How Idaho taxes your paycheck in 2026
Idaho has a flat 5.3% income tax rate (converted from progressive in 2023).
When you look at your Idaho paycheck, you'll see several deductions: federal income tax (withheld based on your W-4 and filing status), FICA (Social Security at 6.2% and Medicare at 1.45%), and a flat 5.30% Idaho state tax on your taxable income.
Federal tax brackets for 2026
Before your Idaho tax, the IRS takes federal income tax. The 2026 federal brackets (for a single filer, Rev. Proc. 2025-32) are:
| Income range | Rate |
|---|---|
| $0 – $12,400 | 10% |
| $12,400 – $50,400 | 12% |
| $50,400 – $105,700 | 22% |
| $105,700 – $201,775 | 24% |

| $256,225 – $640,600 | 35% |

Standard deduction (federal)
For tax year 2026, the federal standard deduction is $16,100 for single filers and $32,200 for married filing jointly.
FICA tax breakdown
- Social Security: 6.2% of wages up to $184,500 (2026 wage base)
- Medicare: 1.45% on all wages, with no cap
- Additional Medicare: 0.9% on wages over $200,000 (single) or $250,000 (MFJ)
FICA is a federal tax, so your Idaho rate is identical to every other state. Your employer pays a matching 6.2% + 1.45% for you (self-employed workers pay both halves).
