Understanding Multiple Dwellings Relief
What Was MDR?
Multiple Dwellings Relief was a stamp duty relief available when purchasing more than one dwelling in a single transaction. It calculated tax based on average price per dwelling.
How It Was Calculated
MDR calculated SDLT using the average price per dwelling, then multiplied by the number of dwellings. The minimum rate was 1%, even if average price was below threshold.
Abolition
MDR was abolished on 1 June 2024 following the Spring Budget 2024. Transitional rules applied for contracts exchanged before 6 March 2024 until end of 2024.
MDR vs Standard SDLT Examples
| Scenario | Standard SDLT | MDR SDLT | Saving |
|---|---|---|---|
| 3 flats at £150k each (£450k total) | £12,500 | £4,500 | £8,000 |
| 6 houses at £200k each (£1.2m total) | £54,000 | £45,000 | £9,000 |
| 2 properties at £100k each (£200k total) | £1,500 | £2,000 | -£500 |
Note: These are historical calculations. MDR is no longer available for new purchases.
Special Considerations
Transitional Provisions
Contracts exchanged before 6 March 2024 but completing after 1 June 2024 could still claim MDR until 31 December 2024 under transitional rules.
Retrospective Claims
You can claim MDR retrospectively for purchases completed before abolition where the relief was not initially claimed. Claims must be made within 12 months of completion.
Alternative: 6+ Dwellings Non-Residential Rates
Purchases of 6 or more dwellings may qualify for non-residential SDLT rates (0-5%) if treated as a commercial property investment, offering significant savings.
Refund Claims for Historic Purchases
If you completed a multiple dwelling purchase before abolition and paid more SDLT than required, you may be able to claim a refund if within the amendment window.
MDR Abolished
Multiple Dwellings Relief was abolished on 1 June 2024. This calculator is for historical reference and transitional claims only. New purchases completed after this date cannot claim MDR. For purchases of 6 or more dwellings, consider whether non-residential SDLT rates may apply instead.
