Idaho Income Tax Overview (2025)
Idaho’s tax system is too simple, thanks to its flat income tax structure. In 2025, Idaho imposes a flat income tax rate of 5.695% on all taxable income, regardless of income level, marital status, or filing status. This straightforward approach benefits Idahoans by making tax calculations predictable and uniform across the Gem State. Here’s a deeper dive into Idaho’s income tax rules:
Flat Tax Rate: The 5.695% rate applies to all filers—single, married, or head of household—after accounting for deductions and credits. It eliminates the complexity of income tax brackets found in other states.
No Local Income Taxes: Unlike states with city or county taxes, Idaho’s tax burden remains consistent whether you live in Boise, Nampa, Idaho Falls, or rural areas.
Deductions and Credits: Idahoans can reduce their taxable income with deductions for dependents, charitable contributions, or other adjustments. Tax credits are available for parents, low-income filers, and certain business expenses, which can lower your tax bill significantly.
Special Considerations: Factors like household income, number of dependents, and filing status (e.g., head of household) can influence your tax liability. For example, claiming dependents may qualify you for Idaho’s child tax credit, reducing your state taxes.
Resources for Idahoans: The Idaho State Tax Commission offers tax tables, Form 967 for withholding reconciliation, and detailed guidance on filing status, exemptions, and income tax credits.
This flat tax system simplifies payroll calculations for both employees and employers, but understanding how deductions and credits apply can maximize your take-home pay. Use our Idaho paycheck tax calculator to see how Idaho’s tax rules affect your net income.
Federal Payroll Taxes Withheld in Idaho
In addition to Idaho state taxes, your paycheck includes federal payroll taxes, which are consistent across the U.S. These taxes reduce your gross pay to calculate your net pay. Here’s a comprehensive breakdown:.
Federal Income Tax
Based on your W-4 form, this tax depends on your income level, filing status (single, married, head of household), and withholding allowances. The IRS provides withholding tables to determine the amount. For example, a single filer earning $50,000 annually with no dependents will have higher withholdings than a married filer with two dependents.
FICA Taxes (Federal Insurance Contributions Act):
Social Security Tax: 6.2% of your wages, up to a 2025 wage base limit (approximately $168,600, adjusted annually). For a $60,000 salary, you’d pay $3,720 annually in Social Security tax.
Medicare Tax: 1.45% of all wages, with no income cap. On a $60,000 salary, this equals $870 annually.
Additional Medicare Tax: High earners (over $200,000 for single filers or $250,000 for married filing jointly) pay an extra 0.9% on income above these thresholds. For example, a single filer earning $250,000 pays $450 in Additional Medicare Tax on the $50,000 above the threshold.
FUTA (Federal Unemployment Tax Act):
Employers pay this tax (6% on the first $7,000 of each employee’s wages) to fund unemployment programs. It’s not withheld from your paycheck but is part of employer payroll responsibilities.
These taxes can significantly impact your take-home pay, especially for high earners or those with minimal deductions. Our Idaho paycheck tax estimator ensures these withholdings are accurately calculated, giving you a clear picture of your net pay.
Common Pre-Tax and Post-Tax Deductions
Deductions are a critical factor in determining your paycheck size. They’re divided into pre-tax (taken before taxes) and post-tax (taken after taxes). Here’s an expanded table of common deductions:
| Type | Examples | Impact |
|---|---|---|
| Pre-Tax | 401(k), Roth 401(k), health insurance, HSA, FSA, dental/vision plans, commuter benefits | Lowers taxable income, reducing federal and Idaho state tax liability |
| Post-Tax | Loan repayments, wage garnishments, union dues, child support, charitable donations, professional memberships | Reduces net pay after taxes are calculated |
Pre-tax deductions
Contributions to benefit accounts like a 401(k), health savings account (HSA), or flexible spending account (FSA) reduce your taxable income. For example, contributing $200 per pay period to a 401(k) lowers your taxable income by $200, saving you approximately $11.39 in Idaho state taxes (at 5.695%) and additional federal savings. Other pre-tax deductions, like health insurance premiums or commuter benefits, further reduce your tax liability, boosting your take-home pay indirectly.
Post-tax deductions
Expenses like court-ordered child support, loan repayments, or union dues are deducted after taxes, directly reducing your net pay. For instance, a $100 post-tax deduction lowers your take-home pay by $100. Wage garnishments, such as those for unpaid debts or child support, are also post-tax and can significantly impact your paycheck size.
Additional Deductions
Additional deductions, like fringe benefits (e.g., employee wellness programs, tuition reimbursement, or company-provided meals), may be pre-tax or post-tax depending on IRS rules. Our Idaho paycheck deduction calculator helps you visualize how these deductions, along with health care costs or retirement contributions, affect your net pay.
Hourly vs. Salaried Paychecks in Idaho
Your pay type—hourly or salaried—shapes how your paycheck is calculated in Idaho. Here’s a detailed comparison to help you understand the differences:
Hourly Employees:
Paid based on hours worked, ideal for variable schedules, part-time workers, or those in industries like retail, hospitality, or construction.
Eligible for overtime pay under the Fair Labor Standards Act (FLSA), which mandates time-and-a-half (1.5x regular rate) for hours over 40 per week. For example, a $25/hour worker in Twin Falls working 45 hours earns $1,000 regular pay + $187.50 overtime = $1,187.50 gross pay.
