S-Corp Termination + Revocation: How to Unwind

#Why most S-corps never terminate

For most owner-operator S-corps, the election is one-and-done. You file it once, at formation or shortly after. It runs for the life of the business. It expires only when the business is sold or dissolved.

Termination is a tail-end event. We see it in three scenarios at ETS:

Scenario 1: Sale of the business. The buyer wants to buy assets, not stock, to dodge successor liability. Or the buyer is a C-corp buying the target via a §338(h)(10) election. Or the seller wants to cash in built-in gains under specific structures. The election unwinds as part of the deal.

Scenario 2: Capital raise that needs a C-corp structure. Outside investors want preferred stock, convertible notes, or other equity tools that S-corp single-class-of-stock rules do not allow. The election gets revoked. The entity converts to a C-corp. The capital raise proceeds.

Scenario 3: The business has fundamentally changed. What was a service business now has real passive income, say real estate rentals or an investment portfolio. The S-corp election becomes awkward to run. Or it runs afoul of the §1362(d)(3) passive income limit. The owner revokes to simplify.

In all three cases, the termination is a planned event. There are real business reasons behind it. The casual “I changed my mind, let me unrevoke” termination is almost never the right call. The 5-year wait under §1362(g) is real. Most owners who revoke casually regret it.

#The three termination paths at a glance

#Path 1: Voluntary revocation under §1362(d)(1)

The cleanest exit. Shareholders holding more than 50% of the stock vote to revoke the election. You file a Statement of Revocation with the IRS service center where the corporation files its tax returns.

#What goes into the Statement of Revocation

The statement is a written document signed by the consenting shareholders. It contains:

1. Corporation name, EIN, and address
2. Statement that the corporation is revoking the S election under §1362(a)
3. Effective date of the revocation (see “effective date rules” below)
4. Number of shares outstanding on the revocation date
5. Number of shares held by consenting shareholders
6. Signature and consent of shareholders holding more than 50% of the outstanding stock
7. Date of the consent

No specific IRS form exists for the Statement of Revocation. It’s a narrative document drafted by the corporation or its counsel.

#Effective date rules

§1362(d)(1)(C) governs the effective date:

• Filed by the 15th day of the 3rd month of the tax year: The revocation takes effect the first day of that tax year. For calendar-year corps, that is retroactive to January 1. For a calendar-year corp, filing by March 15 means the revocation takes effect January 1 of that same year. The entire year becomes a C-corp year.
• Filed after the 15th day of the 3rd month: The revocation takes effect the first day of the NEXT tax year. For a calendar-year corp, filing on April 1, 2026 means the revocation takes effect January 1, 2027. 2026 stays the last S-corp year.
• Specified prospective effective date: The statement can specify any prospective date on or after the filing date. This is useful for planning. For example: file the revocation June 15, 2026, effective January 1, 2027, to line up with a planned capital raise.

#Shareholder consent mechanics

§1362(d)(1)(B) sets the consent rule. It requires shareholders holding “more than 50 percent of the number of issued and outstanding shares of stock.” This is a vote by share count. Nonvoting shares count too. You do not need every owner to agree. For most owner-operator S-corps with a single owner, the owner alone provides consent.

For multi-owner structures:

• 50/50 owners: both must consent. One alone has only 50%, not “more than 50%.”
• 60/40 owners: the 60% owner can revoke alone, without the 40% owner’s consent.
• 80/15/5 owners: the 80% owner can revoke alone.

A minority shareholder’s lack of consent does not block the revocation. But it can bring other problems: a fiduciary duty claim in some states, a buyout clause in a shareholder agreement, and so on. Always bring in legal counsel for multi-owner revocations.

#Path 2: Involuntary termination under §1362(d)(2)

The S-corp election terminates automatically when the entity stops qualifying as a “small business corporation” under §1361(b). The most common triggers:

1. Ineligible shareholder admitted. A partnership, multi-member LLC taxed as a partnership, or corporation buys shares. Or a nonresident alien gets shares. A nonresident alien cannot be an S-corp shareholder directly. A nonresident alien can hold shares only through one narrow kind of trust, an ESBT. Not through a QSST.

