Sir,
As per the answer provided to Question No. 15 of FAQ dated 16.11.2015 issued by CBEC ,-
in cases where payment has been received and invoice is raised before the service becomes taxable, i.e. prior to 15th November, 2015, there is no liability of Swachh Bharat Cess.
In cases where payment has been received before the service became taxable and invoice is raised within 14 days, i.e. up to 29th November, 2015, even then the service tax liability does not arise.
Swachh Bharat Cess will be payable on services which are provided on or after 15th Nov, 2015, invoice in respect of which is issued on or after that date and payment is also received on or after that date.
Swachh Bharat Cess will also be payable where service is provided on or after 15th Nov, 2015 but payment is received prior to that date and invoice in respect of such service is not issued by 29th Nov, 2015.
In your case the service was provided prior to 15.11.2015. If you have issued the invoice on or before 29.11.2015 no SBC is payable.
