Tax credits: How many hours do you have to work to get Working Tax Credit? | Personal Finance | Finance
If you are in a couple with at least one child, between you you both need to work at least 24 hours.
One of you in the couple must work at least 16 hours a week to be eligible for the benefit.
If your working hours change regularly, Citizens Advice explain: “If your working hours are unreliable and irregular, you might not be able to say what hours are normal for you.
“If this is your situation, contact HMRC to get advice on how to describe your weekly hours. Or you can contact your nearest Citizens Advice.”
If you usually work more than the hours you are contracted for, you need to give HMRC details of the number of hours you actually work.
Further information on what counts as work and income can be found on the Government website.
