HMRC letter is 'misleading'
In a nutshell, the letter from HMRC says that the income thresholds have come down to around £26,000 for a family with one child, £32,200 for a family with 2 children. What is not made totally clear in the letter is that there are exceptions for families with more than 2 children, paying for childcare and if there is disability involved. In these cases it could mean that, if your income is as high as £50,000 or £60,000, you may still qualify
In short,if you're not sure if you qualify or not, make your claim anyway. The HMRC Tax Credits Calculator will be updated from April 6th.
