Every UK contractor faces this question at some point: is the Limited Company worth the admin overhead, or does the umbrella company work out to be nearly as good? The answer depends entirely on your day rate, your IR35 status, and your personal circumstances. This guide does not give a generic answer — it gives real numbers at three day rates, post-April-2026, so you can see the actual difference.
The two structures explained
Umbrella company (Inside IR35 PAYE): You are employed by the umbrella company. The umbrella bills the agency or client at your assignment rate, deducts its margin and employer-side costs (employer NI at 15%, apprenticeship levy at 0.5%), then processes the remainder through PAYE. You receive a net salary after income tax and employee NI. You have no company to maintain, no corporation tax to file, and no accountant to pay. You are, for all intents and purposes, a temporary employee.
Limited Company (Outside IR35): You run your own company. The company invoices the client or agency, pays corporation tax on its profits, and you draw a small director salary plus dividends. You have more control over your tax position through pension contributions, salary optimisation, and retained profit. You also have ongoing compliance obligations: payroll, annual accounts, corporation tax return, confirmation statement, VAT (if registered). Accountancy typically costs £1,000–£1,500/yr.
The fundamental question is whether the tax efficiency of the Limited Company structure outweighs the hidden costs and compliance burden.
The umbrella supply chain: what the margin covers
When a client agrees to pay £500/day for your services through an agency, the assignment rate is £500/day. By the time you receive your pay, several deductions have been made:
- Umbrella margin: typically £15–£30/week (around £750–£1,500/yr). This is the umbrella's fee for employment administration.
- Employer NI at 15% on your deemed salary above the secondary threshold (£5,000). On a £115K gross, this is approximately £16,500.
- Apprenticeship levy at 0.5% on total pay above £3,000. On £115K this is approximately £560.
- Holiday pay is sometimes included in the assignment rate rather than paid separately — check your contract carefully.
After these employer-side deductions, income tax and employee NI are calculated on what remains. This is why umbrella take-home is structurally lower than it looks — the employer NI comes from the same assignment rate that you'd otherwise invoice.
Worked examples at three day rates
All figures are 2026/27 rates: dividend tax basic 10.75%, higher 35.75%; corporation tax 25% main rate (marginal relief below £250K); income tax 20%/40%/45%; employee NI 8%/2%; employer NI 15% (secondary threshold £5,000); umbrella margin assumed £1,200/yr; Ltd accountancy £1,200/yr; 250 working days per year.
£400/day — £92,000 gross (46 weeks × 5 days × £400)
Outside IR35 Limited Company:
- Company receipts: £92,000
- Director salary: £12,570; employer NI on salary: (£12,570 − £5,000) × 15% = £1,136; accountancy: £1,200
- Taxable profit: £92,000 − £12,570 − £1,136 − £1,200 = £77,094
- Corporation tax at 25%: £19,274
- Dividend available: £77,094 − £19,274 = £57,820
- Director salary net (no income tax, no employee NI under £12,570): £12,570
- Dividend tax: £500 allowance free; £37,700 at 10.75% = £4,053; remaining £19,620 at 35.75% = £7,014; total dividend tax = £11,067
- Ltd net annual take-home: approximately £59,300
Inside IR35 Umbrella:
- Assignment rate: £92,000
- Employer NI: (£92,000 − £5,000) × 15% = £13,050
- Apprenticeship levy: (£92,000 − £3,000) × 0.5% = £445
- Umbrella margin: £1,200
- Net salary subject to PAYE: £92,000 − £13,050 − £445 − £1,200 = £77,305
- Personal allowance: £12,570; taxable income: £64,735
- Income tax: £37,700 × 20% = £7,540; £27,035 × 40% = £10,814; total = £18,354
- Employee NI: (£50,270 − £12,570) × 8% = £3,016; (£77,305 − £50,270) × 2% = £541; total = £3,557
- Umbrella net annual take-home: approximately £55,400
Gap at £400/day: approximately £3,900
£500/day — £115,000 gross (46 weeks × 5 days × £500)
Outside IR35 Limited Company:
- Company receipts: £115,000
- Director salary: £12,570; employer NI: £1,136; accountancy: £1,200
- Taxable profit: £115,000 − £12,570 − £1,136 − £1,200 = £100,094
- Corporation tax at 25%: £25,024
- Dividend available: £100,094 − £25,024 = £75,070
- Dividend tax: £500 free; £37,700 at 10.75% = £4,053; £36,870 at 35.75% = £13,181; total = £17,234
- Director salary net: £12,570
- Ltd net annual take-home: approximately £70,400
Note: at this income level the personal allowance begins to taper (income above £100K reduces PA by £1 for every £2 over). The director's adjusted net income (salary + dividends above PA) should be checked — employer pension contributions are the most effective way to bring income below £100K.
Inside IR35 Umbrella:

