The decision tree for a freelance writer at this income level

A freelance writer 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 £30,000 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 sole-trader 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: £0.
What is the resulting net cash? £24,179. Net wealth including pension: £24,179.

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.

Why this scenario is different

Compared to the closest peer profile — Driving instructor at £30,000 — 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 £28,500 to £28,500 (after the trading-allowance / actual-expenses choice).

Questions this scenario raises

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.

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.

How does the Pension Annual Allowance taper work?

Above £260,000 of adjusted income, the £60,000 Annual Allowance reduces by £1 for every £2 over the threshold, down to a £10,000 floor at £360,000 of adjusted income. The taper bites later than the £100k Personal Allowance taper but is similarly punitive on pension contributions specifically.

Where does the BracketMath engine source its rates?

Income tax / NI / CT / dividend rates come from HMRC's published 2026/27 rate tables (gov.uk/government/publications/rates-and-allowances-income-tax). Pension rules come from FA 2004 and the FCA's consumer guidance. Historical investment returns used in the Monte Carlo engine come from a 125-year UK gilt + UK equity series stored in src/data/historical-returns.json. Every constant carries a source URL in the source code.

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).

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.
