires a similar application through the Assessor’s Office. The process is straightforward, but you’ll want to get it done early.

One additional note: if you’re a 100% Permanently and Totally (P&T) Disabled Veteran, you may qualify for a total property tax exemption on your primary home through Charleston County. That’s worth looking into separately.

Three Traps That Catch Military Homeowners

1. The double-dip. You can’t claim the 4% rate on two properties. If you buy a house at your new duty station and claim a primary residence tax break there, you lose the 4% rate in South Carolina. You have to choose one.

2. The handshake rental. If you don’t have a formal lease or property management agreement in place, the county auditor may challenge your status. Get everything documented. A professional management company creates the paper trail you need.

3. The silent spouse. If only one spouse is on the deed but the other is the service member with the orders, make sure your paperwork clearly shows the household’s military status. Clerical denials happen over this, and they’re completely avoidable.

Why This Matters for Your Bottom Line

Let’s put real numbers on it. Say you’re renting your home for $2,200/month.

  • At the 4% rate: property taxes run about $150/month
  • At the 6% rate: property taxes jump to about $420/month

That’s $270/month you’d lose just because you didn’t file the right paperwork. Over a 3-year PCS assignment, that’s $9,720 out of your pocket.

Ten minutes of paperwork. Almost ten thousand dollars saved.
