Common mistakes that delay your Sole Prop Filing in Ann Arbor

These are the issues that send applications back for correction in Ann Arbor most often. Avoid them up front and you'll typically clear the queue in the Same day to 2 weeks window.

Submitting an incomplete application. Roughly half of Ann Arbor Sole Prop Filing delays trace back to missing signatures, the wrong form revision, or fees paid to the wrong department. Run through the Ann Arbor clerk's checklist twice before you submit.
Filing without confirming zoning first. Even in mid-sized cities like Ann Arbor, applications get rejected because the proposed location isn't zoned for the use described in the application. Pull a zoning confirmation letter from Ann Arbor's planning desk before the licensing application goes in.
Mismatched entity name. The legal name on the Sole Proprietorship Registration application must match the entity's filing with Michigan LARA exactly — punctuation included. A DBA suffix or comma in the wrong place sends it back to "needs correction."
Not budgeting for renewal. The first Sole Proprietorship Registration fee is only part of the cost — renewals (annual (varies by locality)) cost roughly 60–70% of the initial fee, and missing the renewal window in Ann Arbor typically means re-applying from scratch.
