Service tax on reverse charge??

Dear Members,

In case of GTA, Service Tax payable by the recepient of Services at the time of payment made to service provider. My question is that, If service is received in march 2012 and payment made in April  2012 then Whether that amount of Invoice and Service Tax should be shown in Service Tax return for the period of Oct 2011 to march 2012. if yes then how?? becouse payment of service tax is not made in march and it is due in April 2012, so paid in april month.

Please solve the querry as soon as possible..

Thanks in Advance
