Is the Pay Rise Worth It?
Moving from £150,000 to £180,000 is a gross increase of £30,000. But after income tax and National Insurance you actually take home £15,900 more per year — that’s £1,325 extra per month. You keep 53% of the rise under 2025/26 rules (thresholds frozen to 2028); because those thresholds are frozen, the same figures apply for 2026/27.
| Where the £30,000 rise goes | Amount |
|---|---|
| Gross increase | £30,000 |
| Extra income tax | -£13,500 |
| Extra National Insurance | -£600 |
| Net gain in your pocket | £15,900 (53%) |
Both salaries sit above £125,140, so the personal allowance is fully tapered away on both sides and the notorious 62% trap between £100,000 and £125,140 is already behind you. Every £1 of the move from £150,000 to £180,000 is taxed at the additional rate: 45% income tax plus 2% National Insurance, a flat 47% marginal rate. You keep 53p in the £1 — which is exactly why the kept share works out at 53%. There are no further cliff edges between these two figures; the maths is brutal but at least it is linear.
For context, £150,000 is about 3.8× and £180,000 about 4.6× the UK median full-time salary of £39,039 (ONS Annual Survey of Hours and Earnings, April 2025). Comparisons with typical pay stop being useful at this level — what matters is how efficiently each extra pound is converted into net income, pension and assets.

Figures are for England, Wales and Northern Ireland under 2025/26 rates — thresholds are frozen to 2028, so they hold for 2026/27 as well. Scottish income tax bands differ. Pension contributions and student loans are excluded here; both would change the picture in your favour or against it respectively.
Pension Moves That Change the Maths
With the personal allowance long gone, pension contributions no longer rescue it — but they still earn relief at your 45% marginal rate, so £1 inside a pension costs about 53p of net pay (before NI savings if your employer offers salary sacrifice). The standard annual allowance is £60,000 for 2025/26. Beyond pensions, ISAs, and for some people VCT or EIS investments, become the main shelters worth discussing with an adviser — our high-earner tax tips article covers the full toolkit.
What the Difference Means in Practice
An extra £1,325 a month is substantial: it can carry a significantly larger mortgage, cover private school fees for a child, or fill most of a £20,000 ISA within the year. Salaries around £180,000 usually mean director-level roles, senior specialist medicine, or partner-track professional services — moves that often bring bonus and equity elements on top.
Is the Jump Worth It?
When weighing a move from £150,000 to £180,000, look past the headline number. Employer pension contributions are usually a percentage of the higher salary, so the rise compounds inside your pension even while the taxman takes his share of the cash. If you are still repaying a student loan, Plan 2 adds another 9% to the marginal rates above, and at a typical 4.5× income multiple, the difference in borrowing power is about £135,000. Weigh working hours, bonus structure and equity too — at this level they often move more money than base salary. See the full standalone breakdowns: £150,000 after tax and £180,000 after tax.
