Editor’s note: This is an educational explainer about how real estate investment trusts on the Singapore Exchange generally work. It is general information, not investment advice, and does not describe any specific current event, company, or security.
A single number, 90 percent, sits at the center of how hundreds of shopping malls, office towers, warehouses and data centres in Singapore are owned. It is not a marketing figure or a return target. It is a tax condition, and understanding it explains why real estate investment trusts, commonly called REITs, look and behave so differently from ordinary companies listed on the same exchange.
The trust structure, not a company
Unlike most listed businesses, a Singapore REIT (often shortened to S-REIT) is not, at its legal core, a company. It is a trust. A trustee, typically a licensed trust company, holds the underlying real estate assets on behalf of unit holders, who are the equivalent of shareholders but are technically called “unitholders” because they own units in a trust rather than shares in a corporation. Day-to-day property decisions, acquisitions and leasing strategy are handled by a separate REIT manager, which is usually a company that earns fees for managing the portfolio.
This three-way separation, trustee, manager and unitholders, is a structural feature required under the Monetary Authority of Singapore’s Code on Collective Investment Schemes, which governs REITs alongside the Singapore Exchange’s listing rules. The trustee’s job is essentially custodial and protective: it holds legal title to the properties and is meant to safeguard unitholder interests, while the manager runs the business of the portfolio. This division exists precisely because a REIT pools money from many investors to buy income-producing property, and regulators wanted a built-in check between the entity managing the assets and the entity legally holding them.
The 90 percent distribution rule
The feature that most defines an S-REIT, and separates it from an ordinary property company, is the income distribution requirement. To qualify for tax transparency treatment under Singapore’s Income Tax Act, a REIT must distribute at least 90 percent of its taxable income to unitholders, generally on a semi-annual or quarterly basis depending on the trust’s own policy.
“Tax transparency” is the operative concept here. Ordinarily, a company pays corporate tax on its profits, and shareholders may then be taxed again on dividends received. Under the qualifying arrangement for S-REITs, the trust itself avoids being taxed on income that it distributes, provided it meets the 90 percent threshold. This avoids the layer of double taxation that would otherwise apply, and the tax burden shifts largely to unitholders, who may face different treatment depending on whether they are individuals, companies, or foreign investors, and depending on any exemptions in place at a given time.
This is why S-REITs, almost by design, retain very little cash inside the trust. Unlike a typical company that might reinvest a large share of profit into new ventures or build up reserves, a REIT sends the overwhelming majority of its taxable income straight back out to unitholders as distributions. That structural constraint has knock-on effects: because so little income is retained, REITs generally rely on debt and periodic equity fundraising, such as rights issues or placements, to fund acquisitions or major redevelopment, rather than relying on retained earnings the way many other listed businesses can.
Gearing limits and other structural guardrails
Because S-REITs lean on borrowing to grow, regulators impose a leverage ceiling known as the aggregate leverage limit, which caps total borrowings as a proportion of the trust’s total assets. This limit, set and periodically reviewed by the Monetary Authority of Singapore, exists specifically because REITs are structurally predisposed to distribute nearly all their income rather than build equity buffers internally, making their debt levels a closer watch point than for many other companies.
There are further structural rules governing what a REIT can actually own and how it can be run: restrictions on the types of assets and development activities permitted, requirements around related-party transactions between a REIT manager and other entities in its corporate family, and rules governing how often units must be valued. Taken together, these features, the trustee-manager split, the income payout threshold, and the leverage ceiling, are what make an S-REIT a distinct legal and financial vehicle rather than simply a property company that happens to be listed. They shape everything from how a REIT raises capital to how frequently it returns cash to unitholders, and they are the backbone against which any individual S-REIT’s specific terms and performance are ultimately assessed.
