Step by step: how the engine arrived at the bottom line

The joint optimiser ran a grid search over (salary, pension) — salary in £100 steps from £0 to £60,000, pension in £500 steps from £0 to the £60,000 Annual Allowance — and evaluated each combination through the full tax stack. Here is the step-by-step trace that produced the optimum for a accountant at £150,000 of company profit:

Salary chosen: £12,570. Sits between the £12,570 PA and the £50,270 higher-rate threshold (paying basic-rate income tax + main-band employee NI).
Employer NI on salary: £1,136 (15% above the £5,000 Secondary Threshold).
Pension chosen: £60,000 as an employer contribution — CT-deductible, no NI either side, no income tax until drawdown.
Pre-CT profit: £76,295 = company profit minus salary, minus employer NI, minus pension contribution.
Corporation tax: £16,468 (regime: marginal).
Dividend extraction: all post-CT profit paid out — £59,826.
Personal taxes: employee NI £0 on salary; income tax £0 on salary; dividend tax £10,723 on the dividend (after the £500 Dividend Allowance and stacked above salary in the band schedule).
Net cash: £61,674. Net wealth (cash + pension): £121,674.

Why this scenario is different

Compared to the closest peer profile — IT contractor at £150,000 — 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

Does it include Scottish income tax?

No. Scotland has its own income-tax band schedule (Starter 19% / Basic 20% / Intermediate 21% / Higher 42% / Advanced 45% / Top 48% for 2026/27). National Insurance and corporation tax are still set at UK-wide rates. A Scotland-specific batch of programmatic pages is planned but is not in this batch.

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.

Is the State Pension worth deferring?

For State Pensions claimed after 6 April 2016, deferring uplifts the entitlement by 1% for every 9 weeks deferred (about 5.8% per year). The break-even is approximately 17 years — if you expect to live materially longer than 17 years after State Pension Age, deferring marginally wins. Most people claim on time and invest the cash instead.

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.

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.
