Does an unpaid income tax liability affect ex entry back into Singapore?

An unpaid income tax liability may affect your re-entry into Singapore. If you have an outstanding tax liability, the Singapore Customs and Excise Department can issue an exit permit but may withhold your passport until the debt is paid. You may also be subject to legal action, such as prosecution or garnishment of your assets, if you do not pay your taxes.

To avoid any complications, it's important to resolve any outstanding tax liabilities before attempting to re-enter Singapore. You can contact the Singapore Customs and Excise Department to discuss your situation and make arrangements to pay your debt.
