Taxes fund essential infrastructure like schools, healthcare and roads. Like citizens, companies benefit from use of this public money – company workers are kept healthy by the NHS, and products get from A to B on motorways built by the government, all funded through taxes.
But many big companies don’t prioritise giving back a fair share of their earnings.
According to the Tax Justice Network’s 2024 calculations, the UK government loses £33bn a year in taxes to multinational corporations and wealthy individuals moving their profits and finances abroad. That’s around half of the UK’s entire education budget each year.
How do companies use tax havens?
The most common way big companies avoid tax is by moving their profits out of the countries where they genuinely do work, and into tax havens.
1. Subsidiaries in tax havens
Big companies often have dozens, hundreds or even thousands of companies in their company group. If they ‘register’ or ‘incorporate’ some of these companies in jurisdictions with low taxes, it can help the whole company group avoid paying taxes.
If one of these companies is based in a tax haven like Bermuda, other companies in the family might send their profits to that family member in Bermuda – so the whole company group ends up paying less taxes overall.
2. Parent company in a tax haven
At the very top of the big company group is one single ‘parent company’, which owns all of the others. Sometimes this ‘top dog’ company is referred to as the ‘ultimate holding company’, or UHC, because it holds power over all the companies beneath it.
If that parent company is incorporated in a tax haven, then it makes it even easier for the whole family to avoid having to pay taxes.
How can I spot tax avoidance?
If a firm carries out nearly all of its work in one country, but its parent company is registered in a known tax haven, it should ring alarm bells. For example, if it has factories, shop fronts and head offices in the UK and then a surprising ‘financial services’ company in Bermuda, this suggests it could be profit shifting.
A company incorporated in a country with low taxes will not always be avoiding taxes. Specsavers for example is incorporated in Guernsey, a well-known tax haven. At first glance this seems highly suspect – Guernsey is a tiny island, with a population of around 65,000 people, so why would a big company have operations there? If you look deeper, however, you find that one of Specsavers’ founders, Mary Perkins, moved there to be closer to her retired parents, and there’s been documented evidence that Specsavers actually pays a pretty high amount of tax.
But usually, there’s no retired parent to explain the company being in a tax haven – and if the company doesn’t provide a good explanation, it’s clearly a high risk case for tax avoidance.
