A loan is a benefit, not a way around the matching rules
The UK does not only tax formal distributions from offshore trusts. Where the settlor is not taxable on the arising basis, income and gains inside the structure can still reach UK-resident beneficiaries through the benefit and capital-payment matching rules, and a capital payment includes the transfer of an asset or the conferring of any other benefit. An interest-free or soft loan confers exactly such a benefit: HMRC's own manual calls these loans the most common benefits giving rise to capital payments. A genuinely commercial loan, made at a full arm's length rate that is actually paid, is a different animal from an undocumented family advance, which is why the terms and the paperwork matter so much.
How the benefit of a loan is measured
For an interest-free or cheap loan, the benefit is broadly the interest the beneficiary would pay an unconnected lender at a commercial rate but does not pay, with the Treasury's official rate of interest used as the yardstick for sterling loans. A loan repayable on demand gives rise to a benefit that accrues year by year for as long as it is outstanding, while a fixed-term loan can be valued when it is made, and statutory rules valuing certain capital payments were introduced by Schedule 14 Finance (No 2) Act 2017. The measured benefit is then matched to the trust's pool of income and gains in the same way as a distribution, so a large loan left outstanding for years can quietly build up a significant matched charge.
Why 2025 changed the calculation
Two changes reshape the loan-versus-distribution choice. First, protected settlement status was abolished from 6 April 2025, so a UK-resident settlor outside the four-year FIG regime is generally taxed on the trust's worldwide income and gains as they arise, making deferral by lending rather than distributing pointless in those cases. Second, historic foreign income and gains that arose before 6 April 2025 generally remain outside charge until matched to a benefit, and where matching is to those pre-6 April 2025 amounts the Temporary Repatriation Facility can allow the value to be brought onshore at 12% in 2025/26 and 2026/27, rising to 15% in 2027/28. The right sequencing between loans, distributions and TRF designation is highly fact-specific and the low rate window is short.