2. More than 100 shareholders. Family-attribution rules under §1361(c)(1) treat family members as one shareholder. So this trigger usually needs either a large estate-planning distribution of shares or the entry of unrelated investors.

3. Second class of stock created. This can happen through terms in your operating agreement, bylaws, or a side letter. These can give some owners different rights to distributions or sale proceeds. Uneven payments alone may need fixing, but usually do not end the election. See the single-class-of-stock article.

4. Ineligible entity type. The corporation becomes a bank using the reserve method, an insurance company taxed under Subchapter L, or a similar excluded entity.

#Effective date

Under §1362(d)(2)(B), termination is effective on the date of the disqualifying event. Say a second class of stock is created on June 15. The S-corp election terminates June 15. Pre-June 15 income is S-corp income. Post-June 15 income is C-corp income (or taxed under whatever regime applies).

#Inadvertent termination relief: §1362(f)

Say the termination was by accident, not on purpose. Say the corporation fixes the cause within a reasonable time. Then the IRS can grant relief, treating the election as never having ended. Fixing an accidental termination usually needs a private letter ruling. The IRS fee is $43,700. Less for small taxpayers. It can take 6 to 18 months. In a few cases the IRS has a simpler path with no ruling.

See the single-class-of-stock article for the §1362(f) cure mechanics.

#Path 3: Involuntary termination under §1362(d)(3)

This path is specific to S-corps with C-corp earnings and profits (E&P) left over from a prior C-corp life. Say the S-corp’s passive investment income tops 25% of gross receipts for three straight tax years. Say the corporation also has accumulated C-corp E&P (earnings left over from its C-corp years) at the end of each of those years. Then the S-corp election ends at the start of the fourth year.

Passive investment income includes rents, royalties, dividends, interest, annuities, and gains from sales of stock or securities. There are exceptions, for rents from operating real estate businesses and for certain royalties.

This trigger is rare in practice. It needs two things at once: C-corp E&P (most S-corps elected from day one and never had C-corp E&P), and a big business shift toward passive income. Most ETS clients run pure operating businesses without this risk.

Say §1362(d)(3) is a risk for you. Planning can avoid it. You can pay out the C-corp E&P, treated as dividends to shareholders, which kills the trigger. Or you can restructure to keep passive income under the 25% line. Or you can accept termination and plan around it.

#Tax-year split: the short-year mechanics

When termination happens mid-year, not on December 31, the year splits into two short tax years:

S Termination Year (S short year): January 1 through the day before termination. Treated as a full S-corp tax year for the period. File Form 1120-S with the corresponding K-1s.

C Short Year: Termination date through December 31. Treated as a C-corp tax year. File Form 1120.

Income is split by days unless you elect to close the books. Say 50% or more of the stock is sold or exchanged during the S short year. Then daily proration is not allowed, and you must close the books.

#Daily proration example

Say an S-corp terminates April 1, 2026, with $480,000 of annual income running evenly throughout the year. Under daily proration:

• S short year (90 days): $480,000 × 90/365 = $118,356
• C short year (275 days): $480,000 × 275/365 = $361,644

The S short year is reported on 1120-S, with K-1 income of $118,356 going to shareholders. The C short year is reported on 1120, with C-corp tax (21% federal) of about $76,000.

#Interim closing of books

Say actual results favor allocating more income to one period or the other. Then you can elect interim closing instead. This requires consent of all shareholders. It gets used most often when:

• Most income was earned in the S short year (lock in pass-through treatment for the larger portion)
• The corporation took a large deduction during one period that should be matched to that period’s income

#What happens after termination: the C-corp world

Post-termination, the entity is taxed as a C-corp by default, unless it elects another classification or dissolves. Consequences:

1. Corporate-level income tax. A 21% federal flat rate applies to corporate taxable income. State corporate tax may also apply.

2. Dividend treatment for distributions. Distributions from the C-corp to shareholders are dividends. They are taxed as ordinary income or qualified dividends. This depends on holding period and corporate-level taxes paid, up to the company’s earnings and profits. Anything above that lowers your stock basis first. Then it becomes capital gain.

