Chicago drives the state's economy through finance, commodities trading, healthcare systems, and Fortune 500 headquarters. The city commands high housing costs, but downstate regions like Springfield and Champaign deliver classic Midwest affordability. Property taxes create the real burden - often reaching $8,000-12,000 annually even for modest suburban homes.

Living and Working in Illinois

Economic Overview

Job Market

Chicago anchors Illinois employment through diverse sectors. Finance and trading remain strong - the Chicago Board of Trade and CME Group provide high-compensation careers. Healthcare systems hire extensively throughout Chicagoland. Manufacturing maintains significant presence despite decades of decline. Transportation and logistics benefit from central US location. State government and higher education dominate downstate employment. Technology companies increasingly choose Chicago for operations. An $85,000 position in Chicago delivers lifestyle comparable to perhaps $70,000 in downstate Illinois after accounting for dramatically higher Chicago housing and property taxes, despite identical state income tax rates.

Cost of Living

Illinois costs split dramatically between Chicago and downstate. Chicago proper commands high prices - rent for decent apartments often runs $1,500-2,500, with home prices in desirable neighborhoods exceeding $400,000. Suburbs provide more moderate housing but property taxes can reach $8,000-12,000 annually even for modest homes. Downstate cities like Springfield, Champaign, and Rockford offer genuine Midwest affordability with housing costs 40-60% below Chicago levels. Sales tax reaches 10.25% in Chicago, among the nation's highest. Utilities cost more during brutal winters. The cost division means identical salaries deliver vastly different lifestyles depending on location within Illinois.

Frequently Asked Questions

How accurate is this calculator?

Our calculator is very accurate for most people. We use the current federal and Illinois state tax rates. However, everyone's situation is unique - things like additional withholdings, pre-tax deductions (401k, health insurance), or local taxes can affect your actual paycheck. Think of this as a solid estimate rather than an exact figure.

Why is my actual paycheck different?

A few reasons. Your employer might withhold extra for benefits, retirement contributions, or you might have requested additional withholding. Some Illinois localities also have their own taxes. Check your pay stub for the full breakdown.

Should I adjust my withholding?

That depends. If you're getting a huge refund every year, you're basically giving the government an interest-free loan. If you owe a lot at tax time, you might want to withhold more. The sweet spot is owing or getting back a small amount. Use this calculator to see if your current withholding makes sense.
