You elected S corporation status years ago because it saved you money — no double tax, one layer of tax, profits flowing straight to your return. But now the math looks different. Maybe you're retaining earnings to fund growth and paying individual rates on money you never took home. Maybe a venture fund wants in and can't hold S corporation stock. Or maybe the flat 21% C corporation rate suddenly beats what you and your shareholders pay on pass-through income.
Whatever the reason, here's the part most owners miss: leaving S status is not the mirror image of electing it. Electing takes one form and unanimous consent. Leaving takes a precisely worded statement, a majority of your shares behind it, a deadline measured in days — and it can lock you out of S status for five years while a built-in gains tax follows you out the door.
This guide walks through when revoking makes sense, exactly how to do it, and the traps that catch owners on the way out.
Why Owners Revoke: When C Corporation Status Wins
Revocation is a dollars-and-sense decision. The common reasons owners choose to become a taxable C corporation:
You're paying tax on money you never received. S corporation shareholders owe tax on their share of profits whether or not the cash is distributed. If your company retains most earnings to fund equipment, inventory, or expansion, you can owe individual tax at rates up to 37% on income sitting in the company's bank account. A C corporation pays a flat 21% on retained earnings instead — and nobody owes tax until dividends are actually paid.
The QBI deduction doesn't fully close the gap. Pass-through income may qualify for the 20% qualified business income deduction, which brings the top effective rate to roughly 29.6% — still above 21%. And specified service businesses lose the deduction above income thresholds, which makes the C corporation rate look better still.
You need investors the S rules forbid. S corporations are limited to 100 shareholders, one class of stock, and only eligible shareholders — no partnerships, corporations, or nonresident aliens as owners. Venture capital funds, private equity, and foreign investors generally can't hold S stock. If raising capital means bringing in an ineligible investor, the S election has to go — voluntarily by revocation, or involuntarily the day the disqualifying shareholder takes stock.
Fringe benefits work better in a C corporation. Owner-employees of a C corporation can receive health insurance, group term life, and other fringe benefits tax-free and fully deductible by the company. Shareholders owning more than 2% of an S corporation get far stingier treatment — many of those same benefits become taxable wages to them.
You want a fiscal year or a cleaner exit. C corporations can generally choose any fiscal year-end, while S corporations are stuck with a calendar year unless they make a special election and post a deposit. Some owners also revoke ahead of a sale so the buyer acquires C corporation stock with its own planning advantages.
Run the numbers both ways before you act — and model the double-tax cost of eventually getting cash out of the C corporation as dividends. Revocation trades one layer of tax now for two layers later. It wins when you plan to retain and reinvest for years, not when you distribute everything annually.
The Mechanics: How a Revocation Actually Works
There is no IRS form for revoking an S election. You do it with a signed written statement mailed to the service center where you file your corporate return. The IRS publishes exactly what that statement must contain, and missing an element can invalidate the revocation — so treat this as a checklist, not a letter.
What the statement must include
Your revocation statement needs each of the following:
- A declaration that the corporation revokes its election under Section 1362(a)
- The name, address, and taxpayer identification number of each consenting shareholder
- The number of shares each consenting shareholder owns
- The corporation's employer identification number
- Identification of the election being revoked
- The signature of each consenting shareholder, signed under penalties of perjury
- The effective date of the revocation (or a prospective date)
- The signature of a person authorized to sign the corporate return
Who must consent
Shareholders holding more than 50% of the issued and outstanding shares — voting and nonvoting alike — must consent at the time the revocation is made. Note the asymmetry with electing: making the S election requires every shareholder's consent, but revoking it takes only a majority. A minority shareholder cannot block a revocation, and a 50-50 deadlock cannot produce one — "more than half" means 50% plus at least one share.
When it takes effect
Timing is everything, because the effective date decides which tax year the S election dies in:
- To revoke effective the first day of the tax year, the statement must reach the IRS by the 15th day of the third month of that year. For a calendar-year corporation, that means March 15 for a January 1 effective date.
- To revoke effective any other day, the statement must be received by the IRS no later than the requested effective date. A calendar-year corporation requesting a February 14 effective date must get the statement to the IRS by February 14.
Miss the March 15 deadline for a beginning-of-year revocation and you generally get a mid-year effective date instead — which splits your year into two short tax years (more on that below), rather than the clean break you wanted.
You can take it back — briefly
A revocation can itself be rescinded, but only before the revocation becomes effective and only with the consent of every person who consented to the revocation plus every person who became a shareholder in the meantime. Once the effective date passes, the election is dead and the five-year clock starts.
The Mid-Year Split: Life With Two Short Years
When a revocation takes effect on any day other than the first day of the tax year, the year is divided into an S short year and a C short year. Income for the full year is generally allocated day by day between the two periods — so if your revocation is effective October 1, roughly three-quarters of the year's income lands in the S short year and flows to shareholders, while the rest is taxed to the new C corporation.
Shareholders can instead elect to close the books on the revocation date and measure each period's actual income, but that election requires the consent of every shareholder who held stock at any point during the S short year plus the corporation itself. The day-by-day default is simpler; the closing-of-books election is fairer when income is seasonal or lumpy — for example, a retailer revoking just before the holiday quarter.
Either way, expect to file two short-year returns and to explain the split to every shareholder receiving a Schedule K-1 for the S portion. Warn your shareholders early: they still owe tax on the S short-year income even though the company is now a C corporation.
