How to Revoke an S-Corp Election: Deadlines, the 5-Year Lockout, and the LLC Trap (2026)

Two years ago your consulting practice cleared $150,000 and the S-Corp election was an easy yes. Then the anchor contract ended. This year you will be lucky to see $40,000 of profit, and you are still paying for payroll software, still filing quarterly Forms 941, and still paying someone to prepare an 1120-S every spring. This owner is theoretical, but the situation is common. An election that saved real money at one income level has turned into pure overhead at another. Revoking it is allowed, and the paperwork is easy. The exit just has three traps that matter more than the letter itself.

The math that says it is time

An S-Corp saves money one way: profit taken as distributions escapes the 15.3% self-employment tax under IRC §1401 that a sole proprietor pays on nearly everything. At $150,000 that spread is worth thousands. At $40,000 it collapses. Suppose reasonable compensation for the work is $28,000. A sole proprietor pays $5,652 of SE tax on $40,000 of profit. The S-Corp pays $4,284 of combined FICA on the $28,000 salary, so the election saves $1,368 of payroll tax. Then the costs eat it. Payroll software runs about $550 a year. An 1120-S costs more to prepare than a Schedule C, call it $600 extra. And the QBI deduction shrinks, because W-2 wages are not qualified business income. The sole proprietor deducts about $7,435 under §199A while the S-Corp owner deducts about $1,853, which costs roughly $670 of extra tax in the 12% bracket. Here is that ledger.

The break-even moves with your salary, your bracket, and your state, so run your own numbers through the savings math before you file anything. If the election loses money two years running and you do not expect a rebound, keep reading.

How do I revoke an S-Corp election?

There is no IRS form for a revocation. You file a signed written statement with the IRS service center where the corporation files its Form 1120-S, stating that the corporation revokes its election under IRC §1362(a), and you attach consents from shareholders holding more than half of the outstanding shares. That consent threshold comes straight from §1362(d)(1)(B), and it counts non-voting shares. Under Treas. Reg. §1.1362-6(a)(3), summarized on the IRS page for revoking a Subchapter S election, the statement also lists the number of shares issued and outstanding and the effective date, and each consenting shareholder signs. For a single-owner company this is a one-page letter plus one consent. Mail it certified and keep a copy. If your state has its own S election, New York and New Jersey both do, the state revocation is a separate filing.

When is the deadline to revoke an S-Corp election?

Timing decides which year the revocation covers. To make a revocation retroactive to January 1, IRC §1362(d)(1)(C) requires you to file it by the 15th day of the third month of that tax year, which for a calendar-year 2026 revocation meant March 16, 2026, since the 15th fell on a Sunday. A revocation filed after that date takes effect on January 1 of the following year unless you specify a prospective effective date. So a statement mailed this July with no date named takes effect January 1, 2027. You could instead name a mid-year date like August 1, 2026, but I would not. That splits the year into an S short year and a C short year under §1362(e), two returns, allocated income, and prep fees that swamp whatever you were trying to save. File now, name January 1, 2027, and run payroll normally through December.

What happens to my LLC after I revoke the S election?

Here is the trap almost nobody sees coming. Most small S-Corps are really LLCs that filed Form 2553, and under Treas. Reg. §301.7701-3(c)(1)(v)(C) that filing is also a deemed election to be classified as a corporation. Revoking the S election only undoes the S part. An LLC that elected S status is treated as having elected corporate classification, so revoking the S election leaves you with an LLC taxed as a C corporation, and getting back to disregarded status requires a Form 8832 election that the IRS treats as a corporate liquidation. That deemed liquidation triggers gain at the corporate level under IRC §336 and at the shareholder level under IRC §331 on any appreciated assets. For a cash-basis consultant whose assets are a laptop and a checking account, that gain usually rounds to zero, but a company holding appreciated equipment, real estate, or self-created intangibles needs to price the exit first. Watch the 60-month rule too. An entity that changed its classification by election generally cannot change again for 60 months under Reg. §301.7701-3(c)(1)(iv), though an election that was effective from the entity's formation date does not start that clock.

What is the post-termination transition period?

There is one gift in this process. The post-termination transition period is a window defined in IRC §1377(b) that runs from the day after your last S corporation day until at least one year later, or the due date of the final S-Corp return including extensions if that is later. During that window, IRC §1371(e) lets the corporation distribute its accumulated adjustments account in cash tax free to the extent of stock basis. Miss the window and those same dollars come out of a C corporation as dividends, taxed a second time. The distribution must be cash, and it is capped at your stock basis, one more reason your Form 7203 needs to be current before the final 1120-S goes in.

Can I re-elect S-Corp status after revoking?

Not right away. IRC §1362(g) blocks a new S election until the fifth taxable year after the first year the revocation is effective, unless the IRS consents to an earlier election. Revoke effective January 1, 2027 and the earliest automatic re-election covers 2032. That lockout is the real price, and it is why I treat revocation as a last resort, not a reaction to one slow year. If profit might rebound inside a year or two, the cleaner play is usually to keep the election and reset the salary to a number that matches the reduced workload. Reasonable compensation scales with the work, and a lower salary shrinks the payroll tax while you wait.

What I would actually do

Run the numbers twice, a year apart, before revoking. One bad year is a salary conversation. Two bad years with no pipeline is a revocation, filed with a January 1 effective date, followed by the Form 8832 analysis and a plan to sweep the AAA out in cash during the transition period. If you are still on the other side of this decision, wondering whether to elect at all, the EntityIQ calculator weighs the savings against payroll and filing costs at your actual profit level. That is the test the theoretical owner above should have rerun every January.
