LLC Operating Agreement: Why You Need One (Even Solo)

What an LLC operating agreement is, what it should include, and why even single-member LLCs should have one.

An operating agreement is the internal rulebook for your LLC. Only a handful of states legally require one — but every LLC should have one.

Why it matters

Banks often ask for it before opening a business account. It reinforces your liability protection by proving the LLC is a separate entity. And it prevents disputes between members down the line.

What it should include

Ownership percentages, capital contributions, profit and loss distribution, voting rights, management structure (member-managed vs manager-managed), and what happens if a member dies or leaves.

Single-member operating agreements

Even if you're solo, having one shows the IRS and courts that your LLC is a real, separate entity — which is what protects your personal assets.

Do you need a lawyer?

For simple LLCs, a well-drafted template works. Use a lawyer if you have unusual profit splits, vesting schedules, or outside investors.

The takeaway

It's a one-time document that protects your business for its entire life. Don't skip it.
