Ah yes, “various income tax rates”, that’s definitely not a reference to the top rate of income tax… which is £125k. Fuck off. I don’t give a shit about people earning that much having to pay more tax.

Thresholds, not rates. And, as you'd expect, freezing them hits the poorest the hardest.

The effect of freezing tax thresholds:

The combined impact of headline tax changes, policy roll-outs and frozen taxes and benefits by 2025–26 is broadly regressive, with the poorest seeing income falls of 2.8% of income and the richest falls of only 1.1%. Headline cuts to income tax and National Insurance will benefit higher-income households who are more likely to get more of their income from employment, while the poorest tenth of households will gain only £13 per year from these measures. Because some tax thresholds and – especially – benefits values are indefinitely frozen, the impact of freezes only grows over time. As a result, by 2030–31 the total changes to the tax and benefit system are more clearly regressive, with the highest-income tenth seeing a 1.3% fall in income and the lowest-income tenth a 4.7% fall.
