Jointly owned property
Record who owns what, so the tax figures are yours and not the property's.
On a property's Finance tab, click the Personally control to open how the property is owned.
If more than one person owns it, this is where you set each share, so the tax is worked out on your portion.
It opens showing you as the sole owner; choose Shared with others to add a co-owner.
Setting the shares
Add each owner and the percentage they hold — You, then + Add a co-owner for a partner or family member, with their relationship. The shares must add up to 100%.
The panel above shows a property split 60/40 with a spouse: each owner, their share, and the total balanced at 100%.
The spouse rule (Form 17)
If you hold a property jointly with a spouse or civil partner, HMRC treats the income as 50/50 by default, whatever the deeds say.
That changes only if you have filed a Form 17 election. If one is in place, set the real split here; otherwise leave it at 50/50.
What it changes, and what it doesn't
Your books stay whole: rent, costs and cashflow keep showing everything the property earned. Only your tax figures use your share.
You are responsible for entering the beneficial share you actually own.
If the split looks wrong
- Total not 100%? The shares must add up — adjust one until the total balances.
- Tax unchanged after editing? Save the panel; the estimate updates once the new shares are stored.
