HMRC’s intensified scrutiny of property valuations is shaking up estate planning. With inheritance tax receipts for the 2025/26 financial year hitting £8.5 billion—a staggering £200 million increase from the previous year—officials are leaving no stone unturned.
Referrals to the Valuation Office Agency (VOA) jumped by 23.5% in just one year, soaring from 11,845 to 14,631 cases by September 30, 2025. This marks a significant shift in how property valuations are scrutinized, especially given that the main nil-rate band for inheritance tax has remained fixed at £325,000 since 2009.
But why this sudden surge? The answer lies in technology. HMRC is employing artificial intelligence and data matching techniques to identify discrepancies in reported property values. Laura Walkley, an expert in estate planning, notes, “There has been a noticeable shift towards questioning figures submitted in IHT returns, rather than accepting them at face value.” This change means executors must tread carefully—if they misreport property values, they could face hefty financial repercussions.
The stakes are high—once estates exceed that nil-rate band threshold, a 40% inheritance tax rate kicks in. Executors who fail to report accurately risk not just additional taxes but also interest payments that could come out of their own pockets.
As market uncertainty continues to affect property transactions, accurate valuations become even more crucial. The pressure is on—executors must ensure every detail is correct or risk HMRC’s watchful eye.
“HMRC is clearly focusing on property valuations as a significant potential source of revenue,” Walkley adds. This heightened vigilance comes on the heels of record IHT receipts, which have now marked five consecutive annual highs.
Still, as investigations ramp up, one question lingers: how far will this scrutiny go? Will it deter individuals from making legitimate claims or simply lead to more thorough reporting?
For now, the uncertainty remains palpable. No timeline has been shared regarding how long this increased scrutiny will persist or what further developments may arise. As executors navigate these new waters, they must be prepared for both challenges and changes ahead.
