Am confuddled. Just checked by bank account online and saw 2 large payments for WTC and CTC were paid into my account yesterday. At first glance, it looks like a whole year's worth of money! 
We USED to claim, but our CTC stopped last year when DS left school, and we then continued to get a small monthly WTC payment until April this year. When our renewal forms came through this summer I didn't even bother filling them in because I started working part-time in May, and we are now over the threshold for any entitlement.
I received a letter last week saying we'd actually been overpaid one month's WTC for the tax year 2014-2015.
So why on earth have I been paid all this money when we haven't even submitted a claim this year?
Can I keep it please?
