Take-home pay on a $120,000 salary in Idaho

What applies to you at $120,000, and what does not

The mortgage-insurance deduction has just closed

PMI is deductible as interest for itemizers only below $109,000 of AGI, phasing down from $100,000 at 10.0% per $1,000. $120,000 is above the end of that window, so the deduction is worth nothing here however much PMI you pay. It is one of the few thresholds on this ladder that closes completely inside a $9,000 span of income.

Moving up from $120,000, and how you got here

Getting here from $100,000 meant a $20,000 rise, of which $13,010 landed in your account — 65.0%. Leaving for $150,000 would mean another $30,000, and this time $18,951 a year reaches you, $1,579 a month, 63.2% of it. No point on either ladder pays you less for earning more: each rate applies only to the slice of income inside its own band.

$120,000 against Idaho's own schedule

Idaho taxes a single filer through two bands. $120,000 reaches the second of them, so the top slice of your Idaho taxable income ($103,900 after the $16,100 Idaho takes off first) is charged at 5.3%. Nothing is published above it. Of the $103,900 Idaho taxes, $99,089 — 95.4% — falls in this last band and the rest in the band below it. This is the last band Idaho publishes and it has no upper edge, so the rate on further income does not move again however much more you earn. Below it, $4,811 escaped Idaho's tax entirely, which puts the effective rate on the whole salary — 4.4% — 0.92 of a percentage point under the 5.3% headline.

There is no band above this one, so where you sit inside it changes nothing.

What the top of your federal bill is actually taxed at

The next dollar at $120,000 is charged in the band directly above the largest rate step in the whole schedule. Crossing that particular edge costs more than crossing any other, which is why a pay rise around this level so often lands lighter in the bank than it looked on the letter. The band still has $1,800 of headroom, which is about $1,800 of raise before a higher rate touches any part of it.

$120,000 still gets the tips and overtime deductions in full

If part of your pay is tips or FLSA overtime premium, OBBBA lets you deduct up to $25,000 of tips and $12,500 of overtime premium without itemizing, and the phase-out does not begin until $150,000 of modified AGI. $120,000 is $30,000 below that line, so both survive intact. They cut income tax only — Social Security and Medicare are charged on that income regardless.

If you pay for childcare, $120,000 sets your credit rate

The Child and Dependent Care Credit pays a percentage of qualifying care costs, up to $3,000 of expenses for one dependent and $6,000 for two or more, and that percentage is set by your income. At $120,000 it is 20.0%: you are at the floor. The rate cannot fall below 20.0% however much more you earn, so unlike most things on this page, further raises cost you nothing here. The credit is nonrefundable and is not modelled in the take-home figures above, which assume no dependents.

If you are 65 or over, $120,000 has already cut your senior deduction

OBBBA's $6,000-per-person senior deduction starts shrinking above $75,000 of modified AGI, at 6.0% of every dollar over the line. At $120,000 you are $45,000 into that phase-out, leaving roughly $3,300 of the deduction, and it disappears entirely at $175,000. The figures on this page do not include it — they model a filer under 65 — but it is the one deduction at this income level that a raise quietly erodes.

$120,000 beside the Idaho minimum wage

The minimum wage in Idaho is $7.25 an hour, which is $15,080 a year at forty hours a week. $120,000 is 8.0 times that. Run the floor through the same engine and it keeps $13,926 of that $15,080 — 7.7% withheld — against 26.7% at $120,000. The gap between those two shares is the graduated system doing its work: the extra $104,920 of gross is charged at higher rates than the first $15,080 ever is.

Idaho's minimum wage equals the federal floor of $7.25/hour, with no separate state minimum or inflation adjustment for 2026.

$120,000 is inside the car-loan interest phase-out

The OBBBA deduction for interest on a qualifying new-vehicle loan is capped at $10,000 and shrinks by $200 for every $1,000 of modified AGI above $100,000, counting any part of $1,000 as a whole one. At $120,000 you are $20,000 past that line, so roughly $6,000 of the allowance survives, and it is gone by $150,000. This is a deduction, not a credit, so what it is actually worth to you is that figure times your federal marginal rate.

Where Idaho ranks on $120,000

Run the same $120,000 through all fifty states and the District of Columbia and Idaho comes 31 from the top on take-home pay — 21 from the bottom — keeping $87,998. The jurisdictions immediately above it at this salary are Rhode Island and Georgia; immediately below are South Carolina and Utah. Texas tops the table at $93,250, $5,252 more than Idaho on identical gross pay, and Oregon is last at $83,249. That ranking is specific to $120,000: flat-rate and graduated states change places as income rises, so Idaho's neighbours on this table are different at other salaries.

A bonus is withheld differently from a raise in Idaho

Idaho withholds supplemental wages — a bonus, a commission, a payout — at a flat 5.3%, not at the rate the rest of your pay is charged. That is exactly the rate your salary is charged at this rung, so a bonus and a raise are withheld identically here. On $1,000 of bonus it is the difference between $53.00 and $53.00 of Idaho withholding. Withholding is not the tax: what you owe is settled on the return either way.

Does Idaho follow the tips and overtime deductions?

The tips and overtime deductions described on this page are federal. On the state return Idaho treats them alike: it follows the federal tips and overtime deductions.

Idaho starts from federal taxable income and conformed via HB559 (2026), retroactive to 2025 — the deductions flow through.

How this figure was computed

All of the figures on this page come out of the same open paycheck engine the Idaho calculator uses, run against the 2026 tax data file in this repository at build time — not typed in, not lifted from anyone else's table.

Gross

$120,000 a year, spread evenly: $57.69 an hour, $4,615.38 a fortnight.

Federal

2026 brackets on $103,900 taxable (gross less the $16,100 standard deduction), Rev. Proc. 2025-32 → $17,570.

FICA

Social Security $7,440 on all of $120,000, under the $184,500 base. Medicare $1,740.

Idaho

Its own schedule on $103,900 after the $16,100 Idaho subtracts first, through two bands → $5,252.

What this does not include

• Not in the arithmetic. Pre-tax deductions (401(k), HSA, FSA, premiums), dependents and credits, itemizing, non-wage income, and the employer's half of FICA. Idaho has no local wage income tax, so nothing is missing on that line.
• What is specifically live at $120,000. None of the following is in the take-home figure above, and all of it is real at this income: the partially phased-out senior deduction (if you are 65 or over); the partially phased-out new-vehicle loan interest deduction; the Child and Dependent Care Credit, whose rate at this income is set by the §21 schedule described above.
• Local income taxes are not included.
• Idaho charges a $10 Permanent Building Fund tax per return, which this calculator does not include.
• Idaho's grocery credit, now called the food tax credit, is $155 per person, or up to $250 with receipts for sales tax paid on food. You claim it on your Idaho return, so it is not included in this estimate.

A computed estimate, not tax advice. Your own W-4, benefits and credits move the number.
