Singapore is one of the world’s busiest ports and a leading International Maritime Centre. Tax policy is a big part of why. The Maritime Sector Incentive (MSI), administered by the Maritime and Port Authority of Singapore, is the umbrella scheme that gathers the country’s shipping and maritime tax concessions into one framework. Whether you own ships, operate them, lease vessels and containers, or provide shipping-related services, there is likely an MSI award designed for you.
This guide explains what the MSI is, the main award types and who they suit, the tax benefits, the withholding tax exemptions on financing, and how the scheme connects to Singapore’s tonnage tax rules. It is general information and not tax advice, so seek professional guidance before applying.
What Is the Maritime Sector Incentive?
The MSI is a suite of tax incentives that supports firms across the maritime value chain: international shipping operators, ship and container lessors, and providers of shipping-related support services. It is administered by the Maritime and Port Authority of Singapore (MPA), with the tax treatment grounded in the Income Tax Act 1947 on Singapore Statutes Online. Rather than a single benefit, the MSI is best understood as a family of awards, each targeting a different maritime activity.
The Main MSI Awards
There are four principal awards under the MSI umbrella. Choosing the right one depends on what your company actually does.
MSI-AIS (Approved International Shipping Enterprise)
The MSI-AIS award encourages established international shipowners and operators to base their commercial shipping operations in Singapore. An approved company enjoys tax exemption, or an alternative basis of tax calculated on the net tonnage of its ships, on qualifying shipping income. The award is granted for a five-year non-renewable period, with the option to graduate to a ten-year renewable award if the qualifying conditions are met.
MSI-SRS (Shipping Enterprise, Singapore Registry of Ships)
The MSI-SRS award supports companies that own or operate ships registered under the Singapore Registry of Ships, and qualifying foreign-flagged vessels. Qualifying income from operating these ships is exempt from tax, and withholding tax exemptions are available on qualifying financing. This award ties closely to the tonnage tax framework, which we cover in our guide to Section 13A and 13E tonnage tax.
MSI-ML (Maritime Leasing)
The MSI-ML award enhances Singapore’s position as a funding base for maritime assets. It offers tax concessions for up to five years on qualifying leasing income earned by ship or container leasing companies, business trusts, and partnerships. It suits lessors and financiers who put vessels and sea containers on the water rather than operate them.
MSI-SSS (Shipping-Related Support Services)
The MSI-SSS award nurtures the ecosystem around shipping. It grants a concessionary tax rate of 10% on incremental income from a range of qualifying shipping-related support services, such as ship broking, forward freight agreement trading, ship management, and maritime insurance.
MSI Awards Compared
| Award | Who it suits | Benefit |
|---|---|---|
| MSI-AIS | International shipowners and operators | Tax exemption or net-tonnage basis on qualifying shipping income |
| MSI-SRS | Owners and operators of Singapore-flagged and qualifying ships | Tax exemption on qualifying shipping income |
| MSI-ML | Ship and container lessors, trusts and partnerships | Concession on qualifying leasing income (up to 5 years) |
| MSI-SSS | Providers of shipping-related support services | 10% concessionary rate on incremental qualifying income |
Withholding Tax Exemptions on Financing
Ships and containers are capital-intensive, and much of the sector is funded by cross-border borrowing. To keep that financing efficient, the MSI framework provides withholding tax exemptions on qualifying interest and financing payments made to non-resident lenders for the purchase or construction of qualifying vessels and containers. This removes a cost that would otherwise apply to interest paid abroad, and it is a key reason ship finance is structured through Singapore.
Conditions and Substance
MSI awards are approved by MPA and are conditional on the company committing real economic substance to Singapore: local business spending, qualifying headcount, and genuine commercial operations. As with the country’s other headline incentives, the specific commitments are negotiated with the agency and set out in the award letter, and the concession is contingent on the company continuing to meet them.
How the MSI Fits with Other Incentives
Maritime groups in Singapore rarely stop at the MSI. Commodity and bunker trading operations may qualify for the Global Trader Programme, regional management functions can be supported under Regional HQ and IHQ incentives, and group treasury can sit within the Finance and Treasury Centre incentive. Our Singapore corporate tax guide sets out the headline rules these concessions improve upon.
