What the popular advice gets wrong at this income

Every accountancy thread, IR35 forum and contractor podcast has its own simple rule for handling a agile coach contractor at this income level. The popular rules are:

  1. "Just take a £12,570 salary and dividend the rest" — works between roughly £40k and £80k of profit; breaks down above the £100,000 PA-taper cliff and around the £50k–£250k corporation-tax marginal-relief band.
  2. "60% goes to the tax man on anything over £100k" — true within the £25,140-wide taper band, but it is the marginal rate, not the average. Most contractors hear "60%" and assume their whole income is being taxed at that rate, which is wrong.
  3. "Pension contributions don't help if you only have a Ltd Co" — wrong. Employer pension contributions are deductible against corporation tax, attract no NI either side, and are not personal income — making them the single most powerful lever in the high-rate / taper bands.
  4. "The optimal salary is exactly the secondary threshold" — historically true; in 2026/27 the secondary threshold (£5,000) is so low that ignoring the £5k–£12,570 region is leaving free Personal Allowance on the table.

For a agile coach contractor at £130,000 of gross, the BracketMath optimiser disagrees with at least one of those rules — that's why we built it.

Specifically, the joint optimum at this profit level is £12,570 of salary, £45,126 of dividend, £60,000 of employer pension contribution. The rule-of-thumb baseline (£12,570 salary, no pension, max dividend) produces only £80,972 of net wealth — a shortfall of £30,963 versus the joint optimum.

The numbers, line by line

Optimum salary £12,570
Optimum dividend £45,126
Optimum pension £60,000
Net cash (optimum) £51,935
Net wealth (cash + pension) £111,935
Rule-of-thumb net cash £80,972
Rule-of-thumb net wealth £80,972
Saving vs rule of thumb £30,963
Effective rate on profit 13.9%
Marginal rate (next £1 dividend) 33.8%

Why this scenario is different

Compared to the closest peer profile — IT contractor at £130,000 — 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

Are dividends "double taxed" because corporation tax was already paid?

Yes — but the dividend tax rates (8.75% / 33.75% / 39.35%) are set lower than the equivalent income-tax rates (20% / 40% / 45%) precisely to account for the corporation tax already paid at company level. The combined CT + dividend tax stack is usually still cheaper than the salary stack of income tax + employer NI + employee NI for any single £1, which is why the optimiser puts most extraction through dividends.

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.

Should I take dividends now or wait until next tax year?

Tax-year-end timing matters: a dividend declared in March 2027 is taxed at 2026/27 rates; one declared in April 2027 falls into 2027/28 (potentially still in the same calendar year). If your 2026/27 personal income is bunched in basic-rate territory and 2027/28 will be in higher-rate, accelerate. If the reverse, defer. The mathematical structure is "level the tax-band utilisation across years if income is volatile."

Are the engine assumptions documented anywhere?

Yes — every constant lives in src/lib/tax/constants.ts with a source-URL comment. Every engine function is unit-tested against HMRC examples (180+ test cases). The full methodology is at /about and the per-engine assumptions are spelled out at the foot of each calculator.

How is corporation tax calculated in this scenario?

The taxable post-pay profit falls in the £50,000–£250,000 "marginal-relief band". Corporation tax is computed as 25% of taxable profits minus marginal relief, producing an effective marginal rate of 26.5% on each pound between the two thresholds.

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.
