[quote name='beerdragon' post='20693' date='Jun 20 2007, 12:12 PM']One thing i have never bothered to enquire about is the tax situation, are you supposed to declare anything you earn by gigging? or is there a threshold.[/quote]
If being a musician is in addition to a main income then you need to complete a yearly tax return with relevant self assessment sheets detailing additional income. Any profit can be offset by expenses such as buying equipment, petrol cost to gigs. You should pay tax on the net income (if any).
