Does an S Corp Have an Operating Agreement or Bylaws?

Whether an S corporation has an operating agreement or bylaws depends on how the business was formed at the state level. An LLC that elects S corp tax treatment keeps its operating agreement. A corporation that elects S corp tax treatment uses bylaws. “S corporation” is a federal tax status, not a state-level entity type, so the governing document follows the underlying entity, not the tax election.

S Corp Status Is a Tax Election, Not an Entity Type

No state lets you file paperwork to form an S corporation directly. You first create either a corporation or an LLC under state law, then separately ask the IRS to tax that entity as an S corporation by filing Form 2553.¹ The IRS approves the election only if the entity qualifies as a “small business corporation”: a domestic entity with no more than 100 shareholders, only individuals (plus certain trusts and estates) as shareholders, no nonresident alien shareholders, and only one class of stock.²

Once the election takes effect, profits and losses pass through to the owners’ personal returns instead of being taxed at the entity level first.³ Nothing about that tax change alters the internal organization of the business. Your state-level entity still controls which governing document applies.

LLCs That Elect S Corp Status Keep the Operating Agreement

If your LLC elected S corp treatment, the operating agreement remains the primary governance document. The election did not convert the LLC into a corporation. You still have members, and your operating agreement still sets out who manages the company, how decisions get made, and how money moves to owners.⁴

Not every state requires LLCs to have a written operating agreement, but running without one means state default rules fill the gaps. Those defaults are generic and almost certainly do not account for S corp compliance requirements. Whether your state mandates the document or not, operating an S-elected LLC without one is a risk.⁴

Corporations That Elect S Corp Status Use Bylaws

If you formed a traditional corporation and then elected S corp status, your governing document is a set of corporate bylaws. Bylaws cover the mechanics of running a corporation: how shareholder meetings are called, how directors are elected, what officers do, and how stock is issued or transferred. The S election changes the tax treatment but leaves the corporate governance structure in place.

Corporations also carry more built-in formalities than LLCs. You need a board of directors, annual meetings, and documented resolutions for major decisions. Letting those formalities slide can weaken limited liability protection, since courts look at whether owners respected the separation between themselves and the business.

The One-Class-of-Stock Trap in Operating Agreements

This is where the operating-agreement-versus-bylaws question turns into a real compliance issue, and it catches owners who file Form 2553 and leave the existing operating agreement untouched. Federal regulations require that all shares of an S corporation carry identical rights to distributions and liquidation proceeds.⁵ If your operating agreement gives some members priority distributions, or allocates liquidation proceeds based on capital account balances rather than ownership percentages, the IRS can treat the company as having two classes of stock and disqualify it from S corp status entirely.²

The IRS evaluates this based on “governing provisions,” a term that includes articles of incorporation, bylaws, operating agreements, applicable state law, and any binding agreements about distributions or liquidation proceeds.⁵ The mere existence of a conflicting provision can invalidate the election, even if you never actually followed that provision and always distributed money proportionally. The IRS looks at what the document allows, not just what you did.

Provisions that commonly create problems include priority distribution waterfalls that give certain members first access to profits, capital-account-based liquidation language that directs assets out based on capital balances rather than ownership percentages, and special allocation provisions that split income, losses, or distributions in ratios other than ownership. These clauses are common in LLC operating agreements drafted for entities taxed as partnerships, where flexible allocation is a core advantage. Carrying that partnership-style language into an S-elected LLC is a compliance hazard sitting inside your own governing document.

Updating an Operating Agreement After Electing S Corp Status

If your LLC recently elected S corp status, or elected it years ago without revising the operating agreement, review the document. At minimum, the agreement should:

Require all distributions to go out based on ownership percentage, with identical timing and amounts per share.
Strip out partnership-style language that allocates profits, losses, or credits in ratios other than ownership percentages.
Restrict transfers so no member can assign their interest to anyone ineligible to hold S corp shares under federal law.
State that the LLC and its members intend to comply with all S corporation requirements and that no action may be taken that would jeopardize the election.

Revenue Procedure 2022-19 gives businesses with non-identical governing provisions a path to self-correct without requesting a private letter ruling, but only under specific conditions. The company must not have actually made disproportionate distributions, must have timely filed Form 1120-S for all affected years, and must fix the offending provisions before the IRS discovers them. If those conditions are met, you can amend the operating agreement, prepare internal correction statements, and move on. If the IRS finds the problem first, or if disproportionate distributions actually went out, the self-correction path closes and restoring S corp status becomes far more expensive.

Transfer Restrictions That Protect the Election

A single share transferred to an ineligible owner terminates the S corp election immediately. Partnerships, other corporations, and nonresident aliens cannot hold S corp shares.² If a member sells, gifts, or otherwise transfers their interest to any prohibited holder, the entity stops qualifying as a small business corporation on the date of the transfer.⁶

After a termination, the company cannot re-elect S corp status for five years.⁶ The IRS can waive that waiting period if the termination was “inadvertent” and the company quickly corrects the problem, but getting that relief requires a private letter ruling, which costs tens of thousands of dollars in IRS fees alone.

Your operating agreement or bylaws should include a transfer restriction that prohibits any owner from selling, gifting, or assigning their interest to a person or entity that would disqualify the company from S corp status. Many agreements also add a right of first refusal, letting existing owners buy out a departing member before any outside transfer can go through. Without these provisions, the election depends on every owner understanding the eligibility rules, and one family gift to the wrong trust or a divorce settlement transferring shares to a nonresident spouse can end the election overnight.

What a Governing Document Typically Costs

Attorney fees for drafting or reviewing an operating agreement or bylaws for a small business generally range from about $500 to $1,700, depending on the complexity of the ownership structure and the local market. A single-owner LLC with a straightforward S corp election sits at the low end. Multi-member LLCs with buyout provisions, vesting schedules, and detailed management structures cost more. The expense is modest against the cost of losing an S corp election retroactively or resolving an owner dispute with no written agreement in place.
