Idaho Payroll Requirements: What Employers Need to Know in 2026

Idaho payroll uses a flat 5.8% state income tax rate, which applies to all taxable wages for Idaho residents and non-residents earning income in the state. Idaho moved to the flat rate structure in recent years, replacing a seven-bracket graduated system. Employers withhold at this rate each pay period and file quarterly withholding returns using the 910 withholding coupon with the Idaho State Tax Commission. Employers with larger withholding liabilities may be required to remit on a monthly basis, while smaller employers can stay on a quarterly schedule.

Idaho's State Unemployment Insurance taxable wage base is among the highest in the country — $53,500 per employee in 2026, placing Idaho fifth nationally for SUI wage base size. New employers pay a rate of 1.231% on that base, for a maximum first-year obligation of $658.59 per worker. While the rate itself is relatively low, the high wage base means the SUI contribution applies to a much larger portion of each employee's annual earnings than in states with $7,000 or $8,000 bases. The Idaho Department of Labor administers the SUI program and quarterly wage reports. Learn how Idaho SUI experience rates are assigned and what the high wage base means for multi-state employer cost comparisons.

Idaho's minimum wage is $7.25 per hour, the federal minimum, as the state has not enacted a higher state minimum. All covered employers in Idaho pay at least $7.25 regardless of industry or employer size. Idaho allows a tip credit: tipped employees may receive a direct cash wage of $3.35 per hour, provided tips bring total hourly compensation to at least $7.25. If tips fall short during any workweek, the employer must make up the difference out of pocket. Idaho has no state paid family and medical leave program and no state disability insurance tax in 2026.

Final paycheck rules in Idaho follow a demand-based model for discharged employees. When an employer terminates a worker, the final paycheck is due within 10 business days after the employee makes a written demand, or on the next regularly scheduled payday — whichever comes first. For employees who resign, the final check is due on the next regular payday. The demand requirement means the clock does not start running until the employee requests their wages in writing, which can create confusion when employers assume payment is automatically triggered by the termination date. Review Idaho payday law requirements including proper demand procedures, allowable deductions, and penalties for late payment.

New hire reporting in Idaho must be submitted within 20 days of the employee's first day of work to the Idaho Department of Health and Welfare Child Support Services. Reports may be filed online through the Idaho New Hire Reporting website. Required information includes the employee's name, address, Social Security number, date of hire, and the employer's name, address, and federal EIN. Idaho has no state-level local income taxes, which keeps the withholding picture straightforward — one state rate applies regardless of where in Idaho an employee lives or works.

For employers new to Idaho payroll, registration involves two primary agencies: the Idaho State Tax Commission for income tax withholding and the Idaho Department of Labor for SUI. Both registrations can be initiated online. The high SUI wage base is the most significant payroll cost factor that surprises out-of-state employers expanding into Idaho — the annual per-employee SUI cost at the new employer rate exceeds what many employers are accustomed to paying in lower-base states. See the full Idaho new employer registration guide with step-by-step instructions for both the tax commission and labor department accounts.
