PAYE vs Self-Employed: Which Leaves You Better Off?

If you are weighing up PAYE vs self employed work, the honest answer is that neither is automatically better — it depends on how you value money you can see versus protections you cannot. Many people assume self-employment always pays more because there is no boss taking a cut, while others assume employment is safer and simpler. Both contain a grain of truth. The aim of this guide is to show you exactly where the differences come from, so the choice between employed vs self employed becomes a clear-eyed decision rather than a hunch.

We will use the 2026/27 tax year figures throughout (6 April 2026 to 5 April 2027), and we will keep the maths in plain English.

The one thing that is the same: income tax

This surprises a lot of people. Income tax works identically whether you are employed or self-employed. You get the same Personal Allowance (£12,570 for 2026/27, the slice you can earn before any tax), and the same bands apply on top of it:

• Basic rate — 20% on the next £37,700 of taxable income
• Higher rate — 40% above that, up to £125,140
• Additional rate — 45% on income over £125,140

An employee on £40,000 and a sole trader making £40,000 profit pay exactly the same income tax. So if the income tax is identical, where does the difference in take-home come from? Two places: National Insurance, and what counts as your taxable figure in the first place.

Where it differs: National Insurance

National Insurance (NI) is the real fork in the road, because employees and the self-employed are in different classes with different rates.

Employees pay Class 1

If you are on PAYE, your employer deducts Class 1 NI before you are paid. For 2026/27 that is 8% on earnings between £12,570 and £50,270, then 2% on anything above £50,270. You never see this money — it leaves your payslip automatically.

The self-employed pay Class 4 (and maybe Class 2)

If you work for yourself, you pay Class 4 NI through Self Assessment: 6% on profits between £12,570 and £50,270, then 2% above £50,270. Notice the main rate is 6% rather than 8% — that two-point gap is the main reason self-employed take home pay can edge ahead of an employee on the same headline figure.

There is also Class 2 NI, a flat £3.65 a week. For most self-employed people with profits above the small profits threshold (£7,105), Class 2 is now treated as paid automatically without you handing over the cash, which protects your State Pension record. If your profits are below that, you can pay Class 2 voluntarily to keep your contribution years ticking over — often a very cheap way to protect future entitlements.

Expenses: the self-employed advantage

The second difference is what you are taxed on. An employee is taxed on gross salary, full stop. A self-employed person is taxed on profit — income minus allowable business expenses. That means costs you genuinely incur to do the work come off before tax is calculated.

Typical allowable expenses include a proportion of home-office costs, business travel and mileage, tools and equipment, professional subscriptions, software, accountancy fees and marketing. If a sole trader on £40,000 of income has £5,000 of legitimate expenses, they are taxed on £35,000, not £40,000. Employees simply do not have this lever (beyond a few narrow reliefs).

A word of caution: expenses must be genuine and “wholly and exclusively” for the business. This is a real benefit, not a loophole — keep records and receipts.

Compare the two side by side

A worked example on £40,000

Let us put real numbers on it. Take someone employed on a £40,000 salary, and a sole trader making £40,000 profit (we will assume no expenses, so the comparison is fair).

Income tax (both): (£40,000 − £12,570) × 20% = £5,486. Identical for each.

Employee Class 1 NI: (£40,000 − £12,570) × 8% = £2,194.40.
Take-home: £40,000 − £5,486 − £2,194.40 = £32,319.60.

Self-employed Class 4 NI: (£40,000 − £12,570) × 6% = £1,645.80.
Take-home: £40,000 − £5,486 − £1,645.80 = £32,868.20.

So on identical figures, the sole trader keeps roughly £549 more — purely because of the lower NI rate. Add a few thousand pounds of genuine expenses and the gap widens further, because that money never gets taxed at all. This is why people say self employed take home pay tends to win on paper.

What take-home pay doesn’t show

Here is where the “is self employed better than employed” question gets interesting. The £549 advantage above is real, but it is not free money — it is partly compensation for everything an employer would otherwise give you. Take-home pay is a number; security is not, and the comparison only makes sense once you price in the things that never appear on a calculator.

• Paid holiday. Employees get a statutory minimum of 5.6 weeks’ paid leave. A self-employed person who takes four weeks off simply earns nothing for four weeks. On a £40,000 income that is roughly £3,000 of foregone earnings — far more than the NI saving.
• Sick pay. Employees get Statutory Sick Pay; the self-employed get nothing. One bad bout of illness can wipe out months of the NI advantage.
• Maternity and paternity. Employees may receive statutory pay and protected leave. The self-employed can claim Maternity Allowance, but there is no equivalent paternity pay.
• Employer pension contributions. Under auto-enrolment your employer must pay in on top of your salary — effectively free money toward your retirement. As a sole trader you fund 100% of your own pension.
• Stability and admin. A salary lands on the same day every month with tax already handled. Self-employment means variable income, chasing late payers, keeping records and filing a tax return — and setting money aside for a January bill.

Once you add up holiday, sick pay and an employer pension match, the modest take-home edge from self-employment often shrinks or reverses. That does not make employment “better” — many people happily trade those protections for autonomy, variety and the ability to scale their income. It just means the headline take-home figure is only one part of the picture.

Pension: a responsibility that shifts entirely

This deserves its own flag because it is the difference most easily overlooked. As an employee, auto-enrolment quietly builds a pension with your employer contributing alongside you. The moment you go self-employed, that scaffolding disappears. Nobody enrols you, nobody tops you up, and it is entirely on you to open a personal pension or SIPP and to actually pay into it. The tax relief is still generous, but the discipline has to come from you.

A quick word on IR35 for contractors

If you contract through your own limited company, you may run into the off-payroll working rules (IR35). In short, IR35 asks whether you are genuinely in business on your own account, or whether you are effectively an employee of your client in all but name. If a contract is judged “inside IR35”, you are taxed much more like an employee and most of the take-home advantage vanishes. If you are considering contracting rather than straightforward sole-trader self-employment, get the IR35 status of each engagement assessed properly — it materially changes the numbers.

How to decide

There is no universal winner, but these questions help:

• How much do you value certainty? If a steady income and benefits matter, PAYE earns its keep.
• Do you have real, claimable expenses? The more genuine business costs you carry, the stronger the self-employed case.
• Can you handle variable income and admin? Self-employment rewards organisation and self-discipline.
• Will you actually fund your own pension and tax bill? Be honest — the NI saving is no bargain if it is spent rather than set aside.

FAQs

Is self-employed better than employed for take-home pay?

On identical figures, self-employed usually edges ahead because Class 4 NI (6%) is lower than employee Class 1 NI (8%), and you are taxed on profit after expenses. But once you price in paid holiday, sick pay and employer pension contributions, the gap often closes or reverses.

Do employed and self-employed pay the same income tax?

Yes. The Personal Allowance and the 20%, 40% and 45% bands are identical. The differences come from National Insurance and from being taxed on profit rather than gross salary.

What is the difference between Class 1 and Class 4 National Insurance?

Class 1 is paid by employees automatically through payroll at 8% then 2% for 2026/27. Class 4 is paid by the self-employed through Self Assessment at 6% then 2%, often alongside flat-rate Class 2.

Should I choose PAYE or self-employed?

Choose PAYE if you value income stability, benefits and an employer pension. Choose self-employment if you want autonomy, have genuine business expenses and can manage variable income, your own pension and a tax return.

What is IR35 and does it affect me?

IR35 (off-payroll working rules) applies to contractors working through their own company. If your engagement is “inside IR35”, you are taxed much like an employee and most self-employed tax advantages disappear. Sole traders are not affected in the same way.
