You cannot work or make money in Indonesia without a work permit. Working KITAS is a Visa that allows you as a foreigner to stay and work in Indonesia for a longer period of time.

It is the most comprehensive working permit you can get and allows the user to actively earn income, open bank accounts, pay taxes, get a mobile phone etc.

To obtain a working permit you need to work for a company that is registered within Indonesia. This entity can be either a Foreign Owned Company (PMA), a Representative Office or an Indonesian Owned Company.
