How much can you give away to reduce Inheritance Tax? It is one of the most common questions in UK estate planning, and the answer most people carry around is wrong.

The popular version goes like this: give money away, survive seven years, and it escapes tax. Live for only part of that time, and taper relief means the gift is taxed at a gently reducing rate the longer you last.

That second half is where nearly everyone goes astray. Taper relief is real, but it does something narrower than most people think, and for ordinary-sized gifts it often does nothing at all. If you are going to use gifting as a lever, it is worth understanding exactly what the rules reward.

Why gifting is a sharper lever than it used to be

Inheritance Tax (IHT) is charged at 40% on the value of your estate above your available allowances.

Everyone gets a nil-rate band of £325,000. On top of that sits a residence nil-rate band of up to £175,000 where you leave a main home to your children or grandchildren. Both are frozen, currently until April 2031, which means that as house prices and portfolios grow, more families cross the line every year without ever feeling wealthier.

Then comes a bigger shift. From 6 April 2027, most unused pension pots will count as part of your estate for Inheritance Tax, where today they usually sit outside it. (Who actually inherits your pension, and how your expression of wish directs it, is a separate question worth its own look.) The combined effect is simple: more estates are being pulled into the 40% band by frozen thresholds and by pensions joining the calculation.

That is why lifetime gifting has become a sharper tool. It is one of the few remaining levers that can genuinely move an IHT bill, and understanding it properly is exactly the kind of estate-and-retirement modelling Optiml UK is being built to handle.

What the 7-year rule actually is

Most gifts you make to another person are called a potentially exempt transfer, or PET.

The word "potentially" is doing the work. A PET is not taxed when you make it. If you survive seven years from the date of the gift, it falls completely outside your estate and there is no IHT to pay on it. Full stop.

If you pass away within those seven years, the gift is brought back into your IHT calculation as though you still held it. That survival period is the 7-year rule. There is no cap on the size of a PET, which is what makes it powerful for larger transfers, and also what makes the seven-year clock matter so much.

The taper relief misconception, corrected

Here is the part almost every article gets wrong.

Taper relief reduces the tax due on a gift, and it only applies where the gifts made in the seven years before you pass away exceed the £325,000 nil-rate band. If your gifts sit within the nil-rate band, there is no tax to taper in the first place. The band covers them.

So taper relief is not "the whole gift gets taxed at a lower rate the longer you survive." For most people making normal-sized gifts, taper never bites at all, because the tax it would reduce is zero. It only reaches the portion of gifts above £325,000, and only when someone passes away between three and seven years after making them.

When it does apply, this is the schedule. Read it as a reduction to the tax on the slice of gifts above the nil-rate band, not to the value of the gift itself.

One more detail that trips people up: a gift within the nil-rate band is not taxed, but it still uses up that band for the rest of your estate. So a gift can be "tax-free" on its own and still increase the tax on everything else you leave behind if you pass away within seven years.

The gifts that carry no 7-year clock at all

Here is the good news the seven-year rule tends to overshadow. Several gifts are immediately exempt. No clock, no seven-year wait, no bringing them back. These are valuable and badly under-used.

• Annual exemption: £3,000 of gifts each tax year, completely outside your estate. You can carry forward one unused year, so up to £6,000 if you missed last year.
• Small gifts: up to £250 per person, per tax year, to as many different people as you like. You cannot combine this with the annual exemption to the same person.
• Normal expenditure out of income: regular gifts made from your surplus income, not your capital, that do not affect your standard of living. Done properly and evidenced, these can be exempt with no upper limit. This is one of the most powerful and least-used exemptions in the system.
• Wedding gifts: £5,000 to a child, £2,500 to a grandchild, £1,000 to anyone else.
• Spouse, civil partner and charity: gifts to your husband, wife or civil partner, and gifts to charity, are fully exempt.

The normal-expenditure-out-of-income exemption deserves a second look. If you have more pension and investment income than you spend, a regular pattern of gifts from that surplus can leave your estate immediately, year after year, without ever touching the seven-year clock. The catch is evidence: keep clear records of your income, your outgoings, and the gifts, so the pattern is provable later.

The trap: gifts with reservation of benefit

There is one mistake that quietly undoes an otherwise sensible plan.

If you give something away but carry on benefiting from it, HMRC treats it as though you never gave it away. The classic example is signing your house over to your children while continuing to live in it rent-free. That is a gift with reservation of benefit, and the seven-year clock does not save you. The property stays inside your estate for IHT.

The rules around the family home, and anything involving trusts, are genuinely complex, and this is where do-it-yourself planning goes wrong most often.

A worked illustration

Consider Elaine, 74, a widow in England with an estate comfortably over her allowances. She wants to help her granddaughter and reduce what her estate will owe. She weighs two approaches.

Approach one: use the exemptions. Elaine gives £3,000 a year under her annual exemption, and adds regular gifts out of her surplus pension income on top. Every pound leaves her estate the moment she gives it. There is no seven-year wait, no risk of the gift being clawed back, and nothing to taper. The trade-off is pace: this chips away at the estate steadily rather than in one move.

Approach two: one large gift. Instead, Elaine gifts £400,000 in a single transfer. This is a PET. If she survives seven years, the whole £400,000 is outside her estate and there is no IHT on it. If she passes away sooner, the gift is brought back. The first £325,000 is covered by her nil-rate band, leaving £75,000 taxable, and taper relief applies only to the tax on that £75,000 slice.

Here is how the tax on that gift moves with time, if she passes away before the seven years are up.

Notice what taper is and is not doing. It never touches the first £325,000 of the gift, because the nil-rate band already covers it. It only softens the tax on the £75,000 above the band, and only from year three onward. The exemptions in approach one, by contrast, work from day one and never depend on how long anyone survives.

Neither approach is automatically "better." A single large gift can move far more out of an estate, faster, if the survival odds are reasonable. The steady exemptions are certain but slow. The right balance depends on your age, your health, your income surplus, and, above all, on whether you can afford to give the money away without denting your own retirement. These figures are illustrative, on stated 2026/27 assumptions, and rates differ in Scotland for the income side of the picture.

Where this fits, and where to be careful

Gifting is one of the few big levers left on an IHT bill. But it never stands alone.

It interacts with your own retirement security, and the first rule is the one no calculator can enforce for you: never give away money you might need. It interacts with the reservation-of-benefit rules, which can quietly cancel the benefit you thought you had bought. And it leans heavily on record-keeping, especially for gifts out of income, where the evidence is what makes the exemption stand up.

Larger estates, anything involving trusts, and any plan touching the family home genuinely need professional advice from a solicitor or estate planner. This article is education, not a recommendation to make any particular gift.

What software can do is show you the whole board at once. How your gifts, your frozen nil-rate bands, your pension (inside the estate from April 2027) and the rest of your assets combine to shape what your heirs actually keep, and whether a gift leaves you short in your own later years. That whole-picture estate-and-retirement modelling is exactly what we are building for the UK. Optiml is coming to the UK, and the waitlist is where to be first in line.

The 7-year rule rewards understanding, not guesswork. Taper relief is not the escape hatch it is sold as, and the immediate exemptions are the quiet workhorses most people leave on the table.

It's not about surviving a clock. It's about giving with your eyes open.
