Garage Stamp Duty Calculator

When you buy a garage on its own — not as part of a house — HMRC treats it as non-residential property for Stamp Duty Land Tax purposes. This is significantly cheaper than buying a residential property of the same value.

Non-residential SDLT bands (England, 2026)

• 0% on the portion up to £150,000
• 2% on the portion from £150,001 to £250,000
• 5% on the portion above £250,000

Practically, this means most garage purchases (which typically range from £15,000 to £100,000) pay £0 SDLT. Even a £200,000 multi-unit block would only pay £1,000.

Common confusion: the £40,000 myth

You may have heard "no SDLT under £40,000." That number relates to the 3% additional dwelling surcharge for second homes — which applies to residential property only. Garages aren't residential, so this rule doesn't apply to garage purchases at all.

When SDLT does apply to garages

• Garage included with a house sale — treated as part of the residential transaction at residential SDLT rates
• Multi-unit garage block above £150,000 — pays SDLT on the portion above £150k at 2% (or 5% above £250k)
• Mixed-use property with a garage element — may qualify for non-residential rates depending on facts

Scotland and Wales

This calculator covers England only. Scotland uses Land and Buildings Transaction Tax (LBTT) and Wales uses Land Transaction Tax (LTT) — different bands and thresholds. Get specific advice if buying outside England.

This calculator provides general guidance only. SDLT rules are complex and depend on your specific circumstances. Always confirm with a SDLT-aware solicitor before completing a purchase.
