i filled my first tax return in in may, i 'worked out' at the time id earned a particular figure..when i filled in tax return i mistakenly added this to my previous benefits id received...this made it over the tax threshold so billed me a few hundred pounds...i realised what id done and contacted them, sent letter off last week saying figure should actually have been x not y..meaning i wouldnt pay tax....Now as im sat working out my estimated earnings for this year, im looking back and (dont ask me how i am so stupid)..the figure i actually 'earned' as in money i was paid is twice as much as i 'realsied' and sent letter about.
So my question is...the 'total income' box, should that be what ive received in wages or the money i have left when ive paid bills bought equiptment etc?
if its the money i have actually been paid then ive f*cked up big time!
