Singapore Parliament passes 2026 Finance Bill with Pillar Two amendments

Singapore’s Parliament passed the Finance (Income Taxes) Bill 2026 (Bill No. 22/2026) on 6 October 2026. The Bill contains a substantial package of amendments to the Multinational Enterprise (Minimum Tax) Act 2024 (MMTA), including statutory powers for Singapore’s implementation of the OECD Side-by-Side Safe Harbour, revised GloBE Information Return (GIR) filing and exchange rules, return-exemption powers and detailed domestic top-up tax accounting provisions.

Parliamentary passage is not the same as commencement. The Bill still requires presidential assent and publication as an Act. Several provisions will then depend on ministerial commencement notifications or regulations. This article therefore describes the passed Bill, not law already in force. The official second-reading speech confirms the policy purpose of the amendments, while the Bill supplies the operative text.

From consultation proposal to passed Bill

Singapore consulted in June 2026 on a narrower set of Side-by-Side changes. As discussed in our earlier analysis, those proposals focused on allowing the safe harbour to apply to stateless entities and on a dynamic reference to OECD qualification decisions. The introduced Bill, first read on 8 September, is materially broader. Clauses 36–50 now amend the MMTA across definitions, filing, exchange, penalties, exemptions, appeals, secrecy, regulation-making and DTT accounting.

The renumbering is also important. The Side-by-Side provisions appear in clauses 38 and 49(b) of Bill 22/2026, rather than the clause numbers used in the consultation draft. The remaining clauses are not merely drafting support for that safe harbour; they establish separate compliance and administrative rules that groups will need to map into Singapore processes.

Side-by-Side Safe Harbour

Clause 38 amends MMTA section 20 so that a GloBE safe harbour may apply in relation to a stateless entity. That change is needed for Singapore to give effect to the Side-by-Side Safe Harbour, which uses a simplified jurisdictional effective tax rate test and can require stateless entities to be taken into account. Clause 49(b) allows regulations to identify the relevant OECD qualification material by reference to the version published on the OECD website at a specified time.

The Bill treats both provisions as effective from 1 January 2026. The second-reading speech states that US-parented groups qualifying for the Side-by-Side Safe Harbour would be exempt from Singapore’s multinational enterprise top-up tax (MTT), while Singapore’s domestic top-up tax (DTT) would continue to apply. That distinction follows the architecture of the safe harbour: it protects qualifying groups from specified IIR and UTPR exposure, but does not disapply a jurisdiction’s QDMTT.

The compliance package goes further than the safe harbour

Clause 36 expands the statutory definition of a GIR so that it can include an equivalent return required under the domestic law of a foreign jurisdiction for a qualified UTPR, QDMTT, MTT or DTT. Clauses 40 and 41 then separate two legal questions: whether the return is required under the foreign jurisdiction’s domestic law, and whether Singapore has a qualifying exchange relationship with that jurisdiction. The distinction is significant because central filing relies on both an obligation to file and an effective mechanism for Singapore to receive the information.

The Bill also creates a local fallback where exchange does not deliver the return. These amendments move Singapore beyond the consultation-stage safe-harbour proposal and towards an integrated statutory framework for administration of the first MMTA reporting cycles.

Local GIR fallback where exchange fails

Clause 42 inserts a new MMTA section 40(4A). Where a GIR has been filed centrally outside Singapore but is not received by the Comptroller within the required period under a qualifying competent authority agreement, the Comptroller may require the designated local GIR filing entity to file it in Singapore. The deadline specified in the notice must be at least one month after the notice is given.
