Inheritance Tax Changes From 2027: Should You Be Rethinking Your Home And Mortgage?
With unused pension wealth coming into the scope of Inheritance Tax from April 2027, some homeowners may need to look at their property, mortgage and wider estate as part of the same financial picture.
For many families, the family home is likely to be their largest asset. But for those with substantial pensions, investments and property, the way those assets are structured could become increasingly important as the Inheritance Tax rules change.
From 6 April 2027, most unused pension funds and pension death benefits will be brought within the value of an individual's estate for Inheritance Tax purposes. The government estimates that around 38,500 estates could pay more IHT as a result, with an average increase of around £34,000 for those affected.
That does not mean every homeowner needs to change their mortgage or property arrangements. But it does mean that some people may benefit from reviewing how their home fits into their wider estate planning.
Could your mortgage become part of the conversation?
A mortgage is already relevant when calculating the value of an estate. HMRC generally allows qualifying mortgage debt to be deducted from the value of the property against which it is secured.
This creates an important distinction between property value and net estate value.
For example, someone might own a £1.5 million home with a £500,000 mortgage. Their property asset is worth £1.5 million, but the outstanding mortgage affects the net value of their estate.
That does not mean taking out a mortgage is an effective way to reduce Inheritance Tax. Borrowing simply to create a liability can introduce interest costs, affordability considerations and other financial risks.
Instead, the important question is whether your existing mortgage still makes sense as part of your wider financial plan.
1. Review whether paying off the mortgage is still the right strategy
For many people approaching retirement, paying off the mortgage is an obvious financial goal.
But if your circumstances have changed, it is worth looking at the bigger picture rather than automatically prioritising mortgage repayment.
For example, you may have substantial pension assets, investments and property wealth. The 2027 changes mean the tax treatment of those assets on death may need to be considered together.
That could make questions such as these more relevant:
How much do you still owe on your mortgage?
When does your current mortgage deal end?
What are the early repayment charges?
Do you need to retain liquidity elsewhere?
What income will you need in retirement?
How might your pension and property interact within your estate?
The answer will be different for every household.
2. Consider whether downsizing still fits your plans
The family home can be particularly important for IHT planning because of the Residence Nil Rate Band (RNRB).
The RNRB is currently up to £175,000 per person where qualifying conditions are met, including passing a qualifying residence to direct descendants. It begins to taper for estates worth more than £2 million. Unused RNRB can also potentially be transferred between spouses or civil partners.
This means downsizing is not simply a lifestyle decision.
Moving from a large property to a smaller home could release capital, reduce mortgage commitments and potentially provide greater financial flexibility. But it can also affect how much of the RNRB is available.
There are specific downsizing rules that may allow the benefit to be preserved in certain circumstances, so it is important to understand the consequences before selling a family home.
3. Be careful about gifting your home
One option some homeowners consider is transferring their property, or part of it, to children during their lifetime.
However, this is not as straightforward as simply changing the name on the title.
Under the existing rules, if you give away your home but continue living there without paying the new owner a market rent, it can be treated as a gift with reservation of benefit and remain part of your estate for IHT purposes.
Where a genuine gift is made, the seven-year rule can also become relevant. Generally, if you survive seven years after making a qualifying gift, it falls outside the estate for IHT purposes, subject to the relevant rules and exemptions.
There can also be Capital Gains Tax, Stamp Duty Land Tax and other legal considerations depending on the circumstances.
In other words, gifting a property should never be treated as a simple IHT shortcut.
4. Look at your wider estate, not just your house
The biggest lesson from the 2027 reforms is that estate planning should not be carried out asset by asset.
Your home, pension, investments, cash and other assets all form part of the wider picture.
For example, someone may have historically prioritised keeping pension wealth invested because of its previous IHT treatment. From April 2027, that strategy may need to be reconsidered because most unused pension funds will generally be included within the estate.
That could make it worthwhile to review how retirement income is generated, which assets are used during retirement and what ultimately passes to beneficiaries.
5. Don't make a mortgage decision purely for tax reasons
Perhaps the most important point is that Inheritance Tax should not be the only reason to make a major property or borrowing decision.
Taking on debt, repaying debt, moving home or gifting property can all have significant financial consequences.
Instead, consider your objectives first.
Do you want to remain in your current home? Are you planning to downsize? Do you need additional capital? Are you approaching retirement? Do you want to help your children financially? How much income will you need? And how much of your wealth do you ultimately want to pass on?
These questions can help determine whether your mortgage and property strategy still supports your wider plans.
The 2027 changes are a reason to review, not panic
The introduction of the new pension rules does not mean every homeowner needs to restructure their finances.
But for families with substantial pensions, property or wider assets, 2027 is a useful deadline for reviewing the bigger picture.
Your mortgage is not simply a monthly payment. Your home is not simply an asset. And your pension is not simply a source of retirement income.
For many families, these pieces are interconnected.
Understanding how they fit together can help you make more informed decisions about borrowing, property, retirement and the wealth you ultimately pass on.
