Dear Sir,
what i understood from the facts narrated by you is that you have paid services tax (suppose value of services provided by you was ₹ 100) on ₹ 100 @ of 12.36%. later on because of some reasons service recipient decided to not you pay you full ₹ 100 along with service tax @ 12.36%. So after settlement he decided you pay you 50% of the value of service provided by you plus service tax on the rate of 14.5%. to me is appears a case of renegotiating of value of service covered under Rule 6(3) of the ST Rules, 1994. as per Rule 6(3) you can take the credit of tax paid in excess by you. Let me explain this in detail.
Suppose your provided services of worth ₹ 100 and add service tax of ₹ 12.36 % and thus raise an invoice of total 112.36. you recipient found some deficiency in serivce of for some breach of terms of contract and thus decided not you pay you full value of service. after settlement you and your service receiver reach on consensus that service receiver will pay 50% of the value of service because as per his understanding service provided by you worth only 50% of the value as determined by you. in other words he will pay you Rs. plus 12.36% of ₹ 50. it becomes around 56.18. now you have already paid tax of ₹ 12.36 where as you have inactual provided services of worth 50 only and hence tax payable is rs. 6.18 only. what will happen you rs. 6.18 which you have already paid in excess. this 6.18 Rs. which you have already paid in excess, as per Rule 6(3) assessee can take the credit of such excess service tax paid.
i suppose in your case, service provider has wrongly paid you tax at the rate f 14.5% as service tax would have been paid at the rate of 12.36% only. The rate applicable will be the one prevailing at the time of provision of service and not the rate prevailing at the time of payment.
Rule 6(3) and 6(4A) are distinct. Rule 4A allows for adjustment of service tax paid in excess towards succedding month or quarter tax liability however such adjustment is possible only in a situation where excess service tax was paid not because of reasons mentioned under Rue 6(4B).
Rule 6(3) talks about taking credit of the excess service tax paid. it operate in a situation where service has not been provided fully or partially or value of service has been renegotiated.
kindly choose the option available under Rule 6(3) or Ruel 6(4A) read with Rule 4(B) depending on your case. my feeling is that your case is of the nature falling under Rule 6(3). here i am just relying on my experience while dealing with companies.
