This flat rate applies to most residents, part-year residents, and nonresidents with Idaho-sourced income, making state filing straightforward compared to progressive systems in other states.

Whether you're a single filer, married filing jointly, or have additional income sources, TurboTax handles Idaho state taxes seamlessly alongside your federal return.

Main Ways to Deduct on Idaho Returns

1. Standard Deduction (most common — automatic for many filers)

• Idaho allows the federal standard deduction (increased for 2025 due to conformity).

• Approximate 2025 amounts (inflation-adjusted/conformed):

• Single or Married Filing Separately: Around $15,750–$16,100

• Married Filing Jointly: Around $31,500–$32,200

• Head of Household: Around $23,625

• The Idaho State Tax Commission automatically applies the larger amounts for standard deduction users on Form 40/43. No extra steps needed for most.

2. Itemized Deductions

• If higher than the standard, itemize on your Idaho return (similar to federal Schedule A, but with Idaho adjustments).

• Common items: Mortgage interest, charitable contributions, medical expenses (>7.5% of AGI), real estate taxes (subject to any state limits).

• Note: State and local income/sales taxes may have federal SALT-like caps, but Idaho conforms closely.

3. Idaho-Specific Subtractions (from Form 39R, Part B — these reduce AGI before deductions) Common ones include:

• Contributions to the IDeal College Savings Program (up to $6,000 single / $12,000 married filing jointly).

• Health insurance premiums (if not claimed federally).

• Medical Savings Account contributions (up to $10,000 single / $20,000 joint).

• Deduction for support of home for aged or disabled relative ($1,000 per qualifying family member).

• First-time home buyer savings account contributions (up to $15,000 single / $30,000 joint).

• Active duty military pay (not taxed in Idaho).

• Other subtractions, like certain retirement income or federal conformity items.

4. New 2025 Conformity Deductions (claim via updated Form 40 line 18 or Form 43 line 40 instructions; may use Worksheet 1-A for nonresidents)

• No tax on qualified tips from wages.

• No tax on overtime compensation (for eligible workers).

• Car loan interest deduction (qualified amounts).

• Enhanced senior deduction (extra for those 65+). These are in addition to the standard deduction for many filers. Use the latest instructions (updated March 2026) from tax.idaho.gov to claim on existing lines — no new form fields added.

Popular Idaho Credits (separate from deductions — these reduce tax owed directly)

• Food Tax Credit (formerly Grocery Credit) — helps offset sales tax on food.

• Idaho Child Tax Credit (for qualifying children under 17).

• Educational Charities Credit, Youth and Rehabilitation Credit, etc.

• Parental Choice Tax Credit (application-based; notifications by April 15, 2026).

For the most accurate details, download the latest Form 40 Instructions (2025) and Popular Credits and Deductions list from the official Idaho State Tax Commission site: tax.idaho.gov. Rules can vary by residency (resident, part-year, nonresident), and software like TurboTax (via InstallTurboTax.com) automatically handles these with updates for 2025 conformity changes.
