Most business owners think of their operating agreement as a legal formality. It was something you signed at the business formation and filed away. Maybe you formed as a sole proprietor years ago and never even created an operating agreement document when you added a partner or shareholder. That’s a mistake. For tax purposes, your operating agreement is arguably the most consequential document your business has. For business valuation and sale, it serves as the primary control.
For ordinary taxes, it matters more than most people realize. It controls how profits and losses are taxed. In a multi-member LLC, the IRS requires that special allocations of income and loss have what’s called “substantial economic effect.” Giving one partner a larger share of depreciation or deductions, for example, requires specific provisions in the operating agreement: capital account maintenance, liquidation rules, and sometimes deficit restoration obligations. Without those mechanics written in, years later the IRS can simply disregard your allocations and reallocate income however the rules dictate. Many LLC agreements are silent on all of this.
It can silently undermine your S corporation election. An S corp can only have one class of stock. Side agreements, informal shareholder arrangements, or operating agreement language that creates disproportionate distribution rights can inadvertently blow that election — triggering a hidden tax bill and reclassification you never saw coming. Improperly structured C corporations carry their own hazards — particularly at sale, where double taxation can eliminate much of what the seller expected to pocket.
This affects what your business is worth. When a business interest is valued for estate planning, gifting, or a sale, other parties look directly at the operating agreement. Transfer restrictions, consent requirements, and discretionary distribution clauses reduce the value of minority interests — which can be a planning advantage or a liability, depending on your situation. Distribution waterfalls that give the managing member unchecked discretion introduce uncertainty that buyers, appraisers, and taxing authorities will price accordingly.
I’ve increasingly seen this problem kill a deal. Unanimous consent requirements, poorly drafted rights of first refusal, and missing drag-along provisions are among the most common reasons small business sales fall apart or stall. If a dissenting member can block a transaction, that’s not a governance issue — it’s a valuation issue. It’s possibly a malpractice issue.
The operating agreement most small businesses are working with was drafted years ago, probably by a general-practice attorney, for a few hundred dollars, and has never been updated. The tax exposure and salability friction built into that document is often the biggest unaddressed risk in the business.
If you’re planning a sale, doing estate planning, or simply haven’t looked at your operating agreement in a few years, that’s where the conversation should start. Have your business operating agreement reviewed now.
