No state leaves them alone all year. Eleven stop for a weekend.
No state exempts them outright — eleven just stop taxing them for a weekend.
Groceries get exemptions. Clothing gets exemptions in some states. School supplies get none, anywhere — they're taxed like any other item you take off a shelf. What you get instead is a tax-free weekend, in eleven states, usually in August. It's a real saving. It's also an odd one, because it only helps people who can do their shopping in that particular week.
Unlike groceries, clothing or prescriptions, school supplies have no standing exemption anywhere in the country. They are ordinary taxable goods, charged at the full rate in every state that levies one. What exists instead is the tax holiday: eleven states suspend the tax for a weekend or a week each summer, typically capping the exemption per item. It is a genuine saving with an unusual shape — available to whoever can shop in a particular week, and worth nothing to whoever cannot.

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.

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?
It comes out of take-home, and take-home is what survives tax. Each repeat has to be earned in full before tax, which is why a modest annual figure needs a much larger salary standing behind it.
Does this cost the same in every state?
It does not. This category's tax treatment is a state decision, so the total moves when the state does — from a full exemption in some to the standard rate in others.
What does this figure leave out?
Enough to be worth saying out loud. The limits are listed on this page, because a figure that hides its own edges is more misleading than one that admits them.
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.
