Pick an estate value to see exactly how much Inheritance Tax was due in the 2023/24tax year, using that year's Nil-Rate Band (£325,000), Residence Nil-Rate Band (£175,000) and 40% headline rate. Figures cover both single-person and married-couple scenarios (transferable NRB + RNRB).
What was different about 2023/24
The 2023/24 Inheritance Tax year saw the Nil-Rate Band (£325,000) and Residence Nil-Rate Band (£175,000) both frozen — a freeze first applied from 2021 and now extended further. The £2,000,000 RNRB taper threshold also stayed put, meaning fiscal drag pulled more estates into IHT as house prices and asset values grew.
