If Like Me,

you had a company in your working life,

how come I had never heard of this tax avoidance scheme until now? it is called 'the double Irish with a Dutch sandwich', "it is employed by certain large corporations, involving the use of a combination of Irish and Dutch subsidiary companies to shift profits to low or no tax jurisdictions. The scheme involves sending profits first through one Irish company, then to a Dutch company, and finally to a second Irish company headquartered in a tax haven. This technique has made it possible for certain corporations to reduce their overall corporate tax rates dramatically."

Example provided by Reuters: 

AMSTERDAM (Reuters) - Google moved 19.9 billion euros or $22.7 billion, (notice we are talking of Billions, not millions!) through a Dutch shell company to Bermuda in 2017, as part of an arrangement that allows it to reduce its foreign tax bill, according to documents filed at the Dutch Chamber of Commerce...

The subsidiary in the Netherlands is used to shift revenue from royalties earned outside the United States to Google Ireland Holdings, an affiliate based in Bermuda, where companies pay no income tax.

The tax strategy, known as the “Double Irish, Dutch Sandwich”, is legal and allows Google to avoid triggering U.S. income taxes or European withholding taxes on the funds, which represent the bulk of its overseas profits, Google responds that they comply with tax laws, unfortunately that is true, just think of all of the good that governments could do with the money raised in taxes, if large companies did not exploit loopholes in the law.
