What is Jointly Held Property Election (Form 17)?

A declaration allowing married couples to split rental income in proportions other than 50/50, matching actual beneficial ownership.

Full Definition

By default, HMRC treats income from jointly owned property between spouses or civil partners as split 50/50, regardless of the actual ownership shares. If the property is owned in unequal shares -- for example 90/10 -- the couple can submit Form 17 to HMRC to have the income taxed in line with actual beneficial interests. The election must reflect a genuine difference in beneficial ownership (not just legal title), and supporting evidence such as a declaration of trust is typically required. The election takes effect from the date it is submitted and cannot be backdated. It is commonly used where one partner pays a lower rate of income tax to reduce the overall household tax burden on rental profits.
