Auroran LLC FAQ
Do I have to form my LLC at the Aurora city level?
No. LLCs are formed at the state level with the Illinois Secretary of State, not at the city level. Aurora may require a separate business license to operate, but the LLC itself is a state filing.
Does Aurora have a city-specific business license?
Most Aurora businesses need a business license issued by the city or county. The exact requirements depend on industry and business activity. Contact the Aurora city clerk or use our business license lookup tool.
How much does it cost to form an LLC in Aurora?
The Illinois state filing fee plus any Aurora business license fee. File.Business charges $0 service fee on top. See our Illinois LLC cost breakdown.
Can I form a Auroran LLC remotely?
Yes. Illinois accepts online filings. You do not need to be physically present in Aurora or Illinois. File.Business handles the entire process remotely.
Should I form in Illinois or in another state like Delaware?
If you operate primarily in Aurora, you should form in Illinois. Forming out of state (in Delaware, for example) requires foreign qualification back in Illinois, doubling fees. Delaware is best for venture-backed startups or businesses with no specific home state.
