If you are planning on incorporating or setting up your LLC in Illinois, then this could save you money!
Illinois tries to charge an extra $100 expedited fee, that’s 66% more than the original $150 filing fee!

Their standard services could take ten business days. They say that for a $100 extra expedited fee, they will approve it in 1 day. It’s been our experience, that the regular service, without expediting only took a few days. In a lot of cases, it was approved in the same one-day turnaround that’s guaranteed by spending the extra $100.
So unless you absolutely need it the next day, save your $100 for a better value somewhere else.
