Throughout Jakarta there are numerous foreign and local banks all offering a full range of banking services. Many offer both Rupiah and foreign currency (usually US$) savings and checking accounts, term deposits, as well as credit and debit card accounts and foreign exchange services. Safe deposit boxes are also available at some banks.
Foreign Banks generally have several requirements for opening a personal bank account including letters of reference from your employer or sponsor as well as copies of your passport and KITAS card. For checking accounts a reference from your previous bank, your company's Tax Registration Number and a letter from your company verifying that Indonesian income tax is paid by the company should also be submitted. In order to open a personal account in US$ many banks also require a minimum deposit be maintained. Because of the vast range of services and policies unique to each bank, it is advisable to call and make inquiries directly, then follow up by a personal visit.
Many expatriates living in Indonesia choose the option of maintaining their normal account in their home country or opening an account in Singapore. Their employer will then transfer their salary each month directly to this account. You may choose to receive part of your wages in Indonesia in Rupiah cash to cover your cash expenditures in Jakarta. Some companies also have a system where you can write a personal check from you home account and the company will issue you Rupiah cash.
