An LLC can be taxed as a corporation by filing an election with the IRS: Form 8832 to be treated as a C-corporation, or Form 2553 to be treated as an S-corporation. The election changes how profits are taxed, how owners pay themselves, which benefits the business can deduct, and how easily the structure can be unwound later. The underlying legal entity stays an LLC under state law; only the federal tax classification changes.
Why an Election Is Needed
Without an election, the IRS classifies a single-member LLC as a disregarded entity and a multi-member LLC as a partnership. In both cases, the business itself pays no federal income tax and all profits flow to the owners’ personal returns.1eCFR. 26 CFR 301.7701-3 – Classification of Certain Business Entities The federal check-the-box regulations let an eligible LLC override that default and be taxed as a corporation instead.2Internal Revenue Service. About Form 8832, Entity Classification Election
C-Corporation or S-Corporation
The two corporate options work very differently. A C-corporation election subjects the LLC to a flat 21% federal corporate income tax at the entity level.3Office of the Law Revision Counsel. 26 USC 11 – Tax Imposed Profits are taxed once at the corporation and again when distributed as dividends to owners. In exchange, C-corp status opens up fringe benefit deductions and a capital gains exclusion that other structures don’t offer.
An S-corporation election keeps pass-through taxation but lets owner-employees split their income between salary (subject to payroll taxes) and distributions (not subject to payroll taxes). The result is often a lower total tax bill than a default LLC would produce, at the cost of stricter eligibility rules and more compliance work.
S-Corporation Eligibility
Any domestic LLC can elect C-corporation status. S-corporation status is gated by continuous eligibility requirements that the LLC must meet on the effective date and every day afterward:4Internal Revenue Service. S Corporations
- No more than 100 owners.
- Owners must be U.S. citizens or resident aliens who are individuals, or certain trusts and estates. Partnerships, corporations, and nonresident aliens cannot hold an interest.
- Only one class of stock. The operating agreement cannot create different economic rights among owners, such as preferred returns or disproportionate profit allocations. Distribution and liquidation rights must be identical across ownership interests.
Violating any of these requirements after the election takes effect automatically terminates S-corporation status. This is where LLCs commonly trip up. Operating agreements drafted for a standard multi-member LLC often include priority distributions or special allocations that would disqualify the entity. Review and amend the operating agreement before filing.
How to File the Election
Form 8832 for C-Corporation Treatment
File Form 8832 with the IRS. The form asks for the LLC’s legal name as it appears on its articles of organization, its EIN, its formation date, and the state of organization. Every member must sign to consent, unless the operating agreement authorizes a single officer to act for the entity.5Internal Revenue Service. Form 8832 – Entity Classification Election
The effective date you choose cannot be more than 75 days before the filing date or more than 12 months after it. A date outside that window defaults to the filing date. The IRS confirms acceptance with a CP277 notice, which belongs in your permanent records.6Internal Revenue Service. Understanding Your CP277 Notice
Form 2553 for S-Corporation Treatment
File Form 2553, which collects more detailed owner information than Form 8832: each owner’s name, address, Social Security number, ownership percentage, and the date they acquired their interest. Every person who was an owner at any point during the tax year must sign the consent section.7Internal Revenue Service. Instructions for Form 2553
The deadline is tight. For the election to take effect in the current tax year, Form 2553 must be filed no more than two months and 15 days after the start of that tax year. For a calendar-year LLC, that’s March 15. You can also file any time during the preceding tax year.8Internal Revenue Service. Instructions for Form 2553 Miss the deadline and the election generally slips to the next tax year unless you qualify for late-election relief.
The IRS confirms acceptance with a CP261 notice.9Internal Revenue Service. Understanding Your CP261 Notice Processing for either form typically takes 45 to 60 days. If nothing arrives within eight weeks, contact the IRS. Mail with tracking so you can prove the filing date if a dispute comes up.
