Can an accountancy practice file SDLT returns?

Yes, provided the practice is enrolled for HMRC Stamp Taxes Online as an agent and holds a STORN. You don't need to be a conveyancer.

Does it handle company purchases of residential property?

Yes. It applies the higher rates for additional dwellings and, above £500,000, the 17% flat rate (15% before 31 October 2024), unless the company qualifies for relief such as a property rental business.

How are non-resident clients handled?

Tick the non-resident question and the 2% surcharge is added to every band for residential purchases from 1 April 2021. The return's residency declaration is completed automatically.

Can I show my client how the tax was worked out?

Yes. Every case has a printable band-by-band calculation summary carrying your firm's name.

What about higher-rates refunds?

If the higher rates were paid because the client's previous main residence had not sold, the case is flagged with its 36-month refund window so you can make the claim when it sells.

Is there a minimum commitment?

No. The pay-as-you-go plan has no monthly fee — you pay only for accepted returns.
