In September 2021 the prime minister announced a 1.25% rise in National Insurance Contributions (NICs) and dividend tax from 6 April 2022. As the dust settles, it becomes clear that the tax rises are wider-reaching measures than they first appeared.  

National Insurance

The government paper ‘Building Back Better: Our Plan for Health and Social Care’ Outlines an increase of 1.25% in primary and secondary Class 1, and Class 4, NICs from 6 April 2022.

HMRC has updated their guidance covering rates and thresholds for employers. This update makes it clear that the 1.25% increase will also apply to other types of NICs:

In both cases, the current 13.8% rates will become 15.05% from 6 April 2022.

NI classes 2 and 3 are not affected by the proposed increase.

On NICs thresholds: the government has chosen not to reveal the thresholds at which NICs applies from 2022-23. This makes it difficult to accurately measure the actual cost of the proposed rise.

In addition to the increase in NI rates, it was Announced that Dividend tax will also increase by 1.25% from 6 April 2022.

A wider consequence of this is in respect of loans to participators in close companies.

Dividend allowance & thresholds: the government's paper also fails to mention whether there will be any changes to the tax free dividend allowance for 2022-23 and does not shed any light on the changes to the basic or higher rate tax bands either. The thresholds are normally left to the chancellor to announce at the Budget and as with the NICs increase, this means that no one can accurately say how much more anyone receiving a fixed rate dividend might actually pay.

The announced changes will also apply to Scottish taxpayers.

Due to the Scottish NIC thresholds being linked to the UK, Scottish taxpayers with employment income between the Scottish and UK higher-rate Income Tax thresholds (£43,662 and £50,270 respectively in 2021-22), will be liable to a marginal tax rate of 54.25% on that part of their income, from April 2022.
