When your home is your biggest asset, inheritance tax planning looks different.
For a growing number of UK families, property is the biggest thing they own. House prices have risen sharply while tax thresholds have stayed frozen, and the result is that many people face an inheritance tax bill driven mainly by the value of their home.
The core problem is simple. Inheritance tax is worked out on what your estate is worth, but it has to be paid in cash. If your estate is worth £1.5 million and most of that is your house, you could owe £200,000 or more in tax — and HMRC will want at least some of it paid before your family can deal with the property. That can force a sale of the family home just to pay the bill.
If your main home passes to your children, stepchildren, adopted children, foster children, or grandchildren, you qualify for an additional tax-free allowance of £175,000 on top of the standard £325,000 nil-rate band. For a married couple or civil partnership, that is up to £350,000 extra — potentially bringing the total tax-free amount to £1,000,000.
This is one of the most valuable allowances available, but it only applies when the home passes to direct descendants. If you leave the property to a brother, sister, friend, or anyone else, the extra allowance does not apply.
The £2 million trap. If your total estate is worth more than £2 million, the residence nil-rate band starts to shrink. You lose £1 of the allowance for every £2 your estate is above the threshold. A valuable home can easily push you past this mark — especially when you add pensions, savings, and investments on top. In the range where the allowance is being reduced, the real tax rate is 60%, not 40%.
If you own your home with a spouse or partner, there are two ways it can be held. Joint tenants means the property passes automatically to the survivor when one of you dies — simple, but it concentrates everything in one name. Tenants in common means each person owns a defined share (usually half) and can leave their share to whoever they choose in their will.
Switching from joint tenants to tenants in common is one of the most common and effective steps in inheritance tax planning. It allows each spouse to leave their share directly to children (or into a trust for them), which can preserve tax-free allowances and take value out of the estate at the first death rather than letting everything build up for the second.
This is a legal change handled by a solicitor. It does not affect who lives in the property or how you use it day to day.
This is one of the most searched questions about inheritance tax — and the answer is: yes, but with a very important catch.
If you give your home to your children but continue living in it without paying a proper market rent, HMRC treats it as though you never gave it away. The property stays in your estate and the gift has no effect on your inheritance tax bill. This is called a "gift with reservation of benefit" and it is one of the most common planning mistakes.
For the gift to work, you would need to either move out completely or pay your children a fair market rent to continue living there. There may also be capital gains tax to pay on the transfer. This is an area where professional advice is essential before doing anything.
Worth knowing. The question "can I give my house to my children to avoid inheritance tax?" is asked thousands of times a month. The honest answer is that it is rarely as simple as it sounds. There are legitimate ways to reduce the inheritance tax impact of property, but they usually involve changing how the property is owned and passed through your will — not giving it away outright.
Investment properties are included in your estate at their full market value, just like your main home. However, investment properties do not qualify for the residence nil-rate band — that extra allowance only applies to the home you lived in.
The ownership structure, whether to hold property through a company, the interaction with capital gains tax, and how to plan succession for investment property all require specialist attention. If you own rental properties or a portfolio of buy-to-lets, this is one of the areas where coordinated advice from a financial planner, solicitor, and tax adviser makes the biggest difference.
If you are based in the UK, your worldwide property is included in your estate for inheritance tax purposes — including holiday homes and investment property overseas. Some countries also charge their own inheritance tax on property located in their territory, which can create a double taxation situation. The UK has double taxation treaties with some countries (but not all) to address this.
Selling a large home and moving to something smaller releases cash that can be gifted, spent, or used for other planning. If the home is the main reason your estate exceeds the £2 million threshold, downsizing can restore the full residence nil-rate band — a saving of up to £140,000 in tax for a couple.
There are also "downsizing rules" that protect the residence nil-rate band if you sell your home before death. As long as the equivalent value passes to direct descendants through your will, the allowance can still apply. This is a technical area that usually needs a solicitor to set up correctly.
If your family wants to keep the property, there are ways to fund the inheritance tax bill without selling. Whole-of-life insurance written in trust can provide a lump sum specifically to cover the tax. HMRC also allows inheritance tax on property to be paid in annual instalments over ten years, which gives the family time to arrange their finances — though interest is charged on the outstanding balance.
