Re: A lot of commies in here
Better yet, have a system that automatically collects the tax from your pay as you earn it, handled by your employer utilising a standardised tax code for your personal situation... Let's call it something like PAYE or Pay As You Earn...
Those of a more complex nature can employ software or accountants to manage their tax affairs and the rest of us can just get on with earning a living.
Or is not letting take a crack at getting it wrong and having others skim off the top a better way somehow?
