The G7 nations have reached a landmark agreement to establish a global minimum corporate tax rate of 15%, targeting the largest and most profitable multinational companies (MNCs) like Amazon, Google, and Facebook. The goal is to discourage profit and tax revenue shifts to lower-tax jurisdictions, regardless of where sales occur.
Income from intangible assets, such as drug patents, software, and intellectual property royalties, has increasingly moved to low-tax offshore jurisdictions, allowing companies to avoid higher taxes in their home countries.
How would a global tax rate work?
The global minimum tax rate applies to overseas profits. Governments can set local corporate tax rates, but if a company pays less than the minimum in another country, the home government can impose the difference, eliminating profit-shifting advantages.
In May, governments agreed on the basic design of a minimum corporate tax. The G7 accord, adopted by the OECD and G20, supports a 15% or higher rate. Debates continue over including investment funds and real estate investment trusts.
What it means for Singapore
The global tax rules introduce uncertainty, potentially delaying investment decisions. Responses vary among MNCs, as investments differ. Tech companies may relocate more easily than manufacturers, though this depends on skilled workforce availability. Companies diversifying supply chains or needing market proximity may be less likely to move.
The new rules could reduce Singapore’s tax advantages for MNCs. Singapore’s headline corporate tax rate is 17%, but with incentives, exemptions, and rebates, effective rates range from 4.25% to 17%. Beyond taxes, MNCs value Singapore’s infrastructure, rule of law, political stability, integrity, and regional/global connectivity.
Singapore remains a key regional hub due to its skilled talent, strong intellectual property protection, and global financial hub status. To stay competitive, Singapore may need to enhance support for innovation, training, and value-added activities. The tax reforms will not apply to SMEs, which dominate economic activity in many jurisdictions and remain unaffected.
