Converting an LLC to a corporation is one of the most common entity restructurings for growing businesses, typically driven by the need to issue stock options, attract investors, or optimize tax treatment (particularly the S-Corp election for payroll tax savings). The good news: when structured correctly, the conversion from LLC to corporation is almost always tax-free under IRC 351. The federal tax treatment depends on the LLC’s current classification (disregarded entity, partnership, or already elected corporate treatment) and the conversion method used. A single-member LLC electing corporate treatment via Form 8832 is deemed to contribute all assets and liabilities to a new corporation in exchange for stock, which qualifies as a tax-free incorporation under IRC 351. A multi-member LLC taxed as a partnership that elects corporate status, or converts under a state formless conversion statute, is treated as contributing all its assets and liabilities to the corporation for stock and then distributing that stock to its members in liquidation. The reverse direction (corporation to LLC) is far more painful: it is treated as a complete liquidation, triggering gain at both the corporate and shareholder levels.

✓Key takeaway

LLC to corporation conversion methods:

Method	Legal Effect	Tax Treatment
Check-the-box election (Form 8832)	LLC remains an LLC under state law; treated as corporation for federal tax only	Tax-free under IRC 351 (deemed asset contribution)
Statutory conversion (state law)	LLC converts to corporation under state statute; same entity, new form	Tax-free under IRC 351 (same deemed contribution)
Formation of new corp + asset transfer	New corporation formed; LLC transfers assets and dissolves	Tax-free under IRC 351 if 80% control test met
S-Corp election only (Form 2553)	LLC elects S-Corp treatment without changing state entity	Tax-free; LLC remains an LLC, taxed as S-Corp

IRC 351 requirements for tax-free treatment:

Requirement	Details
Transfer of property	Cash, equipment, inventory, receivables, goodwill, and other property (NOT services alone)
In exchange for stock	Must receive stock (not debt); other property received is boot
80% control immediately after	Transferor(s) must own at least 80% of total combined voting power AND at least 80% of the total number of shares of all other classes of stock
No excessive boot	Cash or non-stock property received (“boot”) triggers gain up to the boot amount

Single-member LLC conversion (Form 8832 election):

Step	Tax Effect
LLC files Form 8832 electing corporate classification	Deemed to contribute all assets and liabilities to a new corporation
Member receives 100% of stock	100% > 80% control requirement met
Basis of stock	Basis of assets contributed, minus liabilities the corporation assumes
Basis of assets in corporation	Same as basis in the LLC (carryover basis)
Holding period	Tacks (includes time held in LLC)
Gain or loss recognized	$0 (tax-free)

How does the conversion work and what are the traps?

Hypothetical example

Round numbers. A single-member LLC with the following balance sheet wants to convert to a C-Corporation to attract venture capital investors.

LLC balance sheet before conversion:

Asset	Tax Basis	Fair Market Value
Cash	$50,000	$50,000
Equipment	$30,000	$45,000
Inventory	$20,000	$25,000
Accounts receivable	$40,000	$40,000
Goodwill / going concern value	$0	$500,000
Total assets	$140,000	$660,000
Liabilities		$100,000
Net assets (equity)	$40,000	$560,000

Tax-free conversion under IRC 351:

Item	Result
Member contributes all assets ($140,000 basis, $660,000 FMV) and all liabilities ($100,000)
Member receives 100% of corporate stock	Control test met (100% > 80%)
Gain recognized by member	$0
Member’s basis in stock	$140,000 (asset basis) minus $100,000 (liabilities assumed) = $40,000
Corporation’s basis in assets	$140,000 (carryover from LLC)
Corporation’s holding period in assets	Tacks (includes LLC holding period)

The $520,000 of built-in gain ($660,000 FMV minus $140,000 basis) is preserved in two places: (1) the corporation holds assets with $140,000 basis and $660,000 FMV, and (2) the member holds stock with $40,000 basis and $560,000 FMV. The gain is deferred, not eliminated.

Trap #1: Liabilities exceeding basis (IRC 357(c)) If liabilities assumed by the corporation exceed the total basis of assets contributed:

Scenario	Amount
Total basis of assets contributed	$140,000
Liabilities assumed by corporation	$200,000
Excess of liabilities over basis	$60,000
Gain recognized by member	$60,000 (ordinary or capital, depending on asset character)

For a cash-basis business, accounts payable that would be deductible when paid don’t count toward this test (IRC 357(c)(3)), so the trap usually comes from loans and other debt.

