Greer SC Property Tax Rate: Millage, Act 388, and Exemptions

The property tax rate in Greer, SC depends on which county your home sits in, because the city straddles the Greenville–Spartanburg line. For the 2025 tax year, the total millage runs about 361 mills on the Greenville County side and about 431 mills on the Spartanburg County side.¹² Both sides share the same City of Greer municipal levy of roughly 111 mills; the gap comes from higher county operations and school district rates in Spartanburg. On a $300,000 owner-occupied home, that roughly 70-mill difference can add hundreds of dollars a year for Spartanburg-side residents.

How the Rate Turns Into a Bill

South Carolina doesn’t apply the millage rate directly to your home’s market value. The county assessor sets a fair market value, then state law multiplies it by an assessment ratio before any millage touches it. A home you occupy as your primary residence is assessed at 4%. Rental properties, second homes, and commercial buildings are assessed at 6%.³

The gap is large. A $300,000 primary residence has an assessed value of $12,000. The same home rented out jumps to $18,000. Because the millage rate applies to that assessed value, the rental owner pays 50% more tax on an identical house before anything else is factored in.

One mill equals $1 of tax per $1,000 of assessed value. So $12,000 in assessed value at 361 mills works out to roughly $4,333 before any exemption is applied. That number drops substantially once Act 388 and Legal Residence enter the picture.

What Makes Up the Greenville County Side Rate

In the Greenville County portion of Greer, the 2025 total for tax districts serving the city comes to approximately 361.1 mills. That total breaks down to about 60.1 mills for county operations, 189.7 mills for school funding, 111.0 mills for the city (including fire services), and a small fraction for other special districts.¹

What Makes Up the Spartanburg County Side Rate

On the Spartanburg side, the total reaches approximately 430.8 mills. County operations account for about 85.6 mills, Spartanburg School District 5 levies roughly 233.7 mills across several line items (current operations, bonds, and vocational education), and the city’s municipal rate holds steady at 111.0 mills.²

Two neighbors on opposite sides of the county line, with identical homes at identical market values, will see noticeably different tax bills. If you’re shopping for a home in Greer, the address matters.

Act 388 Cuts the School Operating Portion for Homeowners

South Carolina’s Act 388 removed the school operating portion of property taxes from owner-occupied homes statewide. If you live in your home as your primary residence, you don’t pay the piece of school millage that funds day-to-day operations. You do still pay the school debt service millage covering bond payments and capital projects.⁴

This is why the headline millage totals above overstate what an owner-occupant actually pays. County millage sheets print the full rate including school operating levies, so the amount billed to a homeowner with Legal Residence status will be lower than a straight millage calculation suggests. Investors and landlords get hit both ways: full school millage on top of the 6% assessment ratio.

Exemptions That Lower the Rate You Actually Pay

Legal Residence

Claiming Legal Residence status is the single most important step for any Greer homeowner. It drops your assessment ratio from 6% to 4% and triggers the Act 388 school operating exemption. The property has to be your permanent home where you intend to remain indefinitely; vacation homes and rentals do not qualify.⁵ You must have owned and occupied the residence during the applicable tax year and filed an application with your county auditor. Skip the filing and you pay the 6% rate by default.

Homestead Exemption

If you are 65 or older, totally and permanently disabled, or legally blind, you can exempt the first $50,000 of your home’s fair market value from all county, municipal, school, and special assessment property taxes.⁶ You must have been a South Carolina resident for at least one year and hold fee simple title or a life estate. At the 4% rate, this exemption removes $2,000 from assessed value, worth several hundred dollars a year depending on your millage.⁷

Disabled Veteran Exemption

Veterans with a total, permanent, service-connected disability can exempt their home, up to five acres of contiguous land, and up to two private passenger vehicles from property taxes entirely. The exemption begins in the year the disability occurs. Surviving spouses can claim the same exemption immediately, whether or not the veteran had applied for it.⁸ Qualifying veterans can also apply retroactively for the previous two tax years if they paid their property taxes on time during that window.

Reassessment and the 15% Cap on Value Increases

South Carolina law requires every county to reassess all real property on a five-year cycle.⁴ In a reassessment year the county updates fair market values, and if your neighborhood has appreciated quickly, both your assessed value and your bill can jump.

State law caps that jump. Fair market value cannot increase by more than 15% over a five-year reassessment cycle, calculated on land and improvements together.⁹ Two exceptions matter. The cap does not cover the value of new additions or improvements in the year they first become taxable, and it does not apply when the property changes hands. When a home sells, the county resets value to the sale price, and the 15% cap restarts for the new owner. New buyers in hot Greer neighborhoods sometimes see much higher bills than the prior owner paid.

Appealing If Your Value Looks Wrong

If you think the county overvalued your home, you have 90 days from the date the assessor mails your reassessment notice to file a written objection. The objection can challenge the fair market value, any special use value, the assessment ratio, or the overall property tax assessment.¹⁰

In years without a reassessment notice, you can still appeal. File the written appeal with the assessor before the first penalty date on your current tax bill, and it applies to that tax year. File after that date and it rolls to the following year.¹⁰ Comparable recent sales, a private appraisal, or evidence of property condition issues the assessor missed all strengthen the case. Appeals succeed more often than people assume, particularly after reassessment years where values push toward the 15% cap.

Payment Deadlines and Penalties

Property taxes are due by January 15, or 30 days after tax notices are mailed, whichever is later. The penalties stack quickly after that:¹¹

After January 15: 3% penalty on the unpaid amount
After February 1: an additional 7% penalty, for 10% total
After March 16: an additional 5% penalty, for 15% total, and the county treasurer issues a tax execution for collection

On a $3,000 bill, waiting until mid-March costs $450 in penalties alone. If you recently purchased the property and the tax notice went to the prior owner, the treasurer must waive penalties as long as county records show you received no timely notice.¹¹ The U.S. postmark controls for mailed payments, so a check mailed January 14 counts even if it lands January 20.
