Key takeaways
In Montana, a 5% raise on $100,000 is about +0.8% real after tax and 3.5% CPI-U (rank #34).
After-tax raise is +4.4%; tax drag is about 0.7% before inflation.
Take-home moves from $74,391 to $77,626 (+$3,235) on the single-filer model.
A 3% COLA is a real pay cut in Montana: after-tax +2.6% → real -0.9% vs 3.5% CPI-U.
Break-even nominal raise at $100k in Montana is about 4.1% (smallest modeled raise with real growth > 0).
A 10% raise yields about +5.0% real in Montana after the same tax + CPI layers.
Employee FICA is 6.2% / 1.45% nationwide (IRS Topic 751); BLS ECI private wages rose 3.1% YoY (constant-dollar -0.4%).
Federal brackets and FICA are the same everywhere. Montana’s state income tax adds a larger wedge on raise dollars than no-wage-tax peers. Then 3.5% CPI-U turns that after-tax raise into the real raise.

We convert a 5% nominal raise into (1) after-tax take-home growth and (2) inflation-adjusted real growth using BLS CPI-U.
Federal brackets and FICA are the same in every state. State income tax is what changes the after-tax raise percentage.
Example: on $100,000, a 5% raise grows take-home by about +4.4% in Texas vs +4.1% in California — before CPI.
Extra dollars of salary are taxed at your marginal federal rate, plus employee FICA: Social Security 6.2% (wage base $184,500 in 2026) and Medicare 1.45% (IRS Topic 751).
Progressive high-tax states often show a larger tax drag on the raise dollars than no-wage-tax states.
In California, tax drag on the 5% / $100k vignette is about 0.9% — leaving an after-tax raise near +4.1%.
We use BLS CPI-U +3.5% (12 months ending June 2026). Real raise % = ((1 + after-tax raise %) ÷ (1 + inflation %)) − 1.
Core inflation (BLS CPI-U less food & energy +2.6% (12 months ending June 2026)) is lower than headline all-items; we use headline CPI-U so the vignette matches the figure most raise-season articles cite.
With after-tax raise ~+4.1% and CPI 3.5%, California’s real raise is only about +0.6% — still a gain, but far thinner than the 5% offer letter.
On our $100k single-filer model, a 3% raise produces after-tax growth below 3.5% in every state — so real raise is negative everywhere.
BLS ECI private industry wages rose only 3.1% over the year ending June 2026, and constant-dollar wages fell 0.4% (USDL-26-1270).
California needs roughly a 4.3% nominal raise at $100k just to clear CPI after tax on this model; no-wage-tax states clear slightly sooner.
Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, Wyoming levy no wage income tax, so their after-tax raise percentages match on this federal + FICA model.
Washington still taxes some capital gains (Tax Foundation 2026), but wage ladders here treat it like other no-wage-tax states.
A paycheck win still is not a full budget win — sales tax, property tax, and housing can offset income-tax savings.

A 5% offer letter is not a 5% raise in take-home. Share the after-tax and real % from your state page.
With CPI-U at 3.5%, a 3% COLA is a real cut on our $100k model in every state.
At $100k single, real growth starts around 4% nominal in Texas and 4.3% in California on this engine.

Employee FICA is 6.2% + 1.45% on most of a mid-career raise (IRS Topic 751) — before state tax.
BLS ECI private wages rose 3.1% YoY through June 2026; constant-dollar wages fell 0.4%. A raise near that median may still lose purchasing power after tax.
