Tax-deductible Expenses?

[Kayjay<P> <P><P>"Passer sa vie à lutter contre la connerie est le meilleur procédé pour mourir dépuisement."<P>]

Does anyone know if the system for self-employed people in France is broadly along the lines of the UK as regards allowable expenses, ie one can deduct travel expenses (travelling to work in the UK, for example), share of heating/lighting, cost of computer etc and then pay tax on the remainder of one's income?

(Said without much hope that there will be any recognizable similarities!)

Is this posting helpful?

Also, when I was poking about on www.impots.gouv.fr yesterday and attempting to calculate impots on the calculating tool, I think it said you can either take a standard 10% for expenses or if they exceed  10% you can list your 'real' expenses that you can prove (receipts etc).

There must be a list of allowable expenses somewhere on the impots site if you look hard enough.

Must add, that I have zero expertize on the subject!
