At £300/day (220 days, £66,000/year), the Ltd vs umbrella gap reaches its widest point in the lower range: £419/month (£5,028/year). This is partly because the company profit of £49,294 still attracts 19% corporation tax — just under the £50,000 small profits threshold — while umbrella income at this rate crosses into 40% higher rate income tax.

- Director salary: −£12,570
- Employer NI: −£1,136
- Ltd expenses: −£3,000
- Taxable profit: £49,294 (just under £50,000 small profits limit)
Corporation tax (19%): £9,366 Profit after CT: £39,928
Dividends:
- £500 at 0% = £0
- £37,200 (remaining basic rate room) at 8.75% = £3,255
- £2,228 (above £50,270 total income) at 33.75% = £752
- Total dividend tax: £4,007
Take-home: £12,570 + £39,928 − £4,007 = £48,491/year = £4,041/month
Umbrella Company Calculation (Inside IR35)
Revenue after umbrella margin: £64,500 Gross salary: (£64,500 + £750) ÷ 1.15 = £56,739
Umbrella crosses the higher rate threshold:
| Earnings | Rate | Tax |
|---|---|---|
| £12,571–£50,270 | 20% | £7,540 |
| £50,271–£56,739 | 40% | £2,588 |
| Total income tax | £10,128 |
Employee NI: (£37,700 × 8%) + (£6,469 × 2%) = £3,016 + £129 = £3,145
Take-home: £56,739 − £10,128 − £3,145 = £43,466/year = £3,622/month
PAYE Calculation
Gross salary: (£66,000 + £750) ÷ 1.15 = £58,043
- Income tax: £10,649 (£7,540 basic + £3,109 higher rate)
- Employee NI: £3,171
- Take-home: £44,223/year = £3,685/month
Why This Rate Has the Biggest Ltd Advantage
At £300/day, a unique combination makes Ltd maximally efficient:
- Company profit (£49,294) stays at 19% CT — just under the small profits threshold
- Umbrella income (£56,739) crosses into 40% higher rate — the worst position for PAYE
- Dividend higher rate exposure is minimal — only £2,228 of dividends taxed at 33.75%
Above £300/day, company profits cross £50,000 and attract marginal CT rates, slowly eroding the advantage. But the Ltd route remains significantly better up to £500/day.
Pension Strategy at £300/Day
With £39,928 in post-CT profit available for dividends, a £5,000 company pension contribution (paid directly from the company) would:
- Reduce taxable profit to £44,294 → CT saving at 19%: £950
- Completely eliminate the higher rate dividend exposure (personal income drops to £47,000)
- Net pension cost to company: ~£4,050 (after CT saving)
A £5,000/year company pension contribution costs effectively £4,050 and eliminates all higher rate tax exposure. At £300/day, pension contributions are highly efficient.
Worked Example — Helen, Senior Business Analyst
Helen contracts at £300/day as a senior business analyst in financial services, outside IR35. Annual revenue: £66,000.
Annual company accounts:
- Revenue: £66,000
- Salary + employer NI: £13,706
- Expenses: £3,000
- Company pension contribution: £5,000
- Profit: £44,294
- CT (19%): £8,416
- Available for dividends: £35,878
Helen’s income:
- Salary: £12,570
- Dividends: £35,878 (all in basic rate band → tax: £3,098)
- Monthly take-home: £3,779 (including pension benefit)
- Company pension pot: growing by £5,000/year
Without the pension, she’d take home £4,041/month but pay £752 in higher rate dividend tax. With the pension, she takes home slightly less personally but contributes £5,000/year to retirement at an effective cost of £4,050.
