COLUMBIA (WACH) -- Some taxpayers have recently received letters in the mail instead of their tax return.
It's all part of the security program the Department of Revenue put into place in February to help prevent fraud related income tax filings.
The letter directs people to go to go to their website and take a Identity Verification Quiz, where they will be asked a few questions.
The department is taking extra precautions after last years computer hacking.
In October. Governor Nikki Haley announced an international hacker breached the personal information of millions of South Carolina taxpayers.
The stolen data includes bank account numbers, and social security numbers.
According to the department, only 5 percent of the 2 million who filed their taxes will receive the letter.
Anyone with any questions can contact their call center at 803-898-5000.
