A phone plan is one of the few things Montana taxes without having a general sales tax at all. The gross income required is about $10,650 on a $75,000 salary, 13 of 51 states, because Montana's income tax runs about 3.84% effective at this income, and the money has to be earned before it can be spent. Montana charges no general sales tax. This is one of the things it taxes regardless, through a separate levy.
Delaware costs about the same for a phone plan
Prices in Montana
Shopping in Montana costs 9.76% less than the national average. Services, the kind of spending this is, run 6.55% below average, higher than prices overall. Counting from the most expensive, Montana ranks 41 among the states. A hundred dollars of average American shopping costs $90.24 here.
The cost above uses one national price for a phone plan, so these local prices are not in it. See how prices break down in Montana.
BEA regional price parity, all items: about 9.76% below the national level, rank 41 by price level, most expensive first. Other-services parity: about 6.55% below. A national-average basket costing one hundred dollars costs $90 here.
The category figures above apply a single national default price and are not adjusted for this price level. A parity measures what a basket costs, not what a salary is worth after tax. Full Montana price-level breakdown.

The 14.25% state/local wireless layer is a NATIONAL AVERAGE, not your state's rate. Real rates range from under 2% to over 25% depending on the state and locality, which is a larger swing than anything else on this page. The federal USF surcharge genuinely is national.
The income tax in this figure is still computed from Montana and your filing status.

Assumptions
- We use the national average phone tax rate (about 27.6%), not your own state's. Real rates run from about 16.82% in Idaho up to about 38.32% in Illinois.
- The federal part of that rate is itself an average. The FCC resets its rate every three months, so the exact charge on your bill shifts from quarter to quarter.
- The invested-instead comparison assumes you keep paying the same monthly bill for however many years you choose, and that the money would have been invested at the long-run market return instead.
- Uses the national average combined wireless tax/fee rate (about 27.6%) rather than your specific state — actual combined rates range from about 16.82% (Idaho) to about 38.32% (Illinois).
- The federal Universal Service Fund component is itself a national average of an effective rate (a safe-harbor percentage of the bill × the FCC's quarterly contribution factor) — real carrier line-items vary quarter to quarter as the FCC resets that factor.
- The compounding comparison assumes the money is a fixed monthly commitment held for the years you specify, invested at the long-run market return if it weren't spent — the same lens as the coffee-habit category.

Your position in the tax system
35.3% 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 65%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.
The arithmetic, for Montana
Nothing below is illustrative — it's the real chain the calculator runs for a single filer earning $75,000 in Montana, 2026 tax year. Follow it step by step and check our work.
| Gross salary | $75,000 | Where every calculation starts. |
|---|---|---|
| Less the federal standard deduction | −$16,100 | The 2026 figure for a single filer. |
| Federally taxable income | $58,900 | What the bracket table is applied to. |
| Federal income tax | −$7,670 | Top bracket reached: 22.00%. |
| FICA — Social Security and Medicare | −$5,738 | 7.65% up to the wage base, then 1.45% above it. |
| Montana taxable income | $58,900 | After Montana's own deduction, which differs from the federal one. |
| Montana income tax | −$2,877 | Marginal rate on the next dollar earned here: 5.65%. |
| Take-home pay | $58,716 | $16,284 withheld — 21.71% of the salary never reaches you. |
That's the gap between a price tag and a real cost: it takes roughly 1.28 earned dollars to spend one here, and that's the multiplier this page applies to every purchase.
What's different about Montana
- On income tax Montana sits in the middle: about 3.84% at this salary, rank 22. No great advantage, no great penalty.
- Montana lands mid-table for a phone plan — rank 13, $10,650 of gross income. End to end the country covers $1,419, from Alaska at $9,794 to California at $11,213.
- On this one, Montana's nearest match is Delaware at $10,808, a gap of $159. Adding up the whole stack tends to put unlike states side by side.
- Montana taxes the pay stub and leaves the till alone. Few states are simply cheap or expensive — mostly they pick a different moment to collect.
- Montana's effective state income tax at the representative salary is about 3.84%, ranking 22 nationally — mid-distribution, with neither the structural advantage of a no-tax state nor the drag of a top-decile one.
- Montana sits mid-distribution for a phone plan at rank 13, requiring $10,650 of gross income. The national spread is $1,419, from Alaska at $9,794 to California at $11,213.
- Montana's closest analog for this purchase is Delaware at $10,808, $159 apart. Composing every layer tends to compress apparent differences that a single-layer comparison would exaggerate.
- Collection in Montana sits on the earn side, with an income tax and no general sales tax. Two states with similar total burdens can therefore produce materially different results on any given purchase, depending on which layer that purchase touches.
What this page can't tell you
Worth being straight about, because a number without its limits is just a claim.
- These figures assume one filer with no dependants. They also assume nothing goes into a retirement account or an HSA before tax, and no itemized deductions. Any of those would cut the tax. That would cut the true cost too.
- Ownership costs fall back on national averages sometimes. That happens where a state figure does not exist, or could not be checked against a primary source. The data panel on the result says so outright when it does. We do not dress an estimate up as a measurement.
- Figures assume a single filer with no dependants, no pre-tax retirement or HSA contributions, and the standard deduction rather than itemized deductions. Each of those would reduce taxable income and therefore the gross-up, so the figures here should be read as an upper bound on the earn-side requirement for this household shape.
- Ownership-layer inputs fall back to national averages where a state-level figure is unavailable or could not be verified against a primary source. Those fallbacks are disclosed per-figure in the provenance panel rather than being silently blended into the total, so an estimate is never presented with the same confidence as a measurement.
Questions people ask
Is Montana an expensive place for this, or not?
This is an ordinary result. The earning figure of $10,650 is close enough to the middle that the state barely enters into it — the price and your own tax bracket matter more.
Is there really no sales tax on this in Montana?
Correct for the state's general sales tax. Local levies and product-specific excise can still appear, and the tax taken out of your pay before you shop is untouched by any of it.
Where in the country is this cheapest?
Alaska is the lightest, and doing this there would save you $855 of earning against Montana. At the other end, California would cost you $564 more.
This is a monthly cost — does the state matter more or less?
More, and it compounds quietly. A one-off gap you absorb once. A monthly one repeats for as long as you live there, which is how a difference too small to notice becomes a number worth moving for.
What is this figure leaving out?
There is a declared gap. Rather than fold in a guess, the page names what is missing and leaves it out of the arithmetic, which keeps the number defensible even though it is incomplete.
Where does Montana sit relative to the national median here?
Montana is within a couple of percent of the national median, at $10,650 — a gap of $186. The state variable is therefore not the dominant term for this purchase; marginal rate on the buyer's own income slice is.
How does the absence of a general sales tax affect this purchase?
Montana levies no general sales tax, so the purchase-side component of the gross-up is limited to any product-specific excise and any local levy the model records. The income-side wedge is unaffected; required gross income remains $10,650.
What is the national spread on this purchase?
Against Alaska at the light end, Montana carries $855 of additional gross requirement; against California at the heavy end it is $564 lighter. ⚠️ The model holds the pre-tax outlay constant across states, so the spread reflects tax structure alone and not regional price levels.
How does recurrence interact with the state differential?
The state differential is multiplicative in the number of occurrences. For a monthly outlay the annualised gap equals the per-occurrence gap times the periods per year, which is why recurring categories separate states far more sharply than one-off purchases of the same nominal value.
What falls outside the model for this category?
The category declaration records at least one component outside the model's scope. It is excluded from the computation rather than estimated, in line with the project's rule against unsourced figures; the reported requirement of $10,650 is therefore a lower bound on total cost.