3. Double taxation. Income gets taxed at the corporate level. Then again at the shareholder level when paid out. The total effective rate often beats the S-corp pass-through rate by 10 to 20 points.

4. Accumulated Adjustments Account (AAA) treatment. There is a window after termination, the “post-termination transition period.” It runs at least 1 year. Sometimes it runs to the due date of the last S-corp return. In that window, cash distributions up to your AAA are tax-free, if you have enough stock basis. Property does not qualify. The tax-free amount comes out of stock basis first, so distributions above basis are gain. This is a planning window to pull out any remaining S-corp earnings before you shift back to C-corp dividend rules. Use it.

5. Built-in gains tax under §1374 if the entity later re-elects S status (which it can’t for 5 years anyway).

6. Lost QBI deduction: C-corps don’t generate K-1 QBI income.

#The 5-year wait under §1362(g)

Once an S-corp election ends, through any path, the corporation cannot make a new S-corp election for 5 years. The count starts from the termination year. Say an election ends on April 1, 2026. Then the earliest year you can be an S-corp again is 2031. The new Form 2553 would be due by March 15, 2031. IRS consent can allow an earlier date.

#When voluntary revocation is the right call

Three scenarios where revocation makes economic sense:

#Scenario A: Pending capital raise requiring C-corp structure

Outside investors typically want preferred stock. That comes with liquidation preferences, conversion rights, and anti-dilution terms. All of these break S-corp single-class-of-stock rules. Say the capital raise gets funded. Then the S-corp election must end before the preferred instruments are issued. Or the issuance itself triggers automatic termination.

Voluntary revocation ahead of the closing gives a clean switch, with a planned tax-year split. It is often done with a future effective date timed to the closing.

#Scenario B: Sale of the business as asset deal

For many business sales, the buyer prefers to buy assets. This dodges successor liability for unknown debts of the seller corporation. For the seller, an asset sale brings double-taxation problems if the entity is a C-corp. Corporate-level tax on the asset sale gain. Plus shareholder-level tax on the distribution.

Sometimes the seller revokes the S-corp election just before the asset sale closes. This rarely helps, though. The gain still falls at the corporate level under C-corp treatment.

More common is a §338(h)(10) election. It treats the stock sale as a deemed asset sale. The buyer and all of the S-corp’s owners make it together, including owners who are not selling. This does not require revoking the S-corp election. But it does change the tax treatment of the sale. See our S-corp asset vs stock sale guide for the full breakdown.

#Scenario C: Business has shifted to passive income

Say the business has become mainly an investment vehicle: real estate rentals in an S-corp, securities trading, royalty collection. The operational perks of S-corp treatment fade. Distributions get more complex. Basis tracking matters more. And the §1362(d)(3) passive income trigger may kick in.

In these cases, revocation followed by a switch to a different entity structure can simplify things. Often that is a partnership or multi-member LLC for rentals.

#When voluntary revocation is the wrong call

Most other reasons given for revocation are usually wrong:

• “I want to be a C-corp to retain earnings without distributing them”: keeping profits in a C-corp can cost less now. But you pay a second tax when the money comes out. It only works if you will keep the cash in the business for a long time.
• “I’m tired of running payroll”: running payroll and filing an S-corp return add some cost each year. Get a quote before you decide.
• “I want to give my kids stock as gifts”: Your children can own S-corp shares. US citizens and residents are eligible shareholders under §1361(b)(1)(B). Family-attribution rules under §1361(c)(1) treat them as one shareholder for the 100-shareholder count. But that does not change their eligibility.
• “The 1120-S is annoying to file”: annual compliance cost is $2K to $5K. Small next to ongoing tax savings.

Almost every “I want to revoke” conversation we have ends with us recommending against revocation. The exceptions are the three scenarios above.

