Budget 2025: Extending the Threshold Freeze

The Institute for Fiscal Studies (IFS) has returned to a favourite topic, the impact of threshold freezes. Good timing (or co-incidence?). On the day (Friday 14 November) that the Financial Times reported the Chancellor has “ditched plan to increase income tax rates in the Budget”, the Institute for Fiscal Studies (IFS) issued a comment piece examining the consequences of extending the income tax threshold freeze to 2029/30.

One of the simpler ways to realise a decent amount of extra cash is by extending the income tax threshold freeze to 2029 / 30. However, a freeze still carries significant political risks: in the last Budget the Chancellor said, “Having considered this issue closely I have come to the conclusion that extending the threshold freeze further would hurt working people.”

The IFS makes the following points about an extended freeze of thresholds:

  • Relative to what was once the norm of threshold indexation, the current income tax freeze to 5 April 2028 is expected to raise £39bn a year in 2029/30 (similar to the impact of increasing all income tax rates of by 3.5 percentage points).

  • To this can be added the current National Insurance (NIC) threshold freezes for employees (from July 2022) and the self-employed (April 2023) which are set to raise £3bn a year in 2029/30.

  • If the Chancellor chose to keep all currently frozen NICs (including employer) and income tax thresholds frozen for two further years, this would raise a further £8.3bn a year by 2029/30 (much the same as a 1p increase in basic rate tax).

  • An extension would bring the total number of people subject to income tax at higher rates (i.e. marginal rates of 40% or above) to 10.1m million. That represents an increase of 790,000 compared with current policy and a 4.8m increase relative to if there had been no freezes.

An extended threshold freeze is an easy way out for the Chancellor – effectively delegating her tax policies to rising inflation.
