We get child tax credit and my dad has very kindly gifted us a large sum of money to pay off a chunk of our mortgage as a kind of early inheritance. This money is sitting in my account while I wait for the mortgage renewal date and can pay it without incurring an early repayment fee. Will this have any impact on our tax credits? Whenever I have filled out the forms it has never asked regarding savings, and since we've only ever had a few grand each hadn't really thought about it. But as this is a large sum (albeit won't be sitting there for too long) I just feel rather nervous.
