Residential developers and Home Builders who own 10 or more undeveloped lots, who have not signed up for the multi-lot discount, or who have not re-certified their lots for the new year, need to act quickly to be eligible for property tax abatement in the 2011 tax year. Failure to apply or re-apply by May 1 will preclude your participation in the 2011 tax year and result in a significant increase in your property tax bill for the year. To apply or re-apply, contact the Greenville County Tax Assessor’s Office.
