The four tax mechanisms acting on this income

For a product manager contractor at £110,000 of gross income on the Ltd Co director route in 2026/27, four mechanisms determine the bottom line:

  1. The Personal Allowance — £12,570 of income at 0% income tax. Above £100,000 of adjusted net income the allowance tapers at £1 lost for every £2 over the threshold, fully eroded at £125,140. At £110,000 of relevant income this row sits inside the taper, with an effective 60% marginal rate on the next £1 (40% income tax + 40% × 50p of lost PA).
  2. The £50,270 higher-rate threshold — income tax jumps from 20% to 40% above this number. Dividend tax simultaneously jumps from 8.75% to 33.75%.
  3. National Insurance — on the salary slice only, at 8% employee + 15% employer above the relevant thresholds. The dividend slice attracts no NI — that is the central source of the Ltd Co tax-efficiency edge.
  4. Corporation tax — 19% on profits up to £50,000, 25% on profits above £250,000, with a 26.5% effective marginal rate in the £50k–£250k band (HMRC marginal-relief formula).

Run those four mechanisms in sequence and the bottom line for this row is £39,440 of net cash plus £60,000 into a pension, against £10,560 of taxes / NI / fees lost through the chain — an effective rate of 9.6%.

Where the optimal extraction sits

  • Corporation tax: £6,896 on £36,295 of post-pay profit.
  • Employer NI: £1,136 on the £12,570 salary (15% above the £5,000 Secondary Threshold).
  • Employee NI: £0 on the same salary (8% main band, 2% above £50,270).
  • Income tax: £0 on the salary (rUK bands, after personal allowance).
  • Dividend tax: £2,529 on the £29,399 dividend (8.75% / 33.75% / 39.35% bands, stacked above salary).

Why this scenario is different

Compared to the closest peer profile — Software contractor at £110,000 — this scenario sits £0 higher on gross income. That moves net cash by +£0, the pension contribution by +£0, and the effective rate by +0%. The effective rate moves only modestly — both scenarios sit inside the same binding tax band. The optimiser shifts £0 of the extraction out of the dividend slice, and £0 out of pension contributions.

Questions this scenario raises

Why does the optimiser disagree with my accountant?

Often because the accountant is optimising salary first, pension second, dividend as residual — three sequential one-variable problems. The BracketMath optimiser does the joint problem: every (salary, pension) cell evaluated through the full tax stack, accounting for the four-band salary problem, the £100k taper, the CT marginal-relief band, and the Annual Allowance taper simultaneously. The improvement is typically £2k–£35k/yr at typical income levels.

What happens to my pension at age 55 / 57?

From age 55 (rising to 57 from 6 April 2028 per the Finance Act 2021) you can access defined-contribution pensions. The first 25% of the pot is tax-free (the "Pension Commencement Lump Sum"), subject to the £268,275 Lump Sum Allowance. The remainder is drawable at your marginal income-tax rate — but you can phase it across decumulation years to keep most of it within the 20% basic-rate band.

How much can I put into pension this year?

The 2026/27 pension Annual Allowance is £60,000. Below £260,000 of adjusted income the full £60,000 Annual Allowance is available. Carry-forward of unused AA from the last three tax years is available subject to membership-in-each-year rules.

Is the Employment Allowance available for a single-director company?

No. A company with only one director who is also the sole paid employee cannot claim the £10,500 Employment Allowance (HMRC manual ESM4017). For genuine multi-employee setups it is claimable and the optimiser can model it via the `claimEmploymentAllowance` flag.

Why does the optimiser want such a large pension contribution?

Because employer pension contributions dodge three taxes simultaneously: corporation tax (deductible), employer NI (none), and personal income tax / NI / dividend tax (none until drawdown). For this row the optimiser allocates £60,000 to pension — the largest tax shelter available to a director.
