I was running a recruitment business for 2010-2012. For those two years i charged my clients service tax around 2.8 lakhs but not paid to service tax department, as i was not having enough capital to run the business.I closed my business in 2012 and now working a employee in a private company. I have received any email from service tax department neither any call(may be i have changed my contact number).Do I still need to pay the service tax, amount which i didnt pay that time. Can Anyone let me know how much it would be around if i am paying now.(with or without Penalty).
