There can be a choice about when to pay
A qualifying shared-ownership purchase can involve a market value election or payment in stages. These are different tax approaches, not just different ways of funding the same bill. The appropriate choice depends on the full market value, initial share, rent and possible later purchases.
The ordinary calculator does not choose between them. Entering the price of a 25% or 50% share into a standard freehold calculator can omit relevant parts of the transaction.
A market value election
With an election, SDLT is assessed by reference to the property’s total market value, subject to applicable relief. HMRC explains that no further SDLT is then payable on later increases in the share under that election.
For example, paying £150,000 for half of a property valued at £300,000 does not mean the election is tested only against £150,000. The full £300,000 is central to that option. Ask for a written comparison of the tax choices before making the election.
Paying in stages and later staircasing
Without a market value election, the initial share and rent may be relevant to the first SDLT assessment. Subsequent acquisitions, often called staircasing, have their own rules. HMRC’s guidance explains the significance of increasing ownership beyond 80% and how related transactions are handled.
A later share may also cost a different amount because the property value has changed. Keep the original return and details of every share acquisition so the later calculation has a complete history.
First-time buyer relief needs a specific check
First-time buyer relief may be available in qualifying shared-ownership cases, but its treatment should be checked against the actual scheme and payment route. Do not infer eligibility only from the mortgage deposit or the fact that this is your first shared-ownership purchase.
Give the conveyancer the full market value, share percentage, premium, rent, proposed election and each buyer’s ownership history. Request an explanation of both the tax due now and how later staircasing could affect it. This guide concerns SDLT in England and Northern Ireland; other UK jurisdictions have separate rules.
