Inheritance Tax on Property UK: How Every Type of Property Is Taxed (2026)
Property is typically the largest asset in a UK estate — and different types of property have very different IHT treatment. The main home may qualify for the RNRB (saving up to £70,000). Farmland may attract 100% APR. But buy-to-let, second homes, and most commercial property have no IHT relief at all. Here is how every property type is taxed.
| Property Type | In Estate? | IHT Relief? | Instalment Option? | Key Notes |
|---|---|---|---|---|
| Main home (to direct descendants) | Yes (net of mortgage) | RNRB up to £175k | Yes (s227) | Will must direct home to children/grandchildren — not a discretionary trust |
| Main home (not to direct descendants) | Yes (net of mortgage) | None | Yes (s227) | RNRB lost — home to sibling, trust, or non-descendant |
| Buy-to-let / investment property | Yes (full market value) | None | Yes (s227) | Mortgage deductible. Loss on sale relief (s191) within 4yr. |
| Second home / holiday property | Yes (full market value) | None | Yes (s227) | FHLs may argue BPR if significant services — uncertain. |
| Agricultural land (owner-occupied, 2yr+) | Yes — at agricultural value | 100% APR (£1m cap from Apr 2026) | Yes (s227) | Farmhouse also qualifying if character appropriate. |
| Agricultural land (let, 7yr+ tenancy) | Yes — at agricultural value | 100% APR (most post-1995 tenancies) | Yes | 50% APR for some older tenancy arrangements. |
| Development land / planning uplift | Yes (full market value) | APR on agricultural value only | Yes | Planning uplift is not covered by APR — taxable at 40%. |
| Jointly tenanted property (first death) | No — survivorship | N/A | N/A | Passes outside will to surviving co-owner. In estate on second death. |
| Tenants in common — deceased's share | Yes — deceased's share only | RNRB if share passes to descendants | Yes | Valuation discount (10–15%) may apply to minority share. |
| Property in discretionary trust | In trust — not in estate | Periodic/exit charges (up to 6%) | N/A | RNRB lost if home in NRB discretionary trust. |
2026/27 figures. RNRB £175,000; tapers for estates above £2m. APR/BPR £1m combined cap from April 2026. Instalment option: 10 equal annual payments; interest 7.25% pa on balance. Loss on sale relief (s191) must be claimed within 4yr of death.
IHT on Property: Detailed Guide
The main home — RNRB and the importance of the will
The main home (primary residence) is in the IHT estate at its open market value at the date of death, less any outstanding mortgage. The mortgage is a liability deducted under s5 IHTA 1984. The Residence Nil-Rate Band (RNRB — s8D IHTA 1984) adds up to £175,000 to the effective IHT threshold where the home (or a proportion of it) passes to direct descendants: children, grandchildren, stepchildren, adopted children, and their lineal descendants. This means: if the home is worth £600,000 with a £150,000 mortgage, it contributes £450,000 net to the estate. If the will leaves the home to children, £175,000 of that net value is covered by the RNRB — reducing the taxable amount by £175,000, saving £70,000 in IHT. Critical: the RNRB is ONLY available where the home passes to direct descendants under the will or intestacy. If the home passes to a sibling, a discretionary trust, a friend, or a charity — the RNRB is lost. The RNRB is also tapered for estates above £2,000,000 (fully lost at £2,350,000 for a single person). Downsizing addition (s8FA IHTA 1984): where the deceased sold or downsized a home after 8 July 2015, and left other assets to direct descendants, the RNRB may still be claimable — even though the home is no longer in the estate at death.
Buy-to-let and investment property
Buy-to-let (BTL) and investment properties are in the IHT estate at their full open market value at the date of death: (1) No RNRB: the RNRB applies only to the main home passing to direct descendants — BTL properties do not qualify; (2) No BPR: property let out under assured shorthold tenancies or other residential tenancy agreements is an investment activity (not a trade) — it fails the BPR trading test. Commercial property let to tenants is also generally investment rather than trading (unless the landowner provides significant active services); (3) The mortgage is deductible: outstanding BTL mortgages reduce the estate value under s5 IHTA 1984; however, the s103 Finance Act 1986 anti-avoidance rule prevents the deduction of liabilities where the cash borrowed was used to acquire an exempt or relievable asset and the liability has been artificially arranged; (4) Instalment option: IHT on BTL property can be paid in 10 annual instalments (s227 IHTA 1984) if the executors elect for this — important where a large property portfolio represents most of the estate's value; (5) Loss on sale: if a BTL property is sold within 4 years of death at below the probate value, the executor can claim a refund of the IHT overpaid (s191 IHTA 1984).
Second homes, holiday properties, and furnished holiday lets
Second homes (weekend homes, holiday properties) are in the estate at full market value with no IHT reliefs: (1) No RNRB — only the main home qualifies; (2) No BPR — owning a holiday property for personal use or letting it commercially is not a qualifying business for BPR; (3) Furnished Holiday Lets (FHLs): furnished holiday let properties that meet HMRC's FHL conditions (available to let 210 days/year, actually let 105 days/year, to the public) may have previously been argued to qualify for BPR as a trading activity. HMRC and the courts have increasingly taken the view that FHLs do not qualify for BPR unless significant additional services (cleaning, meals, concierge) are provided — broadly equivalent to a hotel or guest house. The IHT position on FHLs is uncertain and fact-specific; (4) Overseas holiday properties: if the deceased was UK-domiciled (or deemed UK-domiciled — s6 IHTA 1984), overseas property is in the estate and fully IHT-chargeable at UK rates. No exemption for foreign holiday homes.
