Do You Have to File Form 2553 Every Year? S Corp Filing Rules

No, you do not have to file Form 2553 every year. The Election by a Small Business Corporation is a one-time filing: once the IRS accepts it, your S corporation status carries forward automatically to every future tax year until something specifically ends it.¹ What you do file every year is Form 1120-S, the S corporation’s annual income tax return. Confusing the two is common, and the difference matters because the yearly work sits with the 1120-S, not the 2553.

Why Form 2553 Is One and Done

Form 2553 tells the IRS your eligible corporation or LLC wants to be taxed under Subchapter S of the Internal Revenue Code.² The election takes effect for the tax year you specified on the form and then continues indefinitely.³ There is no renewal cycle. There is no annual checkbox. There is no confirmation form the IRS expects you to send in each spring.

After the initial filing, the IRS sends a notice — usually within 60 days — telling you whether the election was accepted and when it takes effect.¹ Keep that acceptance letter permanently. Years later, the IRS may question your status or a state tax agency may ask for proof of your federal election, and that letter is often the cleanest evidence.

The Return You Actually File Each Year: Form 1120-S

The annual obligation that gets mistaken for Form 2553 is Form 1120-S, the U.S. Income Tax Return for an S Corporation. It’s due by the 15th day of the third month after your tax year ends, which is March 15 for calendar-year filers.⁴ The return reports the corporation’s income, deductions, and credits even though the entity itself generally owes no federal income tax; the items pass through to shareholders instead.

Along with the return, the corporation prepares a Schedule K-1 for every person who held shares at any point during the year.⁴ Each K-1 shows a shareholder’s allocated income, losses, and credits, which that shareholder then reports on Form 1040. Shareholders owe tax on their share whether or not the corporation actually distributed cash.

Extensions

Can’t hit March 15? Filing Form 7004 before the due date gives you an automatic six-month extension, moving the deadline to September 15 for calendar-year corporations.⁵ The extension covers the return only, not any tax owed. Shareholders still need their K-1s in time to file their personal returns, so extending the corporate return often triggers personal extensions too.

Late-Filing Penalties

Missing the deadline without an extension gets expensive quickly. For returns required to be filed in 2026, the penalty is $255 per shareholder for each month or partial month the return is late, up to 12 months. A four-shareholder S corp that files three months late owes $3,060 in penalties before any tax question is settled. If the return is more than 60 days late, the minimum penalty is the lesser of the tax due or $525.⁴ Reasonable cause can get the penalty waived, but forgetting rarely qualifies.

What Can End Your Election Even Though You Never Refile

The reason there’s no annual Form 2553 is that Subchapter S status is structural: it persists as long as the corporation keeps meeting the requirements in IRC §1361. Break one of them, even briefly, and the election terminates automatically on the date of the disqualifying event.³ The core rules to watch:

No more than 100 shareholders. Family members can elect to be treated as a single shareholder, which provides some cushion, but crossing 100 ends the election.⁶
Only eligible shareholders. Shareholders must generally be individuals who are U.S. citizens or resident aliens. Estates, certain trusts, and certain tax-exempt organizations also qualify. Other corporations, partnerships, and nonresident aliens do not.⁶
One class of stock. All outstanding shares must carry identical rights to distributions and liquidation proceeds. Differences in voting rights alone don’t disqualify the corporation, but unequal economic rights do.⁶

The shareholder-type rule catches people off guard. An angel investor operating through an LLC taxed as a partnership can’t hold shares in your S corp. Neither can a venture capital fund organized as a corporation. If someone in that category picks up even a single share, the election terminates that day and the company reverts to C corporation taxation.

The Passive Investment Income Trap

A less obvious termination trigger applies only to S corps that carry accumulated earnings and profits from a prior period as a C corporation. If the company has C corp earnings and profits at the close of three consecutive tax years, and passive investment income exceeds 25 percent of gross receipts in each of those years, the election terminates automatically.³ This mostly hits businesses that converted from C to S and still hold old retained earnings. The fix is to distribute those earnings or keep passive income under the threshold.

Five-Year Lockout After Termination

If your election ends for any reason, whether by an eligibility failure or a voluntary revocation, the corporation generally cannot re-elect S status for five tax years.³ The IRS can waive this waiting period, but only if you show the termination resulted from circumstances that were not reasonably within your control. That’s a high bar, which is why preventing an accidental termination matters far more than trying to undo one.

Voluntarily Revoking S Corp Status

If S corp taxation stops making sense, you can revoke the election by filing a written statement with the IRS service center where you submit your annual return. Shareholders holding more than 50 percent of the issued and outstanding shares must sign the statement, and it must include each consenting shareholder’s name, address, taxpayer identification number, and the number and acquisition date of their shares.⁷

Timing matters. If you file the revocation 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 tax year, letting you make the switch retroactive to January 1.³ File after March 15 and the revocation doesn’t kick in until January 1 of the following year, unless you specify a later prospective date in the statement. Planning the effective date carefully avoids a messy split year with both S corp and C corp short periods.

States Handle S Status Separately

The federal election is only one layer. Most states automatically recognize your federal S election and tax the corporation accordingly, but a handful require a separate state-level S election, and a few don’t recognize S corp status at all for state tax purposes. Some states also impose their own entity-level taxes on S corporations while still honoring the pass-through structure for income tax. After you receive federal approval, check with your state’s department of revenue to confirm whether any additional filings or payments apply.
