If you haven’t owned a property before, then it’s possible that you won’t need to pay Stamp Duty on your first Shared Ownership home. This is due to the minimum threshold at which Stamp Duty is charged on a purchased home. With the changes to Stamp Duty as of 1st April 2025, however, this may differ depending on your specific circumstances. 

Shared Ownership buyers have two options when paying Stamp Duty: 

• You can choose to pay stamp duty on the full value of your home, and effectively get this financial lump sum out of the way early. This option also means you won’t need to pay stamp duty after, even if you staircase to a larger share down the line.
• You can pay stamp duty on the share you’ve purchased, instead. If you’re buying a 10% share in a £250,000 home, this may mean you won’t pay any stamp duty as part of your initial purchase.

There are benefits to choosing either option, and a tax advisor will be able to guide you towards the most suitable approach for your situation.
