      The House of Lords Finance Bill sub-committee has been hearing oral evidence from representatives of various professional bodies about the forthcoming changes to Inheritance Tax (IHT), Business Property Relief (BPR) and Agricultural Property Relief (APR). Whether or not the Government plan to make any changes to the proposals at this relatively late stage will be announced, presumably, on Budget Day, 26 November 2025.

      We wrote about these significant changes, that will come into effect on 6 April 2026 - a little under five months from now - in IHT Business and Agricultural property reliefs are changing and in L-Day: Inheritance Tax Business and Agricultural Property Reliefs, where we set out some of the courses of action individuals and trustees might consider. Whatever plans are being made, it is critical that affected taxpayers understand when any future IHT liabilities will need to be paid and have a plan to fund those payments.

      Future IHT liabilities

      Where individuals or trustees own assets which, to date, have qualified for 100 percent BPR or APR from IHT, from 6 April 2026 they may be subject to IHT liabilities on those assets on various occasions if their value exceeds the amount of their available £1 million allowance.

      For individuals (and their personal representatives), such liabilities will most commonly arise on their death, either on the value of the relevant assets in their estate or on gifts that they have made in the seven years prior to their death. 

      For trustees, depending on the type of trust, they may have IHT liabilities in respect of relevant assets held in the trust on 10-year anniversaries or when the assets leave the trust, or alternatively on the death of certain so called ‘life tenants’ of the trust.

      In all cases, those responsible for meeting the IHT liability will need to be clear on the ‘due date’ for payment of the IHT.

      Timing of IHT payments

      The due date for payment of an IHT liability will depend on what event triggered the IHT. The due date will always be at least six months after the triggering event, whilst for some lifetime gifts it can be later (depending on the timing of the gift in question within the tax year in which it was made). 

      Once the due date has been determined, this will be the date from which any interest payable to HMRC for late payment will run. It is not, however, necessarily the date on which the taxpayer should expect to pay the IHT. 

      For IHT arising on a deceased individual’s estate, it may be necessary in practice for their personal representatives to pay at least some of the IHT early to obtain probate. 

      Taxpayers will also wish to consider whether the IHT liability can be paid in 10 annual, equal instalments (the instalment option). Where the instalment option is available, a decision on whether to claim it will be required, which will be informed at least in part by whether the instalments will incur interest costs. 

      Future plans for the asset will also be relevant to this decision as a future sale or onward gift will normally bring the instalment option to an end.

      Whilst the Government announced on 21 July 2025 that the instalment option would be extended to all assets that qualify for BPR or APR, whether the specified circumstances for payment by instalments are met will nonetheless require consideration, as will the additional conditions for IHT liabilities arising from a death within seven years of a gift.

      Funding IHT payments

      How owners of assets which previously qualified for 100 percent BPR or APR will fund future IHT liabilities is a question many are now considering. Typically, these assets will be an interest in a business, shares in an unquoted trading company or farmland, none of which are typically easy to sell in parts to raise funds. Nor would such a course of action necessarily be desirable for the reasons considered below.

      Borrowing funds to meet the liability could be an option if a willing lender can be found and the asset is not already highly geared. That though raises the additional issue of how to service interest payments on the debt and ultimately repay it at the end of the term.

      For those in good health who have not yet reached old age, life insurance will be an option to consider.

      Where liquidity exists in the form of cash in a company whose shares are subject to an IHT charge, this could be paid out as a dividend to fund the IHT. The shareholder will be subject to income tax on the dividend, and this double tax charge will result in an effective tax rate of some 34 percent. Furthermore, if too much cash is retained in the company with a view to it being used for this purpose, it could further reduce the availability of BPR as it will be an ‘excepted asset’.

      If, alternatively, cash can be realised which receives capital treatment for tax purposes, subject to any future increase in capital gains tax rates that would be a more cost-effective route to raising funds. In certain circumstances, sale of the asset itself, in whole or part, may be a pragmatic option. In other situations, such a course of action may well be contrary to the owner’s wishes in terms of succession and, where it breaks up ownership of the asset for the future, may give rise to a plethora of non-tax issues down the line.

      There are specific legislative provisions which allow for a share buy-back by an unquoted trading company (or the holding company of a trading group) to be treated as capital for tax purposes in certain circumstances. One of those circumstances is where the proceeds are used to pay an IHT liability arising on death and which is paid within two years of death. There is an additional requirement that the IHT liability could not have been met ‘without undue hardship’ by any means other than a share repurchase. This term introduces an element of uncertainty into the provisions, as the legislation does not provide clear parameters for what constitutes ‘undue hardship’ and there is a lack of guidance or case law to rely upon here, although there is a clearance procedure. It is anticipated that HMRC may take a robust stance on such claims and affected taxpayers would be wise to proceed with caution. This was an issue discussed at the House of Lords Finance Bill sub-committee however, and it remains possible that these provisions could be relaxed or widened in some way.

      What next?

      Subject to any changes announced by the Government in the Budget, taxpayers who are going to be affected by the BPR and APR changes with effect from 6 April 2026 need to ensure that they understand when a future IHT liability will become due and may wish to take advice in advance on whether the instalment option will be available.

      They should also be exploring the different options that may be available to them to fund the IHT liability. Not doing so in a timely manner may prove costly in the future as from 6 April 2025 the interest rate on IHT paid late stands at the base rate plus 4 percent (totalling 8 percent at the time of writing). In many cases owners of private businesses are thinking about whether they may need to call on funds within the company. The impact this may have on the business’s own plans will require careful consideration.
