Numbers make this clearer. Here's a simplified illustration of how an outstanding lifetime mortgage can change an IHT outcome.
These figures are illustrative only and do not constitute financial or tax advice. Individual circumstances vary. Always seek regulated advice for your specific situation.
| Property value | £600,000 |
| Other assets (savings, investments) | £50,000 |
| Gross estate | £650,000 |
| Available NRB + RNRB (individual) | £500,000 |
| Taxable amount | £150,000 |
| IHT at 40% | £60,000 |
(£150,000 lifetime mortgage outstanding)
| Property value | £600,000 |
| Other assets (savings, investments) | £50,000 |
| Gross estate | £650,000 |
| Less: lifetime mortgage debt | −£150,000 |
| Net estate | £500,000 |
| Available NRB + RNRB (individual) | £500,000 |
| Taxable amount | £0 |
| IHT at 40% | £0 |
In this example, the outstanding lifetime mortgage reduces the net estate from £650,000 to £500,000 — exactly in line with the available nil-rate band allowances. The result: an IHT bill of £60,000 becomes £0.
Of course, the picture changes if the released funds are still sitting in a savings account (adding back to the estate), or if the property value has grown significantly since the plan was taken out. This is why a personalised calculation — modelled by a specialist — is so important.
Equity release can form a useful part of an IHT strategy, but it's not a simple fix. Here are four situations where the picture becomes more complex:
As covered above: if released funds sit in a bank account, they remain part of your estate. The loan reduces the property side of the estate, but the cash adds it back. The net IHT benefit may be minimal unless the money is spent or gifted.
The longer a lifetime mortgage runs, the larger the outstanding balance becomes (because interest compounds). A larger loan means a greater deduction from the gross estate — which can be beneficial for IHT. However, it also means less equity remains for your beneficiaries to inherit. These two effects work in opposite directions, and the balance between them depends on how long you live and how much the property appreciates.
Releasing equity and holding the cash as savings can push your liquid assets above the thresholds for means-tested state benefits — including Pension Credit, Council Tax Reduction, and help with care costs. This is an indirect cost that IHT-focused planning can easily overlook.
Equity release advisers are specialists in the equity release product — they are not tax advisers. If your estate involves trusts, business assets, agricultural property, or multiple properties, the IHT implications require input from a qualified tax specialist or financial planner alongside your equity release advice.
Equity release is rarely the right choice if reducing inheritance tax is the only reason for taking it. The costs involved — primarily the compound interest that rolls up over the life of the plan — need to be weighed against the IHT saving you're likely to achieve.
When you take out a lifetime mortgage, the outstanding loan — including any interest that has rolled up — is registered as a secured debt against your property. For IHT purposes, HMRC calculates your net estate by deducting liabilities from your gross assets. Because the equity release loan is a debt, it is subtracted from your estate’s total value before any IHT calculation is applied. A larger outstanding balance means a lower net estate, which may bring the total below your available nil-rate band allowances — reducing or eliminating an IHT liability. The effect is most pronounced when released funds have been spent or gifted rather than retained as cash savings.
It can — but the outcome depends on what you do with the money. The loan itself reduces the net value of your estate, which is the figure HMRC uses to calculate IHT. If you spend the released funds on home improvements, living costs, or care, that reduction is straightforward. If you gift the money to family and survive for seven years, the gift falls outside your estate entirely under the Potentially Exempt Transfer rules. However, if you hold the released cash in savings, it remains part of your estate — offsetting much of the IHT benefit the loan creates. The most effective route is usually gifting combined with the seven-year rule, but this requires careful planning and ideally specialist tax advice alongside your equity release advice.
Every individual has a Nil-Rate Band (NRB) of £325,000 — the amount you can leave free of IHT. On top of this, if you leave your main home to direct descendants (children or grandchildren), you may also qualify for the Residence Nil-Rate Band (RNRB) of up to £175,000, bringing your personal threshold to up to £500,000. Married couples and civil partners can combine their allowances: if one partner dies without using their full NRB and RNRB, the unused portion passes to the survivor, potentially sheltering up to £1,000,000 as a couple. These thresholds are set by the government and can change — always confirm current figures with HMRC or a qualified adviser before making any decisions.
When you die, the outstanding lifetime mortgage — the original loan plus all rolled-up interest — is repaid from the proceeds of selling your home. Crucially, this repayment happens before the remaining estate is distributed to your beneficiaries. From an IHT perspective, this is significant: the loan and interest are deducted from the gross estate value when HMRC calculates what tax is owed. In other words, the repayment of the equity release debt directly reduces the net taxable estate. Your family will never be asked to repay more than the property sells for — the No Negative Equity Guarantee ensures the lender cannot pursue other estate assets if the sale proceeds fall short of the outstanding balance.
Yes — and it’s important to understand that these are two distinct roles. An equity release adviser (like ours, FCA Ref 816029) is a specialist in finding the right lifetime mortgage or home reversion plan for your circumstances. They will assess your eligibility, compare plans across the whole of the market, and ensure the product is suitable for you. However, IHT planning — particularly if it involves gifting strategies, trust structures, complex estates, or business assets — sits within the domain of a qualified tax specialist or financial planner. The two types of advice complement each other well, and for most people considering equity release as part of an estate plan, both conversations are worth having. We’re happy to point you in the right direction.
