In 2013, then Chancellor George Osborne introduced new rules for families in receipt of Child Benefit.
He scrapped the benefit for anyone earning £60,000 a year or more and reduced the payout for anyone earning between £50,000 and £60,000.
However, to further complicate matters, he said that if two parents earned £49,000 each (a total of £98,000 between them), they could still claim it - yet if one parent earned £60,000 and the other nothing, they couldn't.
It meant families earning above this threshold would have to repay part - or all - of the money each year, in the form of a self-assessment.
This is typically at 1% for every £100 earned over £50,000, and 100% once you earn over £60,000.
And now is the time to take action if you've fallen into the 'high income child benefit charges' bracket for the current tax year.
If your household income is over £50,000, you have until Saturday, October 5, to notify HMRC to avoid having to complete a self-assessment form for 2018-2019.
This will ensure that you receive an adjusted tax code. Failing to do so will mean you have to file a tax return and pay any extra money back by 31 January.
