Help - 10 years no tax return
I've been self-employed for ten years, since being made redundant in 2002 - in the first 2 years I was earning cz. £8k, living off savings, barely earning enough to heat the house, and I didn't file a tax return because I couldn't have afforded to pay it; things got slightly better the next couple of years, but I then had the fear of the back-taxes (and still unable to pay) to stop me filing a return; last 5 years I've been earning about £20k. I now have savings and can (probably) pay what I owe... I really want to clear this - but how do I start, and how bad are the penalties likely to be?
Obviously I'm going to get a lot of flak from you guys, and I deserve it, but any advice - and figures - much appreciated.
