FOR STARTUP FOUNDERS
The S-corp election most founders think they missed, and didn't.
I've sat across from a dozen founders who assumed the window on the 2553 form had already closed. It hadn't. This is the story of the one who called in September instead of waiting for another April surprise.

The Story
Jonah Reyes runs a 12-person SaaS company that crossed $410,000 in revenue last year. He was still paying himself as a sole owner, no S-corp, no payroll, just distributions whenever cash allowed. In September, his bookkeeper ran his Q3 estimate: $31,000 due, most of it self-employment tax on profit he'd already spent building the product. He thought the fix, the 2553 form, had a deadline he'd blown past back in March.
The Problem
The IRS wants your S-corp election, Form 2553, filed within a narrow window early in the tax year, or anytime the year before. Miss it and most founders assume they're stuck paying 15.3% self-employment tax on every dollar of profit until next January. Spreadsheets don't flag this. TurboTax doesn't ask about it. And a generalist CPA who files one return a year for you has no incentive to chase an entity election that only pays off in the following filing season.

What We Tried
He'd filed the LLC formation paperwork himself, opened a business bank account, and used the same CPA for three years, the one who filed his return every April and never once brought up Form 2553. He never ran payroll, never elected S-corp status, and never heard the term reasonable salary until self-employment tax caught up to him in one lump sum.

The Discovery
Here's what Jonah's old CPA never told him: the IRS allows late S-corp elections under Rev. Proc. 2013-30 if you have reasonable cause and file within a few years of the intended effective date. We filed his Form 2553 in September with a reasonable-cause statement attached, electing S-corp status retroactive to January 1st of that same year. If the missed deadline was this year's, filing now can still catch the whole year retroactively; if it slipped last year too, only the current year is still reachable and the prior year is gone for good. The IRS accepted it without penalty and without requiring an amended entity.

The FixAMADAE
Amadae found the late-election window because entity structure gets reviewed before a single receipt does, not after. We filed the 2553 form, built the reasonable-salary payroll behind it, and set his quarterly estimates so the next $31,000 bill never shows up unannounced. Books, payroll, and tax strategy come from one team for a flat monthly fee, not a CPA who only shows up in March.

The Proof
Jonah's Q1 estimate this year came in at $6,200, not the $9,000-plus he used to pad for surprises. He hasn't opened a spreadsheet since.

Why NowAMADAE
Late S-corp elections work best the further you are from January, not closer, because the IRS wants to see you acted once you realized the mistake. Wait until December and you're explaining a nine-month delay instead of a six-month one. File now and you can still elect S-corp status retroactive to this January, cutting a full year of self-employment tax instead of starting fresh next spring. The call is free and there's no contract, so the only real cost of waiting is the tax bill you already know is coming.

Straight answers
Yes, if you have reasonable cause and file within a few years of your intended effective date. Relief is not indefinite, the sooner you file once you realize the deadline was missed, the stronger the reasonable-cause case, and the IRS grants it routinely under Rev. Proc. 2013-30 when the paperwork is filed correctly the first time.
Ask them if they've filed a late election with reasonable-cause relief before. Many generalist CPAs never have, because it's a once-a-year event they don't specialize in. We file these regularly and know exactly what the IRS wants to see.
No. A properly documented late Form 2553 is a standard IRS process, not a red flag. The real risk isn't the election, it's leaving self-employment tax on the table while you wait.
The math works well before six figures in profit. If your business nets more than roughly $60,000 to $80,000 a year, the self-employment tax savings usually outweigh the payroll and filing costs.
