Dear All !

one of our client,  invoice has been issued for Whole Year that is 20-1-2011 to 19 - 1-2012, but the payment is being done through ECS every month by 20th ( for 12 months that amount would be splitting   ) and the receipt has been taken for whole year. How should Service tax and Tds should be accounted ?,
