Shared ownership: market value election and first-time buyer stamp duty
Shared ownership market value elections
A market value election can make SDLT depend on the full value of a shared ownership home. First-time buyer relief may then apply to that amount.
- The election is permanent.
- Rent is not counted for SDLT where the election applies.
- Later shares may not create further SDLT.

Shared ownership: market value election and first-time buyer stamp duty

Shared ownership: market value election and first-time buyer stamp duty
A market value election can mean HMRC works out stamp duty on your home’s full value, not just the share you first buy.
If you qualify as a first-time buyer, that may give a better result. It can also mean no further SDLT when you buy more shares.
What this rule is about
Shared ownership usually starts with buying a share and paying rent on the rest. You may then buy further shares over time.
A market value election lets you deal with SDLT up front on a value set out in the lease.
That choice is permanent. You therefore need to consider it before you file the return.
What the official source says
HMRC’s manual says first-time buyer rates apply to the amount used for the market value election. In its example, that amount is the full market value of the home, rather than the price of the first share.
- The lease must be a qualifying shared ownership lease.
- The election is made in the SDLT return, or an amendment.
- Once made, the election cannot be withdrawn.
- The stated market value becomes the amount used for SDLT.
- Rent under the lease is not counted for SDLT where the election applies.
What this means in practice
The election can bring forward the tax question. Rather than consider SDLT as you buy later shares, HMRC bases it on the stated value at the start.
For an eligible first-time buyer, the first-time buyer relief bands then apply to that value.
The key point is simple: the price of your first share may not decide the tax.
- Check the full market value written in the lease.
- Check whether all buyers are first-time buyers.
- Check whether the full value is within the relief limit.
- Keep proof that the election was included in the return.
How to analyse it
Start with the lease, not the estate agent’s price for the share. Then work through the tax position in this order.
- Is this a qualifying shared ownership lease?
- Does the lease state the value used to calculate the premium?
- Has a market value election been made?
- Does each buyer meet the first-time buyer rules?
- Are there linked purchases that could affect the relief?
- Has any SDLT due on the first grant been paid?
Example
Amir is a first-time buyer. He pays £225,000 for a 50% share in a home worth £450,000.
He makes a market value election, so HMRC works out SDLT using £450,000. HMRC’s example applies 0% to the first £300,000 and 5% to the remaining £150,000.
The bill is £7,500. No SDLT is due on the rent, and the example says no further SDLT is due if Amir later buys more shares or the whole home.
Why this can be difficult in practice
You might assume the election is always helpful because it prevents tax on later shares. It is not that simple.
It means HMRC considers SDLT on the full stated value at the beginning, even though you are buying only part of the home then.
- A first share price and full market value are different figures.
- First-time buyer relief is not automatic.
- One buyer’s earlier home ownership can prevent the relief.
- An election cannot later be cancelled because circumstances change.
Key takeaways
- A market value election uses the value stated in the lease.
- First-time buyer relief can apply to that value if its conditions are met.
- The election can remove SDLT on rent and later share purchases.
