An interesting development in the UK election campaign today, as the opposition Labour party will pledge to end ‘non-domicile’ tax status – an 18th century relic which allows residents to exempt their foreign income from tax, provided they can make at least some (often highly tenuous) connection to some other state.
It’s heartening to see tax in the centre of the discussion, not least given the minimal attention that has been paid to the UK pursuing the most extreme tax-averse austerity of any leading country (the only country to cut spending more than it cut the deficit).
Unsurprisingly, media attention has focused on the likely revenue impacts and the behavioural effects. Tax accountant Richard Murphy and tax lawyer Jolyon Maugham both suggest a top end revenue impact around £4 billion, falling with behaviour change to £1 billion or so. [Delete as appropriate: great minds/fools etc.]
The revenue numbers may be relatively small, but they’re not really the main point. Abolishing non-dom status would remove a clear injustice in the system, a deliberately created horizontal inequality in treatment of otherwise similar people.
More importantly, it responds to Piketty’s case for a wealth tax:
The primary purpose of the capital tax is not to finance the social state but to regulate capitalism. The goal is first to stop the indefinite increase of inequality of wealth, and second to impose effective regulation on the financial and banking system in order to avoid crises.
Absent a tax, even at a nominal 0.01%, data may not be collected and so policymakers will lack information about the distribution which might lead them to set policies to tackle inequality.
Aside from the aspect of tax injustice, non-dom status has been pernicious in part because it has taken a deal of high-income individuals’ income out of tax and other data – so that the actual distribution is simply not known.
If we can envisage scenarios in which policymakers may wish to address the (top end of the) distribution, then the absence of this data is an obstacle. In fact, this is one more example of the phenomenon of Uncounted – where the power of an elite group, in this case, allows them to go uncounted and this in turn militates towards higher inequality.
Finally, the existence of non-dom status is iconic – a clear message that the UK wishes to retain its role at the heart of global tax haven activity, providing differential tax and transparency treatment to a certain elite. Knocking non-dommery on the head would build the credibility of, for example, the outgoing government’s important efforts to address financial secrecy worldwide through the G8 and beyond.
