“There are two issues: (1) Tax supposed to be due back 1999/2000 and interest charges for late payment. I left the country in 2001. I did not know I had to de-register as a self-employed. I never received any reminder, any claim regarding these old taxes. I was not aware therefore something may be due. I came back to the UK in 2004. I lived supporting myself and did not generate any income. My status was EEA citizen self-sufficient. HMRC claimed these taxes and interests recently (2013). (2) I was self-sufficient until January 2014 when I started working again. I have paid all the taxes due, but HMRC used these payments to cover old taxes never claimed since 2001 and penalties for late tax returns that were not due given I was self-sufficient.”
