IRS 9100 Relief: Automatic vs. Non-Automatic Tracks and Filing

Getting IRS 9100 relief means using one of two procedures under Treasury Regulations 301.9100-1 through 301.9100-3 to make a tax election after its deadline has passed. The free automatic track lets you file the late election with a short notation and no IRS approval, as long as your election is on the eligible list and you act within 6 or 12 months. The non-automatic track requires a formal Private Letter Ruling from the IRS National Office, carries a user fee of up to $14,500, and takes months.¹ Which path applies depends on which election you missed and how much time has passed.

One boundary to know up front. Non-automatic relief is available only for regulatory elections, meaning elections created by Treasury Regulations or IRS revenue procedures. If Congress wrote the deadline directly into the Internal Revenue Code (a statutory election) and the automatic window has closed, the IRS has no authority to extend it. The opportunity is gone.¹

Which Track Applies to You

Automatic relief, under Regulation 301.9100-2, covers a defined list of elections and grants the extension without any IRS approval. You file the late election with a specific statement attached and the extension is self-executing. No user fee, no waiting.²

Non-automatic relief, under Regulation 301.9100-3, applies to regulatory elections that fall outside the automatic track. You submit a Private Letter Ruling request to the IRS National Office in Washington, D.C., pay the user fee, and wait for a discretionary decision. You carry the full burden of proving you acted reasonably and that granting the late election will not cost the government revenue.³

Check the automatic track first. It is faster, cheaper, and does not require you to argue your case.

Qualifying for Automatic Relief

Automatic relief under 301.9100-2 runs on two timelines. In both, “corrective action” generally means filing the election form on an original or amended return for the year in question. Everyone whose tax liability would be affected by the election must also file consistently with it. If a partner or shareholder filed inconsistently, the IRS can invalidate the late election.²

The 12-Month Window

A 12-month extension from the original due date is available for a specific list of regulatory elections, whether or not you filed your return on time. The eligible elections are:²

Section 444, electing a tax year other than the one otherwise required
Section 472, electing the LIFO inventory method
Section 505, late exemption application for certain employee benefit organizations
Section 508, late exemption application for a 501(c)(3) organization
Section 528, electing treatment as a homeowners association
Section 754, electing to adjust basis on partnership transfers and distributions
Section 2032A, electing to specially value qualified real property for estate tax purposes, available only if the IRS has not yet begun examining the return
Section 2701, certain gift tax elections related to qualified payment rights under the Chapter 14 valuation rules

If the election was due with your return and you obtained a filing extension, the 12 months run from the extended due date.

The 6-Month Window

All other regulatory and statutory elections that were due with a return qualify for a 6-month automatic extension, but only if you timely filed the return for the year the election should have been made and the election’s deadline was the return due date (including extensions). The 6 months run from the due date of the return excluding extensions, so the window is tight. File the return late and the 6-month automatic extension is unavailable.²

How to File

Send the election form, or an amended return with the form attached, to the same IRS service center where the return would have gone had the election been made on time. At the top of the return, statement, or election form, write: FILED PURSUANT TO § 301.9100-2. Leaving that notation off can cause the filing to be processed as an ordinary late submission rather than a 9100 relief request.²

Include every required shareholder consent, partner statement, or other ancillary document. Resolve any inconsistent filings by affected parties before you submit. There is no user fee.

Late S Corporation and Entity Classification Elections

Late S corporation elections on Form 2553, and certain late entity classification elections on Form 8832, have their own pathway under Revenue Procedure 2013-30. This is separate from 301.9100-2 and offers a longer window.⁴

Under the general rule, the entity must request relief within three years and 75 days of the intended effective date of S corporation status. The entity must have intended S corporation classification from that date, must have failed to qualify only because the election form was not filed on time, and must show reasonable cause for the delay plus diligent action once the mistake was discovered. All shareholders must provide statements confirming they reported their income consistently with S corporation status for every year since the intended effective date.⁴

If an LLC needs a late Form 8832 alongside the Form 2553 (common when the entity intended to elect both corporate status and S corporation status at once), the same three-year-and-75-day window and consistency requirements apply.

The three-year-and-75-day deadline disappears entirely for corporations meeting stricter conditions: the corporation and all shareholders reported income consistently with S corporation status from the intended effective date, at least six months have passed since the first S corporation return was filed, and neither the corporation nor any shareholder was notified by the IRS of a problem with S corporation status within six months of that filing.⁴ Meet all of those, and you can file the late Form 2553 years after the intended effective date.

