Pinagtibay ng Marshall Islands ang Economic Substance Regulations na naaangkop mula ika-1 ng Enero 2019. Gayunpaman ito ay kagiliw-giliw na tandaan na:
- ito ay mahigpit na nalalapat sa mga nauugnay na aktibidad (distribution at service center business, negosyo sa pagpopondo at pagpapaupa, negosyo ng punong-tanggapan, may hawak na negosyo ng kumpanya, negosyo sa intelektwal na ari-arian, negosyo sa pagpapadala, negosyo sa pagbabangko, at negosyo ng insurance)
- holding company business is defined as pure equity holding company
- a pure equity holding company is subject to a reduced economic substance test
- the entities must provide the relevant information kung requested by the Registrar
- it seems to apply to Master Series LLC only (and not each Series)
- an entity does not have to satisfy the economic substance requirement if the entity can claim tax residence elsewhere.
