By registered, you mean to say if its associated with R.O.C. and officially files the tax and everything?

Yes you are correct, I meant that only. You need to choose whether your company will be a partnership, corporation or an LLC. You will also need to fill out tax form, get a federal tax id number and register as a business in your area. Also have patent or copyright for innovative process.

It's overall a long process but make sure your business is registered otherwise there will be lots of problem with your work experience.

First of all,
Thanks a lot for your reply. I am so grateful to you.
If possible please guide me completely.
We are a Pvt. ltd. Company and have been filing tax since year 2009 regularly, We are listed in ROC site,
Also we have 2 Directors.

And I am getting my salary into my account every month from july 2017.
But I don't have any payslip, offer letter or anything.
What should I do.

If you are getting salary for each month from your company's official account which would have been registered along with your company then it will act as a proof for your work experience. You will need to generate bank statement from first to last month when you received your salary from official account of company.

You won't need an offer letter but as I mentioned earlier your company must have their official notepad with registered company's name and logo so you can mention your position and time period on it which is reviewed by your superior manager. If you are able to do get this then there won't be any problem.

And I will try asap to get you the whole guidelines of registering a company.

Thanks a lot,
I think you have cleared my doubts to a graet extent.
Thanks again

All the best for your exam and future process. If any more doubts you are are always welcome.

Akshay Kadam What if I have taken whole of salary at once?

Akshay Kadam What if I have been recieving whole of salary at once?
Will it be valid?

But that is already there in the experience letter

Does a work experience letter suffice alone
