How the S Corp 5-Year Waiting Period Works After Revocation

A corporation that loses its S election generally has to wait five taxable years before making a new one, and that is the core of the S corp 5-year waiting period under Internal Revenue Code Section 1362(g).¹ The clock runs from the first taxable year the termination was in effect, and it applies whether the S status ended by shareholder revocation or because the corporation stopped qualifying. Two escape routes exist: the IRS can grant early re-election in specific circumstances, and if the termination was accidental, a separate relief provision can treat the S status as if it never lapsed.

How to Count the Five Years

The statute requires waiting until the “5th taxable year which begins after the 1st taxable year for which such termination is effective.”¹ For a calendar-year corporation whose S status ended effective January 1, 2024, the earliest new election year is 2029. File Form 2553 before that window opens and the IRS rejects it.²

The rule does not care whether the termination was your choice. Voluntary revocations and involuntary terminations both trigger the same five-year block.

When the Clock Starts

Pinpointing the start date matters because it fixes the earliest year you can re-elect. It depends on how the S status ended.

Voluntary Revocation

If shareholders holding more than half the stock consent to a revocation filed on or before the 15th day of the third month of the tax year (March 15 for calendar-year filers), it takes effect on the first day of that same year. Filed after that, it takes effect on the first day of the next tax year, unless the revocation specifies a later effective date.³

Involuntary Termination From Losing Eligibility

If the corporation stops qualifying as a small business corporation — for example, by issuing a second class of stock or admitting an ineligible shareholder — termination takes effect on the date of the disqualifying event.¹ The tax year splits into an S short year ending the day before the event and a C short year starting on the event date. The five-year clock starts with that C short year.

Passive Investment Income Termination

An S corporation with accumulated earnings and profits from prior C years loses S status automatically if more than 25 percent of its gross receipts come from passive investment income for three consecutive years.¹ Termination takes effect on the first day of the tax year following the three-year period, and that year begins the countdown. Corporations without accumulated C-era earnings are not exposed to this rule regardless of how passive their income is.

Creating a New Entity Does Not Reset the Clock

Treasury Regulation 1.1362-5 treats a new corporation as a “successor” that inherits the waiting period when two conditions overlap: the same people who owned 50 percent or more of the terminated corporation on the termination date own 50 percent or more of the new corporation, and the new corporation either acquired a substantial portion of the old corporation’s assets or received a substantial portion of its own assets from the old corporation.⁴ Both prongs must be satisfied. Changing owners or starting with entirely new assets can break the chain, but the IRS looks at these structures carefully.

The One Situation Where No Wait Applies

A corporation can re-elect S status immediately, without IRS permission, only if the original termination happened on the very first day the election was supposed to take effect — either because the corporation revoked effective that day, or because it failed to meet the small business corporation definition that day.⁴ This covers filing Form 2553 and reversing course before any period as an S corporation actually ran. It does not help a corporation that operated as an S corp for any length of time before losing the election.

Inadvertent Termination Relief: The Better Path When It Fits

Before treating the five-year wait as inevitable, check whether the termination might qualify as inadvertent. Section 1362(f) lets the IRS treat the corporation as though the termination never happened, meaning continuous S status with no re-election required.¹

Three things must be shown: the termination was inadvertent, the corporation corrected it within a reasonable time after discovery, and the corporation and every affected shareholder agree to any adjustments the IRS requires.¹ The regulations describe “inadvertent” as an event not within the corporation’s reasonable control, not part of a plan to end the election, and occurring without the corporation’s knowledge despite its efforts to prevent it.⁵

Typical fact patterns include a minority shareholder transferring stock to an ineligible owner without the corporation’s knowledge, or a trust silently falling out of qualified status. The corporation carries the burden of proof and submits a ruling request laying out the original election date, what caused the termination, when and how it was discovered, and what was done to fix it.⁵ Voluntary revocations do not qualify; Section 1362(f) covers only terminations under paragraphs (d)(2) and (d)(3), not revocations under (d)(1).

Simplified Relief Under Revenue Procedure 2022-19

Some validity problems can be fixed without a Private Letter Ruling. Revenue Procedure 2022-19 provides streamlined procedures for issues such as disproportionate distributions that did not actually create a second class of stock, missing shareholder consents on Form 2553, missing officer signatures, and governing provisions that fail to confer identical distribution and liquidation rights. If the S election was invalid or terminated solely because of non-identical governing provisions, retroactive corrective relief is available when the corporation filed Form 1120-S consistently for every affected year and completes the required corrective statements.⁶ The streamlined route saves substantial time and money compared with a full ruling request.

Asking the IRS for Early Re-Election

When neither the first-day exception nor inadvertent-termination relief fits, a corporation still inside the five-year window can ask the IRS to consent to an early re-election through a Private Letter Ruling submitted to the national office.

The regulation flags two fact patterns that tend to work. The strongest is a change of more than 50 percent of the corporation’s ownership to people who held no stock on the termination date; in effect, the current owners had nothing to do with losing the election.⁴ Document these transfers with stock ledgers, purchase agreements, and similar evidence.

Without a majority ownership change, consent is “ordinarily denied” unless the corporation can show the event was not reasonably within its control and was not part of a plan to end the election.⁴ A detailed timeline, financial records, and correspondence with third parties help.

Timing and Fees

The ruling request must include a full written statement of the facts, references to the applicable regulations, and a declaration under penalty of perjury. The IRS aims to respond to letter ruling requests within 180 days of receipt, though complex cases run longer.⁷

User fees for 2026 (effective for requests received on or after December 29, 2025) scale with the applicant’s gross income:⁸

Gross income under $400,000: $3,450
Gross income of $400,000 to under $10 million: $9,775
All other letter ruling requests: $43,700

Fees are published annually in the first Internal Revenue Bulletin of the year and are nonrefundable regardless of outcome.

Filing Form 2553 When the Wait Is Over

Once the five-year period runs out — or the IRS grants early consent — the corporation files Form 2553 to make a fresh S election. The filing deadline is no more than two months and 15 days after the beginning of the tax year for which the election takes effect, or any time during the preceding tax year. Every shareholder on the date the election is made must sign. For a late filing, every shareholder or former shareholder who held stock between the intended effective date and the filing date must also consent.⁹ Community property spouses, trusts, estates, and minors each carry their own consent rules; a single missing signature can invalidate the election and, in the worst case, start a new termination cycle.
