LLC Taxed as C-Corp
An LLC can elect to be taxed as a corporation without becoming a state-law corporation. The election can create a 21% corporate-level tax, a second tax layer on dividends, different filing duties and potentially significant consequences when the classification later changes.
What does “LLC taxed as a C-Corp” mean?
An LLC taxed as a C-Corp remains an LLC under state law but elects to be classified as an association taxable as a corporation for federal income-tax purposes. The entity generally files Form 1120 and computes federal corporate income tax at 21%. If after-tax earnings are later distributed as taxable dividends, the owners can face a second tax layer. Form 8832 is therefore a tax-classification decision—not a substitute for forming a corporation when corporate stock, investor rights or state-law corporate governance are actually required.
What the C-Corp Election Changes—and What It Does Not
A domestic eligible LLC can elect corporate classification for federal income-tax purposes. A single-member LLC that otherwise would be disregarded, or a multi-member LLC that otherwise would generally be taxed as a partnership, can use Form 8832 to elect classification as an association taxable as a corporation.
The legal entity does not automatically become a corporation. Your state-law LLC generally remains governed by its LLC statute and operating agreement. Federal tax classification and state-law entity form are separate layers.
State-law layer
The business remains an LLC unless you separately complete a state-law conversion or incorporation. Membership rights, governance and liability rules continue to come from state law and the operating agreement.
Federal tax layer
The IRS treats the eligible entity as an association taxable as a corporation. The entity generally files Form 1120 rather than Schedule C or Form 1065 for federal income-tax reporting.
How C-Corp Taxation Works for an LLC
The corporate tax layer is straightforward in concept but not necessarily cheap in total. A corporation generally computes its own taxable income and applies the federal corporate tax rate. The current Form 1120 instructions direct corporations to multiply taxable income by 21%.
What happens after that depends on how value leaves the corporation. Wages to an owner-employee can be deductible to the corporation if properly treated and reasonable, while dividends are generally not deductible. A dividend can therefore create the classic second tax layer: corporate income tax first, shareholder-level tax later.
Do not compare 21% directly with your personal marginal rate. A valid comparison must consider compensation, payroll taxes, dividends, retained earnings, state corporate taxes, owner-level taxes, deductions, credits and the timing of distributions. A simple “21% is lower than 37%” comparison is incomplete.
When C-Corp Tax Treatment May Be Worth Modeling
C-Corp treatment is not inherently “better” or “worse.” It is a different tax regime. The strongest cases are situations where the corporate layer serves a real business objective rather than being chosen solely because 21% looks lower than an owner's marginal rate.
Long-term business reinvestment
If significant profits genuinely remain in the business for expansion, hiring, equipment, research or other bona fide needs, corporate taxation may deserve modeling. Later extraction still matters, and unreasonable accumulations can create additional tax concerns.
Corporate-tax planning with advisers
Some benefit, compensation, international, financing or owner situations can make corporate treatment relevant. These require fact-specific modeling rather than a generic online threshold.
Planned corporate conversion or financing
If future investors require a corporation, compare a direct state-law conversion/incorporation with remaining an LLC and merely electing corporate tax treatment. Form 8832 alone does not create preferred stock or a corporate charter.
Exit planning where §1202 may matter
Qualified Small Business Stock planning can be valuable, but §1202 requires qualifying stock in a domestic C corporation and several additional tests. Do not assume LLC membership interests automatically satisfy those stock requirements.
QSBS: Why Form 8832 Alone Is Not a Safe Shortcut
Section 1202 can exclude eligible gain on qualifying small-business stock, but the statute and current IRS guidance start with a threshold requirement: the asset must be stock in a C corporation, generally acquired at original issue, and the issuing corporation must satisfy the gross-assets and active-business rules.
Current IRS guidance reflects a $75 million gross-assets threshold for stock issued after July 4, 2025, compared with $50 million for stock issued on or before that date. The 2025 law also changed holding-period and exclusion rules for certain newly issued stock.
If QSBS is a core exit strategy, get tax and corporate counsel before relying on a check-the-box election. An LLC taxed as a corporation is not automatically a state-law corporation with issued shares of corporate stock. The legal form of the equity, timing of issuance/conversion, basis, active-business tests and transaction steps should be designed before the event—not reconstructed after an exit.
