With US tax reform in 2018 introducing significant changes to how US owners of foreign businesses are taxed, advice should be sought to see how these changes affect US owners. In addition, with the announcement last year that the Corporation Tax Cut from 19% to 17% from April 2020 is to be put on hold, this may change some of the planning if a potential high tax exemption is available in the future against the US Global Intangible Low-Taxed Income (GILTI) tax.
What should I do?
If you are a US owner of a foreign business, you should consider the implications that the 2018 US tax reform has on your global tax bill. There are some additional tax considerations such as the GILTI tax, which may lead you to make an election for the company to be transparent, electing to be taxed as a US company, or using alternative tax mitigation techniques. Also with UK Corporation Tax looking like it might remain at 19% for the time being, you should factor this into your planning.
