Hi, I just had a letter from HMRC saying I owe them over £600 for nanny's tax and NI!!!! I am pretty sure I paid it every month (through their Billpayment website), and have their email confirmations of all the payments- but when I went back to look at my online HMRC account two payments were missing completely and a third was listed as "incomplete". I have asked my bank for statements going back the last 18 months - PITA - as I don't have all my bank statements, but until I get that I can't be 100% sure that the money went through every time (although I'm pretty sure I would have noticed an extra £200 a month!). Anyone else had similar - just to give me a glimmer of hope through the weekend!
