The ESI return submission cycle is half-yearly, from April to September and October to March. As per your statement, you received an increment in July 2011. You are in the return submission cycle period from April to September. According to the ESI Act, if ESI is not deducted for a month in any cycle, the employer must pay ESI for the entire six months, even if the salary exceeds the limit of ₹15,000 in July of that cycle. Your ESI will not be deducted from October 2011 onwards.
Thanks,
