MoneySavingExpert founder Martin Lewis has warned how 800,000 families are missing out on tax-free childcare worth up to £2,000 a year.
You can get up to £500 tax free every three months (up to £2,000 a year) for each of your children to help with the costs of childcare.
This goes up to £1,000 every 3 months (up to £4,000 a year) if a child is disabled.
