UK Stamp Duty Rates: A 2010-2026 Timeline
How UK stamp duty has changed over the last 16 years: the December 2014 reform from slab to marginal bands, the introduction of the 3% additional-property surcharge in 2016, first-time buyer relief in 2017, the COVID holiday, the mini-Budget threshold rise, the surcharge increase to 5% in 2024, and the April 2025 threshold reversion.

Key reform moments
Pre-2014 slab system (historical context)
Before 4 December 2014, SDLT used a slab structure: one rate applied to the entire purchase price based on which band the price fell into. The thresholds at the time were £125k, £250k, £500k, £1m and £2m, with rates of 0%, 1%, 3%, 4%, 5% and 7%.
The slab system created sharp cliff edges: a £250,001 purchase paid 3% on the full amount (£7,500) while a £250,000 purchase paid 1% (£2,500). The £5,000 jump for £1 of price was structurally indefensible and was abolished in the 2014 reform. The modern marginal band system fixes the problem (any £1 of price increase adds at most that £1 multiplied by the band rate to SDLT).
Note: the same cliff-edge problem persists in two places in the modern system: the £500,000 FTB cliff (where £1 of price costs £5,000 in lost relief) and Scotland's ADS at 8% flat-on-full-price for second homes. The 2014 reform did not fix these because they apply only to specific buyer types and are seen as policy levers rather than structural anomalies.
