SCA Tax has launched Post Complete, a stamp duty calculation and review service designed to ease the compliance burden on conveyancers.
The service has been launched ahead of the HMRC proposed tax adviser registration changes, which are due in May 2026, which means filing SDLT returns is treated as tax advice for the purposes of the proposed tax adviser registration regime set out in the Finance Bill 2025-26.
Matthew Gannon, an AAT-qualified tax specialist and SDLT expert who joined SCA Tax from PwC last year to lead the Post Complete team, said: “We know these changes are coming, and there’s no benefit in waiting for the final guidance before firms start putting stronger processes in place.
“SDLT already creates pressure points in transactions – the last thing the market needs is completions being delayed because teams are forced to rebuild their approach overnight.
“Post Complete is designed to help property professionals stay ahead of the change, keep transactions moving, and make sure SDLT positions are properly assessed and documented.
“We launched earlier this month, and we’re already speaking to conveyancing firms and the wider property chain – including estate agents, auction houses, mortgage brokers and financial advisers – because this affects everyone involved in getting deals over the line.
“If we want the market to move, we need processes that reduce delays, not add to them.”
Every transaction is reviewed by tax-qualified specialists, and firms receive, audit-ready documentation for client files, including a professional PDF Tax Calculation Certificate and supporting assessment breakdown.
Each calculation is also backed by specialist professional indemnity insurance underwritten by Allianz.
Pricing starts from £50 for personal purchases and £100 for business purchases, with monthly invoicing available.
