No. An individual and a business are two completely separate legal entities. You may be a major shareholder of the business and an employee at the same time, but you cannot mix your own account with the accounts of the MNC. You have to be very clear about the fact that once you transfer anything owned by you to the business, it will from then onwards be treated business property. Hence, separate accounts should be maintained for individuals and businesses. Its would be a prudent practice to maintain separate bank accounts also to ensure flexibility and transparency.
