At £700/day, the contractor tax picture reverses: umbrella and PAYE produce more monthly take-home cash than a standard Ltd company. But the headline figures are misleading. The Ltd company retains £17,731/year inside the company — wealth that accumulates with significant long-term value when channelled into a company pension.
Take-Home Comparison — £700/Day

| Annual take-home | £79,630 | £82,415 | £83,106 |

At £700/day, umbrella/PAYE produce £232–£290/month more in personal cash. But Ltd retains £1,478/month inside the company.
Ltd Company Calculation (Outside IR35, income capped at £99,500)
Annual revenue: £154,000
- Director salary: −£12,570
- Employer NI: −£1,136
- Ltd expenses: −£3,000
- Taxable profit: £137,294
Corporation tax (marginal relief): CT = 25% × £137,294 − (£250,000 − £137,294) × 3/200 = £34,324 − £1,691 = £32,633 (effective rate: ~23.8%)
Profit after CT: £104,661
Dividends paid (to keep personal income at £99,500): £86,930
- Retained in company: £17,731
Dividend tax (same as £600/day — same personal income):
- £500 at 0% = £0
- £37,200 at 8.75% = £3,255
- £49,230 at 33.75% = £16,615
- Total dividend tax: £19,870
Take-home: £12,570 + £86,930 − £19,870 = £79,630/year = £6,636/month
Umbrella Company Calculation (Inside IR35 — PA fully tapered)

The £17,731 Retained Profit — The Real Ltd Advantage
At £700/day, the Ltd company is not primarily about monthly take-home — it’s about wealth accumulation inside the company. £17,731/year stays in the company. Options:
Option A — Company pension: Contributed as a company pension, the £17,731 costs approximately £10,200 in effective foregone take-home (after CT relief on the contribution). You accumulate £17,731 of pension wealth at a net cost of £10,200. This is the highest-returning use.
Option B — Invest inside the company: The retained profit can be invested in funds, gilts, or bonds inside the company. Investment income is subject to CT, but the compounding over 10+ years is substantial.
Option C — Draw in low-income years: If a £700/day contractor takes 6 months off, the accumulated retained profit can be drawn as dividends in a year with minimal other income — at basic rate dividend tax (8.75%) instead of higher rate (33.75%).
5-year value of retained profit (illustrative):
| Strategy | 5-year accumulated value | Effective net cost |
|---|---|---|
| Pension contributions | £88,655 pension pot | ~£51,000 |
| Company investment | ~£80,000 (after CT on returns) | — |
| Lump withdrawal in gap year | £88,655, taxed at ~8.75% | — |
Pension Strategy at £700/Day — Maximum Efficiency
With £17,731/year already retained plus the existing personal income structure, the optimal approach:
- Direct all retained profit to pension — £17,731/year company contribution, CT relief means net cost ~£13,572 (after 23.8% CT saving)
- Add additional pension from current year profit to push total pension to annual allowance cap (£60,000)
- Result: personal take-home maintained at £6,636/month while building substantial pension pot
| Annual pension | Monthly take-home | Annual pension accumulation | 5-year pot |
|---|---|---|---|
| £17,731 (retained profit only) | £6,636 | £17,731 | £88,655 |
| £35,000 | £5,941 | £35,000 | £175,000 |
| £55,000 | £4,980 | £55,000 | £275,000 |
