Most boards find the revocation late. The letter went to a treasurer who left, or the organization only learns of it when a grantmaker runs a status check, and by then the 15-month window for the easy route has been shut for a year or more.
Two routes are still open at that point, and they answer two different questions. One asks the IRS to treat the organization as never having lost exemption. The other accepts the gap and starts again from the day the application is postmarked. The choice between them is the whole decision, and it is worth making deliberately rather than by default.
Route one: retroactive reinstatement after 15 months
The IRS keeps retroactive reinstatement available with no outer deadline. What changes past 15 months is the burden. Inside the window, an organization that cannot use the streamlined route has to establish reasonable cause for its failure to file at least one of the three years. Past the window, the statement must establish reasonable cause for all three consecutive years.
That is not a formality. It means three separate accounts of what happened in three separate years — who was responsible, what the organization believed about its filing obligation, when it discovered otherwise, and what has been put in place since. A board that changed hands twice in that period is reconstructing history it did not witness, and that is the actual work of this route.
Alongside the statement, the same two mechanical requirements apply as inside the window:
- properly completed and executed paper annual returns for the three consecutive years that caused the revocation; and
- an application on Form 1023, Form 1024 or Form 1024-A with the appropriate user fee.
Notice what is missing from that list. Form 1023-EZ — the short application, and the cheaper $275 fee — is listed by the IRS for the streamlined route and for post-mark date reinstatement, and is not listed for either retroactive route. An organization small enough to have qualified for the EZ on size still files the full Form 1023 at $600 if it wants the revoked years back this way. That single line is where most of the cost difference between the two paths actually comes from.
In exchange, the IRS states it will not impose the Section 6652(c) penalty for failure to file the returns submitted with the application — which for three years of late returns is not a small exchange.
Route two: post-mark date reinstatement
The other option asks for nothing about the past. The organization submits Form 1023, 1023-EZ, 1024 or 1024-A with the user fee, no reasonable-cause statement is required, and exemption is reinstated effective from the post-mark date of the application.
It is the cheaper and faster paperwork, and for many organizations it is the right answer. It is also the route that leaves the gap in place: the period between revocation and that postmark is simply not covered by exempt status, and nothing later closes it.
Whether that matters is a question about your own history, not about the IRS. Organizations that raised little or nothing during the gap, took no grants conditioned on exempt status, and want to be running again as fast as possible are the natural fit. Organizations that accepted donations, held a grant, or filed something with a state that assumed exemption during those years have a reason to want the record made continuous.
Deciding between them
Three questions settle it in practice. What happened financially during the gap. Whether the three years of missed filings have an account behind them that someone can actually write — an illness, a treasurer's departure, a genuine belief the organization was below the filing threshold — or whether the honest answer is that nobody was watching. And whether the difference between the $275 and $600 user fees, plus the work of three reasonable-cause narratives, is worth the years being restored.
Before any of that, check the date. The window runs from the later of the CP-120A letter or the Auto-Revocation List posting, and organizations that count from the letter alone routinely believe they are outside a window they are still inside. It is worth ten seconds of checking before accepting the harder route.
What GoodStanding prepares on this route
The Full Reinstatement Pack, $699 one-time, is built for exactly this case: the full Form 1023, the three years of paper annual returns, and the reasonable-cause narrative written to cover all three years rather than one. The $349 Streamlined Cure Pack is for organizations still inside the window and eligible for the streamlined route — the free diagnostic on the home page pulls the public record and says which of those you are, with no account and nothing bought.
GoodStanding prepares; the organization signs and files. We are not a law or CPA firm and do not represent anyone before the IRS. If your case is likely to be argued rather than filed, the guide to the four routes back sets out who does that and what it costs. Contact us reaches a person.
