The decision tree for a test engineer contractor at this income level

A test engineer contractor thinking through "how should I structure this income for tax efficiency" hits the same five branches every time. Walk the tree for this exact scenario (gross £95,000 for 2026/27):

Is the engagement inside or outside IR35? Inside (umbrella) means no dividend extraction, no employer pension dodge, full PAYE deduction. Outside (Ltd Co) means access to the optimiser. This row models the outside-IR35 Ltd Co route.
Are you using the £12,570 Personal Allowance? Yes — fully. No other personal income is in play, so all £12,570 of PA is available to absorb the cheapest slice of structure-specific income.
Are you above the £100,000 PA taper? No — gross sits comfortably below the £100,000 trigger.
How heavily are you using the pension wrapper? Moderately — the search treats £1 of pension as worth £0.50 of cash today, producing a balanced cash / pension split. The pension contribution chosen by the engine for this row: £31,000.
What is the resulting net cash? £49,013. Net wealth including pension: £80,013.

For the second-order question — what would happen at a different profit level, a different age, or a different pension preference — the same engine drives the salary-dividend split calculator, the take-home (inside vs outside IR35) calculator, and the SIPP optimiser. Each one accepts the inputs of this row as a starting point.

The numbers, line by line

Optimum salary	£12,570
Optimum dividend	£40,716
Optimum pension	£31,000
Net cash (optimum)	£49,013
Net wealth (cash + pension)	£80,013
Rule-of-thumb net cash	£64,108
Rule-of-thumb net wealth	£64,108
Saving vs rule of thumb	£405
Effective rate on profit	15.8%
Marginal rate (next £1 dividend)	33.8%

Why this scenario is different

Compared to the closest peer profile — IT contractor at £95,000 — 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

Should I take the £12,570 standard director salary?

For this row the optimiser settled on a salary very close to the £12,570 standard — confirming the rule of thumb works here.

Why does the optimiser pay a salary above £5,000 if employer NI starts there?

Because beyond the £5,000 Secondary Threshold, each £1 of salary still saves 19–25% of corporation tax and only costs 15% in employer NI plus 8% employee NI — a net 11–17% saving up to the £12,570 Personal Allowance. The 2026/27 optimum for this row is £12,570 of salary, sitting in exactly this regime.

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.

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 33.8%. The marginal rate is always higher than the average effective rate — it is the right number for "is one more invoice worth it" decisions.

What is the Personal Allowance and how is it used in this calculation?

The Personal Allowance is the first £12,570 of non-savings, non-dividend income on which no income tax is charged. It is consumed from the bottom up: salary first, then dividends. Above £100,000 of adjusted net income the allowance tapers at £1 lost for every £2 of income, fully eroded at £125,140 — producing the well-known 60% effective marginal rate inside that £25,140-wide band.

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.
