You are thinking too "micro-level" ! Take a step back and think of the bigger picture.
Imagine a scenario with no taxes (I wish!) - ie ignore VAT, IT, CT etc. Suppose you spend 2,000 on equipment in order to provide a service costing
10,000. You make 8,000 and keep the lot - great!Now suppose we "overlay" a tax system on top of this. Tax is simply an "add-on" which is used to generate revenue for the state - the rules may be formulated in certain ways to try to "encourage" people to act in certain ways, but essentially that's just it - a tax just passes some money to the state.
So where will the money come from? Well, some can come out of the 8,000 which you make, and some can be paid (extra) from the purchaser of your service. It seems quite fair to take a *proportion* of your 8,000, and also seems quite fair to charge the purchaser extra - as a proportion of the amount that they are paying for the service. Suppose the state decides on the proportions 20% of 'profit' and 20% of 'price' (ie all tax rates are set to 20% - remember this for later!).
You should be getting 6,400 for your service, and the client should be paying 12,000. In this case, you have paid 2,400 (including the 20% sales/purchase tax) for the equipment & charged 12,000 for the service - so for you to net the
6,400, you need to pass over 3,200 in total to the authorities. It doesn't really matter to you how much of this is "income" tax and how much is the "sales/purchase" tax - but we say that the "income tax" part is 1,600 (20% of 8,000) and the "sales/purchase" part is also 1,600 [which is 2,000 output tax received (on service), less 400 input tax paid (on equipment)].If you could not reclaim the input tax, then you would net only 6,080 for your service (allowing for income tax relief instead, on the 400 input tax incurred - 400 x 20% = 80). This is an effective tax rate to you of 24% on your (true, real, pre-*all tax*) profit of 8,000. Higher than *either* of the "income" or "sales/purchase" taxes!! Seems a little unfair?
At a rather more extreme, suppose you needed to spend 40,000 for equipment in order to provide a service for 48,000 - this gives a reasonable 8,000 profit to you. Now, overlaying a tax system where "income" tax is 25% and "sales/purchase" tax is 20% would mean that (if you could not reclaim the sales/purchase tax on the equipment) that your effective tax rate on profit is ... 100%! [Equipment 48,000 with tax, service 57,600 with tax, of which you pay
9,600 over to authorities for "vat" and suddenly have no profit at all!]Of course, tax systems are going to reduce the net amount of money which you have to spend on things (income tax) and/or increase the amount which you need to spend on things when you buy them (sales/purchase tax) - but the fairest systems would seem to be to keep things in *proportions*. Then, if you would have had a certain amount of profit *without* any tax, you'll still have some profit *with* a tax system overlaid.
Surely it seems fairest just to take a *part* in tax - doesn't it?
