I am going to restate your questions so you can see how I am answering them.

1. You can always apply for a tax ID from the state of Missouri. Getting one sooner than later is important, because if not it may create issues later. Like if you miss your annual reports and become administratively dissolved and need to be placed in good standing again.

2. Never play with the dates. It becomes an integrity issue and will hurt your credibility. The earlier you start an organization lends to that organizations stability through longevity.

3. Deal with the IRS as soon as possible. Any delays will result in fees and interest for any outstanding taxes owed.

Let's have a 30 min consult to see what will put you straight. I am not low cost. I do bring results and will be straight with you on cost and possibly show you a way to fund the assistance needed.
