Common mistakes that delay your S-Corp Filing in Ontario

These are the issues that send applications back for correction in Ontario most often. Avoid them up front and you'll typically clear the queue in the 30-90 days (IRS acceptance letter) window.

Submitting an incomplete application. Roughly half of Ontario S-Corp Filing delays trace back to missing signatures, the wrong form revision, or fees paid to the wrong department. Run through the Ontario clerk's checklist twice before you submit.
Filing without confirming zoning first. Even in mid-sized cities like Ontario, applications get rejected because the proposed location isn't zoned for the use described in the application. Pull a zoning confirmation letter from Ontario's planning desk before the licensing application goes in.
Mismatched entity name. The legal name on the S-Corporation Election application must match the entity's filing with California 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 S-Corporation Election fee is only part of the cost — renewals (once (continues until revoked)) cost roughly 60–70% of the initial fee, and missing the renewal window in Ontario typically means re-applying from scratch.
