Illinois · Cities We Serve
An Illinois bookkeeper for your city — where the city can change the tax picture, not just the economy.
Unlike no-income-tax states, Illinois has a flat 4.95% income tax and the PPRT, and Chicago levies its own taxes on top — a 10.25% combined sales tax and a 15% lease/“cloud” tax. So in Illinois the city can change the actual tax stack, not only the industry mix: Chicago's finance, fintech and SaaS, Aurora's manufacturing and data centers, Naperville's professional services, Joliet's intermodal logistics, Rockford's aerospace machining, Springfield's state government. We have a dedicated bookkeeper for the major metros and serve all 102 counties remotely, by a named Certified ProAdvisor. We deliver the books; your CPA files.

Illinois bookkeeping, city by city.
TechBrot provides Certified QuickBooks ProAdvisor bookkeeping across Illinois — with dedicated, genuinely localized pages for the state’s major metros and remote service in all 102 counties. Unlike no-income-tax states, Illinois has a flat 4.95% income tax and the statewide PPRT (2.5% for C-corps, 1.5% for pass-throughs, for a 9.5% combined C-corp rate), and a city can layer its own taxes on top — so in Illinois the city can change the actual tax picture, not only the economy. Chicago runs on finance, fintech and SaaS and adds its own 10.25% combined sales tax and a 15% lease/“cloud” tax; Aurora on manufacturing and data centers; Naperville on professional services; Joliet on intermodal logistics; Rockford on aerospace machining; Springfield on state government and agriculture; Peoria on heavy-equipment manufacturing and healthcare; Champaign on the University of Illinois and a research/tech cluster; Bloomington on insurance and EV manufacturing; Decatur on agribusiness processing; and Schaumburg on suburban corporate offices and Woodfield retail. We build the right industry accounting and the Illinois stack (the flat 4.95% income tax, the PPRT, the 6.25%→10.25% sales tax via IDOR’s ST-1, and Chicago’s lease/cloud tax where it applies) into your books, by a named bookkeeper on the same file every month. Independent firm — not affiliated with Intuit Inc.; we deliver the books, your CPA files.
