Field help:
Have you received child benefit or allowances for a person of full age?
Enter here whether you have received child benefit or child allowances for an adult person.
If you share a household with a person of full age for whom you are not entitled to child benefit or child allowances, the tax relief for single parents cannot usually be granted.
A shared household (i.e. joint economic activity in a shared flat) is always presumed if another person is registered with your main or secondary residence. However, if you do not live in a consensual union, this presumption can be refuted.
