We basically have that, except it's goods X, Y, Z are untaxed at rates a, b, c. That is, those goods are tax exempt, a.k.a. they're deductible expenses. Some of those goods get you a tax credit. Multiply this by tens of thousands. And you get them in various ways, a handful are on form 1040, a bunch more are on form 1040A but those are just categories the actual deductions are found in a booklet that lists the specific goods and what their category is for 1040a, and there's literally asstonnes that have their own private worksheets to compute the deduction or credit, some of which must be filed, most of which don't even get filed but you have to do them to correctly compute the deduction or credit. It's this complicated because a tiny lobby with a lot of influence manages to go their own private "line" item deduction, and almost no one knows about this. It's accountants and tax preparation software.
