There is no excuse for any country not to do this TBH. The math is really easy and uses already available information: take the year's total federal spending for different things, specifically in the form of percentages of the year's total tax revenue (hopefully the government has been keeping track of what they've been using the money for) and multiply by the total taxes paid by a specific person and you get exactly how much of their money went to what. This assumes every person's tax revenue is treated the same which I'm pretty sure is at least mostly the case in every country.

If they release the national spending percentages (which they should) then it'd be pretty easy for individuals to calculate these themselves.
