One CRUCIAL factor is not included in this $100 comparison by state -- personal income tax. BLS and the Tax Foundation have no way to calculate that in the formula, because the tax differs dramatically depending on what level of income you have.

For instance, while 7 states have zero income tax, uber-progressive (well progressive EXCEPT about Uber) California has a personal income tax that's, well, uber progressive -- varying from NEGATIVE (cash credits) to 13.3% -- by FAR the highest in the nation -- impossible to calculate in the formula.

Also ignored as impossible to calculate are fees, fines, and other state and local "non-purchase" levies by government. Fee-crazy California again "excels" in this area.

Hence the hypothetical $100 is AFTER-tax dollars. Other taxes included in a purchase (sales, excise, etc) ARE included in the comparison, but income tax is not. The REAL total difference between the states is often significantly higher as a result, but not included in this study.
