Getting Form 2553 in the mail feels like the finish line. It's actually the starting line. The IRS can — and does — revoke S-corp elections over compliance failures that show up weeks or months after the filing, and plenty of business owners don't find out something went wrong until it's already cost them money. The election isn't self-sustaining. It has to be maintained.

Here's the checklist worth working through once that form is filed.

Step 1: Confirm the IRS Actually Accepted It

Don't assume silence means approval. The IRS typically issues a CP261 notice for a new S-corp election (or a CP263 for annual confirmations) that acknowledges your election and its effective date.

If you filed Form 2553 alongside your initial Form 1120-S, or if 60 days have passed with no CP261 in hand, call the IRS Business and Specialty Tax Line directly rather than waiting it out.

Worth checking:

• You've actually received a CP261 or equivalent acknowledgment

• The effective date on that notice matches the date you intended

• If you used the late-election relief under Revenue Procedure 2013-30, that your reasonable-cause explanation was actually accepted

If a registered agent handles your mail, loop them in to confirm this specific notice was received and forwarded promptly — missed IRS correspondence is one of the most common ways business owners discover an election problem long after it's become one.

Step 2: Update What the IRS Has on File for Your EIN

Your EIN itself doesn't change when you elect S-corp status — but the classification tied to it does, and the IRS needs its records to reflect that. This is also a good moment to get your home address off IRS correspondence entirely; a registered agent address or dedicated business mailing address reduces both missed-notice risk and unnecessary privacy exposure.

What to handle:

• File Form 8822-B if you've moved, or if you're now routing mail through a registered agent or privacy address

• Confirm your entity's legal name matches exactly what's on file — mismatches are a frequent cause of processing delays and rejected filings

• Report any change in responsible party within 60 days, also via Form 8822-B

Step 3: Get Payroll Actually Running for Owner-Employees

This is the step that matters most, and the one most likely to get you in trouble if skipped. Any owner-employee actively providing services to the business needs a genuine reasonable salary — real W-2 wages, with payroll taxes properly withheld and remitted. Skipping this, or setting the salary too low, is one of the most common triggers for an IRS audit of an S corp. Get reclassified, and you're looking at back payroll taxes plus interest and penalties.

What needs to be in place:

• Payroll tax accounts registered with both the IRS (via EFTPS) and your state

• A documented, defensible reasonable-compensation figure — benchmarked against what you'd pay someone else to do your job in your industry and market, with your reasoning written down

• Actual payroll processing, whether through software or a payroll service

• Federal income tax withholding plus Social Security and Medicare (FICA) withheld and deposited on schedule

• Form 941 filed every quarter

Step 4: Make Sure Your State-Level Records Match Your Federal Election

The S-corp election is a federal tax classification — your entity still exists, and still has obligations, under state law. Most states require a registered agent maintaining a physical in-state address to receive legal and government notices, and states can administratively dissolve an entity that lets that lapse or misses an annual report. An administrative dissolution at the state level can put your federal S-corp election at risk too.

Worth confirming:

• Your registered agent designation is current with your Secretary of State

• Your registered address is somewhere mail will actually reach you

• Whether your state layers on any additional requirements specific to S corporations

• If you formed in one state (Delaware, Wyoming) but operate in another, that your foreign qualification filings in your home state are current

If you're still acting as your own registered agent, an S-corp election is a natural moment to switch to a professional service — one that reliably catches compliance notices and service-of-process documents and gets them to you promptly.

Step 5: Adjust Your Bookkeeping to Match S-Corp Requirements

S corporations carry bookkeeping obligations that don't exist for a partnership or sole proprietorship:

• Separate salary from distributions in your books — they're taxed differently and need to be tracked as distinct categories, not blended together

• Track each shareholder's stock basis — basis determines how losses are treated and shapes the tax consequences of distributions

• Maintain the Accumulated Adjustments Account (AAA) — this represents previously taxed S-corp earnings that can generally be distributed tax-free

• Keep distributions proportionate to each shareholder's ownership percentage — disproportionate distributions are one of the conditions that can actually terminate the election

Step 6: File Form 1120-S — Every Year, No Exceptions

S corporations file their own federal return, Form 1120-S, regardless of whether any tax is owed at the entity level. It's due March 15 of the following year, with a six-month extension available via Form 7004. Miss the deadline, and the IRS applies a per-shareholder, per-month late-filing penalty that adds up faster than most owners expect.

Step 7: Keep Meeting the Ongoing Eligibility Rules

S-corp status isn't a one-time qualification — it's a standard you have to keep meeting every year the election stays in place. Violating any of these terminates the election automatically:

• No more than 100 shareholders

• Every shareholder must be a U.S. citizen or resident alien

• Only one class of stock

• The entity must be a domestic corporation, or an LLC that has elected corporate treatment

Frequently Asked Questions

How long does the IRS take to process Form 2553? Typically four to six weeks before a CP261 notice arrives. Past 60 days with no confirmation, call the IRS Business and Specialty Tax Line directly.

Can the election be made effective for a prior tax year? Sometimes. Revenue Procedure 2013-30 offers relief for late elections when the entity can show reasonable cause and meets certain conditions — but this relief isn't automatic; it has to be requested and accepted.

What actually happens if my salary is too low? If the IRS audits and determines your compensation was unreasonably low relative to your role, it can reclassify distributions as wages — triggering back payroll taxes, interest, and potentially significant penalties.

Does the federal election automatically update my state records? No. Your S-corp election is purely a federal tax classification. Your registered agent status, entity standing, and any state-level elections need to be separately confirmed as current with your state.

What can terminate an S-corp election? Termination can be voluntary or involuntary. Involuntary terminations happen when the entity stops meeting eligibility rules — a non-qualifying shareholder, exceeding 100 shareholders, or issuing a second class of stock, among other triggers.

The Bottom Line

Filing Form 2553 is genuinely just the opening move. The real work — confirming acceptance, getting payroll properly running, keeping your state filings current, adjusting your books, and filing on time every year — is what actually keeps the election intact long-term. Treat the months right after filing as seriously as the filing itself, and the election does what it was meant to do: legitimately reduce your tax burden without creating a compliance problem that costs more than it saved.
