York County’s property taxes are one of the main financial arguments for buying in Fort Mill or Tega Cay instead of a comparable neighborhood on the North Carolina side. But the actual savings depend almost entirely on one thing: whether you file for the 4% legal residence exemption. Miss that filing, and you pay roughly 50% more than you should. Here’s what you need to know before you buy and after you close.
How South Carolina Property Taxes Work
South Carolina assesses property at a percentage of fair market value, then applies a millage rate to that assessed value. The percentage — called the assessment ratio — depends on how you use the property:
- Primary residence (legal residence): 4% assessment ratio
- Non-primary / investment property: 6% assessment ratio
That 4% vs. 6% difference means a primary homeowner’s taxable base is one-third lower than an investor’s on the same property. This is the single biggest lever in your property tax bill.
The 4% Legal Residence Exemption
If you’re buying a home in Fort Mill, Tega Cay, Clover, or anywhere in York County as your primary residence, filing for the 4% legal residence exemption is the most important thing you do after closing. Here’s what you need to know:
- Who qualifies: South Carolina residents who own and occupy the home as their primary residence
- Where to file: York County Assessor’s Office (online or in person)
- When to file: Before the first tax bill on your new home — ideally within the first few months of purchase
- Documentation needed: SC driver’s license or ID, SC vehicle registration, voter registration — all showing the property address
- Frequency: One-time filing; re-application required if you move or the property changes ownership
Many buyers don’t find out about this until they get their first tax bill at the 6% rate. Filing late means you’ll pay the higher rate until the exemption is approved — which typically happens in the next reassessment cycle. Do it as soon as you move in.

Millage Rates in Fort Mill and Tega Cay
Millage rates (the rate applied to assessed value) vary by municipality and school district within York County. Fort Mill proper, unincorporated York County, and the Fort Mill school district zone each carry slightly different total millage. The York County Auditor publishes current millage rates; always confirm the specific rate for a property before purchase since it can affect your annual bill by several hundred dollars.

What York County Homeowners Actually Pay
Rather than citing specific dollar figures that can shift with reassessments, here’s the formula:
Annual tax = (Fair market value x 4%) x millage rate per $1,000
As an example, a home with a fair market value of $550,000 in the Fort Mill school district area would be assessed at $22,000 (4% of $550,000), then multiplied by the applicable millage rate. York County’s millage rates are among the lower ranges in the Charlotte metro when combined with the 4% assessment.

SC Homestead Exemption for Seniors
South Carolina residents 65 and older (or totally disabled, or legally blind) who have lived in SC for at least one full year qualify for the Homestead Exemption, which exempts the first $50,000 of fair market value from property taxes. This is in addition to the 4% legal residence rate — meaning the savings compound for eligible homeowners. [verify current homestead exemption threshold and eligibility requirements]
School District Fees
Fort Mill School District has historically maintained strong facilities and programming in part through operating levies. These are included in the millage rate calculation. When you see York County millage broken out, there will typically be county, municipal, and school district components. The school millage is a real cost — but it’s also what funds one of South Carolina’s top-rated districts, which is a primary reason families move to York County in the first place.
When Are York County Property Taxes Due?
York County property tax bills are typically mailed in October and due by January 15 of the following year. Payments made after January 15 incur penalties. Most buyers with a mortgage will have property taxes escrowed — your lender handles the payment — but if you buy cash or your lender doesn’t escrow, mark the date.

Comparing to Mecklenburg County, NC
Mecklenburg County assesses residential property at 100% of market value and applies its own millage rate. The combination of SC’s 4% assessment ratio and York County’s competitive millage rates means Fort Mill primary homeowners typically pay significantly less annually on comparable home values. The exact difference varies by price point and neighborhood, but it’s often cited as a $2,000-$4,000+ annual savings on a $500,000-$600,000 home. Full NC-to-SC tax comparison.
Frequently Asked Questions
How do I file for the 4% legal residence exemption in York County?
Contact the York County Assessor’s Office at yorkcountygov.com or visit in person. You’ll need to show SC residency documentation — driver’s license, vehicle registration, and voter registration all listing the property address. File as soon as possible after closing to avoid being taxed at the 6% investor rate.
What happens if I don’t file for the 4% exemption?
Your property will be assessed at the 6% commercial/non-resident rate, which is 50% higher than the 4% primary rate. You’ll pay roughly one-third more in property taxes until the exemption is applied. It cannot be retroactively applied to bills already paid.
Are York County property taxes going up?
York County conducts periodic reassessments that can adjust fair market values. When values increase, assessed values increase proportionally — though millage rates can be adjusted downward to partially offset the effect. Growth-driven reassessments are common in fast-growing counties. [check with York County Assessor for current reassessment cycle status]
