Imagine you’ve spent decades in your family home, raising kids, building memories, and watching its value climb steadily over the years. Now, as retirement approaches, you’re thinking about moving to something smaller, more manageable – or perhaps even selling up to cover care costs. A nagging worry creeps in: will this decision shrink the tax-free amount you can pass on to your loved ones? It’s a question I’ve heard from so many people over the years, and understandably so – no one wants to unintentionally hand more over to the taxman than necessary.
The good news is that there’s a specific provision designed exactly for situations like this. It’s not shouted about as much as it should be, which means plenty of families end up paying more inheritance tax than they need to. In this guide, I’ll walk you through how it all works, with practical examples and tips to make sure you don’t miss out.
Protecting Your Inheritance Tax Relief When You Move
At its core, the concern revolves around something called the residence nil rate band – an extra tax-free allowance specifically tied to passing on your home. Without it, you might feel stuck in a larger property just to preserve the full benefit. But the rules have evolved to address exactly that dilemma, allowing flexibility without penalty.
Understanding the Basic Inheritance Tax Thresholds
Let’s start with the fundamentals, because everything else builds on this. Most people know there’s a standard tax-free allowance – currently £325,000 per person. Anything above that in your estate could face a 40% tax bill when you pass away.
On top of that, there’s an additional allowance if you’re leaving a home to your direct descendants. This can boost the tax-free threshold to £500,000 for an individual, or a full £1 million for a married couple if both allowances are combined and transferred properly. It’s a significant difference – potentially saving £200,000 in tax for a couple.
But here’s where it gets tricky. The extra allowance is linked to the value of the home you own when you die. If you’ve already sold the larger property and moved into something cheaper, does that mean you lose part of this valuable relief? Not necessarily.
Who Can Claim the Residence Nil Rate Band?
Not everyone qualifies automatically, so it’s worth checking the criteria early. First, the rules only apply if you passed away on or after 6 April 2017. The property must have been your residence at some point – investment properties or buy-to-lets don’t count.
Crucially, the home (or its equivalent value) needs to go to direct descendants: children, grandchildren, step-children, or adopted children. Leaving it to nieces, nephews, siblings, or friends means the extra allowance disappears entirely.
- You must have owned and lived in the property at some stage
- It must pass to lineal descendants
- Estates over £2 million see the allowance gradually reduced
- From 2027, certain pension changes might affect more people
In my experience, one common question arises when people have owned multiple homes they’ve lived in. Which one counts? The answer is that executors can choose the most advantageous – usually the higher-value one – but you can’t double up.
The Downsizing Relief Explained
This is the part that addresses the main worry. Sometimes called the “downsizing addition,” it ensures you don’t lose the full residence allowance just because you moved to a smaller place or sold up entirely.
The thinking behind it makes perfect sense. Policymakers didn’t want people staying in oversized homes purely for tax reasons when a smaller property would suit their needs better – or when selling was necessary to fund care. That would just block larger homes from younger families while creating unnecessary stress for older owners.
The relief recognises that life changes, and tax rules shouldn’t force people to stay put against their wishes.
Importantly, there’s no judgment on why you’re moving. Whether it’s to release equity, simplify life, be closer to family, or fund residential care, the protection still applies – provided certain conditions are met.
How the Relief Works in Practice
Let’s look at a typical scenario to make this clearer. Suppose a widow owns a house worth £600,000. She decides to sell and move into a flat valued at £300,000, using the remaining proceeds for retirement comforts.
Without any special rules, her estate would only qualify for residence relief based on the £300,000 flat – meaning she’d lose half the potential allowance. But with downsizing relief, executors can claim the “lost” portion based on the former home’s value.
The calculation essentially asks: what would the residence allowance have been if she still owned the original property? Then it bridges the gap between that figure and what’s available from the new, smaller asset.
- Establish the value of the former home (or its sale proceeds)
- Compare to the maximum residence allowance (£175,000 per person)
- Calculate any shortfall from the current property
- Add the difference as extra relief, up to the lost amount
Even if you no longer own any property at all – perhaps because the house was sold to pay care fees – the relief can still apply. The key is that equivalent assets (savings, investments from the sale) are passed to direct descendants.
Real-Life Examples That Bring It to Life
Consider a couple who sold their £800,000 family home five years ago and downsized to a £400,000 bungalow. Their total estate now stands at £1.2 million, including investments.
Had they kept the original house, their combined residence allowances would cover £350,000 tax-free on top of the standard £650,000 nil rate bands. With the smaller property, they might initially qualify for less – but the relief tops it back up to the full amount, potentially eliminating any inheritance tax liability altogether.
Another common situation involves care costs. An elderly parent moves into residential care and sells the family home to fund it. Many children fear this wipes out the residence allowance completely. Yet as long as the remaining assets (after legitimate care expenses) go to direct descendants, the full relief remains claimable based on the former home’s value.
It’s not about punishing people for making practical decisions later in life – it’s about fairness across different circumstances.

Common Pitfalls to Avoid
Perhaps the biggest risk is simply not knowing about the relief. It’s not applied automatically – executors must claim it specifically when submitting inheritance tax forms.
Some solicitors handle this routinely, but others might need prompting. I’ve seen cases where families paid thousands extra simply because the paperwork didn’t reference the former property value.
- Gifting the home or proceeds to non-qualifying beneficiaries
- Placing assets in certain types of trusts that break the direct descendant rule
- Failing to keep proper records of the sale and how proceeds were used
- Assuming the relief applies regardless of estate size (remember the £2 million taper)
Timing matters too. The move or sale must have happened on or after 8 July 2015 to qualify under current rules.
Essential Record-Keeping Tips
When the time comes, your executors will need solid evidence to support any claim. This isn’t about distrust – it’s just how the system works to prevent abuse.
Start gathering documentation early, rather than leaving it to grieving relatives to scramble for paperwork. Simple steps now can save considerable stress later.
| Document Type | Why It Matters |
| Sale completion statement | Proves date and value of former home |
| Bank statements | Tracks use of proceeds |
| Current property valuation | Establishes baseline for calculation |
| Will and estate plans | Confirms beneficiaries qualify |
| Care fee invoices (if applicable) | Explains expenditure of proceeds |
Digital copies are fine, but keep originals safe too. A dedicated folder – physical or electronic – labelled clearly makes everything much smoother.
Planning Ahead Makes All the Difference
The most effective approach is to review your situation before making any big moves. A conversation with a qualified adviser can highlight opportunities and risks specific to your circumstances.
For instance, sometimes structuring how proceeds are held or invested can preserve more flexibility. Other times, it’s about ensuring your will reflects the qualifying beneficiary rules perfectly.
Don’t wait until after the sale – by then, some options might be limited. Early planning often reveals ways to maximise both your quality of life and your family’s eventual inheritance.
In the end, these rules exist to support practical decisions without tax penalties. Understanding them removes the fear that downsizing or funding care will cost your children dearly. With proper awareness and preparation, you can make choices based on what suits you best – secure in knowing the tax relief follows the value, not just the bricks and mortar.
It’s one of those areas where a little knowledge goes a very long way. And in my view, that’s exactly how inheritance planning should be – empowering rather than restrictive.
