Dear Sir,
 
My query related to problem on service tax payment on Renting of immovable property.
 
Since my company leased the property to another compnay  and total rent from the property which let out is rs 12 lacs out of which we had received 9 lacs amount on monthly basis 1 lac per month but for current Last three months  i.e. Jan, Feb, March of 2014 we had not received any payment till now.
 
My question is that Service Tax on rent for last three months i.e. Jan, Feb, March of 2014 should we paid before 31.03.2014 or to be paid in the month when i receive the rent.
 
I would be kind for your valuable suggestion.