Trap #2: Accounts receivable for cash-basis taxpayers

Issue	Effect
Cash-basis LLC has $40,000 in accounts receivable	Tax basis = $0 (not yet included in income)
These are IRC 1221(a)(4) property	Assignment of income doctrine may apply
If corporation collects the receivables	Corporation recognizes ordinary income; member’s stock basis is NOT adjusted

Some advisors recommend collecting receivables before the conversion to avoid this complexity.

Trap #3: Converting with an S-Corp election If the LLC wants to be an S-Corp (not a C-Corp), the process is simpler:

Option	How It Works
File Form 2553 only	LLC keeps its state law status, elects S-Corp treatment. No Form 8832 needed for a domestic LLC (IRS treats the entity election and S election as a single step).
Effective date	Generally effective at the beginning of the tax year (must file by March 15 for calendar year)
Late election relief	Rev. Proc. 2013-30 allows late elections within 3 years and 75 days

Multi-member LLC to corporation:

Step	Tax Treatment
LLC is treated as contributing all assets and liabilities to the corporation for stock, then distributing the stock to members	Tax-free under IRC 351 if the 80% control test is met
Operating agreement terms convert to shareholder agreement	Stock out of line with members’ interests can be treated as a gift or pay between members (Reg. 1.351-1(b)(1))
Partnership K-1s issued through conversion date	Final partnership return filed (short year)
First corporate return filed from conversion date	C-Corp or S-Corp, depending on election

Corporation to LLC (the REVERSE, much more painful):

Event	Tax Consequence
Corporation distributes assets to shareholder(s)	Corporation recognizes gain on ALL appreciated assets (IRC 336)
Shareholders receive liquidating distribution	Shareholders recognize gain on excess of FMV over stock basis (IRC 331)

Using the same numbers in reverse:
Corporation’s gain on asset distribution	$660,000 FMV minus $140,000 basis = $520,000 gain, taxed at 21% = $109,200 corporate tax
Shareholder’s gain on liquidation	$560,000 minus $109,200 corporate tax = $450,800 distributed, minus $40,000 stock basis = $410,800 gain, taxed at 23.8% (20% LTCG + 3.8% NIIT) = $97,770
Total tax on corp-to-LLC conversion	$206,970

This is why the direction matters enormously. LLC to corporation is tax-free. Corporation to LLC triggers double taxation on all built-in gains.

Timing considerations:

Factor	Details
Mid-year conversion	Creates a short final year for an LLC taxed as a partnership and a short first year for the corporation
S-Corp timing	If S-Corp is the goal, coordinate the effective date to be January 1 (avoids short year complications)
State tax implications	Some states impose transfer taxes, franchise taxes, or require new registrations
Employment tax accounts	An LLC that already has an EIN keeps it when it elects corporate classification; a new corporation formed for an asset transfer needs its own EIN
Contracts and licenses	Review whether contracts and professional licenses transfer automatically
Employee benefit plans	Plans may need to be amended or restated for the new entity

When to convert:

Convert to Corporation When	Stay as LLC When
Raising venture capital (VCs require C-Corp)	No outside investors planned
Stock option plans needed (ISOs require corporate form)	Tax flexibility more important than stock options
S-Corp election for payroll tax savings	Profit too low for payroll tax savings to cover the added payroll and return costs
Planning an IPO	Small operation with simple structure
Multiple classes of equity needed	Single owner or simple partnership

What is a single-member LLC and how is it taxed?

A single-member LLC is a legal entity with one owner. The IRS treats it as a disregarded entity by default, meaning it does not file its own return; income and expenses flow directly to Schedule C on the owner’s personal Form 1040. The LLC provides liability protection without adding a separate tax return. Self-employment tax applies to net earnings, same as a sole proprietorship. You can elect S-Corp taxation by filing Form 2553, which keeps the LLC legal structure while changing the tax treatment to require a reasonable salary and allowing the remaining profit as a distribution free of FICA. State treatment varies: some states charge an annual LLC fee or franchise tax regardless of federal tax election.
