Dear RAMANIKLAL,
On the basis of my understanding your question, my reply to you is as under:
You need to follow the minimum rate of wages as declare by the State Government from time to time and as applicable to your industry and category of employees.
The rates declare by the State Governments are under the Minimum Wages Act. The rates includes Basic and DA (Special Allow.in Maharashtra). You are liable to pay the Basic and DA or Basic component inclusive of DA as per the rates as declared from time to time. These are the rates at minimum. You can not give less than it . If you pay more than it, there is no question.
As I said, this rates includes only Basic and DA. No allowance is included in it. There is no law tells you to pay any allowance except in some States there is a law to pay HRA.
PF is deducted on Basic and DA which is paid payable not less than the minimum wage rate as applicable. In your word this Basic and DA which is paid not less than the minimum wage rate is IDEAL BASIC RATE and this does not infringe any law.
I thing, you have not understood the PF law. PF law says that Contribution is to be deducted from Basic and DA subject to maximum on RS. 15000.
Example: If an employee is paid Rs.16000 per month as Basic + DA and he is a member of PF, then PF is deducted on Rs. 15000 and not on Rs. 16000.
Hope my reply satisfies your query.
