Worked example: Handyman, 48, £40,000 of turnover

Picture a handyman aged 48 for the 2026/27 tax year, trading as a sole trader with £40,000 of turnover. The optimisation goal for this profile is a balance of cash and pension contribution (modest pension preference, treating £1 of pension as £0.50 of cash for the search).

Running the engine for this exact profile:

Taxable profits after the trading-allowance choice: £38,000
Income tax: £5,086
Class 4 NI: £1,526
Class 2 (voluntary): £179
Net cash: £31,209 (17% effective on turnover)
Same turnover as a Ltd Co (no pension): £30,570 — a gap of £638 in favour of staying a sole trader

The vignette is hypothetical but the numbers are not — every figure above was produced by the same engine code that powers the live BracketMath calculators, run at build time on inputs drawn from a single CSV row.

The numbers, line by line

Gross income	£40,000
Net cash	£31,209
Pension contribution	£0
Total deductions	£6,791
Effective rate	17%
Marginal rate	26%
Years to age-57 pension access	9
Annual pension contribution (this row)	£0
Projected pot at 57 (5% real, single-path)	£0
Sustainable income @ 4% SWR	£0/yr

Why this scenario is different

Compared to the closest peer profile — Freelance designer at £40,000 — 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. Taxable profits change from £38,000 to £38,000 (after the trading-allowance / actual-expenses choice).

Questions this scenario raises

When does the £50,270 higher-rate threshold start to bite a sole trader?

Once total taxable income (trading profits + other income, after the Personal Allowance) exceeds £37,700. At that point, each £1 of additional trading profit is taxed at 40% income tax + 2% Class 4 NI = 42% combined marginal. This is also the point at which "should I incorporate?" tends to start producing a meaningful answer.

What does the "marginal rate" mean on this page?

It is the rate paid on the next £1 of gross income added to this scenario. For this row that figure is 26.0%. The marginal rate is always higher than the average effective rate — it is the right number for "is one more invoice worth it" decisions.

Is the figure on this page net of accountancy fees?

Yes when relevant — the take-home calculator deducts an umbrella fee for inside-IR35 rows (£1,500/yr assumed) and the optimiser allows for an arbitrary annual business expense pot (£3,500/yr default for Ltd Co rows). Sole-trader rows assume the higher of £800/yr or 5% of turnover as actual business expenses, which approximates a low-overhead service business.

Why does the page link to specific other professions?

The five linked pages at the bottom are computed by a similarity metric over (profession, income, structure, age band) — the closest five neighbours in that space, not the same five pages every row links to. The aim is a genuine cross-link graph rather than a star pattern that search engines correctly read as a pSEO signal.

How many qualifying years do I need for the full new State Pension?

35 qualifying years for the full new State Pension. With fewer, the pension is pro-rated (1/35 per year). A minimum of 10 qualifying years is required for any new State Pension. Voluntary Class 2 (sole traders) or Class 3 (everyone else) can plug gaps in the NI record.

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.
