How much does internet service really cost, once you add the income tax behind it?
Federal law bans state sales tax on internet access almost everywhere — a rare case where the exemption is the rule, not the exception.
The Internet Tax Freedom Act permanently bans state and local sales tax on internet access nationwide — with one narrow grandfather clause for 7 states that taxed it before the law existed: Hawaii, New Mexico, North Dakota, Ohio, South Dakota, Texas, and Wisconsin. Unlike most 'exempt in most states' categories on this site, this one has a precise, federally-mandated list rather than a fuzzy majority.
- No sales tax applies — the modeled default for the 43+ states covered by the federal exemption. The 7 grandfathered states (HI, NM, ND, OH, SD, TX, WI) may still tax internet access and would owe more than shown here.
The Internet Tax Freedom Act bars state and local sales tax on internet access nationwide, so $0 is correct almost everywhere. Seven states are grandfathered in and may still tax it; that exception is described below but is not applied to the figure.
The income tax in this figure is still computed from Texas and your filing status.

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.
