Inheritance Tax (IHT) is the tax most often misunderstood by property landlords. The headline 40% rate above the £325,000 nil-rate band catches the attention; the loss of all the meaningful reliefs (no BPR for rentals, no Agricultural Property Relief for residential, no APR-style exemptions for standard buy-to-let) is what bites in practice. For a typical Harrow landlord with £1.5m of property and £200,000 of other estate, an unplanned death triggers IHT of £400,000-£500,000, due within 6 months and often forcing forced asset sales.
IHT planning works on a 7-15 year time horizon. The earlier the planning starts, the more options remain. This guide covers the core mechanics: thresholds, gifting, FICs vs trusts, the BPR myth, joint-investor protection, profit extraction, and retirement-restructure decisions.
IHT thresholds and 2026 changes
- Nil-rate band: £325,000 per individual (frozen until April 2028).
- Residence nil-rate band: £175,000 where a main residence is left to direct descendants. Tapers above £2m of total estate.
- Combined nil-rate band for a married couple/civil partnership: up to £1m where both rates are unused and transferable.
- Standard IHT rate: 40% above the nil-rate band.
- Reduced rate: 36% where 10% or more of the net estate is left to charity.
The £2m taper destroys the residence nil-rate band fast
For estates above £2m, the residence nil-rate band tapers down at £1 for every £2 of excess. By £2.35m, the residence nil-rate band is gone entirely. Many Harrow landlords with property values plus pension and savings cross £2m without realising.
Family Investment Companies vs trusts
The two main wealth-transfer wrappers for property portfolios:
FIC vs Discretionary Trust for property wealth transfer
| Aspect | Family Investment Company (FIC) | Discretionary Trust |
|---|---|---|
| Setup cost | £3,000-£8,000 | £2,500-£5,000 |
| Annual running cost | £2,000-£3,500 | £1,200-£2,500 |
| Lifetime IHT entry charge | None (FIC is a company, not a transfer) | 20% on value above nil-rate band |
| 10-yearly IHT charge | None | Up to 6% |
| Periodic exit charge | None | Up to 6% |
| Tax on income | Corporation tax (19%-25%) | Trust rates (45% on most income) |
| Best for | Long-term family wealth transfer with control retention | Targeted protection for vulnerable beneficiaries |
For most Harrow property portfolios above £1.5m, the FIC structure is the more tax-efficient long-term wrapper. Discretionary trusts work better for protective scenarios (vulnerable beneficiaries, divorce protection) or for shorter-term inter-generational transfers.
Gifting property: the 7-year rule and CGT
A gift of property to a non-spouse becomes a Potentially Exempt Transfer (PET):
- 1Gift made today: PET clock starts.
- 2Donor survives 7 years: gift falls outside the estate entirely. No IHT.
- 3Donor dies within 7 years: gift comes back into the estate at original gift value, with taper relief reducing IHT after year 3.
- 4Taper relief: 0% reduction at 0-3 years, then 20%/40%/60%/80% at years 3-4, 4-5, 5-6, 6-7.
The CGT trap: gifting a buy-to-let property to children is a deemed market-value disposal for CGT purposes. The donor pays CGT today on the gain even though no cash changes hands. For a £400,000 property with a £150,000 base cost, the donor faces £60,000 of immediate CGT.
Why BPR does not apply to rentals
Business Property Relief (BPR) at 100% exempts qualifying business assets from IHT. Many landlords assume their portfolio qualifies. It almost never does:
- Standard residential lettings are treated as investment activity, not trading, by HMRC.
- BPR specifically excludes activities consisting wholly or mainly of holding investments.
- Furnished Holiday Lettings are also denied BPR, even when they qualified for FHL income tax treatment.
- Property development companies (genuine trading) qualify for BPR.
- Mixed-activity businesses where less than 50% is investment may qualify for partial BPR.
The IHT and Wealth Extraction Series
We're publishing two detailed pieces per week from this series. Check back shortly.
Cross-option agreements for joint investors
For property partnerships and joint ventures, cross-option agreements protect the surviving partner against losing control to the deceased's heirs:
- 1Each partner takes out life insurance on the other.
- 2On a partner's death, the policy pays out to the survivor.
- 3A cross-option contract gives the surviving partner the option to buy the deceased's share at fair value.
- 4The deceased's estate retains the cash from the buyout, used to settle IHT and distribute to heirs.
- 5The surviving partner retains operational control without forced sale.
Dividend vs salary for SPV directors
For an active director-shareholder of a property SPV, the standard 2026 extraction stack is:
- 1Salary up to the secondary threshold (no employer NI) and personal allowance (no income tax).
- 2Pension contributions (employer route, deductible for the company, free of NI).
- 3Repayment of credit Director Loan Account balance (tax-free return of capital).
- 4Dividends from retained profits, taxed at 8.75%/33.75%/39.35% depending on the shareholder's marginal band.
Married couples can split shares 50/50 (or via different share classes) to use both partners' dividend allowances and basic-rate bands, materially reducing the effective extraction tax rate.
Restructuring at retirement
Many Harrow landlords reach retirement with portfolios accumulated over 20-30 years:
- Continue holding and drawing income: simplest, but full estate exposure to IHT on death.
- Gradual gifting to next generation: starts the 7-year clock, triggers immediate CGT.
- FIC structure: meaningful for portfolios above £1.5m where multi-generational planning matters.
- Partial sale and reinvestment in BPR-qualifying assets (AIM portfolios, EIS-qualifying companies): generates IHT-efficient assets at the expense of liquidity and risk profile.
- Equity release on main residence: liquidity without disturbing the rental portfolio, reduces estate by debt amount.
