An ISA lets you earn interest, dividends and investment growth completely tax-free, on up to £20,000 of contributions each tax year.
For self-employed creatives with no employer pension or savings scheme, an ISA for the self-employed is the simplest tax shelter available. The rules will change in April 2027.
Key Takeaways
- You can pay up to £20,000 into ISAs each tax year, and everything they earn is free of income tax and capital gains tax.
- The allowance resets every 6 April and unused allowance is lost.
- A Lifetime ISA adds a 25% government bonus worth up to £1,000 a year if you open one between 18 and 39.
- Pension contributions usually beat ISAs for higher-rate taxpayers because relief is paid at your marginal rate.
- ISAs never appear on your Self Assessment return – there is nothing to declare.
- From April 2027, under-65s can only put £12,000 a year into a cash ISA, although the overall £20,000 allowance stays.
- Interest on cash parked inside a stocks and shares ISA will face a 22% charge from April 2027.

1. What an ISA does for you when you’re self-employed
An ISA is not an investment. It’s a wrapper you put around one. Inside that wrapper, interest, dividends and capital gains are all tax-free, and they stay tax-free for as long as the money sits there. Outside it, savings interest and investment returns count as income and gains like anything else.
That distinction matters more when you work for yourself.
Roughly a third of the UK’s creative workforce is self-employed, which means no workplace pension, no employer savings scheme, and no one nudging you to put anything aside.
Understanding how income tax works on your profits is half the picture… the other half is protecting whatever those profits earn once you’ve saved them. An ISA does that job with no ongoing admin at all.
2. How the ISA allowance works
The allowance is £20,000 per tax year for the 2026/27 year, shared across every ISA you pay into. It refreshes on 6 April and anything unused simply disappears. There is no carry-forward, which is worth remembering in a good earning year.
A few mechanics trip people up, so here they are in plain terms:
- You can split the £20,000 across ISA types however you like – £14,000 cash and £6,000 stocks and shares works fine.
- Since April 2024 you can pay into more than one ISA of the same type in the same year, apart from Lifetime ISAs.
- Lifetime ISA contributions are capped at £4,000 a year, and that £4,000 counts within your £20,000, not on top of it.
- Transfers between providers do not use up allowance, as long as the provider handles the transfer. Withdrawing and re-depositing yourself does.
3. The four types of ISA and who each one suits
This section compares the four ISA types available to adults, because picking the wrong one is the most expensive mistake on this page.
Cash ISA
A savings account inside the wrapper.
Interest is tax-free, the balance can’t fall, and easy-access versions let you pull money out whenever a quiet month demands it. This is where your emergency fund belongs. The trade-off is growth: cash loses ground to inflation over long periods.
Stocks and Shares ISA
An investment account inside the wrapper:funds, shares, bonds, whatever the platform offers.
No capital gains tax, no dividend tax, ever. Values go down as well as up, so this suits money you won’t need for five years or more.
Lifetime ISA
Open one between 18 and 39 and the government adds 25% to everything you pay in, up to £1,000 of free money a year on the £4,000 cap.
The catch is access: withdraw for anything other than a first home (up to £450,000) or after age 60 and you lose 25% of the withdrawal, which costs you more than the bonus gave you. Note that the government has announced plans to replace the Lifetime ISA with a new first-time buyer ISA from 2028, with existing account holders expected to keep their accounts – verify the latest position before opening one.
Innovative Finance ISA
Peer-to-peer lending and similar assets inside the wrapper.
Returns can look attractive, but the underlying loans are not protected by the FSCS and your capital is genuinely at risk. For most creative freelancers this is a niche option, not a starting point.
4. ISA or pension when you work for yourself
A pension gives you tax relief going in and taxes you coming out.
