Why does Scotland have different income tax rates?
Under the Scotland Act 2016, the Scottish Parliament gained significant income tax powers — including the ability to set rates and thresholds for all income tax bands (except the personal allowance, which remains reserved to Westminster). The Scottish Parliament uses these powers to fund additional public services and social programmes.
Key differences from England in 2026/27
The most impactful differences are at the Higher Rate (42% in Scotland vs 40% in England) which begins £6,608 earlier in Scotland (£43,662 vs £50,270), and the Advanced Rate band (45% between £75,000 and £125,140) which has no equivalent in England.
What about National Insurance?
National Insurance is not devolved — it is set by the UK Parliament and is identical throughout Scotland, England, Wales, and Northern Ireland. Only income tax rates differ. In 2026/27, Class 1 employee NI is 8% between the Primary Threshold (£12,570) and the Upper Earnings Limit (£50,270), and 2% above that.
