An Innovative Finance ISA (IFISA) is a tax-efficient way to invest in peer-to-peer lending (P2P) and other alternative finance products. It combines the tax benefits of a regular ISA with the potential for higher returns — but also comes with higher risks.
This guide explains how IFISAs work, their pros and cons, and strategies to help you decide if they’re right for you.
1. What Is an Innovative Finance ISA?
Launched in 2016, IFISAs allow UK investors to use their annual £20,000 ISA allowance to lend money via regulated platforms. Your money is typically lent to:
- Individuals (personal loans)
- Small businesses (SMEs)
- Property developers (bridging loans, buy-to-let, or commercial projects)
In return, you earn interest — which is 100% tax-free within the IFISA wrapper.
2. Key Benefits of IFISAs
Benefit | Why It Matters |
---|---|
Tax-Free Returns | No income tax or capital gains tax on your interest. |
Higher Potential Yields | Returns often range between 4% and 10%, higher than Cash ISAs or even some investment funds. |
Portfolio Diversification | Add an alternative asset class to balance traditional stocks and bonds. |
Support for Businesses | Your money helps SMEs or property developers grow. |
3. Risks of IFISAs
While the potential returns are attractive, IFISAs carry higher risks, such as:
- Borrower Defaults – If borrowers fail to repay, you could lose money.
- Platform Risk – If the lending platform collapses, your funds may be at risk.
- No FSCS Protection – Unlike Cash ISAs, IFISAs are not protected by the Financial Services Compensation Scheme.
Tip: Only invest money you can afford to leave untouched and consider spreading your funds across multiple loans.
4. IFISA vs. Other ISAs
Feature | IFISA | Stocks & Shares ISA | Cash ISA |
---|---|---|---|
Risk Level | High | Medium | Low |
Typical Returns | 4%–10% | 4%–8% (long-term) | 2%–5% |
Liquidity | Medium (depends on platform) | High | High |
Tax-Free | Yes | Yes | Yes |
5. Example of IFISA Growth
If you invest £10,000 in an IFISA earning 7% annual interest, your investment could grow to:
- Year 1: £10,700
- Year 5: £14,025
- Year 10: £19,671
All of this tax-free compared to taxable interest outside an ISA.

6. How to Open an IFISA
Opening an IFISA is straightforward:
- Choose a FCA-Regulated Platform – Popular providers include Assetz Capital, CrowdProperty, or Funding Circle.
- Compare Returns and Risk – Check historical performance and default rates.
- Transfer or Deposit Funds – Use part of your annual £20,000 allowance.
- Diversify – Spread your money across multiple loans for added protection.
7. Strategies for Maximising Your IFISA
- Diversify Your Portfolio – Don’t put all your money into one loan or sector.
- Reinvest Interest – Compounding your returns over time accelerates growth.
- Use It Alongside Other ISAs – Combine an IFISA with a Stocks & Shares ISA for a balanced portfolio.
- Stay Updated – Review your platform’s performance regularly.
Final Thoughts
An IFISA can be a powerful addition to your investment strategy, offering tax-free, potentially high returns. However, the risks are real, and these accounts are best for experienced investors who understand peer-to-peer lending.
By carefully choosing platforms, diversifying your portfolio, and monitoring your investments, you can make the most of your IFISA allowance while managing the risks effectively.
