Pensions Stamp Duty Error?

Stamp Duty Land Tax, covered

Since 2006, Cornerstone have specialised in providing Stamp Duty advice to a wide variety of clients, from private homeowners to commercial developers, as well as solicitors dealing with land transactions.

The introduction of the ‘3% Surcharge’ on second properties in 2016 and the confusion generated which persists to this day, starkly highlighted the scope for error in Stamp Duty payments. In light of this, we have moved to develop multiple service areas and tools to help avoid costly mistakes on current and future purchases, as well as assisting in correction of historically incorrect transactions.

Multiple Dwelling Relief Advise and Help

We sought help from Cornerstone Tax for an SDLT relief - Multiple Dwelling Relief. It is a matter several mortgage advisors and solicitors claimed they had little idea. However, Mr Mehmod Anvarmia from Cornerstone helped us with the matter. Right from the first conversation, he gave us enormous confidence about our case, kept us dutifully informed all through the process, and ensured we successfully claimed the relief sooner and better than we had expected. World-class service by Mehmod and Cornerstone. Thanks again!!

Great service from Mehmod at Cornerstone

Mehmod at Cornerstone was extremely helpful and patient and knowledgeable, going over things a number of times on the telephone, before providing expert advice in a written document, which has proved invaluable. We would definitely use Cornerstone again in the future, and Mehmod in particular, as he went above and beyond in providing us with tax advice.
