Clubman,
Wow.....you NEVER did the returns for the past 20 years!?! Had thought it was obligatory to fill those darned forms - on this point I'd agree with you - they're detailed, seem to be more so, each year.
Had become and am still paranoid about keeping up the tax affairs to date, after being ticked off by the Revenue for not declaring the bank interest 27 years ago - was wet behind the ears in those days....