The Conversion Itself Is a Taxable Event
Changing classification is not a paperwork switch. The IRS treats it as a series of deemed transactions, as if the LLC’s assets physically moved into a new corporate entity.
A multi-member LLC converting from partnership to corporation is treated as if the partnership contributed all its assets and liabilities to a new corporation in exchange for stock and then liquidated by distributing that stock to the partners. A single-member LLC converting from disregarded entity to corporation is treated as if the sole owner contributed the LLC’s assets and liabilities to a corporation in exchange for stock.10Internal Revenue Service. Limited Liability Company – Possible Repercussions
These deemed contributions are generally tax-free under IRC Section 351, which provides that no gain or loss is recognized when property is transferred to a corporation in exchange for stock, as long as the transferors control at least 80% of the corporation immediately after the exchange.11Office of the Law Revision Counsel. 26 USC 351 – Transfer to Corporation Controlled by Transferor Because all the LLC members are contributing simultaneously and receiving all the corporation’s stock, that threshold is almost always met. But if the LLC’s liabilities exceed the tax basis of its assets, or certain debt-related issues exist, the conversion can trigger gain. Run the numbers with a tax professional before filing.
Living With C-Corporation Taxation
After the election takes effect, the LLC files Form 1120 and pays 21% federal income tax on taxable income.12Internal Revenue Service. Instructions for Form 1120 Owners report business income only when they receive a salary or a dividend. Dividends are taxed again on the owner’s personal return. That’s the double tax. Several C-corp features can offset it.
Fringe Benefits
C-corporation owner-employees can receive employer-provided fringe benefits on the same tax-free basis as any other employee. The corporation deducts the cost, and the owner-employee excludes it from income. Health insurance premiums, group-term life insurance up to $50,000 in coverage, accident and health plan benefits, adoption assistance, and cafeteria plan participation all qualify. S-corporations cannot offer these same tax-free benefits to any owner holding more than 2% of the company.13Internal Revenue Service. Publication 15-B (2026), Employers Tax Guide to Fringe Benefits
Qualified Small Business Stock
Under IRC Section 1202, capital gains on the sale of qualified small business stock held for at least five years can be excluded from federal income tax. The per-taxpayer exclusion limit is the greater of $10 million or ten times the adjusted basis in the stock. For stock acquired after July 4, 2025, the corporation’s maximum gross assets threshold is $75 million (up from $50 million for stock issued earlier).14Office of the Law Revision Counsel. 26 USC 1202 – Partial Exclusion for Gain From Certain Small Business Stock Only C-corporations qualify. For founders building toward a sale, this exclusion can outweigh years of pass-through savings.
Accumulated Earnings Tax
C-corporations that retain profits beyond what the business needs face an additional 20% tax on the excess. The IRS treats accumulations up to $250,000 as presumptively reasonable for most businesses. For personal service corporations in fields like law, accounting, health, engineering, and consulting, the threshold drops to $150,000.15Internal Revenue Service. Publication 542, Corporations If you plan to retain significant earnings, document the specific business reasons in writing.
Living With S-Corporation Taxation
An S-corporation files Form 1120-S but pays no federal income tax at the entity level. Income, losses, deductions, and credits flow through to each owner’s personal return on Schedule K-1.16Internal Revenue Service. About Form 1120-S, US Income Tax Return for an S Corporation You owe tax on your share of profits whether or not cash was actually distributed, so the business needs a distribution policy that gives owners enough to cover their tax bill.
Salary and Distributions
The core financial benefit of S-corp taxation is splitting income between salary and distributions. As an owner-employee, you must pay yourself a salary subject to Social Security tax (6.2% each for employer and employee, on earnings up to $184,500 in 2026) and Medicare tax (1.45% each, with no cap).17Social Security Administration. Contribution and Benefit Base The combined employer-and-employee share is 15.3% on wages up to the Social Security wage base. Profits distributed above your salary are not subject to those employment taxes.
