so i have had my renewal pack through for family tax credits today but am really worried about ringing them up as the actually amount on my partners p60 is less than the amount i estimated for 2011 to 2012 due to him being made redundant last july until september,so the actually figure is about 2000 less than what i had estimated so will this mean we have been overpaid and we owe them money or will it mean we have been underpaid and they will owe us??does anyone know??,i have been claiming family tax credits for years but always been quite spot on with our estimates so haven't got a cluehelp!!!!
