Should I form my Auto Repair LLC in Illinois or a different state?

For most auto repair operating in Illinois, forming locally avoids foreign qualification costs and simplifies compliance. Delaware, Wyoming, or Nevada formation only makes sense if you genuinely operate there. Running a Illinois-based business as a Wyoming LLC typically costs more (both Wyoming fees + Illinois foreign qualification) while providing no real tax benefit.

By default, a single-member LLC is taxed as a disregarded entity (Schedule C); multi-member as a partnership. Once net profit exceeds ~$80K, an S-Corp election typically saves significantly on self-employment tax. Note that Illinois's franchise tax (1.5% replacement tax on net income (for S-corps)) applies regardless of federal classification.
