Idaho Income Tax Rates 2026
Idaho dramatically simplified its tax system in 2023, moving from a multi-bracket structure to a single flat rate. This makes Idaho paycheck calculations among the most straightforward in the country.

Key advantage of Idaho's flat tax: Because it's a single rate, there's no "bracket creep" — earning more doesn't push you into a higher state bracket. Every dollar of Idaho taxable income above the standard deduction is taxed at exactly 5.3%. Idaho also conforms to the federal standard deduction, so any increase in the federal standard deduction automatically reduces your Idaho tax burden as well.

Section 3
How Idaho Paycheck Tax Is Calculated
Idaho's flat tax simplifies the payroll math considerably. Here is the complete step-by-step calculation your employer's payroll system follows each pay period — the same sequence that shows up on your pay stub.
1
Compute Gross Pay
Hourly: rate × hours in period. Salary: annual ÷ periods. Idaho follows federal FLSA overtime at 1.5× for hours over 40/week. No daily overtime. Idaho's minimum wage matches the federal floor of $7.25/hour — employers in Idaho must pay at least this amount for all non-exempt employees.
2
Subtract Pre-Tax Benefit Deductions
401(k), health premiums, HSA, and FSA contributions are subtracted before tax calculations. Since Idaho conforms to federal AGI, these deductions reduce both your federal and Idaho taxable income. This creates compounding savings — every pre-tax dollar saves you 5.3% in Idaho tax + your marginal federal rate + 7.65% in FICA.
3
Federal Withholding (IRS Percentage Method)
Based on your W-4 and 2026 IRS Publication 15-T tables. Idaho workers earning $40,000–$80,000 typically fall in the 12%–22% federal brackets. The federal standard deduction ($16,100 single / $32,200 MFJ for 2026) is applied before bracket calculation.
4
FICA: Social Security + Medicare
Social Security: 6.2% on wages up to $184,500. Medicare: 1.45% on all wages (no cap). Additional 0.9% Medicare on wages over $200,000. No Idaho-specific FICA modifications.
5
Idaho State Tax: Simple Flat Rate Calculation
Idaho's flat 5.3% applies to your annual taxable income after the Idaho standard deduction. Your employer annualizes your per-paycheck wages, subtracts the deduction, applies 5.3%, then divides by your pay periods. Because it's flat, there is no complex bracket computation needed — Idaho state withholding is more predictable and easier to verify than most states.
6
Post-Tax Deductions → Your Net Pay
Subtract Roth 401k, garnishments, and any post-tax items. Idaho law requires wages be paid at least monthly. The Idaho Payment of Wages Law (Idaho Code § 45-601 et seq.) governs all paycheck timing and deduction rules for Idaho employers.
Section 4
Pre-Tax Deductions That Boost Your Idaho Take-Home Pay
Because Idaho's flat tax rate applies to every dollar of taxable income, reducing your taxable income through pre-tax deductions has a clear, predictable payoff. Here are the most impactful options for Idaho workers.
🏦
Traditional 401(k) — Clear Math, Real Savings
In Idaho, each $1,000 in 401(k) contributions saves exactly $53.00 in state income tax (5.3%), plus federal savings at your marginal rate, plus FICA savings. With the 2026 limit of $23,500, maxing your 401(k) could save an Idaho worker in the 22% federal bracket over $7,700/year in combined taxes. Idaho's flat rate makes this ROI crystal-clear — no guesswork about bracket impact.
2026 limit: $23,500Saves exactly 5.3% in ID tax50+ catch-up: +$7,500
🏥
Employer Health Plan Premiums
Health, dental, and vision premiums through a Section 125 plan are pre-tax — reducing gross wages before federal, state, and FICA calculations. Idaho has a relatively healthy workforce and competitive employer health plans, particularly in Boise's growing tech and healthcare sectors. Average employee premium contributions in Idaho run $120–$300/month for individual coverage.

