Hi I have 2 kids 9 and 6. Been claiming child benefit since they were babies. For the last few years my husband had a company car with fuel card adding £17k to his taxable income. This has pushed his modest income into "high income" I think and now I'm scared we owe thousands back that I just don't have. He pays all his tax through PAYE so it's never occurred to us we need to pay more. His personal tax free amount is actually negative so he pays tax on every penny he earns and more so actually his take home is very little compared to his "pre tax income"
Does anyone here know how to find out how much we owe and can we pay in installments? I can't believe no one ever told us about this and found out by chance
