Not quite medicine, not quite food — so they get taxed.
Sold beside the medicine, shelved with the food, taxed as neither.
Vitamins fall between two rules. They aren't prescription medicine, so the exemption that covers your prescriptions doesn't reach them. Most states won't call them food either, so the grocery rule doesn't apply. That leaves the ordinary rate, which is what most people pay. A handful of states do treat them as food. So the shelf a bottle sits on tells you nothing useful about the tax.
Dietary supplements occupy the awkward middle of sales tax law. They are not prescription medicine, so the near-universal drug exemption does not reach them, and most states decline to call them food, so the grocery exemption does not either. The result in the majority of states is the full standard rate. A minority disagree and apply their grocery treatment instead, which is exactly why the aisle a product sits in tells you nothing reliable about what it will cost at the checkout.

Prices and wages are held at today's levels, and the return above is inflation-adjusted to match — consistent by design. The invested-instead line assumes the cash is contributed at the end of each year and left alone; it is an alternative use of the same money, never an extra cost on top.
Your position in the tax system
29.65% on the next dollarEvery extra dollar you earn is taxed at your marginal rate, not your average one — which is why a purchase costs more to fund than a paycheck stub suggests.
Marginal rates are read in gross-income terms: below the standard deduction an extra dollar of pay adds nothing to taxable income, so the true rate there is 0%, not the lowest bracket's. Excludes pre-tax deductions (401(k), HSA), which would lower all three.
Same purchase, different state

Each tax layer is the extra tax this purchase causes — that layer's tax at your income subtracted from its tax at your income plus the gross-up — so bracket boundaries the purchase straddles are handled correctly rather than smoothed over with an average rate.
Is a raise actually a raise?
you keep 70%A raise arrives on top of everything you already earn, so it is taxed at your marginal rate — not the average rate on your whole salary.
Federal, FICA, state and any local income tax — no pre-tax deductions, benefit changes, or payroll withholding quirks, all of which move the real figure. Moving into a higher bracket never taxes the income below the threshold: only the dollars above it pay the higher rate.

Questions people ask
Why does a small regular cost need such a big salary behind it?
Because you pay it out of what is left, and what is left is the small end of your salary. Every dollar spent on this has already been through income tax and payroll tax, so a cost that repeats has to be earned again and again at the gross rate — not the net one.
Does this cost the same in every state?
The price might, the tax does not. States classify this category differently, and the figure changes with the one you select.
What does this figure leave out?
Some things, and they are written down on this page rather than left for you to discover. Tax rules for this category have edges the model does not follow — the note below says which ones, so you can tell whether your own case sits inside the figure or outside it.
Why does a recurring outlay require disproportionate gross income?
Consumption is funded from post-tax income, so required gross income is the outlay divided by one minus the marginal rate on the relevant income slice. For a recurring cost that grossed-up figure recurs at the same cadence, which is why annualised gross requirement exceeds the nominal annual outlay by the full marginal wedge.
How does state tax treatment vary for this purchase?
Sales tax treatment of this category is determined at state level, with local add-ons layered on top where they exist. Classification varies between full exemption, a reduced grocery-style rate and the standard rate, so aggregate burden is not comparable across states without specifying the jurisdiction.
What are the stated limits of this category's model?
Modeling limits for this category are stated explicitly on the page rather than inferred. They typically concern classification edge cases, per-item caps, or local levies outside the modeled base. Where a limit applies to a reader's specific purchase, the figure should be treated as a lower or upper bound as the note describes.