The catch: the IRS requires salary to be “reasonable compensation” for the work you actually perform, judged against training, responsibilities, hours committed, and what comparable businesses pay for similar roles. If the IRS finds your salary was unreasonably low, it can reclassify distributions as wages and assess back employment taxes, penalties, and interest. This is one of the most audited S-corp issues, and the cases that go to court usually turn on whether the owner documented how they set the salary. Keep records of industry compensation surveys or a board resolution explaining the methodology.
No Self-Employment Tax on K-1 Income
Your share of S-corporation income that passes through on Schedule K-1 is not self-employment income and is not subject to self-employment tax.18Internal Revenue Service. Instructions for Schedule K-1 (Form 1120-S) That’s the structural difference from a default LLC, where net earnings from the business generally flow into the self-employment tax calculation. Make quarterly estimated tax payments to cover the income tax on your K-1 allocations, since no withholding occurs on distributions.
Missed the Deadline
Missing a filing deadline doesn’t necessarily end the election.
For a late S-corporation election, Revenue Procedure 2013-30 provides relief. The entity must have intended S-corporation classification as of the intended effective date, must have had reasonable cause for filing late, and must request relief within three years and 75 days of the intended effective date. The failure must have been solely because the form wasn’t filed on time.19Internal Revenue Service. Revenue Procedure 2013-30 To request it, file Form 2553 with “FILED PURSUANT TO REV. PROC. 2013-30” at the top, attach a signed reasonable-cause statement, and have every person who was an owner during the period between the intended effective date and the filing date sign and confirm they reported income consistently with S-corporation treatment.
For a late C-corporation election under Form 8832, Revenue Procedure 2009-41 applies. The requirements parallel the S-corp process: intended classification from the start, all tax returns filed consistently with that classification, reasonable cause for the delay, and a request submitted within three years and 75 days of the intended effective date. Complete Part II of Form 8832 with the explanation, signed under penalties of perjury.5Internal Revenue Service. Form 8832 – Entity Classification Election
Getting Out of Corporate Status
Reversing an election is harder than making one.
To voluntarily revoke an S-corporation election, owners holding more than half of the ownership interests on the day of revocation must consent in writing.20Office of the Law Revision Counsel. 26 USC 1362 – Election; Revocation; Termination A revocation filed by the 15th day of the third month of the tax year (March 15 for calendar-year entities) takes effect for the current year. Later than that and it applies to the next tax year unless a future effective date is specified. S-corporation status also terminates automatically if the LLC stops meeting the eligibility rules, such as picking up a 101st owner or an ineligible shareholder. Once an S-election is revoked or terminated, the entity generally cannot re-elect S-corporation status for five tax years without IRS consent, though the IRS may waive the wait if more than 50% of ownership has changed since the termination or if the termination was inadvertent and corrected promptly.
An LLC taxed as a C-corporation can file a new Form 8832 to change classification back, but the check-the-box regulations generally prevent more than one classification change within a 60-month period. Switching back and forth is not an option, so time any reclassification carefully.
The Built-In Gains Tax
If an LLC was taxed as a C-corporation and later elects S-corporation status, any appreciation in asset values that existed on the conversion date is subject to the built-in gains tax for five years after the switch. During that recognition period, if the S-corporation sells an appreciated asset, the built-in gain is taxed at the highest corporate rate of 21%.21Office of the Law Revision Counsel. 26 USC 1374 – Tax Imposed on Certain Built-In Gains That’s on top of the pass-through income tax owners already owe on the gain. Get an appraisal at the conversion date and avoid selling appreciated assets during the five-year window when possible.
State Taxes Follow Their Own Rules
A federal election doesn’t decide how your state taxes the LLC. Most states follow the federal classification, but several impose their own entity-level taxes regardless. Some charge franchise taxes or minimum annual fees that apply to all LLCs. A handful impose entity-level income taxes even on S-corporations, which can partially cancel the pass-through benefit. Check your state’s rules before assuming a federal election produces the same result at the state level.
