Inheritance Tax Planning for Property Owners
IHT mitigation strategies specifically for individuals and couples with significant property portfolios or high-value main residences.
Quick Answer
Property owners face unique IHT challenges: high-value London homes exceed the nil-rate bands, buy-to-let portfolios create large taxable estates, and property is illiquid (hard to sell quickly to pay the IHT bill). Key strategies include: structuring property ownership between spouses, using life insurance in trust for liquidity, gifting rental properties (7-year rule), incorporating portfolios, using Business Property Relief where applicable, and trust structures for family homes.
The IHT Challenge for Property Owners
Property-rich estates are particularly vulnerable to IHT. A London family home worth £1.5M, plus a £300,000 buy-to-let and £200,000 in savings creates a £2M estate. After the nil-rate bands (£1M for a married couple with residence nil-rate band), the remaining £1M is taxed at 40% = £400,000 IHT.
The problem is compounded by the illiquidity of property. IHT must be paid within 6 months of death, but properties can take months to sell. Without liquid funds (life insurance in trust), the family may be forced to take out expensive bridging loans or sell assets at a discount.
Key IHT Strategies for Property Owners
Effective planning strategies include:
- Restructure ownership: split properties between spouses to use both nil-rate bands and residence nil-rate bands
- Life insurance in trust: provide liquid funds to pay the IHT bill without increasing the estate
- Lifetime gifting of rental properties: start the 7-year clock early on buy-to-let portfolios
- Incorporation: transfer a buy-to-let portfolio to a limited company (corporation tax at 19-25% vs IHT at 40%, plus potential BPR over time)
- Family Investment Companies: pass property value to the next generation while retaining control
- Equity release (lifetime mortgage): gift money to children now, reducing the estate, while the loan reduces the estate value on death
- Downsizing: sell the large family home and gift surplus to children (7-year rule)
The Residence Nil-Rate Band Trap
The residence nil-rate band (RNRB) of £175,000 sounds generous, but it tapers away for estates above £2M. For every £2 above £2M, the RNRB reduces by £1. By £2.35M (individual) or £2.7M (couple), it's gone entirely.
Many London property owners have estates above £2M without realising it — a £2M home and £500K in investments is enough to start losing the RNRB. This means effective IHT planning for high-value estates must look beyond the RNRB and focus on gifting, BPR, and trust strategies.
Relevant Legislation
IHTA 1984 — full IHT framework. RNRB: FA 2015 Sch.4. RNRB taper: FA 2015 Sch.4 Para.8. BPR: IHTA 1984 s.103-113. Incorporation: TCGA 1992 s.162 (incorporation relief).
Practical Example
A married couple in London with a £1.8M home and £700K in buy-to-let properties faced IHT of approximately £600,000. We implemented: (1) restructured property ownership to maximise both nil-rate bands and RNRB, (2) placed £500K life insurance in trust for liquidity, (3) started a gifting programme for the buy-to-let portfolio (7-year rule), (4) set up a discretionary trust for £325K of investments. Projected IHT reduced to under £200,000 — a saving of £400,000+.
Common Mistake
Assuming the family home will qualify for full RNRB. If the estate exceeds £2M, the RNRB tapers away — and many property-rich estates lose it entirely. Another critical mistake is not having life insurance in trust — without it, the insurance payout adds to the estate and is itself subject to 40% IHT, defeating the purpose.
