As the Minister said, the Bill will prevent any increase in the current rates of class 1, class 1A and class 1B national insurance contributions paid by employees and employers for the duration of the current Parliament. It will also provide that, for each year, the annual upper earnings limit cannot exceed the higher-rate threshold, which is the sum of the personal allowance and the income tax basic rate. All that is very sensible. There is nothing wrong, in principle, with any Government’s providing certainty in the tax code for the duration of their term in office. However, we clearly do not need legislation to do that.
As has already been said—so I shall say it only once—the Bill is a gimmick. It also demonstrates, in many ways, a lack of confidence. I shall say more about that shortly, but the key point is that placing such an arbitrary and unnecessary restriction on the Government’s ability to respond to unforeseen events may yet come back to haunt them.
The Bill results from the Finance Bill, which was published in July, and which provides for the tax lock on national insurance contributions, income tax and VAT. As was said earlier, it is intended to apply to a tax year that comes after the date of the Bill’s Royal Assent and before the first general election after that date. The time scope is therefore rather limited. There is also a technical issue. This is a separate Bill; the measures are not in the Finance Bill because statutory provisions for NI cannot be included in it.
However, none of this should be any surprise to us. The Conservative manifesto said that in government the Tories would not increase the rate of VAT, income tax or NICs in this Parliament. That should have been enough; the legislation is not required. In a speech ahead of the general election the Prime Minister confirmed that the tax lock also meant there would be no extension to the scope of VAT or any increase in the ceiling set for the main rate of NICs for employees.
