Registered Nurse Salary in Missouri (2026)

Most MO RN roles are FLSA non-exempt (hourly W-2) — the standard structure in hospital + ambulatory nursing. Per-diem / float pool / travel roles can be W-2 hourly at $42-78/hr (HCA Midwest travel agency at $85-145/hr for 13-week assignments). OBBBA's OT premium deduction (2025-2028) applies to W-2 hourly RN whose hours exceed 40/week. Practical reality: most MO RNs work 36-hour weeks (3 × 12s) with 1-2 OT shifts/month + holiday + shift differential = 200-400 OT hrs/year typical for staff RN.

The 2025 OBBBA law created a federal-only deduction on the premium portion of overtime pay for tax years 2025-2028 — up to $12,500 single / $25,000 MFJ. Premium portion equals the half of time-and-a-half. For a BJC staff RN with 300 OT hrs/year × $36/hr regular rate = $16,200 total OT compensation, the premium half roughly $5,400 — fully qualifies for OBBBA federal deduction. Federal savings 22% bracket × $5,400 = $1,188/year federal back.

Missouri has not formally conformed to OBBBA. The OT premium stays fully Missouri-taxable at the 4.7% top rate: $16,200 OT × 4.7% = about $760 of Missouri tax, plus $162 of St. Louis earnings tax, because BJC's Barnes-Jewish campus is inside the city — owed whether the RN lives in the city or the county. Both are owed with or without OBBBA, so they do not reduce its benefit: $1,188 federal, less about $8 because Missouri's deduction for federal tax shrinks with the federal bill. A county hospital job plus a county home avoids the city tax.

Real numbers for a BJC staff RN at $80K base + $16K OT (300 hrs × varying rates) + $4K shift differential = $100K total. Missouri state tax for a single filer = about $3,670/year (3.7% of pay), plus $1,000 of St. Louis earnings tax on BJC wages wherever the RN lives — about $4,670 combined. Same comp in MD: about $6,490 at the 2.25% county floor, $7,380 in a 3.20% county. Compared to TN (0%): TN saves about $3,670/year MO state (plus the city tax at a city hospital). The MO advantage vs blue-state RN markets is substantial even with the city tax.

Travel nursing arbitrage is a unique MO active-duty lever. NLC compact full participation since 2023 enables MO-resident nurses to take 13-week assignments at HCA Midwest, BJC-affiliated, or any compact-state facility at $85-145/hr while maintaining MO residency. Tax treatment: travel-source W-2 income is sourced to the assignment state's tax rules; for assignments in 0%-state (FL, TX, NV, WA, AK), the full income remains 0% state. For higher-tax states (CA, NY, NJ), the travel-source income is taxed by that state but MO residency itself doesn't add MO state tax beyond home-state-source income. Annual income $95-155K typical for full-year travel nurses based in MO.

BJC academic-medical premium drives the MO nursing top tier. BJC staff RN comp ($72-95K depending on specialty) runs $5-15K above community-hospital comp at HCA Midwest or regional hospitals. Plus BJC's 403(b) (501(c)(3) academic medical center) offering 403(b) + match — the deferral cuts federal AND Missouri tax (Missouri starts from federal AGI), a major active-duty lever. Goldfarb School of Nursing (BJC-affiliated) provides BSN + MSN pipeline directly into BJC clinical roles.

MO nursing clusters in three corridors. The St. Louis corridor (BJC HealthCare + Washington University + Barnes-Jewish + St. Louis Children's, SSM Health, Mercy Health, plus regional Truman Medical Centers, Mercy South Hospital, Christian Hospital) is the densest US academic-medical nursing market in the Midwest by single-employer concentration. The Kansas City corridor (Saint Luke's Health System, Children's Mercy KC, HCA Midwest Health, plus University of Kansas Health System on KS side draws MO RNs, plus Truman Medical Centers KC) anchors the western MO + KS metro nursing market. The Springfield / Columbia corridors (CoxHealth + Mercy Springfield, MU Health Care Columbia) anchor southwest + central MO at materially lower COL.

Housing on a staff RN base + OT income tier ($85-110K total): St. Louis County affordable (Affton, Maplewood, Brentwood, Florissant, Hazelwood) $250-475K · St. Louis County mid-tier (Kirkwood, Webster Groves, Ballwin, Chesterfield) $400-700K · Kansas City suburbs (Lee's Summit, Liberty MO, Independence, Blue Springs) $325-525K · Overland Park / Leawood KS $400-650K (KS resident, MO commuter) · Columbia (Boone) $275-525K · Springfield (Greene) $250-475K. Travel nurse + BJC specialty RN comp ($105-155K) can stretch into St. Louis County premium tier ($550K+) with spouse income.

Most MO nurses retire in-state — MO's 0% estate + 0% inheritance (since 2005) + a 4.7% top rate with Social Security fully exempt since 2024 and partial pension exemptions + low 0.97% property tax + low overall COL makes MO one of the more favorable Midwest RN retirement structures. Common retirement patterns: stay in St. Louis County / KC suburbs, or migrate to Lake of the Ozarks (Camden / Miller Counties) for waterfront retirement, or Branson area (Taney County) for tourism + lower COL. Some senior MO nurses relocate to FL / NC / TN for warmer climate, but MO's structure doesn't push relocation the way MA / MD / NY do.

Years 0-3 (post-RN): $58-72K. ADN or BSN + NCLEX-RN + MO Board of Nursing licensure (or NLC compact transfer from another state). BSN preferred at most MO academic centers. Goldfarb School of Nursing at Barnes-Jewish College, MU Sinclair School of Nursing, Saint Louis University, UMKC School of Nursing, Missouri State, Missouri Western feed in-state pipeline. Decision point: academic-medical (BJC + WashU $72K starting + Magnet premium) vs HCA Midwest regional ($62-72K) vs SSM / Mercy ($65-75K) vs critical-access rural ($55-68K) vs travel pathway after 2-3 years bedside experience.

Years 3-10 (specialty / charge nurse / travel): $72-128K depending on specialty + travel decision. Specialty RN (ICU, ER, OR, PACU, Cath Lab) with cert (CCRN, CEN, CNOR) reaches $78-108K + shift differential. Travel nursing through HCA Midwest or independent agencies reaches $95-155K full-year at $85-145/hr × 36-48 weeks. Charge nurse / clinical coordinator at BJC / SSM / Mercy / Saint Luke's reaches $88-115K. Maxing 403(b) at BJC ($24,500/year) is the peak active-duty lever for academic-track RN.

Years 10+ (senior / leadership / advanced practice): $105-155K depending on track. Nurse Manager / Director $105-145K. Pursue MSN → NP / CRNA / clinical specialist for advanced practice (see nurse-practitioner-missouri for NP comp). Senior travel nurses with stacked specialty certs reach $135-175K with consistent travel. Most MO RNs retire in-state — MO's 0% estate + 0% inheritance + a 4.7% top rate with Social Security exempt is favorable.