- Employer NI: (£115,000 − £5,000) × 15% = £16,500

- Umbrella margin: £1,200
- Net salary subject to PAYE: £115,000 − £16,500 − £560 − £1,200 = £96,740
- Personal allowance: £12,570; taxable income: £84,170
- Income tax: £37,700 × 20% = £7,540; £46,470 × 40% = £18,588; total = £26,128

Gap at £500/day: approximately £3,700
£700/day — £161,000 gross (46 weeks × 5 days × £700)
Outside IR35 Limited Company:

- Corporation tax at 25%: £36,524
- Dividend available: £146,094 − £36,524 = £109,570
- Personal allowance is fully tapered at this income (above £125,140 total income means £0 PA applies to dividend — director salary uses its own portion separately). Adjusted net income above £125,140 means full PA loss on dividends.

The hidden costs of the Limited Company
The figures above include £1,200/yr accountancy but do not capture every real cost of running a Limited Company:
- Accountancy and payroll: £1,000–£1,500/yr for a basic contractor accountancy package. This is included in the figures above at £1,200.
- Time: Filing confirmation statements, reviewing accounts, liaising with your accountant, managing payroll. Estimate 8–15 hours/yr even with a good accountant.
- IR35 risk: If HMRC or a client later determines you were Inside IR35 while operating as Outside, the exposure can be significant — back taxes, interest, and penalties. Umbrella eliminates this risk entirely.
- Professional indemnity insurance: More relevant for Ltd than umbrella arrangements.
- Compliance risk: Missing filing deadlines triggers automatic penalties (£150 for late accounts, £100 for late confirmation statement, and escalating penalties for late corporation tax returns).
If you value your time at £50–£100/hr, the 10–15 hours of annual administration cost represents an additional £500–£1,500 of implicit cost — not shown in take-home calculations.
When umbrella makes sense despite being less efficient
Umbrella is the right choice — or the only realistic choice — in several scenarios:
You are determined to be Inside IR35. If the client has issued an SDS (Status Determination Statement) placing you Inside IR35, the Limited Company structure provides no advantage on that contract. You'll pay PAYE either way; the umbrella is simpler.
Short-term contracts. For a 3-month engagement, the hassle of maintaining a Ltd (potential dormant period, accounting costs, PAYE even for one month of salary) may outweigh the modest tax advantage.
Simplicity is genuinely valuable to you. No payroll to run, no accountant to manage, no corporation tax return to file. If you're mid-career and contracting as a stepping stone or sabbatical, the simplicity can be worth a few thousand pounds per year.
IR35 risk appetite is low. Some contractors, particularly in public sector or large financial services clients, face genuine ambiguity about IR35 status. Umbrella removes that uncertainty entirely.
You're testing a new market or rate. Before committing to the overhead of a Ltd structure, some contractors start on umbrella for a new contract or sector.
The bottom line
At realistic day rates in 2026/27:
| Day rate | Ltd net | Umbrella net | Annual gap | |---|---|---|---| | £400/day | ~£59,300 | ~£55,400 | ~£3,900 | | £500/day | ~£70,400 | ~£66,700 | ~£3,700 | | £700/day | ~£90,000 | ~£83,700 | ~£6,300 |
The Limited Company is more tax-efficient at every level — but the gap (£3,700–£6,300/yr) needs to be weighed against the compliance burden, IR35 risk, and the real opportunity cost of your time.
