NCP Days in PF Challan - employee present for 1 day

Suppose if a employee having basic of 5,00,000/= and he is present for 1 day, so his/her payable basic is more than 15000.
Now PF is 1800 that is fine but having a confusion about NCP days.
Should i take NCP days 1 or 30/31. As we deducting PF in ceiling of 15000.
please help and Thanks in Advance.

Dear Tarun,NCP days is not mentioned in PF Challan.NCP days has to be mentioned in ECR against respective member Name.The number of days for which member was not paid Salary to be mentioned in NCP Column
NCP means-Non Contributory Pay Days/Loss of Pay Days

Dear Srinath, i agree with you completely. my problem is should i mentioned 29 days in ECR file or 0, because it will impact the retirement benefits of employee.

Dear Mr Tarun, i regret that you have not understood my reply in proper perspective.The way you have framed question?
Suppose if a employee having basic of 5,00,000/= and he is present for 1 day, so his/her payable basic is more than 15000.-NCP to be mentioned 1 day-Total days in the Month
Now PF is 1800 that is fine but having a confusion about NCP days.
Maximum Contribution for EPS Presently Rs15,000/-Per Month.As per your example, it will have no impact on Pension
is it a hypothetical question? Please revert, if you still have any query
NCP days is required for EPF also to determine length of Membership

Sir,
If one person works for 5 days in a particular month then what is the NCP days we have to put in our ECR. Suppose the month is 30 days then our NCP calculation is 30days - 5 working days = 25 days or 26 days - 5 working days = 21 days. Please explain.

Dear Friend, NCP Means Non Contributory Pay details to be mentioned in terms of Days from the perspective of EPS Contribution.
The number of days for which an Employee has not earned Salary in a particular Month has to be entered in ECR
For how many days an Employee has worked is not the criteria.For how many days an Employee has not earned Salary, in a particular Month.
Hope this clarification will suffice

Emloyee ncp days is 15 for august. Have given gross wage of Rs 2,708/-. My question now is what will be the per day minimum wage calculation from PF department for this case?? Will it be 2708/(31-15) = 180.533 or 2708/(27-15)= 225.666 or something else???
