Recent data reveals a significant increase in inheritance tax (IHT) refunds linked to property sales, attributed to declining house prices. The rise in successful claims, which jumped from 5,070 in 2024-25 to 10,550 in 2025-26, indicates a growing trend that could have substantial implications for landlords and property investors.

How Do Falling House Prices Affect IHT Refunds?

The increase in IHT refunds is directly correlated with a downturn in house prices, which has made it easier for estates to qualify for refunds. Properties must be sold within four years of the owner’s death to be eligible for these refunds, while other investments like shares must be liquidated within a year. This change in the housing market dynamics means that more estates are likely to benefit from tax relief.

Who Is Most Impacted by These Changes?

Landlords and property investors are particularly affected by these developments. As property values decline, the potential for IHT refunds becomes more relevant for estates that may not have previously considered selling. This situation could incentivize property owners to reassess their portfolios and consider selling before further depreciation occurs.

What This Means for Property Investors

For investors, the rise in IHT refunds may signal an opportunity to enter the market or adjust existing strategies. With the potential for tax relief on property sales, landlords might find it advantageous to sell under current conditions. Understanding the implications of IHT in relation to property value fluctuations is important for making informed decisions.
