All companies are required to pay corporate tax under the Income Tax Act, regardless of tax-residency status, on any chargeable income derived from Singapore or foreign income remitted into Singapore. However, there is neither any capital gains tax in Singapore or any withholding tax on dividends for business owners who register Pte Ltd. There are also no significant restrictions on foreign exchange transactions and capital movements, meaning funds may flow freely into and from Singapore.

        • Excluding separate source income like interest
  • Company only derives income taxable at prevailing corporate tax rate ot 17% and
  • Company not claiming the following in the YA:
        • Carry-back of current year capital allowances or losses
        • Group relief
        • Investment allowance
        • Foreign tax credit and tax deducted at source