#The revocation playbook

For clients executing voluntary revocation, here is the workflow:

Phase 1: Decision and modeling (4 to 8 weeks before target effective date):

• Confirm the business reason for revocation
• Model the post-revocation tax structure (C-corp vs partnership conversion vs entity restructuring)
• Calculate the post-termination AAA balance available for tax-free distributions
• Identify any §1362(g) re-election timing implications
• Confirm shareholder consent

Phase 2: Documentation (2 to 4 weeks before target effective date):

• Draft Statement of Revocation with effective date
• Obtain consenting shareholder signatures (more than 50% of stock)
• Prepare board resolution authorizing the revocation
• Plan the post-termination distribution strategy

Phase 3: Filing and execution:

• File Statement of Revocation with IRS service center
• Notify state tax authorities (where state-level S election exists)
• Begin C-corp accounting treatment from effective date
• Process any planned post-termination AAA distributions within the 1-year window

Phase 4: Post-termination compliance:

• File 1120-S for S short year (and pre-revocation year if applicable)
• File 1120 for C short year and going forward
• K-1s for S short year, no K-1s for C short year
• Shareholder personal returns reflect both S short-year K-1 and any C short-year dividends

#Common questions

Can I revoke effective last January 1 (retroactively)? For calendar-year corporations, filing by March 15 makes the revocation effective January 1 of that year. Past March 15, the earliest effective date is January 1 of next year. Unless a later date is specified. True retroactive revocation past the current tax year start isn’t available.

What happens to my AAA after revocation? The Accumulated Adjustments Account from the S-corp period is kept during the post-termination transition period (PTTP). That runs generally 1 year after the termination. Distributions during the PTTP come from AAA first, tax-free up to AAA basis. Then from E&P. Then from basis. After the PTTP, normal C-corp dividend rules apply with no AAA carve-out. Use up AAA distributions in the PTTP.

Can I switch back to S-corp if I change my mind? Yes, but with the 5-year wait under §1362(g). A new Form 2553 cannot be filed for a tax year beginning before the 5th tax year after the termination year. The exception is IRS permission.

Does revocation affect basis? Stock basis switches from S-corp basis tracking to C-corp basis. Final S-corp basis as of the termination date becomes the C-corp basis going forward. Future C-corp distributions cut basis dollar-for-dollar, similar to S-corp mechanics, until basis runs out.

What about loss carryforwards? Suspended losses stay alive for the post-termination transition period, usually 1 year. You can use them if you add basis by then, for example with a cash contribution or a direct loan. Do not take distributions, because they lower basis. Losses left over after that period are lost.

Can I revoke an S-corp election that’s been in effect for less than a year? Technically yes, though the IRS may question whether the original election was made in good faith. New-entity revocations within the first year are rare. They usually signal either a planning mistake or a big change in business plan.

What if my fiscal year is non-calendar? The 15th day of the 3rd month rule applies to your fiscal year, not the calendar year. Take a corporation with a June 30 fiscal year-end. Revocation by September 15 is effective July 1, the start of the fiscal year. Past September 15, it is effective July 1 of the next fiscal year.

Does revocation trigger built-in gains tax? No. Built-in gains tax under §1374 applies to former C-corps that became S-corps. It hits appreciated assets at the time of S-corp election. Revocation of an S-corp election goes the other way, S to C. It doesn’t trigger §1374.

What about state-level S-corp elections? A few states, such as New York, still have their own S-corp election (CT-6). New Jersey also still has a separate election (CBT-2553). Arkansas dropped its separate requirement for tax years beginning in 2018 and later. The federal election is binding there. Federal revocation alone doesn’t end a state-level S election where one exists. Check your state’s rules before you revoke.

How does revocation interact with shareholder agreements? Most well-drafted shareholder agreements require shareholder consent or specific votes for any change in entity tax structure. Review the agreement before filing revocation. Multi-owner revocations without proper authorization can create breach-of-contract claims.

Say you’re thinking about an S-corp termination. Maybe for a sale, a capital raise, a business pivot, or another reason. The Discovery call is where we model the post-revocation structure, the AAA distribution timing, and the 5-year wait implications. Most “should I revoke?” conversations end with “don’t.” But the ones that should revoke benefit hugely from getting the mechanics right. We don’t do surprises. You’ll see the modeled tax outcome before any statement is filed. Free advice either way.
