At some point, someone told you to set up an LLC. Maybe it was your attorney. Maybe it was a friend who'd been through a lawsuit. Maybe you just read enough online to know that protecting your assets was important.

So you formed the entity. Maybe a few of them. And now you've got a structure in place that keeps your personal assets separate from your business liabilities.

That's good. You should have that protection.

But here's what most business owners don't realize: the structure that protects your assets isn't necessarily the structure that minimizes your taxes. Those are two different problems. And if no one's solving the second one, you might be overpaying every year without knowing it.

How entity structure affects your taxes.

Every entity type has different tax treatment. A single-member LLC is "disregarded" by the IRS, which means all the income flows directly to your personal return. A multi-member LLC is taxed as a partnership. An S-corp lets you split income between salary and distributions. A C-corp is taxed at the corporate level before anything reaches you personally.

None of these are inherently better or worse. It depends on your situation: how much income you have, what your other tax obligations look like, and what you're trying to accomplish.

The problem is that most business owners pick an entity type once and never revisit it. They set up an LLC because that's what everyone does, and they never ask whether a different structure might save them money.

Common mistakes we see.

Taking the default election. When you form an LLC, the IRS assigns a default tax treatment based on how many members you have. But you're not stuck with the default. You can elect to be taxed as an S-corp or even a C-corp if that makes sense for your situation. Many business owners don't know this is an option, so they never consider it.

Too many separate entities with no coordination. If you've got five LLCs that all operate independently, you might be missing opportunities to shift income, share expenses, or structure things more efficiently. Sometimes a holding company makes sense. Sometimes consolidating entities makes sense. But if no one's looking at the big picture, you're just managing complexity without getting any benefit from it.

Operating agreements that ignore taxes. Your operating agreement governs how profits and losses are allocated among members. That allocation has real tax consequences. If your agreement was drafted with only legal considerations in mind, it might be creating tax outcomes that aren't in your favor.

Keeping a structure that made sense five years ago. Your business has probably changed since you first set things up. Revenue is different. Your goals are different. Maybe you've added partners or properties or new lines of business. The structure that fit your situation back then might not be the right fit now.

The difference between legal advice and tax advice.

Your attorney's job is to protect you from liability. They're thinking about worst-case scenarios: lawsuits, creditors, disputes. That's valuable, and you should listen to them.

But most attorneys aren't also CPAs. They're not looking at your entity structure through a tax lens. They're solving for risk, not for tax efficiency.

This means the advice you got when you formed your entities was probably good legal advice. But it might not have been complete advice. If no one's looked at your structure from a tax perspective, there could be opportunities you're missing.

When to revisit your structure.

You don't need to rethink your entities every year. But there are certain triggers that should prompt a review:

You've added new entities or properties since your last review. Your income has grown significantly. You're considering selling a business or property. You've brought on partners or investors. You're operating in multiple states. Your personal tax situation has changed (marriage, divorce, retirement planning).

Any of these can shift the calculus on what structure makes the most sense.

What a review looks like.

A good entity structure review starts with understanding what you have and why you have it. Then it asks: given your current situation and goals, is this still the right setup?

Sometimes the answer is yes, and you've got peace of mind. Sometimes the answer is no, and there's work to do. Either way, you're making decisions with full information instead of just hoping the structure you set up years ago is still serving you.

The goal isn't to make things more complicated. It's to make sure your structure is actually working for you, not just protecting you.
