Joint property income of spouses or civil partners (UK)
Spouses or civil partners living together are generally taxed on an equal share of income from jointly held property, subject to statutory exceptions. Where they have unequal beneficial interests and the income entitlement follows those interests, a valid Form 17 declaration with supporting evidence can replace the default split with the actual proportions. They cannot freely choose an arbitrary tax split, and beneficial joint tenancy and other exclusions require separate consideration.
Worked example
A married couple living together hold qualifying rental property with evidenced beneficial interests of 70% and 30%, and income follows those proportions. If a valid Form 17 declaration and all other conditions apply, £10,000 property income is allocated £7,000 and £3,000; otherwise the default rule must be considered.
Common mistake
Assuming a couple may elect any convenient ratio irrespective of actual beneficial ownership, or assuming the default split applies to every jointly owned asset.
