The Maritime Sector Incentive (MSI) scheme is the umbrella incentive for the maritime sector.

Incentives offered include tax exemption for shipping companies and a 10% concessionary tax rate for international freight and logistics operators. Approved ship investment managers are also taxed at 10% on qualifying management-related income. The scheme also includes approved ship investment vehicles, which are tax exempt on their qualifying vessel lease income; approved container investment enterprises, which are taxed at 5% or 10% on qualifying income from container-leasing; and approved container investment management companies, which are taxed at 10% on qualifying management fees.

From income year 2023 (year of assessment 2024), qualifying shipping entities may opt to apply an alternative net tonnage basis of tax.

Qualifying ship operators and lessors under the MSI scheme also enjoy automatic tax exemption on gains from the disposal of vessels, vessels under construction, and new building contracts.
