Is paying service tax on receipts allowed?

Till 2012, it was on cash basis,

But now every person should have to follow accrual basis only....

As per Rule 6 of service tax rules 1994, only the individuals and partnership firms whose aggregate value of taxable services provided from one or more premises is fifty lakh rupees or less in the previous year, then the service provider has the option to pay service tax on receipt basis and pay service tax quartely and file the returns half yearly. 

Thank you all. Most appreciated :)
