Common mistakes that delay your Tax ID in Chicago

These are the issues that send applications back for correction in Chicago most often. Avoid them up front and you'll typically clear the queue in the Immediate online window.

Submitting an incomplete application. Roughly half of Chicago Tax ID delays trace back to missing signatures, the wrong form revision, or fees paid to the wrong department. Run through the Chicago clerk's checklist twice before you submit.
Underestimating Chicago's queue. Major metros like Chicago routinely run past the published Immediate online window because volume spikes seasonally. File at least 30 days before you intend to operate — and don't sign a commercial lease that starts before your projected approval date.
Mismatched entity name. The legal name on the EIN Registration application must match the entity's filing with Illinois Secretary of State exactly — punctuation included. A DBA suffix or comma in the wrong place sends it back to "needs correction."
Not budgeting for renewal. The first EIN Registration fee is only part of the cost — renewals (one-time) cost roughly 60–70% of the initial fee, and missing the renewal window in Chicago typically means re-applying from scratch.
