How to register your Illinois LLC in Kentucky

Check name availability in Kentucky

Before filing, verify that your LLC name (or a distinguishable variation) is available in Kentucky. If your exact name is already taken, you may need to register under a fictitious or assumed name.

Search the business name register on the Kentucky Secretary of State website before you file.

No home-state certificate needed

Kentucky requires no home-state certificate when a foreign LLC registers here. The form carries a self-certification instead.

Important to know about Kentucky

The $175 Limited Liability Entity Tax is owed to the Department of Revenue and is separate from the $15 annual report, with a different deadline and a different agency. A single-member LLC owned by an individual files Form 725 and owes it in its own right.