Idaho-Specific Tax Credits to Know at Filing
While not paycheck deductions, Idaho offers credits that reduce your annual tax bill: the Idaho Grocery Credit ($120/person annually, $140 if age 65+) — a unique refundable credit for all Idaho residents regardless of income. There's also the Child Tax Credit add-on, Retirement Income Deduction for taxpayers 65+ (deduct up to $36,900 of retirement income), and credits for donations to Idaho educational entities. These affect your annual return, not per-paycheck withholding.
Grocery credit: $120/personRefundable for all residentsRetirement deduction at 65+
Idaho tax tip: Idaho has no estate or inheritance tax, no intangible personal property tax, and no local income taxes. Its tax structure is among the simpler in the Mountain West. However, Idaho's sales tax is 6% (one of the higher rates in the region), which partially offsets the income tax advantages. For net take-home calculation purposes, only the income tax and FICA affect your paycheck — sales tax is a separate consideration.
Section 5
Idaho Pay Frequency & Final Paycheck Rules 2026
Idaho gives employers flexibility on pay schedules, but state law still sets clear rules for when you must be paid — including the overtime rules covered in our guide to hourly and salaried pay.
💵
Idaho Wage Payment Act — Your Right to Be Paid On Time
Idaho Code § 45-601 et seq. requires Idaho employers to establish regular pay periods and pay wages within the time set by the employer. Unlike many states, Idaho does not mandate a specific minimum pay frequency — employers may pay weekly, bi-weekly, semi-monthly, or monthly as long as they maintain the schedule they establish. However, they cannot change the pay period without proper notice.
Final wages upon discharge must be paid within 10 days of the end of the pay period, or by the next regular payday — whichever is sooner. Employees who resign are entitled to final wages on the next regular payday. Idaho does not require payout of unused vacation unless the employer's written policy provides for it — see our final paycheck rules guide for how vacation payout works across states.

Flat tax advantage: Unlike progressive-tax states, Idaho workers can calculate their state tax liability in seconds — just multiply taxable income by 5.3%. A $10,000 raise always costs exactly $530 in additional Idaho state tax, regardless of your income level.
Section — Idaho Cities & Labor Markets
Boise, Nampa, Meridian & Idaho Labor Markets
Idaho has no city or county income taxes anywhere in the state. Every worker pays the same 5.3% flat state rate regardless of location. What varies by city is the dominant industry, average wages, and the major employers whose benefit programs shape your net pay.
💻
Boise
Ada County · ~240,000 pop. · Tech & healthcare hub
Boise anchors Idaho's economy and has become one of the fastest-growing tech cities in the Mountain West. Micron Technology (semiconductor manufacturing, 10,000+ employees statewide) is the state's largest private employer. Hewlett Packard Enterprise, Clearwater Analytics, and a growing startup ecosystem round out the tech sector. Healthcare employers — St. Luke's Health System and St. Alphonsus Regional Medical Center — are among Boise's largest. Tech wages average $80,000–$140,000; healthcare $55,000–$110,000. No Boise city income tax; only Idaho's 5.3% flat rate applies.

Nampa & Meridian
Canyon County · Boise metro overflow · Fast growth
Nampa and Meridian are among the fastest-growing cities in the U.S. — driven by outmigration from California and the Pacific Northwest. Nampa houses significant food processing (Amalgamated Sugar, Treasure Valley Food Hub) and light manufacturing alongside retail. Meridian has become a corporate office and healthcare hub — Blue Cross of Idaho, Saint Alphonsus, and numerous tech companies have campuses here. Average wages: manufacturing $38,000–$55,000; corporate/healthcare $55,000–$90,000. Same 5.3% flat Idaho rate applies.

Twin Falls & Magic Valley
Twin Falls County · Agriculture & food processing
Twin Falls is the commercial center of Idaho's Magic Valley — home to one of the most concentrated dairy and food processing economies in the U.S. Chobani (one of the world's largest yogurt plants), Clif Bar, and numerous dairy processors employ thousands. Manufacturing and processing wages average $35,000–$58,000. Chobani is known for offering equity ownership to employees — workers receiving profit-sharing or equity distributions have additional income that requires careful Idaho withholding planning. Agricultural workers on small farms may fall under FLSA agricultural exemptions.

Idaho Falls & Eastern Idaho
Bonneville County · Nuclear energy & research
Idaho Falls is home to the Idaho National Laboratory (INL) — the nation's leading nuclear energy research facility, operated by Battelle Energy Alliance with ~5,500 employees. INL scientists, engineers, and technicians earn $65,000–$160,000 with federal-contractor benefit packages including FERS retirement and TSP (treated as pre-tax for Idaho purposes). INL is a uniquely high-wage anchor for eastern Idaho — the area's labor market features wages significantly above state average. No local income tax applies; all workers pay 5.3% flat Idaho rate.

