| Dividend tax | -£15,153 | — | — |
| Take-home | £67,287 | £61,253 | £60,753 |
For umbrella and inside-IR35 figures, employer NI is deducted from the gross fee before income is taxed — this is the primary reason why take-home is so much lower than the gross rate suggests.
At £450/day, running a limited company outside IR35 saves you £6,034/year over umbrella. After accounting for accountancy fees (£1,500–£2,500/year) and PI insurance (~£300), the net advantage is approximately £3,200–£4,200/year.
Why £450/day is where pension planning starts to matter
At £450/day, your total income (salary + dividends) is approximately £79,863 — approaching the point where marginal rate planning becomes important. While this is below the £100,000 personal allowance taper threshold, it is firmly in higher-rate dividend territory.
Of your ~£67,000 in dividends, roughly:
- £37,200 is taxed at 10.75% (basic rate band) = £3,999
- ~£30,100 is taxed at 35.75% (higher rate band) = £10,761
- Total dividend tax: ~£14,760
Every £1,000 you contribute to your pension instead of taking as higher-rate dividends saves approximately £509 in combined Corporation Tax and dividend tax. A £10,000 pension contribution effectively costs you just £4,910 in forgone take-home — and puts £10,000 into your pension.

How does this compare to permanent employment?
A £450/day rate sounds like £104,400 per year — but the equivalent permanent salary is considerably lower once you account for what employers provide to permanent staff:
| Benefit | Permanent value | Contractor equivalent |
|---|---|---|
| Employer pension (5% of £80k salary) | £4,000/year | You fund yourself |
| 25 days holiday pay | ~£8,654 (£450 × 19.2 days at billing rate) | Unpaid — you bear the cost |
| Sick pay | £750–£2,000 | Not available |
| Employer NI saving | £10,457 | Not applicable |
Adding these back, the equivalent permanent salary for a £450/day contractor is roughly £78,000–£82,000. On a £80,000 permanent salary, take-home after income tax and NI is approximately £55,600 — £11,687 less than the £67,287 you’d keep contracting outside IR35. That gap is meaningful, but narrower than many contractors expect.
Year-on-year comparison
| Tax year | Ltd (outside IR35) | Change |
|---|---|---|
| 2025/26 | £68,686 | — |
| 2026/27 | £67,287 | -£1,399/year |
The £1,399 reduction is driven by the 2pp dividend tax increase from April 2026 (basic rate 8.75% → 10.75%, higher rate 33.75% → 35.75%). With roughly half of dividends in the basic rate band and half in the higher rate band at this income level, the two-percentage-point rise costs approximately £700 on each tranche.

What if you’re inside IR35?
At £450/day inside IR35, your take-home is £60,753 — a gap of £6,534/year versus outside IR35. The difference is primarily:
- Employer NI on your full fee: your fee payer deducts 15% employer NI on earnings above £5,000 before calculating your taxable income. At £450/day, that’s roughly £14,310.
- Loss of dividend tax efficiency: all income is taxed as employment income (20–40% income tax + 8% employee NI) rather than the lower dividend rates.
- No Corporation Tax deduction: there’s no company profit to optimise.
To match your £67,287 outside-IR35 take-home inside IR35, you’d need to charge approximately £575/day — a £125/day (28%) premium. Negotiate accordingly before accepting an inside-IR35 contract. Check your IR35 status →
