Should I hire an LLC filing service in Illinois?

Hiring an LLC filing service isn’t going to get your LLC approved any faster. Filing companies still have to wait for the state to approve your LLC.

However, the benefit of hiring a filing company isn’t to reduce LLC approval time. It’s to have someone else take care of the paperwork for you (and make sure it’s filed correctly).

If you want to hire someone to form your LLC, we recommend Northwest Registered Agent ($39 + state fees).

Northwest Registered Agent has been in business for over 20 years and they have the best customer support.

Our favorite thing about Northwest is that you can use their address throughout your LLC filing. This can provide you with additional privacy by keeping your address off public records. No other filing company offers this.

How long does it take to get an LLC in every state?

Important: Just because one state is faster than another doesn’t mean you should form your LLC there. If you form your LLC out-of-state, you’ll need to register it as a foreign LLC in your home state. For more information, please see the best state to form an LLC.
