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

For a sole-trader nurse with £35,000 of turnover, the engine evaluated each stage of the Self Assessment chain in HMRC's order:

  1. Turnover: £35,000.
  2. Expense vs trading-allowance decision: the £1,000 trading allowance (ITTOIA 2005 s.783A) lost to actual expenses and was discarded.
  3. Taxable profits: £33,250.
  4. Income tax: £6,126 (rUK bands, after Personal Allowance).
  5. Class 4 NI: £1,241 (6% £12,570–£50,270, 2% above).
  6. Class 2 (voluntary): £179 — £179.40/yr, paid to maintain a State Pension qualifying year per HMRC's voluntary NI guidance.
  7. Net cash: £25,704. Effective rate on turnover: 21.6%.

Why this scenario is different

Compared to the closest peer profile — Freelance developer at £35,000 — this scenario sits £0 higher on gross income. That moves net cash by −£1,990, the pension contribution by +£0, and the effective rate by +5.7%. The shift in effective rate is large enough that the binding tax constraint has changed — probably crossing a band boundary. Taxable profits change from £33,250 to £33,250 (after the trading-allowance / actual-expenses choice).

Questions this scenario raises

How does my PAYE day job interact with this side-hustle income?

For this row there is £25,000 of other personal income stacking below the self-employment figure. The PAYE / other income uses the Personal Allowance first, then the basic-rate band, then the higher-rate band — the self-employment income is "stacked" on top and taxed at whichever marginal rate it lands in. That is why low self-employment income can still attract 40% tax if the PAYE income is large enough to push the marginal slice into higher rate.

What expenses can I deduct as a sole trader?

"Wholly and exclusively" business costs — equipment, software, professional insurance, travel to non-permanent workplaces, training that maintains existing skills, a proportionate share of home-office costs (HMRC simplified flat rates available), and accountancy fees. Personal commuting, entertainment, training to acquire new skills, and clothing (unless protective / uniform) are not deductible.

How much can I put into pension this year?

The 2026/27 pension Annual Allowance is £60,000. Below £260,000 of adjusted income the full £60,000 Annual Allowance is available. Carry-forward of unused AA from the last three tax years is available subject to membership-in-each-year rules.

How do I avoid the 60% taper?

For a salaried employee: salary sacrifice into pension. For a Ltd Co director: employer pension contribution. For a sole trader: personal pension contributions (which reduce adjusted net income). The taper-zone marginal of 60% means each £1 of pension contribution effectively costs the saver 40p of foregone cash — the strongest tax shelter the UK code currently offers.

Does this calculation include student loan repayments?

No. Student Loan repayments (Plan 1 / 2 / 4 / 5 / Postgraduate) are not modelled in the BracketMath engines. Plan 2 repayments at 9% above £27,295 add roughly 9p of marginal cost to each £1 of taxable income above the threshold. Add this to the marginal rate quoted on this page if you have an outstanding student loan.

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.
