Register for Stamp Taxes Online
Agents, solicitors and organisations can use Stamp Taxes Online to send HM Revenue and Customs (HMRC) Stamp Duty Land Taxes (SDLT) returns.
SDLT no longer applies in Scotland. Instead you pay Land and Buildings Transaction Tax when you buy a property.
Allow 10 working days (21 if you’re abroad) to register. Once you’ve activated your Stamp Taxes Online service, use it to complete, edit and store SDLT transactions.
If you’re not represented by a solicitor, agent or legal conveyancer, you must send paper returns.
Before you register
Only 1 person in your organisation needs to register. You can add other people if they need to access, edit or carry out SDLT transactions. Each user must activate and use their own User ID and password .
There are different arrangements to register to file online if you’re a:
- local authority
- government department
- an organisation not registered with Companies House
- not registered either as a self-assessed partnership or trust
Write to HMRC’s Birmingham Stamp Office for a reference number. You’ll need this number when you register. HMRC will ask you for more details about the organisation, and you’ll need these details later when you register for the online service.
