Log in to the HM Revenue and Customs (HMRC) Stamp Taxes Online service to file your Stamp Duty Land Tax (SDLT) return as a solicitor, agent or legal conveyancer.

Before you start

You need to register for Stamp Taxes Online before you can file your SDLT returns online.

You can’t use the online service if you’re an individual buying property and you aren’t represented by a solicitor, agent or legal conveyancer. Complete a paper return instead.
