Here is the direct answer for how to check S corp status online: the IRS does not offer a public online tool that shows whether your federal S corporation election was accepted. The reliable options are your IRS acceptance notice, a call to the IRS Business & Specialty Tax Line, or indirect proof from IRS tax records.
Key Takeaways
- There is no free or paid IRS website where you can look up S corp status by business name or EIN.
- The fastest reliable method is to call the IRS Business & Specialty Tax Line at 800-829-4933 with your EIN and business information ready.
- The CP261 notice is the IRS acceptance notice for Form 2553, and a CP264 notice means the election was not accepted.
- If the CP261 is lost, an authorized person can ask the IRS for written verification of the S election.
- The IRS generally responds to Form 2553 within about 60 days, so silence after that point is a reason to follow up.
- Accepted Form 1120-S filings and business tax transcripts can support that the IRS treats the company as an S corporation.
- State records can show entity status or state tax status, but they do not prove the federal S corporation election.
Why You Cannot Check S Corp Status Online
The phrase check S corp status online sounds simple, but the IRS does not publish S corporation election records in a searchable database. Your S election is part of your federal tax account. Federal tax information is confidential, so the IRS does not let the public search by EIN, company name, officer name, or state registration number to confirm S corp status.
This creates a common search problem. State business search pages can confirm that a corporation or LLC exists, is active, or is in good standing with the Secretary of State. Those records do not show whether the IRS accepted Form 2553. A business can be active with the state and still be taxed as a C corporation, partnership, disregarded entity, or S corporation for federal tax purposes.
Third-party lookup sites have the same limitation. They may pull state registration data, registered agent information, or entity formation details, but they do not have access to IRS election records. If a website promises an instant S corp status lookup, treat the result as state or public-record information only.
The closest online evidence comes from IRS business tax records, such as transcripts showing processed Form 1120-S filings. That is not a public lookup tool, and it usually requires account access or help from a tax professional. For a direct answer, use the IRS letters and phone process below.
Fastest Free Method: Call the IRS
The fastest free way to check S corp status is to call the IRS Business & Specialty Tax Line at 800-829-4933. The line is for business tax account questions, including whether the IRS received and accepted Form 2553. The IRS lists the line as open Monday through Friday, 7 a.m. to 7 p.m. local time.
The IRS will not give tax account information to just anyone. The caller should be an owner, officer, partner, or another person the IRS recognizes as authorized. A CPA, attorney, or other representative may be able to call if the proper authorization is already on file.
Before you call, gather the basic account details. Have your EIN, the business legal name, the business address on IRS records, and your name and title. If the company changed names or moved after getting its EIN, have the old and new information available so the agent can match the account.
Ask direct questions. First, ask whether Form 2553 is on file. Second, ask whether it was accepted. Third, ask for the effective date of the S corporation election. If the agent confirms the election, ask for written confirmation to be mailed to the address on file. A verbal answer helps you plan, but written IRS confirmation is better for banks, investors, buyers, and tax records.
| Question to Ask | Why It Matters |
|---|---|
| Was Form 2553 received? | Confirms the IRS has the election request on the business account. |
| Was the election accepted? | Confirms the company has federal S corporation tax status. |
| What is the effective date? | Shows when payroll, distributions, and filings should match S corp treatment. |
| Can you send written confirmation? | Creates proof if the original acceptance notice is lost. |
IRS Letters That Prove Form 2553 Was Accepted
The best proof of S corp status is the IRS acceptance notice for Form 2553. The notice is called CP261. It confirms that the IRS accepted the election and states the effective date. If you have a CP261 in your formation file, tax file, or accountant's records, you have the strongest answer to the question, how do I know if my S corp election was accepted?
Keep the CP261 permanently. It is not just a tax-season letter. Banks, lenders, buyers, investors, payroll providers, and accountants may ask for proof that the business is taxed as an S corporation. A copy of the filed Form 2553 helps, but it only proves that you prepared or submitted the election. The CP261 proves the IRS accepted it.
If the IRS did not accept the election, it may issue a CP264 notice. That notice means the election failed. Read the reason carefully. Common issues include missing shareholder consent, late filing, ineligible shareholders, tax-year problems, or other errors on the form. A rejected election should be addressed before you keep filing or operating as if S status is settled.
If you lost the CP261, call the IRS and ask for written verification of S corporation status. The IRS may provide a verification letter instead of reissuing the original notice. Keep that letter with your corporate records and scan a digital copy.
| Document | What It Shows | How to Use It |
|---|---|---|
| Form 2553 | The business requested S corporation tax treatment. | Keep it with signatures and proof of mailing or faxing. |
| CP261 | The IRS accepted the S corporation election. | Use it as primary proof of S corp status. |
| CP264 | The IRS did not accept the election. | Fix the problem before relying on S corp treatment. |
| IRS verification letter | The IRS has S status on record. | Use it when the CP261 is missing. |
No Response to Form 2553 Yet?
