Travel Nurse Salary Illinois 2026 Chicago Non-Compact Premium, Cook County Trauma & COL Offset

Illinois travel nurses earn a statewide mean of $97,999/year — but the story is really about Chicago. Cook County Level I systems pay $2,900–$3,500/week, the non-compact license adds a 6–10 week lead time, and the 4.95% flat income tax is real but rarely the deciding factor. Here's the full picture for 2026 assignments.

Chicago vs. Downstate: The Pay Gap Is Real

Illinois pay splits sharply at the Cook County line. Chicago metro — anchored by Northwestern Memorial, Rush University Medical Center, University of Chicago Medicine, and Loyola University — consistently posts the highest travel rates. Downstate markets (Peoria, Rockford, Springfield) pay competitively but lag 15–25% behind metro rates. The INA (Illinois Nurses Association) has collective bargaining agreements at several major Chicago systems, which sets a floor that travel rates must clear.

Non-Compact License: Plan 6–10 Weeks Ahead

IDFPR (Illinois Department of Financial and Professional Regulation) handles RN endorsements. The fee is $50, and standard processing runs 6–10 weeks. Expedite is available for a higher fee but not always honored within the stated timeframe. Most agencies will not submit your profile to a Chicago system until IDFPR approval is in hand — which means your assignment start date shifts to match.

Practical steps: Apply immediately after accepting an offer or when seriously considering Illinois assignments. Track your application in IDFPR's online portal. Bring your current license verification and official transcripts if IDFPR requests them (international-educated nurses should expect additional documentation). The 6–10 week window is the single most common reason travel nurses miss Chicago contract start dates.

Cook County Trauma: Level I Rates at Northwestern & Rush

Northwestern Memorial Hospital and Rush University Medical Center operate as two of the busiest Level I trauma centers in the Midwest. Travel ICU and ER nurses there are among the highest-paid in the state. Standard 13-week contract rates for ICU travel nurses run $3,100–$3,600/week all-in; during peak shortage periods — which Chicago has seen every winter since 2022 — crisis rates have reached $3,400–$4,000/week.

University of Chicago Medicine (Comer Children's, too) and Loyola University Medical Center in Maywood carry similar rates. Advocate Health facilities across the collar counties post slightly lower but still metro-level compensation. The INA's union contracts at several of these systems establish shift-differential and overtime floors that travel agencies reference when setting package rates. For a travel nurse with 2+ years ICU or ER experience, Chicago competes directly with California and New York for top-of-market weekly pay.

Illinois 4.95% Flat Tax: How Much Does It Actually Cost?

Illinois levies a 4.95% flat income tax on all wages, with no brackets. For travel nurses, only the taxable (base hourly × hours worked) portion of your package is subject to Illinois income tax; housing and M&IE stipends are non-taxable as long as you maintain a tax home.

The math is clear: Chicago's metro premium over comparable Midwestern assignments (Peoria, St. Louis, Indianapolis) typically exceeds the state income tax cost by 5–10x on any given contract. The 4.95% rate is worth knowing and worth tracking for your year-end filing, but it rarely changes the go/no-go decision on a Chicago assignment.

Cost of Living Offset: Housing in Chicago on a Travel Package

Chicago is the most expensive Illinois assignment market. GSA FY2027 sets the Cook County lodging rate at $191/night during standard months (with seasonal variation). Most travel nurses on Chicago contracts find furnished housing at $1,600–$2,100/month — which, with a weekly housing stipend of $700–$950/week ($455–$570/30-day equivalent from the weekly rate), puts most nurses cash-flow positive on housing by $150–$400/month.

Neighborhoods worth targeting: Rogers Park, Andersonville, Avondale, and Logan Square have furnished short-term rentals priced well below Lincoln Park or the Gold Coast. Most major Cook County hospital campuses (Northwestern, Rush, Loyola-Maywood) are accessible via CTA Blue or Red Line, so car-free is viable. Suburbs like Oak Park, Skokie, and Evanston offer lower furnished-rental rates and good transit access. Avoid locking into a 30-day lease sight-unseen; negotiate the 13-week rate upfront.
