You could get Child Tax Credit for each child you're responsible for if they're:
- under 16
- under 20 and in eligible education or training
You don't need to be working to claim Child Tax Credit.
You can't claim tax credits and Universal Credit at the same time.
How much you'll get will depend on your circumstances. Child Tax Credit won't affect your Child Benefit.
Only one household can get Child Tax Credit for a child.
From 6 April 2017, most people will only get the child element of Child Tax Credit for up to 2 children. You'll still be able to claim it for more than 2 children if they were born before 6 April 2017.