The IRS generally sends a decision letter within about 60 days after Form 2553 is filed. If you requested a special tax year or the form needs extra review, the process can take longer. Still, if more than about 60 days have passed and you have not received a CP261 or CP264, follow up.
Start by confirming that the election was actually sent. Form 2553 is not filed through a public online tracker. The form is mailed or faxed, and all shareholders must sign where required. Your best filing evidence is a certified mail receipt, approved delivery service record, fax confirmation page, or a copy retained by the person who prepared the election.
Next, check with your accountant, payroll provider, or attorney. Many businesses file Form 2553 during formation, payroll setup, or tax planning. The owner may not remember the filing, but the preparer may have the signed form, delivery evidence, or the IRS response in the engagement file.
If no one can find a response, call the IRS Business & Specialty Tax Line. Ask whether Form 2553 is pending, accepted, rejected, or missing. A missing election is different from a delayed election. If the IRS never received the form, you may need to refile and explain why the election should still be effective from the intended date. Do not assume that silence means approval.
During the waiting period, keep your records consistent with the intended S election date if you filed on time and expect acceptance. Payroll, distributions, shareholder records, and accounting entries should match the tax treatment you are claiming.
How to Confirm S Corp Status Without Calling
You may be able to confirm S corp status from records you already have. These methods are indirect, but they often answer the practical question before you sit on hold with the IRS.
First, review the federal tax return the business filed. A processed Form 1120-S is strong evidence that the IRS treated the company as an S corporation for that tax year. A Form 1120 points to C corporation treatment. A Schedule C on the owner's Form 1040 usually points to sole proprietorship or disregarded entity treatment, and Form 1065 points to partnership treatment. S corporation shareholders also receive Schedule K-1 from Form 1120-S.
Second, check business tax transcripts. A tax professional with proper authorization may be able to obtain IRS account transcripts that show processed S corporation returns. Transcripts are not the same as a CP261 acceptance notice, but they can be useful when you need to confirm how the IRS has handled the account in past years.
Third, look through formation, tax, and payroll files. Search for Form 2553, CP261, CP264, IRS correspondence, fax confirmations, certified mail receipts, and emails from the person who handled the filing. Small businesses often find the answer in an old tax folder or payroll onboarding file.
Finally, ask your accountant what return was accepted for prior years. If the business has filed and the IRS has accepted Form 1120-S for multiple years, that is a strong sign that the IRS account reflects S corporation treatment. Still, if you need official proof for a transaction, request written IRS confirmation.
Is My LLC an S or C Corp?
An LLC is not automatically an S corporation or a C corporation. LLC is a state-law entity type. S corporation and C corporation are federal tax classifications. That distinction matters because state business records may continue to show your business as an LLC even after the IRS accepts an S corporation election.
If your LLC filed Form 2553 and the IRS accepted it, the LLC may be taxed as an S corporation for federal tax purposes while remaining an LLC under state law. If it did not file and receive an accepted election, it may be taxed under its default classification or another election already made. The label on the Secretary of State website does not answer the federal tax question.
To evaluate what you heard on S corporation tax filing or payroll setup, compare the records. Did the business file Form 2553? Did the IRS send a CP261? Has the company filed Form 1120-S? Do owners receive Schedule K-1 from the S corporation return? Those facts tell you more than the entity name.
The same logic applies to C corporation status. A corporation is generally taxed as a C corporation unless it has an accepted S election. An LLC may also be taxed in different ways depending on its elections and structure. If you are unsure, do not rely on bookkeeping labels, payroll software settings, or state entity search pages. Confirm the IRS tax account and the federal returns actually filed.
Federal S Corp Status vs. State Checks
Federal S corp status and state status are separate questions. The IRS decides whether your federal Form 2553 election is accepted. Your state decides how it registers the entity, whether the entity is in good standing, and how state tax rules apply.
Some states offer online portals that show entity status, annual report status, tax registration status, or state S corporation filing information. Those portals can be useful, especially if you are trying to confirm state compliance. They do not replace the IRS CP261, an IRS verification letter, or the federal tax account.
New Jersey is a common example of why the distinction matters. The state has historically required a separate S corporation election for state purposes and has offered an online S corporation filing service for many elections. In a state like that, a federal S election may not be the whole answer for state tax treatment. Other states may recognize the federal election but still impose state-level taxes, fees, or filing requirements.
