_{Just facts, you think for yourself}

I saw a dataset yesterday that terrified me.

It wasn't a market crash or an inflation report.

It was a simple chart comparing two things:

1. Human cognitive processing speed by age.

2. The complexity of the US Tax Code.

Here is the problem.

The first line (your brain) starts a slow, gentle decline in your 60s. The second line (tax complexity) shoots straight up the moment you hit age 73.

That’s when the government forces you to start withdrawing money (RMDs), calculating IRMAA brackets, and managing tax torpedoes.

We call this collision point The Cognitive Tax Spiral.

It’s a nasty feedback loop where tax rules and aging interact to quietly erode your wealth.

And here is the kicker: Research shows that while our ability to handle complex math drops, our confidence in handling it stays exactly the same.

That gap? That’s where the money disappears.

We spent weeks tearing apart the IRS code and aging research to map out this trap.

Here is the uncomfortable truth about aging and money.

The "Smart Person" Paradox Here’s the irony: The smarter you are today, the harder you crash tomorrow. Why? Because you’ve built a complex life—multiple brokerage accounts, trusts, K-1s. You’re used to handling it. But the "invisible decline curve" is real. We explain why the tax code is basically an "exploit surface" waiting for you to slip up, and why mild cognitive impairment hits your financial skills first.

The Math Trap Hidden in Plain Sight You sell a vacation home. Two years later, your Medicare premiums jump by $6,000. Why? Because of a lag in the rules called IRMAA. We break down the "Tax Torpedo"—where a single extra dollar of income can trigger an 85% tax rate on your Social Security benefits. It’s not fair, but it is the law. [Read Section II: The Mechanics of the Spiral (Premium)]

The Calendar Lottery (73 vs 75) The government just made the math harder. If you were born in 1959, you start RMDs at 73. Born in 1960? You start at 75. If you and your spouse are on different clocks, your tax planning just got exponentially messier. We show you how to navigate the "Calendar Trap" so you don’t accidentally double your taxable income in a single year. [Read Section III: The New RMD Timeline (Premium)]

The "Widow’s Penalty" This is the hardest part to read. When a spouse dies, the survivor has to file as "Single" the very next year. The standard deduction gets cut in half. The tax brackets compress. But the RMDs? They stay the same. We explain why the surviving spouse often faces the highest effective tax rate of their life—and how to prep for it. [Read Section IV: The Tax Stack Collision (Premium)]

Complexity Debt What happens when you have 5 brokerage accounts, 2 trusts, and a password notebook that’s hard to read? You have "Complexity Debt." We look at the legal bottlenecks—like why requiring "two doctors" to prove incapacity is actually a terrible idea for your Power of Attorney. [Read Section V: The Cognitive Decline Multiplier (Premium)]

The Fix: The "RMD Autopilot" You can’t stop aging. But you can stop the spiral. We outline a 90-day plan to turn your finances into a "Sovereign System." This isn't about picking stocks. It's about setting up an "AGI Control Panel" and automating your withdrawal guardrails so the system runs even if you aren't looking at it. [Read Section VI: Automation as Defense (Premium)]

This report is about keeping the money you have when you aren't as sharp as you are today.

Build the system now, while it's easy.
