Documents for Opening a Personal Bank Account in Singapore: Identity, Address, Pass, Tax Residence and Source of Funds

The documents for opening a personal account in Singapore exist to answer five questions the bank is legally required to ask: what your name is, what your ID number is, where you live, when you were born and what your nationality is. These five items are the minimum MAS Notice 626 requires a bank to identify for an individual customer. On top of them, the bank collects a tax residency self-certification and TIN and, depending on the case, asks about source of funds and the purpose of the account. People in different situations prove this information with different documents, so the checklists below are split into three: citizens and PRs, foreigners with a pass, and non-residents.

This page lists common requirements from public sources (as at October 2026), using DBS, OCBC and UOB pages as examples; each bank's latest published list prevails. For how channels differ by status, see Three groups, three routes.

The legal minimum: what a bank must verify

Paragraph 6.6 of Notice 626 (2024 version) requires a bank to obtain at least the following five items when identifying an individual customer:

Paragraph 6.9 requires banks to verify identity "using reliable, independent source data, documents or information". This explains two common observations: banks prefer documents issued by government or regulated institutions, and handwritten address declarations or letters from friends and relatives are usually not accepted. The Notice also prohibits anonymous accounts and accounts in fictitious names (paragraph 6.1), and each holder of a joint account must go through due diligence as a separate customer (paragraph 6.37).

Checklist A: Singapore citizens and PRs

Checklist B: Foreigners holding a Singapore pass

DBS's page also sets out a rule that is easy to trip over: the IPA can be used either as proof of address or as proof of employment, but "not both". If you have already used the IPA to prove your address, you need another document, such as an employer letter, to prove your employment or study status.

Checklist C: Non-residents without a Singapore pass

DBS also requires the address to be updated through digibank once a Singapore address is obtained. For the tiers and thresholds non-residents are typically directed to, see Priority and private banking thresholds.

Tax residency self-certification and TIN

Under the Common Reporting Standard (CRS), IRAS states that an individual's self-certification must include: name, address, every jurisdiction of tax residence, the TIN for each jurisdiction of tax residence, and date of birth (IRAS, updated 19 Oct 2021). Account holders should declare truthfully and inform the bank promptly when their tax residence changes.

If you do not provide a self-certification, the financial institution may have to report the account information to IRAS and may refuse to open the account or close it; falsely declaring tax residence can attract a fine of up to S$10,000 or imprisonment of up to two years (IRAS). For the full explanation, see CRS and TINs. Applies to Singapore and mainland China; for cross-border tax questions, seek professional advice in your jurisdiction.

Source of funds and purpose of the account

Source of Funds refers to where the money being deposited this time comes from, such as salary or proceeds from selling an asset. Source of Wealth refers to how your overall assets were accumulated, such as running a business or an inheritance. For an ordinary retail account, the bank may only ask about your occupation, income range and purpose of the account; for priority or private banking, or in higher-risk situations, the bank will ask for a written explanation and supporting evidence.

At the regulatory level, paragraph 8.3 of Notice 626 requires that where a customer or beneficial owner is a politically exposed person (PEP), or a family member or close associate of one, the bank must obtain senior management approval, establish source of wealth and source of funds by appropriate and reasonable means, and apply enhanced ongoing monitoring. Paragraph 6.23 requires banks to enquire into the background and purpose of unusual transactions.

Supporting evidence you might prepare, depending on your circumstances (not all of it will be needed): an employment contract, recent payslips or tax filing records; contracts and receipt records for the sale of property or shares; company registration and dividend records for business owners; legal documents for an inheritance or gift. The basic principle is to explain truthfully, completely and verifiably, and to keep the original documents. This site does not provide any wording on "how to get through the review".

Ten checks before you submit

• [ ] 1. Your ID is valid, and the remaining passport validity meets the bank's requirement
• [ ] 2. Your pass or IPA is valid and its type matches the application form; the IPA has not been used for "both"
• [ ] 3. Your proof of address was issued within three months and is not a tenancy agreement
• [ ] 4. The name and address on the proof of address match the application form exactly
• [ ] 5. You have confirmed whether the channel accepts electronic copies or originals only
• [ ] 6. You have listed every jurisdiction of tax residence and its TIN
• [ ] 7. You have truthfully declared whether you are a US person (if applicable)
• [ ] 8. The purpose of the account and expected funds are consistent with your occupation and income
• [ ] 9. Where source of funds needs explaining, supporting evidence is complete and the amounts reconcile
• [ ] 10. Your mobile number and email are registered in your own name

Having all the documents does not guarantee that an account will be opened; whether to establish a business relationship is the bank's decision based on its customer due diligence.
