Taxes for expats in Singapore

In Singapore, income tax is paid in the year after the income accrued. (Thus it is wise to put aside sufficient funds for this when the income is paid to you.) The due amount is calculated by the tax authority ("IRAS") based on your (compulsory) yearly tax declaration.

Tax rates are low (compared to other developed countries), rules are clear and easy to understand, preparing the tax declaration (and entering it into an online system) is simple and quick.

Singapore taxes are pretty straightforward. You only pay on income earned here, no tax on foreign income, no capital gains, no inheritance tax. Stay 183+ days and you’re taxed as a resident on a sliding scale, otherwise it’s a flat rate. GST is 9%. Honestly, way simpler than most countries.

Singapore taxes only income earned locally, ... - @ahmadfarhan

This is not exactly true: Singapore taxes only income for work performed in Singapore - that is taxable in Singapore, no matter where and how it is paid. But if you, as I did in the past, work on an assignment abroad (longer than just a business trip) and still get paid in Singapore, this income in non-Taxable here (but might be taxable in the other country).
