Clarification on Service Tax Deduction

Dear Sir

I am an accountant of a hotel in Cochin,

recently i took service tax registration.

about service tax in hotel industry i read as per the below notes

" in hotels where rooms having tariff of less than rs. 1000/- and another set of rooms with tariff more
than rs. 1000/-, service tax will be attached on rooms with higher tafiff only"

as per this i requested the software people to install the service tax deduction facility for rs. 1000/- above
but they said that all the bills [ie below rs 1000/-] are covering service tax deduction @ 7.42%

please advise the actual service tax deduction amount.

Thanks and Regards

Praveen
