The £100,000 cliff catches almost every higher-earning contractor

Before the numbers, a warning: a sap consultant at £180,000 of company profit for 2026/27 is sitting close to one of the UK tax code's sharpest cliffs.

This row sits above the £125,140 boundary at which the Personal Allowance is fully eroded. The taper trap is behind you, but the additional-rate threshold (45% income tax / 39.35% dividend tax) is now in play. The next £1 of dividend is taxed at the additional-rate dividend rate of 39.35% — which makes pension contributions (still 0% at the company-contribution level) disproportionately valuable, subject to the £60,000 Annual Allowance and its £260,000 tapered version.

The numbers for this specific scenario

Bottom line for a sap consultant at £180,000 of gross income: net cash £76,282; pension £60,000; effective rate on gross 24.3%.

The numbers, line by line

Optimum salary	£12,570
Optimum dividend	£81,876
Optimum pension	£60,000
Net cash (optimum)	£76,282
Net wealth (cash + pension)	£136,282
Rule-of-thumb net cash	£102,233
Rule-of-thumb net wealth	£102,233
Saving vs rule of thumb	£34,049
Effective rate on profit	24.3%
Marginal rate (next £1 dividend)	33.8%

Why this scenario is different

Compared to the closest peer profile — Software contractor at £180,000 — 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

Is the Employment Allowance available for a single-director company?

No. A company with only one director who is also the sole paid employee cannot claim the £10,500 Employment Allowance (HMRC manual ESM4017). For genuine multi-employee setups it is claimable and the optimiser can model it via the `claimEmploymentAllowance` flag.

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.

Is this calculation valid for the 2027/28 tax year?

Only partially. Thresholds (PA, basic-rate, higher-rate, NI thresholds) are frozen through April 2028 per the Autumn Budget 2024. Some rates may change at the Spring 2027 Budget. The figures here are accurate for 2026/27 and will be re-run after any future Finance Act changes — check the published-date footer of this page.

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.

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.

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.