Farmland and agricultural property — APR
Agricultural Property Relief (APR — ss115-124 IHTA 1984) reduces the IHT value of qualifying agricultural property. The relief rates: 100% APR: land and farmhouses where the deceased occupied the property for agricultural purposes for at least 2 years before death (owner-occupied). The farmhouse must be 'of a character appropriate to the property' (the character test); 50% APR: agricultural property that was let to a tenant at arm's length for at least 7 years (prior to 1 September 1995 — some pre-1995 tenancies still at 50%; most post-1995 tenancies at 100%); in practice, most let farmland now qualifies at 100% under the post-1995 rules. From April 2026 (Budget 2024): combined APR and BPR cap of £1,000,000 at 100%; 50% on qualifying agricultural property above the £1m cap (effective 20% IHT). Development land: APR applies to the agricultural value of land — it does NOT cover any uplift in value attributable to development potential or planning permission. Development hope value (the uplift from expected planning) is fully chargeable to IHT at 40%.
Jointly-owned property: joint tenants vs tenants in common
The IHT treatment of jointly-owned property depends on the type of co-ownership: (1) Joint tenants: on the first co-owner's death, the property passes automatically to the surviving co-owner(s) by right of survivorship — outside the will and outside the estate for IHT on the first death. The full property is in the surviving owner's estate on the second death; (2) Tenants in common: the deceased's specific share is in their estate — it passes under the will (or intestacy). The share is valued at market value (typically with a minority discount of 10-15% if a fraction of the whole property). IHT planning with jointly-owned property: severing a joint tenancy converts to tenants in common — the first death's share can then be directed to children in the will (claiming the RNRB on the first death) or into an NRB trust (using the NRB on the first death rather than relying entirely on the spousal exemption and transferred NRB).
Instalment option and loss on sale relief
Two important property-specific IHT provisions: (1) Instalment option (s227-229 IHTA 1984): where a significant IHT bill arises on property and payment in full would require a forced sale, the executor can elect to pay IHT in 10 equal annual instalments. The first instalment is due by the normal 6-month deadline. Interest is charged on the outstanding balance at HMRC's standard interest rate (7.25% currently). If the property is sold before all instalments are paid, the remaining balance falls due immediately. This is particularly important for estates where the main asset is property (a farming estate, a residential property portfolio, or a valuable family home); (2) Loss on sale of land relief (s191 IHTA 1984): if property in the estate is sold within 4 years of death at below the probate value, the personal representatives can claim to substitute the sale price for the probate value for IHT purposes — effectively claiming an IHT refund on the amount by which the probate value exceeded the sale price. This avoids the situation where IHT is paid on a valuation higher than what the property actually achieves on sale. The claim must be made within 4 years of death and 7 years of the grant of probate.
Frequently Asked Questions
Does property have to be included in inheritance tax?
Yes — all property owned by the deceased at death is included in the IHT estate at open market value, less any outstanding mortgage. This includes the main home, buy-to-let properties, second homes, commercial property, land, and overseas property (for UK-domiciled persons). The RNRB (up to £175,000) reduces the IHT on the main home if it passes to direct descendants. Agricultural property may qualify for APR (100% or 50%). Business property used in a qualifying trade may qualify for BPR (100% or 50%, up to the £1m combined cap from April 2026).
Do you pay inheritance tax on a house?
The house is included in the IHT estate at market value, less any mortgage. Whether IHT is actually paid depends on the total estate value: if the estate is below the NRB (£325,000) — no IHT. If the home passes to children and the estate is below the NRB + RNRB (£500,000 for a single person) — no IHT. If the estate exceeds the threshold — IHT at 40% on the excess. Example: estate £650,000, home £400,000 (to children), NRB £325,000, RNRB £175,000 — taxable estate £150,000 — IHT £60,000.
Is buy-to-let property exempt from inheritance tax?
No — buy-to-let property is in the IHT estate at full market value with no exemptions. BPR does not apply (property letting is investment, not trading). The RNRB does not apply. APR does not apply (not agricultural). The mortgage is deductible. The instalment option (s227 IHTA 1984) can spread the IHT bill over 10 years. Loss on sale relief (s191) may reduce the IHT if the property is sold within 4 years of death below the probate value.
Can I give my house to my children to avoid inheritance tax?
You can give your home to your children, but two issues arise: (1) Gift with reservation (s102 FA1986): if you give the home to children but continue to live in it rent-free, the home remains in your estate for IHT as if the gift was never made. To avoid this: pay a full market rent after the gift; (2) Capital Gains Tax: giving a home that is not your main residence (or where private residence relief doesn't cover the full gain) may trigger CGT on the increase in value. If the gift is structured correctly (you move out, or pay market rent), the home is a PET — IHT-free after 7 years. The RNRB is still claimable if the home passes directly to children on death, or via a correctly structured trust.
Is agricultural land exempt from inheritance tax?
Qualifying agricultural land can attract Agricultural Property Relief (APR — ss115-124 IHTA 1984): 100% APR for owner-occupied agricultural land (farmed by the deceased for 2+ years before death); 50% APR for let agricultural land (7+ years' tenancy). The farmhouse may also qualify for APR if it is 'of a character appropriate to the property' (the character test). From April 2026: combined APR + BPR cap of £1,000,000 at 100%; 50% on qualifying value above £1m (effective 20% IHT). Development potential (planning uplift) is NOT covered by APR — only the agricultural value is relieved.
Claim the RNRB — Direct Your Home to Children in Your Will
The RNRB saves up to £70,000 in IHT per person — but only where the will directs the main home to direct descendants. A will that leaves the home to the wrong person, or to a discretionary trust, loses the RNRB entirely. WillSafe will kits for England and Wales make this easy.
