What you need to know: A UK £150k+ City professional's tax picture, 2026/27
Quick answer: A UK additional-rate earner on £150,000 in 2026/27 takes home approximately £90,000/year (£7,500/month) on a standard tax code. Marginal rate on next £1 : 45% income tax + 2% NI = 47%. The 60% trap (£100k-£125,140) already cost ~£10,000 in extra tax on the slice between £100k and £125,140. Tapered Annual Allowance…
Key points:
- Ignoring the 60% trap. Many £110-125k earners are unaware they're paying 60% marginal rate. Pension contributions to escape the band are usually the most valuable financial move at this income level.
- Letting RSU sales create CGT bills above the £3,000 AEA. Sell-to-cover at vest, then drip-sell remaining over years using AEA each year, OR move into ISA over 4-5 years using bed-and-ISA.
- Treating HICBC as inevitable. Pension contributions reduce ANI £-for-£. A £20k pension contribution can eliminate HICBC entirely.
A UK additional-rate earner on £150,000 in 2026/27 takes home approximately £90,000/year (£7,500/month) on a standard tax code. Marginal rate on next £1: 45% income tax + 2% NI = 47%. The 60% trap (£100k-£125,140) already cost ~£10,000 in extra tax on the slice between £100k and £125,140. Tapered Annual Allowance reduces pension contribution allowance for "adjusted income" above £260k. Most City professionals at this level should max pension, EIS/VCT and capital efficiency rather than chase incremental salary.
The headline numbers at £150k
| Component | Annual |
|---|---|
| Gross salary | £150,000 |
| Income tax (zero PA — fully tapered) | −£52,460 |
| Employee NI (8% on basic-rate band, 2% above) | −£5,012 |
| Take-home before pension and other deductions | £92,528 |
That's an effective tax rate of 38.3%. The Personal Allowance has been fully tapered away (taper completes at £125,140), so every £1 of income is taxed from the first penny.
At this income level the standard tax code is usually 0T (no PA) or has manual adjustments. Many City employees also receive RSUs, performance shares, options and bonuses which are taxed in addition to base salary.
The 60% trap — what it already cost between £100k and £125,140
The Personal Allowance tapers by £1 for every £2 of income above £100,000, fully removing it at £125,140. Combined with 40% income tax on the slice and 2% NI:
£0.80 of income tax (40%)
£0.04 of NI (2%)
£0.40 of lost PA × 40% = £0.16 extra tax
Total tax on £2 = £1.00 — that's a 60% marginal rate on this £25,140 band.
Cumulative cost of crossing the £100k threshold to £125,140 = £10,056 of extra tax vs the £50k-£100k band.
Salary sacrifice into pension is the dominant defence at this band. £25,140 of pension contributions can completely restore the PA, saving up to £15,000 of tax.
Tapered Annual Allowance — the £260k threshold
The pension Annual Allowance (£60,000 for 2026/27) tapers above £260,000 of "adjusted income" (salary + bonuses + employer pension + benefits). For every £2 of adjusted income above £260k, the AA reduces by £1, until it hits the £10,000 floor at £360,000.
| Adjusted income | Annual Allowance |
|---|---|
| £200,000 | £60,000 (full) |
| £260,000 | £60,000 (just below taper) |
| £300,000 | £40,000 |
| £340,000 | £20,000 |
| £360,000+ | £10,000 (floor) |
Contributions above the tapered AA trigger an Annual Allowance Charge — tax-relieved going in, then taxed at marginal rate as the charge.
RSUs, bonuses and CGT on share schemes
Tech and City employees commonly receive a mix of base salary, cash bonus, RSUs (Restricted Stock Units) and ESPP (Employee Share Purchase Plans). Tax treatment varies:
| Share scheme | Income tax at vest/exercise? | CGT on later sale? |
|---|---|---|
| RSUs (standard) | Yes, full market value at vest | Yes, on gain above vest value |
| Approved Share Option (CSOP) | No, if held 3+ years and within £60k cap | Yes, on full gain |
| EMI options (eligible companies) | No, if held 2+ years | BADR at 10% (up to £1m lifetime) |
| Sharesave (SAYE) | No, if held to maturity | Yes, on gain above option price |
| SIP (Share Incentive Plan) | No, if held 5+ years | No, if held continuously in SIP |
Most large US tech and bank employers use standard RSUs — income tax + employee NI on full vest value, then CGT on later sale. Many City professionals immediately sell-to-cover the tax then hold the rest, which is sensible diversification.
The four decisions worth making at £150k+
- Salary sacrifice to maximum pension AA every year. Below £260k adjusted income, full £60k AA available. Use the full amount unless you have specific reasons not to (LSA at £268k, retirement timing, MPAA already triggered). Pension is the single most tax-efficient saving for higher earners by a wide margin.
- EIS / VCT for tax efficiency beyond pension. EIS gives 30% income tax relief on up to £1m of investment (£2m if knowledge-intensive). VCT gives 30% on up to £200k. Both have tax-free dividends/gains within the wrapper. Risk is real — these are early-stage companies — but the tax efficiency for additional-rate payers is unmatched outside pension.
- Mortgage offset and capital efficiency. At 5-7% mortgage rates, mortgage overpayment generates a guaranteed 5-7% post-tax return — equivalent to ~12% pre-tax for an additional-rate earner. Often beats marginal investments outside pension. Worth modelling against ISA returns.
- Capital Gains Tax efficiency — every £3,000 AEA per spouse every year. A higher earner couple has £6,000/year of tax-free gains capacity. Crystallising £6,000/year of growth and rebuying in tax-sheltered wrappers (ISA, pension) systematically reduces lifetime CGT.
Common high-earner mistakes
- Ignoring the 60% trap. Many £110-125k earners are unaware they're paying 60% marginal rate. Pension contributions to escape the band are usually the most valuable financial move at this income level.
- Letting RSU sales create CGT bills above the £3,000 AEA. Sell-to-cover at vest, then drip-sell remaining over years using AEA each year, OR move into ISA over 4-5 years using bed-and-ISA.
- Treating HICBC as inevitable. Pension contributions reduce ANI £-for-£. A £20k pension contribution can eliminate HICBC entirely.
- Forgetting tapered AA in bonus years. A £100k bonus on a £180k base creates £280k adjusted income — AA taper kicks in. Pre-bonus planning is critical.
- Skipping EIS/VCT because of risk perception. A diversified VCT portfolio across 5-10 trusts averages risk and the 30% income tax relief plus tax-free dividends compounds. Many additional-rate payers should hold 5-10% of net worth here.
