The UK’s frozen tax thresholds and rise in tax on dividends could be pushing more self-employed workers to consider Jersey’s 20% income tax cap. But once you factor in social security and living costs, which location leaves you better off?
The UK’s tax squeeze gets tighter
Self-employed workers in the UK face growing pressure from Chancellor Rachel Reeves’ Autumn 2025 Budget. The personal allowance (£12,570) and all tax bands will stay frozen until 2031, meaning more people will be dragged into higher tax brackets as their earnings rise with inflation.
The Budget, as previously reported by The Freelance Informer, also confirmed plans to increase taxes on savings, dividends and rental income by 2% from 2027. A new council tax surcharge will hit properties worth over £2 million from 2028.
Here we outline more of the tax implications:
UK tax rates (2025/2026)
Income Tax (England, Northern Ireland, and Wales)
| Tax Rate | Rate | Taxable Income Band |
| Basic Rate | 20% | £12,571 to £50,270 |
| Higher Rate | 40% | £50,271 to £125,140 |
| Additional Rate | 45% | Over £125,140 |
- The first £12,570 of income is generally covered by the tax-free Personal Allowance. The Personal Allowance is reduced for income over £100,000.
Scotland: Scotland has different tax bands and rates. For instance, the top rate is 48% on income over £125,140, and the higher rate is 42% on income between £43,663 and £75,000.
Self-Employed National Insurance (Class 4):
| Rate on Profits | Thresholds |
| 6% | Between £12,570 and £50,270 |
| 2% | Above £50,270 |
Note: These rates apply to annual profits for the 2025/2026 tax year.
- Class 2 NICs, which used to be a weekly flat rate for the self-employed, are generally not paid for profits over £6,845, but you are treated as having made the contributions to protect your National Insurance record
- The standard VAT rate stands at 20%
Jersey’s appeal: Low income tax but higher social costs
Jersey’s main attraction is simple: income tax is capped at 20%, no matter how much you earn. Single residents also get a generous tax-free allowance of £20,700 for 2025.
There’s a helpful calculation called Marginal Relief that often reduces your tax bill below 20% if you’re a lower or middle earner. The system always charges you whichever is less: the standard 20% rate or the marginal calculation.
The catch: Higher social contributions
However, Jersey requires much higher mandatory contributions:
- Jersey Social Contribution Rates (2025)
- Social Security: 12.5% on earnings up to £69,600, plus 2.5% on earnings up to £317,304
- Long-Term Care: Additional 1.5% on all earnings up to £317,304
- Combined rate on first £69,600: 14.0%
- GST (Goods and Services Tax): 5% standard rate
Self-employed people in Jersey pay 14.0% in combined social contributions on their first £69,600 of earnings. This is significantly more than the 6% National Insurance rate UK workers pay on profits between £12,570 and £50,270.
Jersey’s tax system change for couples
Jersey is moving from taxing married couples as one unit to taxing individuals separately. This is now mandatory for anyone moving to Jersey, and will apply to all taxpayers from 1 January 2026.
Let’s compare the actual tax bills for a self-employed person earning £80,000 a year:
| Item | UK | Jersey |
| Income Tax | £14,404 | £15,418 |
| Social Contributions | £2,857 | £10,160 |
| Total Tax | £17,261 | £25,578 |
| Effective Rate | 21.5% | 32.0% |
The verdict on direct tax
For this income level, Jersey’s total tax bill is £8,317 higher than the UK’s. The Channel Island’s 14.0% social contribution rate (applied to nearly £70,000 of income) wipes out any savings from avoiding the UK’s 40% tax bracket.
Where Jersey wins: Spending and wealth
Jersey’s advantage isn’t in direct tax—it’s in what you pay when spending and building wealth.
Lower living costs (excluding housing)
The difference between the UK’s 20% VAT and Jersey’s 5% GST means major savings on everyday purchases. This significantly increases your disposable income and reduces the cost of living.
Wealth protection
Jersey has:
- No Capital Gains Tax (CGT)
- No Inheritance Tax (IHT)
- No wealth taxes
For anyone building substantial assets or planning to pass wealth to family, Jersey offers long-term stability. This is particularly attractive given the UK’s recent Budget specifically targeted these areas for higher taxation.
Which is right for you: UK or Jersey?
The choice depends on your priorities:
Consider the UK if:
- You earn under £70,000 and want lower social contributions
- You’re focused on current income rather than long-term wealth
- You need immediate cash flow
Consider Jersey if:
- You want to minimise what you pay on purchases (5% vs 20%)
- You’re building significant wealth and assets
- You want to protect inheritance for your family
- You value long-term wealth preservation over short-term savings
The bottom line
The UK is cheaper for funding social security and keeping more of your immediate earnings. Jersey is cheaper for spending your money and protecting your wealth over time.
For most self-employed workers earning typical salaries, the UK’s lower social contributions make it the better choice. But for high earners focused on building and preserving wealth, Jersey’s lack of capital gains and inheritance taxes could save hundreds of thousands of pounds over a lifetime.
