Buying a second home on Hilton Head Island should feel exciting, not confusing. Yet the way South Carolina taxes second homes can change your annual costs more than you might expect. If you understand how assessment ratios, millage, insurance, and rental taxes work here, you can plan with confidence and avoid surprises at closing. This guide breaks down the essentials and gives you a clear checklist to use on any property you’re considering. Let’s dive in.
Primary vs second‑home taxes in South Carolina
South Carolina classifies homes as owner‑occupied primary residences or non‑owner‑occupied properties. Second homes and most rentals fall into the non‑owner‑occupied category. That classification determines the assessment ratio used to convert market value into the assessed value that gets taxed.
To claim owner‑occupied status, you typically file documentation with the county and meet standards such as where you vote or file state taxes. If your use changes, you need to notify the county. For current definitions, forms, and any updates to ratios, review the South Carolina Department of Revenue’s property tax resources and your local county guidance. You can start with the South Carolina Department of Revenue property tax resources and the Beaufort County Assessor and Treasurer.
How millage works on Hilton Head
Millage is how local governments apply tax rates to your assessed value. One mill equals one dollar of tax for every 1,000 dollars of assessed value. The core formula is simple: Assessed Value equals Fair Market Value multiplied by the Assessment Ratio, then Property Tax equals Assessed Value multiplied by Total Millage divided by 1,000.
Your total millage is a sum of several parts. It can include county mills, municipal mills if the property is inside the Town of Hilton Head Island, school district mills, and special district mills such as fire or library districts. Because each parcel’s mix can be different, confirm the total for any specific address with the Beaufort County Assessor and Treasurer and the Town of Hilton Head Island.
Quick example to visualize the math
Here is a hypothetical illustration, not a quote. Assume market value is 600,000 dollars, the owner‑occupied assessment ratio would make the assessed value 24,000 dollars if the ratio were 4 percent, and the combined millage were 220 mills. The annual property tax would be 24,000 multiplied by 220 divided by 1,000, which equals 5,280 dollars.
If the property is classified as non‑owner‑occupied, the assessment ratio is different. That changes the assessed value and the final tax bill. Always confirm current ratios and the exact millage for the parcel with county and state sources before you budget.
Closing costs to expect on Hilton Head
Beyond your down payment, plan for standard buyer closing costs. These can include lender fees, appraisal, survey if required, home inspection, title search, title insurance, recording and deed prep, and prepaid items for insurance and interest. You will also see prorations for property taxes and HOA or condo dues.
Hilton Head’s resort communities commonly add HOA transfer or processing fees and sometimes capital contributions. If you plan to rent, you may need local registration or business licensing. Coastal homes often require wind and flood insurance evidence prior to closing, and lenders may set escrow accounts to cover future premiums. Ask your lender for a Loan Estimate and review the Closing Disclosure carefully to see how these items are handled.
Ongoing costs for second‑home owners
Property taxes renew each year based on assessed value and millage. If your use changes or you receive a revaluation, your bill may change. Keep copies of tax bills and track any notices from the county.
Insurance is another core cost. Coastal properties face wind, hail, and hurricane risks, which can raise premiums and deductibles. Flood insurance may be required by lenders and is common on barrier islands. Check your address in the FEMA Flood Map Service Center, and use FloodSmart to learn how elevation, prior claims, and construction details affect premiums.
HOA or condo dues cover common‑area maintenance, landscaping, security, and amenities, and some associations levy special assessments. Budget for utilities such as electricity, water and sewer, internet, and trash. Coastal maintenance can run higher due to salt air and humidity, so it helps to set aside reserves for exterior upkeep and major systems.
Planning to rent your property
If you intend to short‑term rent, add a few more items to your plan. Professional vacation management often charges a fee that can range widely by service level. You will also have guest‑turnover expenses such as cleaning and restocking.
Most jurisdictions require operators to collect and remit accommodations taxes and to hold appropriate licenses. On Hilton Head, confirm business licensing and any rental rules with the Town of Hilton Head Island. For statewide rules on accommodations and sales tax, review state accommodations and sales tax guidance. Because federal and state income tax treatment depends on your personal use and expense tracking, consult a licensed CPA for advice.
How to estimate taxes on a specific address
