Budget 2015: Working parents discuss tax credits

The government says it needs to find a further £12bn in savings from the annual welfare bill to meet its goal of balancing the books by 2017-18.

With Prime Minister David Cameron promising an end to what he called the "ridiculous merry-go-round" of taxing low earners then handing money back in benefits, many are expecting the axe to fall most heavily on tax credits.

The working tax credit entitles parents who work a certain number of hours per week (16 for single parents, 24 for a couple with kids, for example) to receive just over £2,000, and extra money towards childcare.

However, by working for more hours than the minimum, recipients begin to lose this credit once their wages hit a set ceiling, and this can also lead to reductions in other benefits, like the child tax credit, which is means-tested.
