Delivering his Autumn Statement, Hammond said the scheme – first announced as far back as 2013 – would be introduced gradually from early 2017. The roll-out will begin on completion of pilot schemes which have been in place across parts of the UK since September.
Under the new Tax-Free Childcare scheme, eligible families will get 20% of their annual childcare costs paid for by the Government. The way it works is that for every 80p you pay into a newly created 'childcare account', the Government will contribute 20p.
This could mean up to £2,000 per child (the scheme assumes a maximum of £10,000-a-year childcare costs per child – if you pay more, you won't get more help).

There had been fears that childcare vouchers – a tax-efficient way to pay for childcare inside a salary sacrifice scheme set to run alongside the new scheme until 2018 – would be axed. But these proved to be unfounded as they were spared the chop.
