Why it matters
What Inheritance Tax (IHT) means for a landlord
A buy-to-let portfolio is often the biggest driver of an IHT bill because property values are high and, unlike a business, a rental portfolio does not usually qualify for Business Property Relief. Landlords sometimes incorporate into a limited company or use trusts for succession planning, but each route has its own CGT, SDLT and ongoing-cost consequences and needs specialist advice. Thresholds and reliefs change at fiscal events, so any figure here should be confirmed against current GOV.UK guidance before you plan around it.
Worked example
How it plays out
Brian dies owning his home and two buy-to-let flats worth £450,000, with £150,000 of mortgages on them. The flats add £300,000 to his estate. His estate is over the tax-free threshold, so part of it is taxed at 40%, and his executors may need to sell a flat to pay.
Common mistakes
Where landlords go wrong
