Banking in Singapore — the complete guide for expats

Singapore has a highly regulated, tech‑driven banking system with strong consumer protections, which makes it straightforward for expats to set up local accounts and manage money internationally. Local banks such as DBS, OCBC, and UOB, as well as international banks like HSBC and Standard Chartered, all provide English‑language services and products aimed at foreign residents.

One of the first practical steps after you arrive is to open a local bank account. While it is not a legal requirement, having a Singapore account makes daily life much smoother: most landlords prefer local transfers for rent, utilities are often direct‑debited, and many mobile plans and government services are easiest to pay using local payment methods.

The three major Singapore banks are DBS, OCBC, and UOB. All three offer strong mobile apps, widespread ATM networks, and competitive products for everyday banking. Here's how they compare for expats:

Here's a quick-reference comparison of the main options for expats. All figures are approximate and subject to change — always check with the bank directly before opening an account.

Singapore banks have relatively straightforward requirements for expats opening accounts. The exact documents vary slightly by bank, but the following will cover you at most branches:

Sending money home — or receiving salary in foreign currency — is a common need for expats in Singapore. Traditional bank wire transfers work, but they're expensive: most local banks charge S$20–30 per transfer plus an unfavourable exchange rate spread of 1–3%.

Fintech platforms have changed this dramatically. For most personal transfers, Wise and similar services offer significantly better rates with transparent fees. Here's how the main options compare:

Singapore's fintech ecosystem is one of the most advanced in Asia. Beyond traditional banks, several digital-first options are worth knowing about as an expat:

Singapore's tax system is straightforward compared to most countries, and genuinely favourable for expats. A few key things to understand:

Singapore taxes on Singapore-sourced income only. If you're earning overseas income that doesn't touch Singapore (not remitted to a Singapore bank account), it is generally not taxable here. This is a significant advantage for expats with income from multiple countries.

Tax residency matters. You're treated as a tax resident if you're in Singapore for 183 days or more in a calendar year. Tax residents pay progressive rates from 0% up to 24% — significantly lower than most Western countries. Non-residents are taxed at a flat 15% or the resident rate, whichever is higher.

Filing season runs January–April. Most expats on payroll will have tax withheld by their employer. The Inland Revenue Authority of Singapore (IRAS) makes filing relatively painless through the myTax Portal, and many expats can auto-file if their income is straightforward.

The Supplementary Retirement Scheme (SRS) is a voluntary savings scheme that offers a genuine tax benefit for expats planning to stay in Singapore for several years. Contributions to your SRS account are deducted from your taxable income for that year, reducing your tax bill immediately.

For foreigners, the annual SRS contribution cap is S$35,700 (as of 2026). If you're in a higher tax bracket — say 15% — a maximum contribution saves you approximately S$5,355 in tax in the year you contribute.

The trade-off: SRS funds are locked away until retirement age (63 for foreigners, rising to 65), at which point withdrawals are taxed at 50% of the prevailing rate. If you leave Singapore before retirement, you can withdraw early but will face a 5% penalty on top of tax.

SRS accounts can be opened at DBS, OCBC, or UOB — the same three local banks. You contribute voluntarily and can invest the funds in stocks, ETFs, and other instruments through the bank's investment platform.
