When choosing an accountant or bookkeeper for your Naperville small business, you should consider the following factors:
Certifications and Illinois Compliance: Verify the accountant or bookkeeper holds proper credentials, particularly if they work as a CPA. They should demonstrate thorough knowledge of Illinois tax regulations, including specific DuPage County requirements that affect Naperville businesses differently than neighboring Cook County operations.
Technology Industry Experience: Given Naperville's growing technology sector, seek financial professionals familiar with tech startups and established firms. An accountant who understands software development tax credits, R&D deductions, and intellectual property valuation will provide more value than generalists, especially with Naperville's tech corridor continuing to expand along the I-88 innovation corridor.
Understanding of Local Economic Dynamics: Find professionals who grasp Naperville's unique position as both a wealthy Chicago suburb and an independent economic center. Your accountant should recognize how proximity to major corporate headquarters, excellent schools, and high household incomes create distinct financial opportunities and challenges for local businesses.
Knowledge of Illinois Tax Incentives: Illinois offers specific tax advantages for businesses, including the Economic Development for a Growing Economy (EDGE) Tax Credit and the High Impact Business program. A Naperville-savvy accountant can help navigate these opportunities while addressing DuPage County's property tax structure, which differs significantly from neighboring counties and impacts business location decisions.
