As the title says I haven't done my tax in a long time, been working full-time for the last 7 years and have 7 years worth of tax ready to be processed on the my gov app but have a few years previous to that where I was either working cash in hand or only intermittently working.
How screwed am I?
How much will this cost me at a tax agent?
How far back will I need to go to get everything up to date?
Cheers
