Equity release / London

Inheritance Tax on a Mayfair Home

The £3,500,000 Mayfair average already exceeds the £1,000,000 a couple can normally pass on. That leaves about £2,500,000 exposed even for a married couple, a potential £1,000,000 at 40%.

The short answer

The £3,500,000 Mayfair average already exceeds the £1,000,000 a couple can normally pass on. That leaves about £2,500,000 exposed even for a married couple, a potential £1,000,000 at 40%.

How the allowances work on a Mayfair home

Two allowances apply. The nil rate band is £325,000. The residence nil rate band adds £175,000 when a home passes to children or grandchildren. Together that is £500,000 for one person and £1,000,000 for a couple.

At £3,500,000 the Mayfair average clears both.

Where the Mayfair exposure actually comes from

Growth is what moves an ordinary home into scope. The allowances have been frozen while property values have not been. A £3,500,000 home in Mayfair is already measured against thresholds set years ago.

The nil rate band has stood at £325,000 since 2009. Every year of price growth moves more ordinary homes toward it without anything being announced.

The local average already exceeds the single owner allowance of £500,000. Single and widowed owners here should check their position rather than assume they are under it.

What equity release does to the picture

Borrowing against the home only reduces the estate once the money is spent or given away, because the debt is repaid before anything passes on. A £1,190,000 release growing to £4,193,138 over twenty years removes that amount from what is taxed, and from what your family receives.

Reducing a tax bill by spending the asset is not usually a win on its own. It only makes sense when you wanted the money anyway. Take advice before treating it as a tax plan.
