FFFFSSSS I have now replied to this 3 times the forum keeps eating my reply!

OK even shorter this time...

Child Bennefits rules changed in 2013.

If they earn over £60k profit from their business they don't get child benefits.

Based on not getting other credits, it is safe to assume their business does earn more than £60k profit.

TL;DR - They don't get child benefits no matter how many kids they have (this is how the equation works. Starts to reduce at £50k, nothing at all over £60k)

If you have an income of between £50,000 and £60,000 a year, the amount of extra tax you'll have to pay will be 1 per cent of the amount of Child Benefit you get for every £100 of your income above £50,000.

Now POST! Goddamn you forum...
