ESI Calculate on Gross Salary if your Gross Salary within
10000/ pm & PF Calculate on Basic Salary.
Exp ESI: If your Gross Salary is Rs. 7500 then ESI Deducted
1.75% on Rs. 7500 = 132/-

Exp PF:If Your Basic Salary is Rs. 5000/- then PF Deducted
12% on Rs. 5000 =600/- (Both Emplyer & Emplyee 12%
contribution as per PF Scheme 1995)

ESI amount for Employee on Gross Salary @ 1.75% on Rs.15000
W.E.F 01.05.2010 and Employer @ 4.75%.
PF 12% on Basic + DA for Employee and Employer Will also pay
12%, But Employer's contribution goes two ways .In this
employer contribution 3.67%
will goes to PF account rest of amount 8.33% will goes to
pension fund.EPS salary was maximum 6500/-.

Our Company is engaged in Construction activities. We are
going to purchase Exacavator Machine from the interstate.
Whether the above purchase covered by issuing C form ?
Whether can we apply for C Forms in sales tax Dept ?
Please clarify sir

The party has raised service bill for Rs. 120000. The TDS
deductor company made TDS on Rs. 100000 i.e., Rs.20000 is
deducted on the gross bill of Rs 120000. My question is
whether to deduct TDS on Rs.120000 or on Rs. 100000?