Qualifying for Non-Automatic Relief

When your missed election fits neither the automatic track nor Rev. Proc. 2013-30, you need non-automatic relief under Regulation 301.9100-3. Two tests apply: you must show you acted reasonably and in good faith, and you must prove that granting relief will not prejudice the government’s interests.³

Reasonable Action and Good Faith

The IRS tends to accept situations where the taxpayer relied on a qualified tax professional who failed to make the election, or where the taxpayer did not know the election was necessary despite exercising reasonable diligence. What kills a request is evidence that the taxpayer knew about the election, understood the deadline, and chose not to file, or changed their mind after seeing how the numbers played out. The agency is looking for genuine mistakes, not do-overs.

Your request must include a detailed narrative: how the election was missed, when you discovered the error, and what you did to fix it. Speed matters. Discover the mistake in March and wait until November to file, and the IRS will want to know what took so long.

No Prejudice to the Government

The government’s interests are prejudiced if granting the late election would give you a lower total tax liability across all affected years than you would have had if you had elected on time. The IRS will not let you use hindsight to cherry-pick a tax benefit.

Prejudice is also presumed if the statute of limitations has expired for any year the election affects. To address this, you will typically agree to extend the assessment period for those years so the IRS has time to adjust your liability. Requests involving accounting method changes face a higher bar: the government’s interests are presumed prejudiced unless unusual and compelling circumstances exist.³

Filing a Non-Automatic Request

You submit a Private Letter Ruling request to the IRS National Office under the current year’s revenue procedure for letter ruling submissions. This step is document-heavy and expensive, and attempting it without an experienced tax professional is how user fees get wasted on denied requests.

What to Submit

The package needs a cover letter, a complete statement of facts, legal analysis showing you meet both standards, and affidavits from you and any tax professionals involved in the missed election. Your affidavit covers the facts of the late election, when you discovered the error, and the steps you took to pursue relief. Any tax professional involved submits a separate affidavit with their name, address, and taxpayer identification number, plus a signed declaration under penalties of perjury stating: “Under penalties of perjury, I declare that I have examined this request, including accompanying documents, and, to the best of my knowledge and belief, the request contains all the relevant facts relating to the request, and such facts are true, correct, and complete.”³ That mandatory language is non-negotiable; paraphrase it or leave it out and the request can be returned.

If any affected year is currently under IRS examination, disclose that in the request. If an examination begins while the request is pending, notify the IRS office reviewing your ruling immediately.

User Fees for 2026

The standard user fee for a 9100 relief Private Letter Ruling received after January 29, 2026, is $14,500. A separate fee of $13,900 applies to requests for an extension of time to file Form 3115 (used for accounting method changes).⁵

Reduced fees are available if you certify your gross income from your most recent timely filed federal return:

Gross income under $400,000: $3,450
Gross income from $400,000 to under $10 million: $9,775
Gross income of $10 million or more, or no certification: $14,500

Fees are non-refundable even if the IRS denies the request, which is why getting the submission right the first time matters so much.⁵

After the Ruling Is Granted

A favorable ruling letter will specify a deadline to file the actual election, and the window can be short. The timeframe varies by ruling, so read your letter carefully. One recent ruling granted just 45 days from the date of the letter to file the amended return with the election form attached.⁶

Attach a copy of the ruling letter to any tax return it affects. For electronic filing, you can attach a statement with the date and control number of the ruling instead.⁶ The ruling only extends the deadline for making the election. It does not confirm you are otherwise eligible to make it, and it does not change any other filing obligations.

If Relief Is Denied

Denial means the election is treated as never made, and your tax liability for the affected years stands as filed. For elections that would have reduced your tax or changed your entity classification, the financial impact can be severe.

A denied Private Letter Ruling request can be contested in Tax Court or another federal court, though litigation adds significant time and expense. The more practical move is to address any weakness on the “no prejudice” or “good faith” standard directly in the submission rather than hoping the IRS misses it. The agency reviews hundreds of these requests annually and knows where to look.

For taxpayers who missed a statutory election and also missed the automatic window, no remedy exists. The non-automatic path is not available for statutory elections, so the election opportunity is permanently gone.¹
