Use form 17 if you own property with your spouse or civil partner and want to change the split of income to an actual basis for tax purposes.
Ref: Form 17 https://public-online.hmrc.gov.uk/lc/content/xfaforms/profiles/forms.html?contentRoot=repository:///Applications/SpecPersTax_iForms/1.0/17&template=17.xdp
If you live with a spouse or civil partner and have income from property you jointly own, you’ll normally be taxed on an even split of the income between you.
Use this form if you want to change the split of income to your actual share of ownership.
You’ll also need to provide evidence that your beneficial interests in the property are unequal, for example a declaration or deed.
