**Singapore’s tax advantage depends on incentives. The 15% global minimum tax mandates
a top-up for low-tax profits, affecting multinational groups with significant revenues
starting January 2025.**

### Singapore’s Value Proposition and the Global Minimum Tax

Historically, Singapore’s attractiveness to multinational companies relied on its
ability to offer low effective tax rates through incentive schemes and centralized
regional operations. However, the implementation of the 15% global minimum tax under
the GloBE framework, effective from January 2025, introduces a new dimension to 
tax assessments. This change impacts how multinationals’ tax outcomes are calculated,
emphasizing jurisdictional effective tax rates over statutory rates.

### Applicability and Calculation of the Global Minimum Tax

This global minimum tax targets multinational groups with annual consolidated revenues
of at least €750 million over two of the last four years. Exposure is determined
based on the jurisdictional effective tax rate, which uses GloBE definitions of 
income and taxes. If a Singapore operation’s effective tax rate falls below 15% 
after incentives and deductions, it becomes subject to a top-up tax, regardless 
of compliance with local tax laws.

### Impact on Multinational Operations in Singapore

When a Singapore entity’s jurisdictional effective tax rate is beneath 15%, the 
top-up tax equates to the shortfall between the actual and minimum rates. For example,
an $8 million tax on $100 million profit at 8% incurs a $7 million top-up obligation.
To address this, Singapore has introduced a Domestic Top-Up Tax (DTT) for local 
profits and a Multinational Enterprise Top-Up Tax (MTT) applying the Income Inclusion
Rule, ensuring that low-taxed foreign income is appropriately taxed within the group.
