What a cloud architect contractor on £160,000 of company profit actually takes home

A cloud architect contractor running a personal Ltd Co with £160,000 of profit before director pay (2026/27 rUK rates) can extract that profit as some mix of salary, dividend and employer pension. The joint optimum — the combination that produces the highest net wealth — pays £12,570 as salary, £67,176 as dividend and £60,000 as an employer pension contribution. Total tax + NI through the chain comes to £33,457 — an effective rate of 20.9% on company profit.

The "rule of thumb" baseline — £12,570 salary, no pension, max dividend — leaves £33,168 on the table at this profit level. That gap is the value of solving the four-band salary problem (LEL / PT / ST / £12,570) jointly with the pension decision rather than picking each one independently.

The five tax lines that produce the optimum

  • Corporation tax: £19,118 on £86,295 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: £13,203 on the £67,176 dividend (8.75% / 33.75% / 39.35% bands, stacked above salary).

Net cash to the director: £66,543. Pension contribution (locked until age 55, rising to 57 from 6 April 2028 per the Finance Act 2021): £60,000. Net wealth on the all-£1-is-equal view: £126,543.

Why this scenario is different

Compared to the closest peer profile — Software contractor at £160,000 — 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 do some columns of the table use cash and others use net wealth?

Net cash is the £ that arrive in your bank account. Net wealth includes pension contributions valued at face (£1 of pension = £1 of wealth, since it will eventually be spent — possibly at a lower marginal rate than today). The optimiser uses a `pensionWeight` parameter so the user can adjust the weight; this page sets it according to the row's `pensionPref` (0 / 0.5 / 1.0 for none / modest / aggressive).

Why is the effective rate lower than the headline tax brackets?

Because the headline 20% / 40% / 45% rates apply only to the income slice in each band — not the whole income. The Personal Allowance shelters the first £12,570 at 0%; the basic-rate band only charges 20% on the next £37,700; and so on. The effective rate on the entire income is the weighted average of every slice — typically much lower than the headline number people quote.

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 if I have rental income alongside this self-employment?

Add it to the `otherIncome` field of the calculator. Property income is taxed at non-savings, non-dividend rates (so stacks alongside salary in the band schedule). The first £1,000 of rental income can also be sheltered by the separate Property Allowance under FA 2017 s.16.

How do I model my partner's income alongside mine?

BracketMath models a single tax entity — there is no joint-couple calculation. For couples, the practical approach is to run each partner separately and consider income-splitting strategies (employing the lower-earning spouse for genuine work performed, sharing dividends if both are shareholders, etc). The Ltd Co spousal share pattern is sketched in /guides/ltd-company-director-tax.

Methodology

Income tax, National Insurance and Corporation Tax bands taken from HMRC's 2026/27 rates and allowances tables (gov.uk/.../income-tax; corporation-tax). Pension Annual Allowance and taper rules from Finance Act 2004 / 2023. Trading allowance per ITTOIA 2005 s.783A. Voluntary Class 2 figure (£179.40/yr = £3.45/wk × 52) from HMRC voluntary NI guidance.

Style: 2026/27 tax year throughout; figures rounded to whole pounds in the user-facing prose; effective rates computed as (deductions / gross). The voice is methodological — no first person, no claimed credentials, no marketing fluff.
