You do not find out you picked the wrong form until it is too late.
The IRS does not warn you at the start. You fill in the short form because someone said it was easier, you pay the fee, and then you wait. Somewhere between six weeks and six months later a letter arrives saying you were never eligible in the first place.
Most “am I eligible” checklists online cover a handful. The IRS worksheet has thirty-four, and every one of them can disqualify you on its own.
A single yes anywhere on the worksheet takes the short form off the table. Not a warning, not a smaller form, but the full thirty-page Form 1023 instead.