The Idaho migration dynamic: Idaho is one of the top destination states for Californians and Pacific Northwesterners fleeing high taxes — especially Oregon (9.9% top rate) and Washington (no income tax but rising cost of living). For an Oregon worker earning $100,000 who relocates to Idaho, the state income tax difference alone is approximately $4,200/year. Idaho's lower cost of living compounds this advantage. However, workers relocating from Washington (no income tax) to Idaho are moving to a higher-tax state — important to factor in for compensation negotiations.
Idaho's flat-tax approach is shared by two other states in our coverage: Utah, whose 4.45% rate is the lowest flat rate among them, and Illinois, which applies a 4.95% flat rate but adds no local income tax either. All three states calculate withholding the same simple way: one rate applied to every dollar, with no bracket math. For workers weighing a move to a state with zero income tax instead, Nevada eliminates the state tax line entirely. Our full breakdown of how these paycheck figures are calculated is available in our calculation methodology.
Take-Home Pay Guide
How Much Is Taken Out of My Paycheck in Idaho?
For a typical Idaho worker earning $60,000/year (bi-weekly), expect roughly $267 in federal income tax, ~$166 in Idaho state tax (5.3% flat), and ~$184 in FICA — leaving approximately $1,883 per paycheck. Idaho's flat tax makes the math consistent: every dollar of taxable income costs exactly 5.3 cents in state tax. A Micron Technology engineer earning $95,000 nets approximately $2,610 bi-weekly. Workers relocating from Oregon (9.9% top rate) see an immediate improvement of $3,900–$5,400/year in net pay at comparable salaries.

Idaho Salary Calculator — Annual Pay to Net Take-Home
Idaho's flat 5.3% rate makes salary-to-net conversion simpler than most states. Rough rule: subtract 26%–31% from gross bi-weekly pay at typical Idaho salaries ($50K–$100K) to estimate net take-home. The unique Idaho Grocery Credit ($120 per person annually, $140 if 65+) offsets some of the flat rate's impact on lower-income workers. Idaho's retirement income deduction (up to $36,900 for those 65+) makes it attractive for retirees moving from higher-tax Pacific Northwest states.
Answers to the top questions about Idaho take-home pay, state income tax, and payroll deductions. Updated for 2026.
Idaho has a flat state income tax rate of 5.3% for all filing statuses in 2026 (cut from 5.695% via HB 40, retroactive to January 2025). This applies to all taxable income above the standard deduction ($16,100 single / $32,200 married filing jointly). Idaho moved from a multi-bracket system (with a top rate of 6%) to a flat rate in 2023. The simplicity means Idaho workers can easily estimate their state tax — just multiply taxable income by 5.3%.
Example: A single Idaho worker earning $50,000/year bi-weekly would see approximately: Federal income tax: ~$3,400/yr (~$131/paycheck) | Idaho state tax: ~$1,797/yr (~$69/paycheck) at 5.3% | Social Security: ~$3,100/yr (~$119/paycheck) | Medicare: ~$725/yr (~$28/paycheck). Total taxes ~$9,022/yr, leaving a take-home of approximately $40,978/year or ~$1,576/bi-weekly paycheck. Use our calculator for your exact numbers.
No. Boise, Nampa, Meridian, Idaho Falls, Pocatello, and every other Idaho city has no local income tax. Idaho state law preempts local governments from levying income taxes. The only income taxes you pay as an Idaho worker are federal and state — making Idaho paycheck calculations simpler than states like Ohio, Pennsylvania, or Kentucky where hundreds of localities levy their own income taxes.
Boise has no local minimum wage — the applicable rate is Idaho's statewide minimum wage of $7.25 per hour, which equals the federal minimum. Unlike cities in Washington, Oregon, Colorado, and California that have set higher local minimums, Boise and all Idaho municipalities are bound by the state minimum. Idaho has not increased its minimum wage above $7.25 since 2009 when the federal floor was last raised. Tipped workers may be paid $3.35/hour in cash wages as long as tips bring them to $7.25/hr total.
Idaho law limits unauthorized paycheck deductions significantly. Employers may deduct taxes, court-ordered garnishments, and items you specifically authorize in writing (insurance, retirement contributions, etc.). Employers cannot deduct for cash register shortages, business losses, or broken equipment without your written consent — and even with consent, deductions that bring pay below minimum wage are prohibited. If your employer is making deductions you haven't authorized, you may have a wage claim under Idaho Code § 45-609.
Idaho's 5.3% flat rate compares as follows to neighboring states: Montana tops out at 5.65% (two brackets); Wyoming has no state income tax; Nevada has no state income tax; Utah also has a flat rate at 4.45% (lower than Idaho); Oregon tops out at 9.9% (much higher); Washington has no income tax. Idaho's rate is middle-of-the-road for the Mountain West — significantly better than Oregon but not as advantageous as Wyoming, Nevada, or Washington for high earners.
