SWI GVT IIR Tax Rule in Force 2025


On Sep. 4, SWI GVT updated on international supplementary tax.


  • SWI Tax, SWI SECO announced decision to bring the income inclusion rule (IIR) international supplementary tax into force with effect from 1 January 2025.
  • Published expert report of Aug. 23, 2024 commission from Prof. Dr. iur. René Matteotti.
  • This international supplementary tax will complement the Swiss supplementary tax (QDMTT) introduced in 2024, both aim to ensure tax receipts stay in Switzerland.
  • Follows SWI GVT Dec. 2023 ordinance introducing OECD/G20 rate, see #196247.
  • Overview
  • In 2023 citizens, cantons voted in favor of introducing OECD/G20 minimum tax rate in Switzerland, to prevent country foregoing tax receipts in favor of foreign countries.
  • On Sep. 4, 2024, SWI GVT also decided to bring the IIR into force on Jan. 1, 2025.
  • With this tax, profits of foreign subsidiaries of Swiss corporate groups, as well as those of intermediate holding companies of foreign corporate groups, are taxed at 15%.
  • Provided the corporate group's global annual turnover is at least €750 million.
  • If IIR not brought into force, other jurisdictions could tax these foreign profits as per OECD/G20 minimum taxation rule by applying the undertaxed profits rule (UTPR).
  • Most EU member states, UK, Canada, Australia are planning to apply the UTPR from 2025 onwards, following their introduction of both the IRR and QDMTT in 2024.
  • By bringing IIR into force, Switzerland can secure receipts which can then be used to strengthen the country's attractiveness as a business location, provide legal certainty.
  • No UTPR for Now
  • SWI GVT also decided not to bring UTPR into force for the time being, thinks risks of it could outweigh revenue potential, UTPR subject to criticism from a legal standpoint.
  • But will continue to keep a very close eye on international developments with respect to the implementation of the OECD/G20 minimum tax rate.
  • Nov. 2024 Update
  • On Nov. 20, 2024, SWI GVT, Tax announced change to OECD minimum taxation order.
  • At meeting of Nov. 20 Federal Council decided to amend Minimum Taxation Ordinance.
  • It did so in relation to the entry into force of international supplementary tax (i.e. IIR).
  • IIR expands Swiss supplementary tax introduced in 2024; both ensure tax revenue resulting from OECD minimum taxation remains in SWI instead of flowing abroad.
  • Potential tax revenue for entire state initially estimated at 1.5 to 3.5 billion francs; this could be skimmed off by foreign countries if Switzerland were to forego minimum tax.
  • Implementation ensures legal certainty and protects affected corporate groups from additional tax procedures abroad; change effective Jan. 1, 2025, explanation issued.