An ISA is the reverse: you pay in from taxed income, then withdrawals are tax-free. Which wins depends mostly on your marginal tax rate today versus your likely rate in retirement.
| ISA | Pension | |
|---|---|---|
| Tax going in | Paid from taxed income, no relief | Relief at your marginal rate (20%, 40% or 45%) |
| Tax coming out | Completely tax-free | 25% tax-free, the rest taxed as income |
| Access | Any time (Lifetime ISA excepted) | From age 55, rising to 57 in 2028 |
| Annual limit | £20,000 | Up to £60,000, capped at your earnings |
| Best for | Flexibility and medium-term goals | Long-term retirement saving, higher-rate taxpayers |
If you pay higher-rate tax in a strong year, pension contributions are hard to beat: £60 of your money becomes £100 invested once relief is claimed through Self Assessment.
In practice most self-employed people end up using both: pension for the long game, ISA for everything they might need before 57.
Note: Getting the split right in a variable-income year is exactly the kind of question tax planning for creatives is built to answer.
5. Making ISAs work with irregular creative income
Project-based income changes how you should use the wrapper.
So, build the safety net first: three to six months of essential costs in an easy-access cash ISA, so a slow quarter never forces you to sell investments at a bad moment or raid money earmarked for tax.
Look for a flexible ISA.
Flexibility here has a specific meaning: you can withdraw money and replace it within the same tax year without the replacement counting against your allowance. For anyone whose cash flow lurches between invoices, that feature is worth more than a slightly better interest rate.
Forget the tidy monthly direct debit if it doesn’t fit your year.
Contributing in lumps after big invoices land is a perfectly good strategy: the allowance doesn’t care about rhythm, only the 5 April deadline.
One structural point: ISAs hold personal money. If you trade through a limited company, cash has to come out as salary or dividends before it can go in, which is one of the quieter factors in the sole trader or limited company decision.
6. ISAs and your tax return
You do not declare ISAs on your Self Assessment return. Not the contributions, not the interest, not the gains.
HMRC gets what it needs from your provider, and there is no box for any of it.
You might wonder why an ISA matters at all when the Personal Savings Allowance already gives basic-rate taxpayers £1,000 of tax-free interest (£500 at higher rate, nothing at additional rate).
Three reasons:
- the allowance shrinks as your earnings rise,
- today’s interest rates burn through it faster than people expect
- and ISA protection compounds year after year while the PSA resets.
If untaxed earnings are on your mind more broadly (e.g. a print shop on the side, some affiliate income) the side hustle tax rules are a separate matter and very much do belong on your return.
7. The ISA rules are changing in April 2027
From 6 April 2027, the amount under-65s can pay into a cash ISA drops from £20,000 to £12,000 a year. The overall £20,000 allowance stays and the remaining £8,000 can go into a stocks and shares or innovative finance ISA.
Savers aged 65 and over keep the full £20,000 cash limit.
Two follow-up rules announced in June 2026 close the obvious workarounds:
- Interest earned on cash held inside a non-cash ISA (such as a stocks and shares ISA) will be charged at 22% from April 2027, so parking cash in an investment wrapper stops working.
- Transferring a stocks and shares ISA back into a cash ISA will no longer be allowed.
What to do with the window you still have:
- The full £20,000 cash limit applies until 5 April 2027, so heavy cash savers can shelter more now.
- Existing cash ISA balances are unaffected – whatever is sheltered stays sheltered.
- If you were planning to move investments back into cash, decide before the transfer route closes.
These measures were announced at Autumn Budget 2025 and detailed in 2026 government factsheets, but secondary legislation can still shift the fine print – confirm the final rules on GOV.UK closer to April 2027.
8. Getting your savings working as hard as you do
WallsMan Creative are ACCA-regulated accountants who work exclusively with the UK’s creative industries: freelancers, studios, agencies and production companies whose income rarely arrives in twelve neat monthly instalments.
Questions about where savings, pensions and tax planning meet are everyday territory for the team, precisely because irregular income makes the textbook answers unreliable.
The short version of this guide: use the wrapper. Up to £20,000 a year grows free of tax, nothing touches your Self Assessment, and the right mix of cash, investments and pension depends on your tax rate and how soon you’ll need the money. The 2027 cash ISA cap gives heavy cash savers a reason to act sooner rather than later.
If you’d like to talk through how ISAs, pensions and your business structure fit together – before the rules move again – the team would be glad to have that conversation.
