UK Tax Year 2026/27: Income Tax Bands and Thresholds Explained

The 2026/27 Income Tax Framework

The UK income tax year runs from 6 April 2026 to 5 April 2027. For England, Wales and Northern Ireland the rates and thresholds are identical to 2025/26 — a continuation of the freeze first announced in the 2021 Autumn Budget and extended repeatedly since.

England, Wales and Northern Ireland — 2026/27

Taxable income is your total income minus allowable deductions (pension contributions, Gift Aid donations) and minus the Personal Allowance itself.

The PA taper: £100,000 – £125,140

Within the higher-rate band, there is a sub-zone from £100,000 to £125,140 where the Personal Allowance is withdrawn at £1 for every £2 of income above £100,000:

• At £100,000: full PA of £12,570
• At £112,285: PA reduced to £6,427 (£12,570 − £11,570/2 error: (£112,285 − £100,000)/2 = £6,143 reduction)
• At £125,140: PA = £0 (fully tapered)

The effective marginal rate in this range is 60% (40% higher rate tax + 20% on the income that replaced lost PA).

The Threshold Freeze: What It Actually Costs You

The freeze at 2021/22 levels means that as wages grow, a larger share of income is taxable. This is sometimes called "fiscal drag."

Example: salary growing from £35,000 to £45,000 (2021–2026)

The effective rate rose from 12.8% to 14.4% — not because rates changed, but because the threshold didn't move with earnings.

How many extra taxpayers?

The OBR estimated in 2022 that freezing thresholds to 2027/28 would pull an additional 3.2 million people into paying income tax and 1.7 million into the higher-rate band — equivalent to threshold increases of approximately 15% (RPI inflation over the period). As of 2026, the majority of those bracket-creep effects have materialised.

Scotland 2026/27 Income Tax

Scotland sets its own rates and bands on non-savings, non-dividend income (earned income, rental income, pensions). The Scottish Fiscal Commission and Scottish Government set these through the Scottish Rate Resolution. For 2026/27:

Scottish taxpayers have a prefix S on their tax code (e.g. S1257L).

Scotland vs England — the gap at key salaries

The divergence at £50,000 is most stark for average higher earners — Scotland's 42% Higher rate starts at £43,662 vs England's 40% at £50,270.

Wales 2026/27

The Welsh Government has voted to keep Welsh Income Tax rates identical to England in 2026/27. Welsh taxpayers have a C prefix on their tax code (e.g. C1257L). There is no practical difference in income tax liability from England.

---

Northern Ireland 2026/27

Northern Ireland uses the same income tax rates as England and Wales. Devolved tax-varying powers have not been exercised for income tax. NI taxpayers have the standard 1257L code unless HMRC separately adjusts it.

Practical Examples for 2026/27

Example 1: Full-time employee, £38,000 salary

Example 2: Higher earner, £65,000 salary

Example 3: Entering the 60% taper zone, £105,000 salary

What to Do About the Freeze

The freeze creates specific opportunities:

Salary sacrifice into pension: contributions reduce your adjusted net income, keeping you in lower bands or below key thresholds (£100k PA taper, £60k HICBC threshold).

Marriage Allowance: if one partner has unused PA (income below £12,570) and the other is a basic-rate taxpayer, transfer £1,260 of PA to save up to £252 per year.

ISA maximisation: income from ISAs does not count toward adjusted net income — important for those close to the £100k taper or £60k HICBC start.

Gift Aid: donations under Gift Aid are made as if from post-tax income; higher-rate taxpayers can claim the 20% difference via Self Assessment, and the donation reduces adjusted net income.