The Five-Year Lock-In
This is the trap that surprises owners most. Once your S election terminates — by revocation or otherwise — neither your corporation nor any successor corporation may make a new S election until the fifth taxable year beginning after the first year the termination was effective, unless the IRS affirmatively consents. In practice, that is five full tax years of C corporation life before you can come back.
There are narrow exceptions. No IRS consent is needed to re-elect within five years if the termination happened because the corporation revoked effective the very first day its election was ever to take effect, or because it failed to qualify as a small business corporation on that first day. Inadvertent terminations can also be cured with relief. But a deliberate mid-life revocation followed by seller's remorse? You will need to request a private letter ruling and persuade the IRS — an expensive, uncertain process with the burden of proof on you.
Before you revoke, ask the question in reverse: is there any realistic scenario in which you want S status back within five years — a future sale structured around pass-through treatment, a change in tax rates, a falling-out with the new investor? If the answer is maybe, revocation may be the wrong tool. Fix the underlying problem another way first.
The Built-In Gains Tax That Follows You Out
Here is the second surprise. A C corporation that used to be an S corporation can owe corporate-level tax on gains that were already baked into its assets on the day it converted. Under Section 1374, if the former S corporation sells or distributes appreciated property during the five-year recognition period after the revocation's effective date, the built-in gain — the appreciation that existed while it was still an S corporation — is taxed to the corporation at the 21% corporate rate.
Work through what that means. Your S corporation owns a building bought for $400,000 now worth $1 million. You revoke, and two years later the C corporation sells it. The $600,000 of appreciation that accrued during the S years is hit with corporate tax at the entity level, and the after-tax proceeds are taxed again when distributed to you as dividends. Had you sold while still an S corporation, that gain would have flowed through once at shareholder-level rates.
Planning points:
- Inventory the appreciation before you revoke. Get a realistic valuation of appreciated real estate, equipment, and intangibles, and map which assets you might sell within five years.
- Consider selling first, revoking second. Disposing of highly appreciated assets while still an S corporation keeps the gain at one layer of tax.
- Watch distributions of appreciated property too. Distributing appreciated property out of a C corporation triggers gain recognition just like a sale.
- LIFO recapture is a related sting. A C corporation using LIFO that converts from S status faces a recapture amount picked up in income — another reason to quantify everything before the effective date.
Getting Your AAA Out: The Post-Termination Window
Not all the news is bad. When your S election ends, your accumulated adjustments account — the running total of S corporation income that shareholders already paid tax on — doesn't vanish. During the post-termination transition period, generally about one year after the last S corporation year, cash distributions to shareholders come out of that AAA balance tax-free (to the extent of each shareholder's stock basis), instead of being taxed as dividends out of C corporation earnings.
This window is use-it-or-lose-it. After it closes, normal C corporation ordering takes over — distributions are taxable dividends to the extent of accumulated earnings first, then tax-free return of stock basis, then capital gain — and the AAA balance is effectively stranded. So build a distribution plan before you revoke: quantify AAA, confirm shareholder stock bases, and schedule the AAA payout inside the window. Shareholders who already paid tax on those earnings shouldn't face dividend tax on them a second time just because the calendar ran out.
One related trap for cash-method companies: converting to a C corporation can force a change to the accrual method of accounting, with a Section 481(a) adjustment spreading the income catch-up over several years. Model that adjustment in your first-year C corporation tax projection so estimated payments don't come up short.
A Practical Revocation Checklist
Pulling it together, here is the sequence to follow:
- Model both worlds. Compare total tax as an S corporation (shareholder rates on all income, distributed or not) against life as a C corporation (21% entity tax plus eventual dividend tax), over a multi-year horizon that matches how long you'll retain earnings.
- Inventory the exit costs. Value appreciated assets for the Section 1374 five-year exposure, quantify AAA and shareholder stock bases for the post-termination distribution window, and estimate any accounting-method adjustment.
- Line up the votes. Confirm shareholders holding more than half the outstanding shares — voting and nonvoting — will sign under penalties of perjury. Remember a 50-50 split can't revoke.
- Pick the effective date deliberately. January 1 with delivery by March 15 gives the cleanest break. A mid-year date splits the year and complicates every shareholder's return.
- Draft the statement to the IRS checklist. Include every required element, both shareholder and corporate signatures, and the effective date. Send it to the service center where you file, with proof of delivery.
- Plan the AAA distribution window. Schedule tax-free AAA payouts within the post-termination transition period before the window closes.
- Reset compliance. New estimated-payment schedule at the corporate level, payroll and fringe-benefit elections revisited, fiscal-year options reconsidered, and shareholder communications explaining the S short-year K-1.
- Calendar the five-year bar. Note the earliest year you could re-elect without IRS consent, and document the business reasons for the revocation while memories are fresh — you'll want that record if you ever request early re-election relief.
Keep Your Entity Decisions Grounded in Good Books
Choosing between S and C status is ultimately a numbers game — retained earnings, distribution plans, asset appreciation, shareholder bases — and every input to that model comes from your books. The owners who get this decision right can point to a clean balance sheet, a reliable AAA history, and per-asset records that make the built-in gains analysis straightforward. The ones who get it wrong are usually guessing at those numbers.
Beancount.io gives you plain-text accounting that's transparent, version-controlled, and AI-ready, so your entity analysis rests on records you can actually trust. Get started for free and keep the books that make big tax decisions easy.