Bonuses or commissions are common in sales or service roles and are taxed as regular income, though employers may withhold supplemental wages at a flat federal rate (e.g., 22%).
Idaho follows federal overtime laws, with no additional state-specific rules, ensuring consistency for hourly workers across the Gem State..
Salaried Employees:
Receive a fixed annual salary, divided by pay frequency (e.g., $60,000/year ÷ 26 biweekly periods = $2,307.69 per paycheck).
May be exempt from overtime under FLSA rules if classified as exempt (e.g., managers, professionals, or administrative roles above a salary threshold, approximately $43,888 in 2025).
Non-exempt salaried employees are eligible for overtime, calculated based on their equivalent hourly rate (annual salary ÷ 2,080 hours for a 40-hour workweek).
Salaried employees often have more predictable paychecks but may include deductions for benefits like health insurance or retirement accounts.
Whether you’re an hourly worker earning overtime or a salaried employee with a 401(k), our Idaho paycheck calculator for hourly workers or salaried employees handles both scenarios, factoring in all relevant variables to estimate your net pay accurately.
Example Paycheck Calculations
To illustrate how the Idaho Paycheck Calculator works, here are three detailed scenarios for 2025, covering diverse worker profiles in Idaho:
Scenario 1: Hourly Worker with Overtime
Profile: $20/hour, 45 hours/week, single filer, 1 dependent, biweekly pay, $100 biweekly 401(k) contribution, $50 health insurance.
Gross Pay: (40 hours x $20) + (5 hours x $30 overtime) = $950
Federal Taxes (estimated): $110 (adjusted for 1 dependent, based on IRS withholding tables)
Idaho State Tax: ($950 – $150 pre-tax) x 5.695% = $45.56
FICA Taxes:
Social Security: $950 x 6.2% = $58.90
Medicare: $950 x 1.45% = $13.78
Pre-Tax Deductions: $100 (401(k)) + $50 (health insurance) = $150
Taxable Income: $950 – $150 = $800
Net Pay: $950 – $110 – $45.56 – $58.90 – $13.78 – $150 = $571.76
Scenario 2: Salaried Employee with Dependents
Profile: $60,000/year, married filing jointly, 2 dependents, biweekly pay, $200 biweekly health insurance, $150 HSA contribution.
Gross Pay: $60,000 ÷ 26 pay periods = $2,307.69
Federal Taxes (estimated): $250 (adjusted for 2 dependents and married status)
Idaho State Tax: ($2,307.69 – $350 pre-tax) x 5.695% = $111.48
FICA Taxes:
Social Security: $2,307.69 x 6.2% = $143.08
Medicare: $2,307.69 x 1.45% = $33.46
Pre-Tax Deductions: $200 (health insurance) + $150 (HSA) = $350
Taxable Income: $2,307.69 – $350 = $1,957.69
Net Pay: $2,307.69 – $250 – $111.48 – $143.08 – $33.46 – $350 = $1,619.67
Scenario 3: High-Earning Salaried Employee
Profile: $150,000/year, single filer, no dependents, monthly pay, $500 health insurance, $300 401(k), $100 post-tax child support.
Gross Pay: $150,000 ÷ 12 = $12,500
Federal Taxes (estimated): $2,200 (based on IRS tables for high earners)
Idaho State Tax: ($12,500 – $800 pre-tax) x 5.695% = $666.62
FICA Taxes:
Social Security: $12,500 x 6.2% = $775 (capped at wage base)
Medicare: $12,500 x 1.45% = $181.25
Additional Medicare: ($150,000 – $200,000 threshold = $0, so none applies)
Pre-Tax Deductions: $500 (health insurance) + $300 (401(k)) = $800
Post-Tax Deduction: $100 (child support)
Taxable Income: $12,500 – $800 = $11,700
Net Pay: $12,500 – $2,200 – $666.62 – $775 – $181.25 – $800 – $100 = $7,977.13
These scenarios demonstrate how taxes, deductions, and pay types affect your take-home pay. Use our Idaho paycheck calculator with state tax to run your own numbers and plan accordingly.
Idaho Employer Payroll Responsibilities
Employers in Idaho, from small business owners in Nampa to large corporations in Boise, have several payroll obligations to ensure compliance with state and federal regulations:
Tax Withholding: Withhold federal income tax, Social Security, Medicare, and Idaho state income tax based on employees’ W-4 and Idaho Form ID W-4. Accurate withholding prevents penalties and ensures employees’ tax liabilities are met.
Tax Filing:
File Form 941 (quarterly federal tax return) with the IRS to report withheld taxes.
Submit Form 967 (Idaho Annual Withholding Reconciliation) to the Idaho State Tax Commission.
Pay FUTA (Federal Unemployment Tax Act) and SUTA (State Unemployment Tax Act) to fund unemployment programs. Idaho’s SUTA rates vary based on industry and experience rating.
Workers’ Compensation: Required by the Idaho Department of Labor, this insurance covers workplace injuries and is mandatory for most employers.
Payroll Records: Maintain accurate payroll stubs, including wages, taxes, deductions, and payment frequencies, for compliance and employee transparency.
Additional Responsibilities: Issue Form W-2 (Wage and Tax Statement) annually, report new hires to the Idaho Department of Labor, and ensure compliance with FLSA overtime rules.
Using payroll software or consulting an accountant can streamline these tasks, especially for complex pay schedules, fringe benefits, or incentive payments like bonuses. Our Idaho paycheck calculator can also help employers estimate employee net pay for better payroll planning.
