He's used the wrong table but corrected it and pointed out that for married couples the exemption will work out higher.
He (and everyone I have read on twitter) is still actually slightly wrong on this.
I think he's correct that it's the usual nil rate bands*, plus £1m agricultural relief per spouse. However, this would only be if the first spouse to die leaves their share to their children, claiming their own nil rate bands, and their £1m agricultural relief. The surviving spouse would then use their nil rate bands and their £1m agricultural relief on their passing. It wouldn't quite work if the first spouse to die gives their share to the surviving spouse. If they were to leave their share to the surviving spouse, then that would be covered by spouse exemption, and then the surviving spouse would pass the full value to the children when they die, but although they could transfer the first spouse's NRB and TNRB, they would only have their £1m agricultural relief, not theirs and their spouses (
source). But if they do it correct, then between them a couple could potentially leave £3m free of IHT. However, this method might not be possible - if assets are owned as joint tenants, rather than tenants in common - the former would mean the assets pass by survivorship to the surviving spouse regardless of what the will says. And HMRC would likely pursue that. Some wills will need to be re-written, and joint tenancies severed. It's fair to say many farmers likely won't get their affairs in order, and wouldn't be able to claim the £1m agricultural relief for each spouse. I think they might be able to adjust the will after death, but I don't know if they could change ownership from joint tenants to tenants in common after death (I guess not?). It does seem a bit unfair that unused agricultural relief can't be transferred to the surviving spouse like NRB and RNRB are - as ultimately it will just punish people who don't prepare their finances in advance, which are generally those with less income to spend on a financial advisor.
*The other thing is taper on RNRB, and I haven't seen anyone get this right. Currently, everyone is entitled to £325k NRB, plus
upto £175k RNRB. However, the RNRB is impacted by
the taper threshold. This has been £2m for years. So, if an estate is over £2m
before exemptions, then they lose RNRB to the tune of £1 for every £2 over £2m. Therefore, if a single farmer has a farm worth £2.1m, then he wouldn't have 325k NRB + 175k RNRB + 1m agricultural relief, they would only have 325k NRB + 125k RNRB + 1m agricultural relief. Interestingly though, the taper threshold is due to increase from 27/28 onwards.
If a couple own a £5m farm, as joint tenants, and the surviving spouse inherits from the passing spouse first, then they will only have 325k NRB + 325k TNRB + 1m agricultural relief, completely losing the RNRB and the 2nd 1m agricultural relief, resulting in a £670k tax bill (assuming no change in thresholds between first and second death). If instead, the farm is owned as tenants in common and the first spouse leaves their £2.5m share to their children, then they will have 325k NRB + 1m agricultural relief, but no TNRB, resulting in a 235k tax bill on the passing of the first spouse, and the surviving spouse would then have the same reliefs and same tax bill (unless NRB increased between deaths or change in farm value). If the estate is £4m, then the first method would result in 650k NRB/TNRB + 1m agricultural relief (470k tax) whereas the second method, they would have 650k NRB, plus 350k RNRB + 2m agricultural relief (200k tax).
I think I should set up an estate planning business for farmers. They are the big winners here. The feckers even charge a % of the estate value in some cases. Also, the kids should just sell up, bank several million and make a much higher return than they would retaining the farm (especially if they have to pay interest on the tax bill either by paying by installments or taking out a loan to pay it off). I don't see why people are so up in arms about this, other than seemingly a conspiracy theory that this is in order for the government and/or Bill Gates to buy up all the farms and make us eat bugs.
