Possible IHT reduction

Postby RolfF » Fri Jun 05, 2026 8:07 am

My brother has been widowed since 2002 and is now in very poor health.

He has asked me to be executor for his estate and I seem to think there's something about the tax allowance of his late wife that could be used to reduce IHT?

I have little knowledge of tax, so any help would be welcome.

Thank you.

R,

The first thing to clarify - and it is intensely annoying to professional advisers that so many people are 'scared' of IHT without needing to be - is whether or not your brother's anticipated Estate (broadly, his net wealth) will be exposed to IHT at all.

He would need to be 'worth' more than the current Nil-Rate Band (NRB) of £325k net in order for there to be any potential exposure.

On top of that - and this is where his late wife is a factor - it is often the case that he will have 'inherited' his late wife's NRB assuming she left everything to him, on her earlier death.

So, in a simple scenario involving the second death of a married couple/civil partnership, net wealth must exceed £650k.

2 key influencing factors are:

Did she leave wealth to others, that may have eroded the availability of her NRB to your brother on his death?
Are they leaving their main / family home to their kids/grandchildren, in which case the available exemptions can rise from £650k to potentially as much as £1million?

IHT can be hellaciously complex, but in very many cases, it simply isn't a problem in the first place, because net wealth is insufficient to trigger it.

Of course, it is almost certain that if I start with this point, your brother's wealth WILL exceed these thresholds. Such is the way that TW forum queries work.
I am assuming that both your brother and his wife are/were very long-term residents in the UK, or else other complicating factors may need to be considered.

With regards,

Lambs

Thank you for your helpful reply, Lambs.

The estate is estimated between £500K - £550K.

They had no children and she had no beneficiaries in her will - all passed to her husband.

R,

Then on the facts as presented, you will need actively to claim the late wife's NRB as 'inherited' by your brother (by dint of its not having been used already/elsewhere) if, as and when he dies. As I understand things, while a full Estate Return may not be necessary where no IHT is actually due, the IHT402 is still appropriate for such claims. Very importantly, there is a 2-year time limit for claiming unused NRB in this way (strictly, 2 years from the end of the month in which the second spouse dies). For an Estate of that size, I should recommend you engage a good adviser - solicitor, tax adviser, or similar. The paperwork can be voluminous, and you will likely not want to have to deal with it.

Apologies if this comes across as cold: when I was younger I was very circumspect/deferential around death. I was invariably told to "stop pussy-footing around" it. I have come to understand it is simpler this way. But nor am I offering my services: we do have a couple of contributors on here who do a fair bit of IHT work in their "day jobs" but I am not one of them.

With regards,

Lambs