If you search for how to check S corp status online California, New Jersey, South Carolina, or another state, read the page carefully. A Secretary of State search usually confirms the entity's public registration. A revenue department page may address state tax status. Neither one is a public IRS lookup. For federal S corp status, use IRS records. For state treatment, check your state's current instructions or ask a tax professional familiar with that state.
Rejected, Late, or Never-Filed Elections
If the IRS says there is no accepted S election, act quickly. The problem can affect payroll, owner distributions, shareholder reporting, and federal returns. Money may have moved as if the business were an S corporation, but the IRS account may still show a different tax classification.
Many S election problems are fixable. IRS late-election relief procedures may allow a business to receive retroactive S corporation treatment if it intended to be an S corporation, acted consistently with that intent, had reasonable cause for missing the deadline, and meets the required conditions. The details matter, especially if prior-year returns were filed, shareholder income was reported, or payroll was already run.
Common rejection or failure points include missing shareholder signatures, missing shareholder consent, filing after the effective-date deadline, using an ineligible shareholder, having more than one class of stock, exceeding the shareholder limit, or making errors in the tax-year section of Form 2553. In community property situations, a spouse's signature may also be relevant.
If an e-filed Form 1120-S is rejected because IRS records do not show an S election, do not keep resubmitting the same return without addressing the election issue. You may need to paper file with the correct support, file or refile Form 2553, request late-election relief, amend prior filings, or coordinate shareholder returns.
If your election was never filed, rejected, or possibly invalid after payroll and distributions already happened, a business or tax attorney can help identify the correct relief path, prepare support for a late election, and coordinate corrected filings. You can post your legal need on UpCounsel's marketplace to connect with experienced attorneys, and responses typically arrive within a day.
Protecting S Corp Status After Confirmation
Once you confirm S corp status, protect it with clean records and basic compliance checks. S corporation tax treatment is valuable, but it depends on continued eligibility and consistent filings.
Keep a permanent digital and paper file with the CP261 or IRS verification letter, the signed Form 2553, proof of mailing or faxing, shareholder consents, stock or ownership records, annual tax returns, Schedule K-1s, payroll records, and major corporate approvals. If the business changes accountants, owners, banks, or buyers, this file prevents repeated status questions.
Review eligibility before ownership changes. S corporations generally must be domestic, have no more than 100 shareholders, have eligible shareholders, and have only one class of stock. Certain trusts and estates may qualify, but partnerships, corporations, and nonresident alien shareholders can create problems. If you are issuing equity, admitting a new owner, or changing distribution rights, check S corporation rules before signing documents.
Coordinate payroll and distributions. S corporation owners who work in the business often need payroll treatment, while distributions are handled separately. Payroll software settings do not create S status, and distributions do not prove S status. The tax election, return filing, and accounting records should all line up.
Set a yearly review before tax season. Confirm the return type, shareholder list, state filings, payroll setup, and retained IRS proof. This is also a good time to ask whether S corporation treatment still fits the business, especially after growth, new investors, or a planned sale.
Frequently Asked Questions
How do I know if my S corp election was accepted?
You know your S corp election was accepted when the IRS confirms Form 2553 approval, usually through a CP261 notice. If that notice is missing, an authorized person can call the IRS and request account confirmation. For practical backup, compare the election effective date with payroll records, shareholder K-1s, and the first accepted Form 1120-S.
Can I check S corp status online for free?
No public IRS tool lets you check S corp status online for free by entering a business name or EIN. Free options still exist, but they are not public lookups: review your IRS notice file, call the IRS business line, or use authorized access to tax records. Avoid paying for sites that only repackage state registration data.
How do I check my Form 2553 status?
Check Form 2553 status by contacting the IRS with the business EIN, legal name, address, and an authorized caller's information. Ask whether the form was received, whether it is pending or accepted, and what effective date is on record. If a preparer filed it, also request the fax confirmation, certified mail receipt, and retained signed copy.
What if I filed Form 1120-S but never received a CP261?
If you filed Form 1120-S but never received a CP261, confirm both the accepted return history and the original election record. A processed S corporation return is helpful evidence, but the acceptance notice or IRS verification letter is cleaner proof. This issue often appears during loan underwriting, due diligence, or a change of accountants.
Can I look up another company's S corp status?
No, you generally cannot look up another company's federal S corp status through a public IRS search. If you are buying, lending to, or investing in a company, request the CP261, an IRS verification letter, recent Form 1120-S filings, Schedule K-1 records, and state tax confirmations through normal due diligence channels.
Does state good standing mean the company is an S corp?
No, state good standing does not mean the company is an S corp for federal tax purposes. Good standing usually means the entity has met state registration or reporting requirements. Federal S corporation treatment depends on IRS acceptance of Form 2553, while state tax treatment depends on that state's separate rules and filings.
