Using IFISA funds for tax efficiency
30 March 2026 | 3 min read
For higher and additional-rate taxpayers, combining property bridge lending with an IFISA can improve after-tax income, diversify portfolio risk, and add asset-backed exposure to a wider wealth strategy.
For higher and additional-rate UK taxpayers, generating meaningful income without heavy tax drag has become increasingly difficult. Dividend allowances have been reduced, capital gains exemptions cut, rental income is taxed at marginal rates, and traditional fixed income often struggles to keep pace with inflation.
In this environment, net returns matter more than headline yields. One structure worth closer attention is combining property bridge lending with an Innovative Finance ISA (IFISA).
THE TAX ADVANTAGE
If you pay income tax at 40% or 45%, the impact on compounding is significant. Interest earned outside a tax wrapper is taxed at your marginal rate.
For example:
- Gross return: 9%
- Additional-rate tax (45%)
- Net return outside ISA: 4.95%
- Net return inside IFISA: 9%
That difference compounds materially over time. Returns within an ISA, under HMRC rules, are free from income tax, dividend tax, and capital gains tax. While many investors use Stocks & Shares ISAs, fewer fully utilise the IFISA.
WHAT IS AN IFISA?
An Innovative Finance ISA allows individuals to hold peer-to-peer and alternative lending investments within the ISA wrapper. Unlike a Cash ISA (typically low yield) or Stocks & Shares ISA (equity exposure), an IFISA provides access to private credit and secured lending opportunities.
For income-focused investors, this can be particularly attractive.
UNDERSTANDING PROPERTY BRIDGE LENDING
Property bridge lending involves short-term loans - typically 6 to 18 months - secured against UK property. Borrowers use bridging finance to acquire property quickly, fund refurbishments, or bridge to longer-term finance.
Key features often include:
- Security via legal charge
- Defined loan term
- Contracted interest rate
- Loan-to-value (LTV) controls
Rather than owning property directly - with tenants, voids, and regulatory complexity - investors participate as lenders secured against real assets.
WHERE IT FITS IN A PORTFOLIO
Property bridge lending should complement, not replace, core equity exposure. Within a diversified portfolio, it can serve as:
An Income Sleeve - Providing defined, tax-free income alongside dividend equities or bonds.
Diversification from Public Markets - Returns are primarily driven by borrower performance and asset security, rather than daily stock market volatility.
Property Exposure Without Landlord Burden - Investors gain exposure to property-backed returns without operational management or Section 24 tax restrictions.
Short-Duration Capital Deployment - Bridging loans typically recycle capital faster than long-dated bonds or direct property ownership.
RISKS TO CONSIDER
Higher yields reflect higher risk. Investors should assess:
- Borrower default risk
- Property market risk
- Liquidity constraints
- Platform underwriting standards
- Lack of FSCS protection
Diversification across multiple loans and disciplined allocation are essential.
SENSIBLE ALLOCATION
In most portfolios, private credit forms part of a broader fixed-income or alternatives allocation. For many investors, a 5-15% exposure to property-backed lending can enhance yield while improving diversification.
The exact allocation depends on liquidity needs, risk tolerance, and existing property exposure.
FINAL THOUGHTS
An IFISA used for property bridge lending offers:
- Tax-free income
- Asset-backed exposure
- Short-duration credit
- Diversification from public markets
It is not without risk, nor a substitute for broad diversification. But for higher-rate taxpayers seeking to improve after-tax income within a disciplined portfolio framework, it can represent a measured and intelligent addition to modern wealth strategy.
