How HMRC defines the band this income falls into

A freelance developer at £50,000 of gross for 2026/27 — plus any other personal income that stacks below — falls into the basic-rate band. HMRC's published rules for this band are unchanged from the figures announced in the Autumn Budget 2024 (which froze all the major thresholds at their April 2021 levels until at least April 2028).

For reference, the 2026/27 boundary numbers as published by HMRC:

Personal Allowance: £12,570 (full PA — tapered above £100,000 adjusted net income).
Basic-rate band: £12,570 to £50,270 (20% income tax, 8.75% dividend tax).
Higher-rate band: £50,270 to £125,140 (40% / 33.75%).
Additional-rate band: above £125,140 (45% / 39.35%).
PA taper: £1 of PA lost per £2 over £100,000 adjusted net income, fully eroded at £125,140.
Employer NI: 15% above the £5,000 Secondary Threshold (Finance Act 2024).
Employee NI: 8% main band (£12,570–£50,270), 2% above.
Class 4 NI (sole traders): 6% main band, 2% above. Class 2 voluntary: £3.45/week (£179.40/yr).
Corporation Tax: 19% small profits rate (≤ £50,000), 25% main rate (≥ £250,000), 26.5% effective marginal in between.
Dividend Allowance: £500 at 0%.
Pension Annual Allowance: £60,000 (tapered to £10,000 above £260,000 adjusted income).

For this specific row, the binding constraints are: the sole-trader Class 4 NI bands (6% / 2%) and the 20% basic-rate band.

The engine's computed bottom line for this row, given those binding constraints: net cash £38,239, pension £0, effective rate 18.5%, marginal rate 26%.

Why this scenario is different

Compared to the closest peer profile — Electrician at £50,000 — 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 £47,500 to £47,500 (after the trading-allowance / actual-expenses choice).

Questions this scenario raises

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).

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.

What tax year do these figures use?

2026/27 UK tax year (6 April 2026 – 5 April 2027), England, Wales and Northern Ireland rates. Scottish tax bands are not modelled in this calculation — Scotland has a separate Starter / Basic / Intermediate / Higher / Advanced / Top band schedule that will be added in a future batch.

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.
