The new rules on working tax credits from the start of the 2012/13 tax year will hit around 212,000 low income families, according to information published by the House of Commons Library. This will reduce their income on average by £2,600 each year.
Up till now, most couples with children have qualified for working tax credit, provided one partner works at least 16 hours each week. But from April 2012 couples will need to work 24 hours between them, with one partner working at least 16.
