- Maximize pre-tax contributions to 401(k) ($23,500 limit in 2026, $31,000 if 50+) to reduce both federal and ID state taxable income.
- Use an HSA if you have a high-deductible health plan. Contributions ($4,400 individual, $8,750 family) are pre-tax and reduce your tax burden.
- Review your W-4. If you regularly get large refunds, adjust your withholding to keep more money in each paycheck throughout the year.

If I work remotely in Idaho for an out-of-state employer, what tax do I pay?
As a Idaho resident working remotely for an out-of-state employer, the rules depend on reciprocity agreements. Reciprocity-pair states (PA-NJ, IL-IA, MI-OH, etc.) let you pay tax only to Idaho. Without reciprocity, you may pay tax to BOTH states, then claim a credit on Idaho's return for taxes paid to the work state. NY, PA-Philadelphia, and other "convenience of employer" jurisdictions can override these rules. Verify your employer's state tax setup.
