If you have been on maternity leave this year and claim tax credits, you can disregard £100 per week that you are on paid mat leave from your income when you declare it to tax credits. Over the 39 weeks that is £3900, so worth knowing about!
Apparently it is written on the annual review form but I never saw it so missed out on the chance to disregard £3100 from 08-09. Knocked £800 off this year though which has been nice for the last few weeks
Spread the word! I'm going to repost this on other topics because if you try to go back to a year before this one they won't recalculate it.
