How the Idaho Paycheck Calculator Works
This tool uses the annualization method to estimate your Idaho take-home pay. Here is exactly what happens when you click Calculate:
-
Gross pay is calculated
For salary workers, your annual salary is divided by your pay frequency. For hourly workers, your rate is multiplied by weekly hours and then annualized.
-
Pre-tax deductions are subtracted
401(k), health insurance, FSA, and HSA contributions are removed before any income tax is calculated, lowering your federal and Idaho taxable income.
-
Federal income tax is calculated
Your annualized taxable income is run through the 2026 IRS Publication 15-T federal withholding tables. Any withholding allowances from your W-4 are deducted first. The result is divided by your pay periods for a per-paycheck amount.
-
Idaho state income tax is calculated
Idaho uses a simplified flat structure: the first approximately $4,950 (single) or $9,900 (married filing jointly) of taxable income is exempt. Everything above that is taxed at a flat 5.3%. Idaho Form A-4 allowances reduce the amount subject to state withholding. The annual state tax is divided by your pay periods.
-
FICA taxes are calculated
Social Security is withheld at 6.2% on wages up to $176,100. Medicare is withheld at 1.45% on all wages, with an extra 0.9% applied to wages above $200,000 ($250,000 for married filing jointly). Section 125 benefits like health insurance and FSA/HSA reduce your FICA-taxable wages.
-
Net pay is calculated
All taxes and deductions are subtracted from gross pay to produce your estimated Idaho take-home pay per paycheck and per year.
Idaho State Income Tax in 2026
Idaho reformed its income tax structure in 2022 with House Bill 436, replacing a seven-bracket graduated system with a simplified near-flat approach. For 2026, Idaho taxes income above an annually indexed exempt amount at a flat rate of 5.3%. The exempt amount is indexed each year using a cost-of-living formula set by the Idaho State Tax Commission.
The exempt amount for 2025 was $4,811 for single filers and $9,622 for married filing jointly, per the Idaho State Tax Commission rate schedule. The 2026 figures are indexed upward and are estimated at approximately $4,950 (single) and $9,900 (married). Actual figures are published annually by the Idaho Tax Commission on Form IDW-4 and Form A-4 instructions.

Idaho Has No Local Income Tax
Unlike states such as Ohio and Pennsylvania where many cities levy a local wage tax, Idaho has no city or county income tax on wages. Your Idaho paycheck involves only federal income tax, Idaho state income tax, and FICA deductions. This makes Idaho a relatively clean and straightforward state for paycheck calculations. If you compare your Idaho pay to a paycheck from a city in Oregon or California, you may notice a meaningful difference in local deductions.
Idaho Minimum Wage and Overtime Rules
Idaho's minimum wage is $7.25 per hour in 2026, matching the federal floor. Tipped employees may receive a base of $3.35 per hour, provided total compensation including tips equals at least $7.25 per hour. Idaho follows the federal Fair Labor Standards Act for overtime: hours worked beyond 40 in a workweek must be paid at 1.5 times the regular rate. Idaho does not have a daily overtime rule. You can estimate overtime pay impact with our overtime calculator or our time-and-a-half calculator.
Federal Income Tax Withholding in 2026
The federal tax brackets used by employers for 2026 withholding come from IRS Publication 15-T. They range from 10% to 37% based on annualized income and filing status. Our federal tax calculator shows this breakdown in detail. You can also explore how your deductions work with our pre-tax deduction calculator.
2026 FICA Taxes: Social Security and Medicare
Social Security is withheld at 6.2% on wages up to the 2026 wage base of $176,100, per the Social Security Administration. Once your year-to-date earnings pass that threshold, Social Security withholding stops for the rest of the year. Medicare is withheld at 1.45% on all wages with no cap. Workers earning above $200,000 (single) or $250,000 (married filing jointly) pay an additional 0.9% Medicare surtax under IRC Section 3103. Use our dedicated FICA tax calculator to model these amounts separately.
Idaho Form A-4: State Withholding Certificate
Idaho employees use Form A-4 to declare their state withholding allowances with their employer. More allowances mean less Idaho income tax withheld per paycheck, but you may owe at tax time if you claim too many. New employees who do not submit a Form A-4 are typically withheld at the single-zero allowance rate by default. Check your current A-4 filing with your employer's payroll department if your withholding seems off. Our tax withholding calculator can help you decide how many allowances to claim.

Idaho Paycheck Calculator: Frequently Asked Questions
Idaho uses a near-flat income tax system for 2026. The first $4,950 of taxable income for single filers (approximately $9,900 for married filing jointly) is taxed at 0%. All income above that threshold is taxed at a flat 5.3%. This simplified structure replaced Idaho's old seven-bracket graduated system in 2022 under House Bill 436.
No. Idaho does not have any city or county-level income tax on wages. Your Idaho paycheck deductions are limited to federal income tax, Idaho state income tax, and FICA (Social Security and Medicare). Cities like Boise, Meridian, and Nampa do not add any local wage tax.
The Social Security taxable wage base for 2026 is $176,100, per the Social Security Administration. Employees pay 6.2% on wages up to that cap. Once your year-to-date earnings cross that threshold, Social Security withholding stops for the remainder of the year. There is no cap on Medicare, which is withheld at 1.45% on all wages.
Pre-tax deductions such as traditional 401(k) contributions, health insurance premiums, HSA contributions, and FSA contributions reduce your taxable income for both federal and Idaho state income tax purposes. This means contributing pre-tax lowers both your federal and Idaho state withholding simultaneously. Section 125 plan benefits (health, FSA, HSA) also reduce your FICA-taxable wages, providing an additional savings on Social Security and Medicare taxes. Use our paycheck after 401(k) calculator to model this specifically.
Idaho Form A-4 is the Idaho Employee's Withholding Allowance Certificate. You give this form to your employer to set your Idaho state income tax withholding. Each allowance reduces the amount of Idaho tax withheld from your paycheck. If you do not submit this form, your employer typically withholds at the single zero-allowance rate, which may result in a refund at tax time. You can update your A-4 at any time by submitting a new form to your payroll department.
Idaho's minimum wage is $7.25 per hour in 2026, which matches the federal minimum wage. Idaho has not enacted a state-specific minimum wage above the federal floor. Tipped employees can be paid a base of $3.35 per hour, provided total compensation including tips reaches at least $7.25 per hour. Employees under 20 years old may be paid a training wage of $4.25 per hour for the first 90 calendar days of employment.
Idaho employers use the annualization method for withholding. Your per-period wages are annualized based on pay frequency. The Idaho exempt amount is subtracted based on filing status. Idaho Form A-4 allowances are then subtracted. The flat 5.3% rate is applied to the remaining taxable amount. The resulting annual Idaho tax is divided by your number of pay periods to get your per-paycheck withholding amount.
