DH has been paying CM via the CSA for several years. His, and my, income has fluctuated a lot in that time, and DH has always updated the CSA with his income changes and sent through the updated tax credit award notices as we've had them.
Because of the various changes in income, the final tax credit award notices for the last couple of years (13/14 and 14/15) have both arrived in the last few weeks; which include an (expected) overpayment, which we will be paying back directly to HMRC; we're not having it deducted from future payments.
Will the CSA re-calculate the amount of CM owed during those periods based on the revised Tax Credit award notices?
