Accounting & Tax Services in Rockford, IL
Rockford anchors Northern Illinois’s manufacturing corridor, where Collins Aerospace’s 3,000-employee campus and a dense network of precision machining, tool and die, and fastener manufacturers form the backbone of the regional economy. The city’s aerospace heritage traces back decades, and today Rockford suppliers serve both commercial aviation and defense programs, creating complex cost accounting and contract compliance requirements that demand specialized CPA expertise.
The Chicago Rockford International Airport has emerged as a major cargo hub, with Amazon Air and UPS operations driving logistics growth that complements the manufacturing base. Mercyhealth and OSF HealthCare anchor the healthcare sector with combined employment exceeding 8,000 positions. At roughly 40% lower business costs than Chicago, Rockford offers manufacturers and professional services firms a cost-competitive alternative while maintaining access to Midwest supply chains and the I-90 corridor to Chicago.
SDO CPA works with Rockford business owners in aerospace, precision manufacturing, and healthcare to structure entities, claim R&D credits for process improvements and tooling development, and manage Illinois’s flat-rate tax obligations. Whether you’re a Collins Aerospace Tier 2 supplier along the I-90 corridor or a healthcare practice affiliated with Mercyhealth, we provide monthly bookkeeping and fractional CFO services scaled to your growth stage.
Illinois Tax Planning Tip
Illinois has a flat 4.95% income tax that applies to all pass-through entity income. Rockford manufacturers should evaluate Illinois’s pass-through entity tax (PTE) election to bypass the federal SALT deduction cap, potentially saving $5,000-$15,000 for owners with $200K+ in Illinois-source income. Aerospace suppliers should also track R&D tax credits for qualifying activities like process improvements and tooling development.
