With frozen allowances, upcoming changes to legislation around pensions and business relief, this upward trend is expected to continue, and a lot of estates are now giving rise to a liability where there was previously none.
The important point to remember here is that we can plan for IHT and there are strategies with varying levels of access, control, cost and complexity but there are options available to you.
IHT may arise on your estate, normally at a rate of 40%, if your estate exceeds the allowances available. How this liability is met can be a source of great stress for executors especially if a large portion of your wealth is illiquid through property holdings. It is important a clear and established plan is communicated intergenerationally to ensure that your legacy is secured.
The following are the main allowances that can be used to offset against your estate for IHT purposes.
Spousal exemption – if you are married or in a civil partnership, you can pass any asset to your spouse without tax implications which includes receiving assets on death. There are no cohabitation rights for couples that are unmarried/not civil partners regardless of the length of your relationship so keep this in mind for continuity planning.
Nil rate band (NRB) – we each have a nil rate band of £325,000 per person which can be offset against the value of your estate. If your estate is below this value, no IHT will be due.
The caveat to be aware of here is any non-exempt financial gifts you have made will deplete your nil rate band first until they fall outside of your estate after seven years. For example, if you made a non-exempt gift of £50,000, your nil rate band would reduce to £275,000 for the next seven years.
Residence nil rate band (RNRB) – this allowance can be offset against the value of a property that has ever been your main residence value up to the lesser of, the total value of the property and £175,000 provided the property is passed to a direct descendant. This includes children, grandchildren, step-children, foster children and children where you have been appointed by a court order as a guardian, or special guardian if that appointment took effect when the child was under the age of 18. For clarity, if your house is worth £100,000 you will only benefit from an allowance of £100,000. If it is worth £600,000 you will only benefit from an allowance of £175,000.
If you do not have any direct descendants, your estate cannot benefit from this allowance. If you are cohabiting (i.e. unmarried/not civil partners) and you pass your residual share of your property to your partner on death, again, your estate cannot benefit from this allowance. If your estate exceeds £2million, then this allowance reduces by £1 for every £2 of estate above £2 million.
Provided you are eligible for these allowances, this gives you a total of £500,000 to offset against IHT or £1 million per couple if married or in a civil partnership.
Through both the nil rate band allowance being frozen since 2009/2010 and increasing asset values, particularly in property, this is becoming an increasingly common issue.
More and more estates are being caught by IHT through fiscal drag and you may be impacted when you previously haven’t been, potentially putting your legacy at risk.
There is the view that IHT is unnecessarily complex and contentious with some estates being able to benefit from an additional allowance if they have children. Although this could promote intergenerational planning, with modern day family complexities, coupled with lack of cohabitee rights when passing assets to one another, the rules feel outdated.
Could it be modernised and simplified? Absolutely but with frozen allowances, those falling into the IHT trap will continue to grow.
