The childcare voucher scheme is closed to new applicants. However, it is still available to people who joined the scheme on or before 4 October 2018.
It allows you to take up to £55 a week of your wages for childcare, which you do not pay tax or National Insurance on.
You cannot continue to claim childcare vouchers if you successfully apply for Tax-Free Childcare.
