Taper relief is one of the most misunderstood rules in inheritance tax planning. Most people believe it gradually reduces the value of a gift over seven years. It does not. It reduces the rate of tax — and only on amounts above the nil-rate band.
Here is how the sliding scale works: gifts made 0 to 3 years before death are taxed at the full 40%. Between 3 and 4 years, the rate drops to 32%. Between 4 and 5 years, 24%. Between 5 and 6 years, 16%. Between 6 and 7 years, just 8%. After seven years, the gift is completely exempt.
The critical detail most families miss is that taper relief only kicks in once your cumulative gifts exceed the £325,000 nil-rate band. If your total gifts in the seven years before death stay below £325,000, there is no tax to taper — the nil-rate band covers everything, and taper relief is irrelevant.
Consider a practical example: you give away £525,000 and die four and a half years later. The first £325,000 is covered by your nil-rate band. The remaining £200,000 is taxed at 24% (the taper relief rate for 4-5 years) instead of 40% — a saving of £32,000. But your estate loses access to the nil-rate band entirely, meaning everything else is taxed from the first pound.
The five most common mistakes families make: assuming taper relief reduces the gift value (it does not), forgetting the nil-rate band comes first, failing to keep records of every gift, making gifts with reservation of benefit (where you continue to use the asset), and ignoring the cumulative impact on the nil-rate band available for the rest of the estate.
The practical steps that matter most: start giving early, use annual exemptions of £3,000 per person first, keep detailed records of every gift with dates and amounts, take professional advice before large transfers or gifts into trusts, and review your plan regularly as circumstances change.
With the nil-rate band frozen at £325,000 until at least 2030 and asset values continuing to grow, more families are being pulled into the taper relief calculation every year. The seven-year clock starts on the day you make the gift — every year you wait is a year lost.
