If you’ve been an entrepreneur long enough, you probably know that special kind of dread that arrives with tax season.

You’ve worked your tail off all year creating something out of nothing, signing checks before you can cash your own, betting on yourself again and again. Then it’s time to pay the bill. The IRS bill.

For most of my career, I just accepted it as part of the game. I told myself, “This is what success looks like.” Pay the tax, move on.

But a few years ago, I realized I had been doing something incredibly stupid for more than two decades. I was overpaying my taxes.

The rule I knew about and ignored

More than 20 years ago, someone told me about something called the Augusta Rule. It’s a small, oddly-named provision buried deep in the tax code — Section 280A(g), for those who care about numbers.

In simple terms, it allows you to rent out your personal home to your business for up to 14 days each year. Your business can deduct the rent, and you don’t have to pay tax on that income. It’s 100% legitimate and IRS-approved.

When I first heard about it, I thought, that can’t be real. It sounded like one of those too-good-to-be-true things people talk about at conferences. I mentioned it to my accounting team, they nodded politely and that was the end of it.

Years went by. Then decades.

At some point, I stopped even thinking about it until one day I stumbled across it again, while helping a friend with his tax planning. I did the math on what I’d missed, and my stomach turned.

If I’d implemented it properly, I could have saved hundreds of thousands of dollars over those 20-plus years. Money that could have been invested, compounded and turned into over a million by now.

It was one of those moments that make you stop, stare out the window and realize you’ve been asleep at the wheel in a part of your own business.

How I met someone who made me rethink everything

Not long after that wake-up call, I met Nethaniel Ealy, an entrepreneur who had lived a similar story but with a different ending.

He had built a successful construction company, worked brutal hours and finally got to a point where he thought he was winning. Then came the tax bill.

One year, sitting in his CPA’s office, he realized he was paying more in taxes than he was taking home to his family. He asked his accountant if there was anything they were missing. The accountant shrugged.

That was his breaking point. He started reading the tax code himself. That’s when he discovered the Augusta Rule and began implementing it properly. For him, it was about understanding it.

He told me how he’d always been the guy who could fix a broken process, whether it was a construction project or a business system. Taxes, he realized, were just another system. One that too many of us treat like a black box.

His story hit home. Because even though our industries were different, the feeling was the same. There was a sense that we were building something real, but losing ground because we didn’t understand the hidden rules of the game.

What this experience really taught me

When I look back now, the real mistake wasn’t that I missed a tax rule. It was that I stopped asking questions.

As entrepreneurs, we spend so much time in motion: launching products, hiring teams, chasing growth. We forget to slow down and look under the hood. We assume that because we’ve hired smart professionals, they’re automatically catching every opportunity.

But here’s the truth: Even the best advisors won’t care about your money the way you do. It’s your responsibility to stay curious.

I used to think that “understanding taxes” meant trying to memorize obscure deductions or outsmart the IRS. That’s not it. It’s about awareness. It’s about knowing how your business interacts with the financial system you operate in.

The Augusta Rule is just one example. The bigger principle is this:

If you don’t understand the rules of the system you’re playing in, you’ll always be at its mercy.

That realization changed how I approach everything.

Now, when I meet with my accounting team, I don’t just ask, “What do I owe?” I ask, “What are we missing? What assumptions are we making that might be wrong?”

It’s about closing the gap between what’s possible and what’s habitual.

The entrepreneur’s blind spot

We love to talk about innovation and growth; now, let’s discuss preservation.

I can tell you the latest growth hack, the best AI tools or how to automate a sales funnel, but most of us glaze over when the topic turns to tax structure, cash flow discipline or compounding.

Looking back, my biggest financial mistake wasn’t a bad investment or a failed launch. It was passive neglect. It was assuming “someone else is handling that.”

We do that with taxes, with health, with relationships until something painful forces us to pay attention.

A different kind of freedom

The irony is that paying attention to these details that save you money can give you freedom.

Freedom of time, because you stop wasting energy on unnecessary work just to cover what you overpaid. Freedom of focus, because you’re not constantly scrambling to make up for missed opportunities. And freedom of choice, because you finally understand the systems that shape your success.

When I finally understood how the Augusta Rule worked, and all the other small, boring, technical things I’d ignored for years, I felt something I hadn’t felt in a long time: calm.

It wasn’t about the money anymore. It was about control.

The bottom line

Here’s what I know now: You can’t delegate understanding.

You can hire great people, automate processes and build incredible teams. There are parts of your business, especially when it comes to money, that you have to own.

So if you take anything from my story, let it be this: Don’t assume that because something sounds “boring” or “technical,” it isn’t worth your time. The difference between surviving and thriving often comes down to the details we overlook.

The Augusta Rule happened to be my wake-up call. Yours might be something entirely different.

Either way, don’t wait 21 years to start paying attention.
