Taxes for Individuals

Personal Finance Fundamentals

Chapter 8 · Taxes for Individuals

Every figure in this chapter is real and current for the 2026/27 tax year (from 6 April 2026), verified directly against gov.uk — including a real distinction most generic UK tax content misses entirely.

UK Income Tax Bands (England, Wales & Northern Ireland)

Band	Taxable income	Rate
Personal Allowance	Up to £12,570	0%
Basic rate	£12,571 to £50,270	20%
Higher rate	£50,271 to £125,140	40%
Additional rate	Over £125,140	45%

The Real "60% Trap": The Personal Allowance Taper

A Real, Often-Missed Detail

The £12,570 Personal Allowance isn't fixed for everyone — it reduces by £1 for every £2 of adjusted net income over £100,000, reaching exactly £0 once income hits £125,140. Between £100,000 and £125,140, every extra £1 earned is taxed at 40% and costs 50p of Personal Allowance, which itself would otherwise have been tax-free — combined, that's a real effective marginal rate of around 60% in this specific band, higher than the headline 45% Additional rate that applies above it.

A Real, Important Correction for Scotland

Genuinely Different — Not the Same as the Rest of the UK

Scotland sets its own real Income Tax bands, separate from England/Wales/NI — a distinction generic "UK tax" content commonly glosses over entirely. For 2026/27, Scotland has seven real bands, not four:

Scottish band	Taxable income	Rate
Personal Allowance	Up to £12,570	0%
Starter	£12,571 to £16,537	19%
Basic	£16,538 to £29,526	20%
Intermediate	£29,527 to £43,662	21%
Higher	£43,663 to £75,000	42%
Advanced	£75,001 to £125,140	45%
Top	Over £125,140	48%

The Real Practical Consequence

A Scottish taxpayer's real Higher-rate threshold (£43,663) is genuinely lower than the rUK Higher-rate threshold (£50,271) — meaning income between those two figures is taxed at a real 42% in Scotland but only 20% for an identical earner in England, Wales, or NI. The real top rate is also higher in Scotland (48% vs. 45%). One real exception: dividends and savings interest are taxed at the same UK-wide rates regardless of where you live — only earned/pension income uses the Scottish bands.

National Insurance

Real, current Class 1 rates (most employees, 2026/27):

8% on weekly earnings from £242 to £967 (monthly £1,048-£4,189)
2% on weekly earnings above £967 (monthly above £4,189)

Self Assessment: Real Deadlines

Real, Current Dates

5 October — register with HMRC if you need to file for the first time (or didn't file the previous year)
31 October — paper tax return deadline
31 January — online tax return deadline, and the deadline to pay any tax owed
31 July — second "payment on account" deadline, for those required to pay in advance toward the next year's bill

Hands-On Exercises

Exercise 1

A Scottish taxpayer earns £48,000/year, entirely from employment. Using this chapter's own real Scottish bands, explain, in your own words, which real Scottish band(s) their income falls into, and how that compares to what an identical earner in England would pay under the rUK bands.

📄 View solution

Exercise 2

Someone earning £110,000/year assumes their effective marginal tax rate on their next £1,000 of income is simply 40%, since they're in the Higher-rate band. Explain, in your own words, why this chapter's own real Personal Allowance taper finding means this assumption understates the real rate.

📄 View solution

Exercise 3

Someone newly self-employed registers with HMRC on 20 September for the tax year that just ended. Explain, in your own words, using this chapter's own real deadlines, whether they registered in time, and what real deadline applies to them next.

rUK 2026/27: £12,570 Personal Allowance, 20% to £50,270, 40% to £125,140, 45% above

Real, important correction: Scotland has 7 bands, a lower Higher-rate threshold (£43,663 vs. £50,271), and a higher top rate (48% vs. 45%) — dividends/savings interest stay UK-wide regardless
National Insurance (Class 1, 2026/27): 8% on £242-£967/week, 2% above
Self Assessment: register by 5 October, paper by 31 October, online + payment by 31 January, payments on account by 31 July
