Idaho paycheck, explained

A Idaho paycheck calculator shows what you actually keep from your salary after every mandatory withholding. Idaho charges a flat 5.3% state income tax on top of federal tax and FICA, so every dollar of taxable income above the standard deduction is taxed at the same rate regardless of how much you earn. This tool estimates federal income tax, Idaho state income tax, and FICA payroll tax, then divides your net pay across your chosen pay schedule.

Idaho's flat-rate system means your marginal and effective state tax rate are nearly identical, unlike progressive states where they diverge as income rises. Enter your gross salary above to see your Idaho take-home pay per paycheck.

Idaho income tax

Idaho uses a flat 5.3% income tax rate on taxable income. The state standard deduction is $16,100 for single filers and $32,200 for joint filers, which reduces the income subject to state tax.

There are no additional local or county income taxes in Idaho; the state rate above is the only income tax withheld from a paycheck. Idaho does not tax Social Security retirement benefits.

The paycheck formula

A paycheck calculator works backward from your gross salary, removing every mandatory withholding to reveal your true take-home pay:

taxable income = gross salary − pre-tax deductions − standard deduction
federal tax = progressive federal brackets
Idaho tax = 5.3% flat rate on taxable income above the standard deduction
FICA = 6.2% Social Security (to cap) + 1.45% Medicare
net pay = gross − federal − state − FICA − pre-tax deductions
per paycheck = net pay ÷ number of pay periods

Worked example

Federal income tax is roughly $8,770, FICA is $6,120, and Idaho state income tax is about $3,132 at the flat 5.3% rate after the standard deduction. Net take-home is around $61,978 a year, close to $2,384 every two weeks on a bi-weekly schedule. Contributing to a 401(k) or HSA would lower both federal and state tax and raise the after-tax value of saving.

How Idaho compares

On the same $80,000 single salary, Idaho take-home is about $61,978 — $3,132 less than Texas's $65,110 (Texas has no state income tax), $462 more than California's $61,516, and $663 more than New York's $61,315. The chart above shows how Idaho stacks up against those three benchmark states on identical pay.
