Employed or Self-Employed on £55k? The Real Difference
£55,000 employed versus £55,000 self-employed: the calculated take-home difference, what employee benefits are worth, and when each side wins.
Direct answer: At £55,000 gross, a sole trader keeps about £43,211 a year versus £42,457 as an employee — £754 more, before pricing in the value of employee benefits.
Assumptions: England, Wales or Northern Ireland; 2026/27 rates; profit after allowable expenses; standard Personal Allowance; no pension or student loan unless stated.
The calculated comparison
| On £55,000 gross | Employed (PAYE) | Self-employed |
|---|---|---|
| Income Tax | £9,432 | £9,432 |
| National Insurance | £3,111 (Class 1) | £2,357 (Class 4) |
| Take-home a year | £42,457 | £43,211 |
| Take-home a month | £3,538 | £3,601 |
Same gross, different system
Employees pay Class 1 National Insurance, and their employer pays a further contribution on top invisibly. Sole traders pay the cheaper Class 4 with no compulsory Class 2 charge on top, which is why the self-employed column of the calculated table keeps more at the same gross. The difference is real — but it is not the whole story.
What the headline difference hides
The self-employed advantage narrows or reverses once you price what employment includes: employer pension contributions, paid holiday, sick pay, parental leave and no accountancy overhead. A contract rate that merely matches a salary is usually a pay cut once those are valued honestly. The tax saving is the easy part to calculate; the benefits gap is the easy part to forget.
- Value the employer pension contribution before comparing gross figures.
- Price in at least four weeks of unpaid holiday and a sick-pay buffer.
- Add accountancy fees and the cost of your own bookkeeping time.
- Remember the whole self-employed bill arrives in January, not monthly via PAYE.
- Consider a personal pension to close the retirement-saving gap.
When self-employment genuinely wins
Where allowable expenses are genuine, where you control when profit is taken, and where pension contributions can be timed around the higher-rate threshold, the self-employed structure can beat employment on tax as well as flexibility. Test your own figures in the calculators linked below rather than relying on a single headline number — and remember that the comparison changes again above the personal-allowance taper.
