If Rachel Reeves must raise taxes, the basic rate of income tax is the worst place to start

Posted on

The Telegraph reported this morning that the National Institute of Economic and Social Research (NIESR) has told Rachel Reeves that raising income tax would be the least damaging way to fill what it described as a £30 billion hole in the public finances. They note:

Adding 3p to the basic and higher rates of income tax would be less harmful than ramping up VAT, corporation tax, or a raft of smaller taxes, the institute said.

This is the route to even worse outcomes from Labour than anything they have tried before.

First, let me start with the obvious. There is no £30 billion hole in the public finances. The UK government is the issuer of the currency. It cannot run out of money. What it can run out of are real resources, whether they be labour, materials, skills, or the planet's capacity to sustain what we do. The constraint is physical, not financial. Talking about a hole in the public finances is a political choice, not an economic truth.

But then let's play along with the question NIESR has set. If Reeves believes she must raise taxes, and she clearly does, for political and institutional reasons, the real issue is not whether to raise them, but who should pay.

First, not all income tax rises are equal

Adding 3p to the basic rate would penalise millions of people already struggling with stagnating wages, stealth fiscal drag, and collapsing public services. This would be a tax rise on the lowest paid who already shoulder a disproportionate share of the burden in proportion to their real capacity to pay.

But there are alternatives within the income tax system itself. In the Taxing Wealth Report, I showed that almost all the real tax giveaways of recent decades have gone to the top few per cent of the population. That has not been through the headline rate of income tax, but through the myriad ways the wealthy convert income into something that is not taxed like income at all, or through which they can claim disproportionate tax allowances and reliefs. Not all taxes are equal in that case, and a rebalancing is required. The NIESR seem to be ignoring that, as if they are deliberately feeding the prejucies of The Telegraph

Second, tax wealth, not work

If Reeves wishes to make the tax system fairer and raise substantial revenue, she should begin where the money really is, which is in wealth, and not wages. Four straightforward reforms would achieve more than any blanket increase in income tax:

  1. An investment income surcharge. Apply an additional tax rate to income from interest, dividends, and rents, sources overwhelmingly concentrated among the wealthiest households, largely to address the fact that national insurance is not paid on these sources, and Reeves could find much of the tax she is supposedly looking for.

  2. Equalise capital gains tax with income tax. There is no moral or economic justification for favouring returns from ownership over returns from labour. These rates should be the same.

  3. Charge VAT on banking and financial services. These sectors are currently exempt, which favours the wealthy who are the predominant purchasers of their services.

  4. Restrict pension tax reliefs for high earners. The subsidies here are hugely regressive, turning pension contributions into tools of tax avoidance rather than social insurance.

Together, these measures could raise more than £50 billion in my estimate, while improving fairness and efficiency. They would also help to begin closing the yawning gap between earned and unearned income, which is a gap that distorts markets and erodes the legitimacy and social acceptability of the tax system in the eyes of most people, which matters when they are now very angry about that fact and are moving towards Reform as a result.

Third, stop pretending tax rises fund spending

Even if Reeves were to adopt all these proposals, the purpose of doing so should not be to plug a hole. Taxes do not fund spending. They serve to reclaim some of the money the government has already injected into the economy through its own expenditure, to manage inflation, shape behaviour, and express social priorities. The point of tax is to redistribute both income and power, not to fill imaginary fiscal gaps.

The real tragedy is that Labour still speaks as though it is constrained by some kind of household-sized budget. And Reeves insists that every pound of public investment must be fully funded as if she were managing a corner shop rather than steering a sovereign government with direct control over its own monetary operations.

What follows

If Reeves genuinely believes that Britain needs better public services, and she frequently says she does, then she must stop treating taxation as a penalty and start using it as an instrument of fairness.

Raise taxes, by all means, but only on those who can easily afford it. And do so for the right reason: not to balance the books in some mistaken way, but to rebalance the economy and restore legitimacy to public finance.