How Form 8832 Works
Form 8832 is the IRS entity-classification election used by eligible entities that want a classification different from the applicable default. For a domestic LLC electing C-Corp tax treatment, the key selection is classification as an association taxable as a corporation.
Confirm the election is the right transaction
Identify the LLC's current federal classification and model the deemed tax consequences of changing it. A partnership-to-corporation election, for example, is treated as a deemed asset-and-liability contribution to the association followed by liquidation of the partnership.
Use the LLC's EIN
An existing entity that already has its own EIN generally continues using it. If the eligible entity has no EIN, obtain one before Form 8832 is filed.
Choose the effective date carefully
The general window is no more than 75 days before filing and no more than 12 months after filing. Late-election relief may be available when its requirements are met.
Complete the classification and consent
The form can be signed by each owner at filing or by an authorized officer, manager or member. Additional prior owners may need to sign when a retroactive effective date is used.
File using the current IRS instructions
Service-center addresses and procedural details can change. Use the current Form 8832 instructions rather than hard-coding an old mailing address into your compliance process.
Keep the IRS determination and file consistently
Retain the acceptance/nonacceptance notice, attach copies where the current instructions require, and make sure the entity and owners file consistently with the effective classification.
The 60-Month Rule Is Real—but Not Universal
The IRS states that once an LLC elects to change its classification, it generally cannot elect another classification change during the 60 months after the effective date. That is a major planning constraint—but the old shorthand “every Form 8832 election locks you in for five years” is not precise enough.
Important exception: an election made by a newly formed eligible entity that is effective on the date of formation is generally not treated as a classification change for this 60-month limitation. The regulations and Form 8832 instructions also contain other exception mechanics.
Changing away from corporate classification can also create deemed tax transactions. An association electing partnership classification, for example, is generally treated as distributing its assets and liabilities to shareholders in liquidation and then contributing them to a new partnership. Appreciated assets can therefore make a later switch economically significant.
What Changes After Corporate Classification
A calendar-year corporation generally files Form 1120 by the 15th day of the fourth month after year-end. Corporate estimated-tax installments are generally due by the 15th day of the 4th, 6th, 9th and 12th months of the corporation's tax year when required.
Default LLC vs S-Corp vs C-Corp Tax Treatment
| Issue | Default LLC taxation | S-Corp election | C-Corp election |
|---|---|---|---|
| State-law entity | LLC | LLC unless separately converted | LLC unless separately converted |
| Federal tax return | Depends on owner count/classification | Form 1120-S | Form 1120 |
| Entity-level federal income tax | Generally pass-through | Generally pass-through | Generally 21% of taxable income |
| Owner working in business | Rules depend on classification | Reasonable compensation rules for shareholder-employees | Corporate employee-compensation rules apply when owner is an employee |
| Distributions | Generally not a second corporate dividend layer | Generally pass-through distribution rules | Dividends can create a second tax layer |
| QBI / §199A | May be available when requirements are met | May apply to qualifying pass-through income | Not available to C-corporation income itself |
| Tax-classification flexibility | Can elect if eligible | Eligibility and termination rules apply | Subsequent change can be constrained by 60-month rule |
| Best question | How are owners taxed now? | Does S election fit compensation and ownership? | Why do we need the corporate tax layer? |

You need most profits personally each year
Regular dividend extraction can create a second tax layer. Model compensation and distributions rather than assuming 21% represents the total burden.
You want pass-through treatment of losses
Corporate losses generally remain at the corporation rather than flowing directly to owners in the same manner as qualifying pass-through losses.
You may change classification again soon
The 60-month limitation and deemed transaction rules can make another change harder or taxable. Do not make a speculative election.
Your only reason is “21% is lower”
That comparison ignores owner-level taxation, payroll, state tax, deductions and future distributions. Start with a complete tax model instead.

Primary Sources & Verification
This guide separates the LLC's state-law entity form from its federal tax classification and focuses on the decisions that should be verified before filing Form 8832. Corporate tax, QSBS, compensation, state tax and later classification changes can be highly fact-specific, so primary IRS guidance should be rechecked at the time of filing.
