Angela Rayner’s Stamp Duty Error: Where It Went Wrong—and What You Should Know

Deputy Prime Minister Angela Rayner has admitted she underpaid around £40,000 in stamp duty on the purchase of an £800,000 seaside flat in Hove. The mistake stemmed from complex trust rules that changed how HMRC treated the purchase.

Here’s what happened, what went wrong, and what you can learn to avoid similar issues.

What actually happened?

In May 2025, Rayner bought a flat and paid £30,000 in stamp duty, the rate for a main residence.
She had previously transferred her old family home into a trust for her disabled son.
Under law, beneficiaries of such trusts are still treated as owners — meaning the Hove property counted as a second home.
The correct bill was £70,000, leaving an underpayment of about £40,000.

She relied on professional advice at the time, but none of her advisers flagged the issue. She has since referred herself to HMRC and the government’s ethics adviser.

Where did things go wrong?

Trust rules are complex – HMRC treats certain trusts as if the beneficiary still owns the property.
Conflicting records – Rayner had declared her old home as a main residence for council tax, while claiming her new flat as her primary residence for stamp duty.
Advice gap – her conveyancer and trust advisers didn’t spot the deeming rule that applied.

What should she have done differently?

Seek specialist tax advice for unusual situations involving trusts or multiple properties.
Check consistency – make sure council tax, electoral roll, and HMRC records all match.
Document assumptions – written confirmation of how rules apply can protect against penalties later.

Could there be penalties?

HMRC will normally require:

The underpaid tax (£40,000)
Interest on the amount
A penalty – usually up to 30% for a “careless” error, but often reduced if the taxpayer cooperates.

In Rayner’s case, penalties could be around £6,000–£12,000 depending on HMRC’s assessment.

What can readers learn from this?

Always double-check property tax rules when trusts or multiple homes are involved.
Don’t rely only on conveyancers – they may not cover unusual tax implications.
When in doubt, disclose – voluntary correction with HMRC can reduce penalties.
Consistency matters – keep your main residence status aligned across all records.
