is reverse charge in case of services of manpower supply applicable on private limited ?

Can any explain me what is abated value and non- abated value of Service tax?

We have two manufacturing units both registered under same pan number but having different service tax registration numbers. During the payment of service tax liability, we had mistakenly paid service tax under wrong unit assessee code. Please let me know the remedies available with regards to the same.

Value of taxable service for builders
Example - Total receipt from flat owners Rs. 1650000/- so taxable value for Service tax is Rs. 412500 (1650000/-*25/100) assuming all flat less 2000 sg.ft. & below Rs.1cr.
In this case of builder can get basic exception of Rs. 10Lakh?
If so there is no service tax liabilities for during the year .?

Dear Sir,
Kindly let me know whether Service tax is payable if a flat is sold after obtaining of completion certificate from Local Authority( i.e. Corporation or Municipality). In other case if part of flat value is taken beforehand and before taking the balance amount received completion certificate is obtained .Do one has to pay the service tax or not. if he sells his flat after obtaining completion certificate but if he takes advance part of flat value before receiving completion certificate then has he to pay service tax on full amount of consideration money or on the part of Flat Value before receiving completion certificate.

I am unable to differentiate properly between the two types of services . . would humbly request the panel to guide me in drawing a line of demarcation between the two services..
