Tax signals power shift globally

- ‘Lex’ comment

Attempting to fix the broken internatio­nal corporate tax system is a Sisyphean task. But a new model for taxing multinatio­nals put forward by the Biden Administra­tion could put the brakes on decades of plummeting tax rates and aggressive planning.

The US blueprint features a 21 per cent global minimum corporate tax rate and a proposal to reallocate some tax paid by the largest, most profitable companies to countries where they make their sales.

It is similar to ideas kicked around by the OECD in recent years. But the push to redistribu­te a slice of tax revenues would apply to a broader group of businesses. That is likely to make the policy more palatable to US lawmakers as it would no longer single out US digital companies.

The model would also defuse the internatio­nal row over digital taxes fuelled by the imposition of national levies in Britain, France and elsewhere. That would be a relief to some US tech companies, though others such as Microsoft might be losers. While digital taxes home in on its LinkedIn subsidiary, its entire business is likely to be in the scope of the US proposal.

Just as radical is the US bid to put a stop to tax competitio­n, by encouragin­g its peers to adopt a high minimum tax rate. That would hit countries such as Ireland, where US multinatio­nals play an outsized role.

Success is not assured. Getting the plan through the US Congress will be a challenge. Internatio­nally, cooperatin­g over tax rates would mean breaking a decades-old habit of competing for company bases. Much horse-trading will be needed to reach agreement. Expect the minimum rate to be toned down, from the mooted 21 per cent to perhaps 17 per cent or so.

Nonetheles­s, the US has enough clout to engineer a deal. The revenue raised is likely to be about US$100 billion ($141.8b) — or 4 per cent of global tax revenues — shouldered by at most 200 businesses.

The decision to focus tax rises on a relatively small group is a recognitio­n of the winner-takes-all nature of the global economy. These measures, if adopted, would signal a shift in the balance of power.
