Ive made a mistake! I have 2 children. 2 year old and 6 months. We have been getting child benefits since the first was born. I didn’t realise there was an income cap and my husband is over it so we shouldn’t be receiving the benefit. We are now having to fill out a self assessment and repay the money. Does anyone have any idea what the repayments would be? Do you just pay back the amount you’ve received? Can you pay it back monthly or is it one payment? Is there a fine? I’m freaking out as it was totally my mistake and I’m worried we’re going to be due the tax man thousands.
