And even families with a combined income of up to £300,000 will be able to get the payments.
Plans due for consultation
However, about 1.2 million households where one parent – mostly mothers – stays at home will not be eligible for the help.
The scheme will be introduced for children under five by 2015 and extended to cover all those under 12 by 2020, under current plans.
Lower-income families where both parents work will get extra payments that will cover up to 85 per cent of their childcare costs, compared with the current 70 per cent.
The treasury will invite comments on the plans on Monday.
Sharon Hodgson MP, Labour’s shadow minister for children and families said: “Only David Cameron’s government could be so out of touch that they expect families to be grateful for help with childcare in 2015 when they’ve already seen costs spiralling and support taken away.
“This government has hit hardworking parents. Families with two children have already lost up to £1,500 in childcare tax credit.
“This government promised to be the most family friendly ever but hardworking parents have lost out while millionaires get a tax cut.”
