RE: Exemption from Inheritance Tax30 Mar 2022 21:00
The short answer is that when the day comes to fill in the forms for Probate, you (or your solictor) will complete the figure of the assets that you believe should qualify for BPR and therefore be exempt from IHT.
HMRC then pretty much choose whether they want to contest it or not. I've see it challenged a couple of times, but as we've been using specific IHT managers like Octopus, they don't go much beyond querying it. In other cases where it's been a legitimate family business, more info as to whether it's a qualifying company has been required.
Most IHT managers will keep an eye on the market cap of the businesses in the portfolio and they're likely to 'ditch' them if they get too big. That probably doesn't help answer the question definitively, but the bottom line is that it's not actually black and white... as is so often the case with our beloved tax man.
The below link offers a bit more on the technical detail and some references to the HMRC internal manual, for those of you who want to ruin a perfectly pleasant Wednesday evening.
