The National Tax Service has begun a tax investigation on idol singers and universities after receiving complaints that idol performance fees for university festivals have skyrocketed as of late. According to information revealed by CBS and No Cut News on April 5th, the National Tax Service began investigations on March 15th by asking universities to fill out a form detailing, from 2008 to 2010, which celebrities they had invited, how much they were paid and withholding tax, whether a contract was used, how they were invited, and other related information. One university representative claimed that they speculated tax evasion on the celebrity's end to be the cause, as festivals are usually paid for in cash without material evidence. CBS reported that in 2010, the following idol groups received an average payment of: Big Bang - $45,000 USD 2NE1/SNSD - $25,000 USD++ 2PM - $25,000 USD B2ST - $17,000 USD KARA/T-ara - $16,000 USD SECRET - $14,000 USD The numbers are alarming in that most of the payments were within the thousands, rarely ever exceeding $10,000 USD, a couple years ago. The topic of overpaying celebrities has been a hot debate for a while now, with many of the belief that the money should instead be invested in facilities for the students.� While a guideline is needed, the National Tax Service has no right to block or bring down the worth of a star in the market.
