A Registered Nurse earning $100K/year in Idaho takes home $73,825 after all taxes. That’s $6,152/month, with an effective tax rate of 26.2%.
The estimated median salary for Registered Nurses in Idaho is $78K (adjusted from the national median of $82K using Idaho’s cost-of-living index of 95). At $100K, you’re earning 28% above the state-adjusted median for this profession.
You’re earning above the median, suggesting you’ve moved beyond entry-level. As your career progresses, each raise will be taxed at your marginal rate, so understanding your bracket position helps you evaluate the true value of promotions and raises.
Filing as married filing jointly on $100K (single earner) saves you $5,585/year ($465/month) compared to filing single. This marriage bonus comes from the doubled standard deduction ($32,200 vs $16,100) and wider lower brackets.
Registered nurses who work overtime, holiday shifts, or pick up extra shifts often see those hours taxed at their marginal rate, which can feel punitive. Travel nurses face additional complexity: per diem stipends for housing and meals are tax-free only if you maintain a "tax home" (a permanent residence you pay for). If you give up your permanent home, those stipends become taxable. Night and weekend differentials are always taxable as ordinary income. Union dues may be deductible in some states even though they’re not federally deductible.
At #41 out of 50 states for take-home pay on a $100K salary, Idaho is one of the highest-tax states at this salary level. You’d keep $5,300 more per year in Alaska (#1), or $442/month.
After adjusting for cost of living, Idaho ranks #30 in purchasing power. That’s a boost from #41 in raw take-home — Idaho’s lower costs stretch your paycheck further.
