Claiming legitimate expenses still means you're effectively avoiding tax but legitimately just like these people are legitimately avoiding tax.
Morals as got nothing to do with it.
Oh dear , have a word with yourself ......tax is only payable on profit .....PROFIT , not turnover.
By lowering your profit through claiming expenses you're still avoiding tax legit or otherwise....have a word with yourself.
You cant avoid paying tax that you never owed in the first place.
Dont be daft , you have not earned any money until you make a profit.
or , if you dont make a profit , you cant take any money out , to spend , on your living expenses etc .
I find it difficult to believe anyone with the get up and go to be self employed is that stupid ......so i can only assume your trolling.
