Mike Tyson earned a reported nine figures and still filed for bankruptcy owing tens of millions. The thing he was missing was not income

In August 2003, one of the highest-earning athletes of his generation walked into a bankruptcy court in Manhattan.

He was not a cautionary tale about a bad contract. The contracts had been enormous.

Over roughly two decades, ABC News reported at the time of the filing, Mike Tyson had taken in something on the order of $400 million from boxing. The same reporting on his Chapter 11 filing described obligations of more than $27 million — the figure most commonly repeated since is roughly $23 million — and a spending rate of about $400,000 a month.

Al Jazeera's account of the filing put it more bluntly: some $300 million gone on cars, jewellery and miscellanea.

Nine figures in. Tens of millions owed on the way out.

You are not a heavyweight champion, but the money behaves the same way

Strip away the tigers and the Bentleys and what is left is an ordinary self-employment problem at an extraordinary scale.

The income was gross, not net. It was irregular — a fight year and a quiet year were different businesses. It arrived with no withholding, no payroll deduction, and no employer standing behind it setting anything aside. Every dollar that was going to survive had to be moved out of reach by a decision somebody made on purpose.

That is exactly the structure of 1099 income. Yours has fewer zeroes and the same architecture.

Which is why the useful lesson is not "spend less." Everyone already knows that, and knowing it has never once been sufficient. The lesson is that a large gross number does nothing on its own. What decides your outcome is whether there is a container underneath it, and for self-employed income the container is a Solo 401(k) or a SEP IRA.

The thing an employee gets for free

A W-2 employee with a payroll 401(k) has structure imposed on them. Money leaves before it lands. The decision is made once, at enrollment, and then never again.

Nobody does that for a contractor. There is no enrollment moment, no default, no automatic anything. The Federal Reserve's 2024 household survey found that 59% of self-employed adults reported income that varied month to month, against 28% of employees — so the group with the least imposed structure is also the group with the most variable cash flow.

Put those two facts together and the failure mode writes itself. Spending calibrates to the best month. Saving waits for a month that feels safe. The good year passes through.

Gross income is the number everybody quotes and the least useful one

Notice how the Tyson story is always told. The headline figure is what he earned. The comparison is against what he owed. The number nobody ever mentions is what he had actually set aside along the way, because as far as the record shows there was very little to mention.

Self-employed people do the same arithmetic on themselves constantly. You know your gross. You have a rough sense of your expenses. You almost certainly do not know, without looking it up, what you have in retirement accounts and what you contributed last year.

That asymmetry is not an accident. Gross is visible — it arrives in your bank app, it is what you tell people, it is the number on the 1099. Contributions are invisible unless you deliberately go and look, and there is no employer sending you a statement to remind you.

So the first practical move is not a contribution at all. It is picking one number — the balance in the account, not the revenue — and making that the number you actually track. Everything else follows from which figure you have decided is the score.

What the structure actually looks like

Pick the container before the strong year, not after. A Solo 401(k) lets you put away up to $72,000 in 2026 across the employee and employer sides, or $80,000 if you are 50 or older, with the employee deferral capped at $24,500. The deferral is a flat dollar amount rather than a share of profit, which is why it usually shelters more than a percentage-based plan at the same income.

Use the deadline as the forcing function. A SEP IRA can be opened and funded up to your filing deadline including extensions, so you can decide what a year could afford after the year is over and you can see the real numbers. That is a genuinely different mechanic from a payroll plan. Here is how a SEP IRA works, and here is the two accounts compared directly.

Move the money on the day it arrives, not at the end of the month. The gap between a big deposit and the decision to save part of it is where the money goes. Contribute out of the payment, not out of what is left.

Know the cost of the account you open. Whoever holds your retirement money is paid somehow, and you should be able to read exactly how in plain language. Ours is written out here.

The uncomfortable part

There is no income level at which structure becomes optional. A man who earned a reported $400 million proved that at the top of the range, in public, with court filings attached.

If your income is irregular and taxed as self-employment, the question that decides your retirement is not how good your best year was. It is how much of that year you moved somewhere it could not be spent.
