The salary account will be converted into Regular Salary Account under the following scenarios:
If your management informs the bank that you are not working in that organisation.
If your salary is not getting credited into the account for a period of 6 months or more.
In both the above cases, the bank will have an authorization to change your salary account into Regular Salary account where you have to maintain a monthly average balance of Rs.10,000 per month or as applicable from time to time.
