Your "Tax-Free" Bond Might Cost You 42 Cents on the Dollar
Schwab has a page on municipal bond tax traps. Solid page. They walk through private activity bonds and the AMT. Then they give you this:
If you have to pay AMT and hold such a bond, your interest income would generally be taxed at the applicable AMT rate, which could be 26% or more, if you're in the AMT exemption phase-out range. Effectively, that means the yield on a municipal bond paying 3.50% would drop to roughly 2.6%.
Sure. Except that number is wrong for the people who need it most. The math skips the bump zone. And the bump zone is where your money burns.
The Bait
Private activity bonds fund airports. Housing projects. Stadiums. They look like any other muni bond. Tax-free interest. But a little fatter yield. Maybe half a percent more than a plain general obligation bond.
That extra yield is the tell. It exists because PAB interest is a "preference item" under the Alternative Minimum Tax. Regular income tax? Free. AMT? Not free. The market knows about the tax thing, so they pay you a little more to hold it. You take the extra yield. You hope you never owe AMT.
The Seven-Year Nap
For most of you, that hope held. The 2017 Tax Cuts and Jobs Act knocked AMT from five million filers down to about 200,000. Almost nobody owed it. Planners stopped screening for PAB exposure. People loaded up on fat muni yields and never checked the label.
Seven years. Nobody checked the pipes.
The Pipe That Cracked
The One Big Beautiful Bill changed the wiring. Starting in 2026, the AMT exemption phaseout threshold drops to $1 million for joint filers. And the phaseout rate doubles. From 25% to 50%.
Under the old rules, a married couple could hit $1.8 million in AMT income. The exemption survived all the way up. New math chops that down. The $140,200 exemption burns off twice as fast. Gone by about $1.28 million.
The rate doubling is the real damage.
Earth's biggest energy source: near Grand Canyon
For a century, America fought wars over energy buried six thousand miles away.
The largest energy source on Earth was under our own feet the whole time - much of it beneath the desert near the Grand Canyon.
How big?
50,000 times every oil and gas reserve on the planet.
Combined.
The center of the Earth runs as hot as the sun's surface.
Tapping a sliver of it could power civilization for two million years.
The size was never the problem. The reach was - until a drilling crew hit the DOE's 2035 targets twelve years early, and costs fell 50% in 18 months.
Google signed. Gates invested. The Pentagon made it a priority.
One company has quietly built this for sixty years.
The Bump Zone
Follow one dollar.
You earn $1 of PAB interest. It lands in your AMT income as a preference item. That's $1 on the taxable pile.
But you're inside the phaseout band. So that same $1 also kills 50 cents of your exemption. Now there's $1.50 sitting on the pile.
The AMT rate at this income level is 28%.
28% of $1.50 is 42 cents.
I mean, you just paid 42 cents in tax. On one dollar of income you thought was free.
That's not 26%. That's not 28%. It's 42%. Every single dollar inside the bump zone between $1 million and $1.28 million works the same way. The dollar hits. The exemption shrinks. The tax bites 1.5 times harder than the rate suggests. Right?
The Yield Killer
Now run the real number on that 3.5% PAB yield.
3.5% times (1 minus 0.42) equals 2.03%.
A taxable Treasury paying 4.3% nets you more after taxes. Even in the top bracket. You bought the expensive bond. You thought it was the cheap one.
Schwab told you 2.6%. The bump zone says 2.03%. That gap is real money on a $500,000 muni position.
NVIDIA’s shocking new investment (NOT AI)
Did you know NVIDIA doesn’t make all its money from AI chips?
The company is now a heavyweight venture capitalist.
The investment arm doesn’t reveal the stocks it holds…
But I did some digging…
And discovered it’s heavily invested in one little-known company in Wyoming’s high desert.
The company is working on a crazy new technology (not AI)...
In an industry that could soon explode by 33,000% thanks to a new executive order.
The Fix
Look, this is not hard to check. Your 1099 has a line for AMT interest. If that line has a number, you hold PABs.
If you own a muni fund, pull up the prospectus. Vanguard's VTEB scrubbed the PABs out. So did iShares' MUB. But actively managed muni funds? Closed-end funds? Individual bonds your advisor picked in 2019? You have to look. Every one of them. The prospectus will show the PAB percentage.
This is already in effect. Rules changed January 1, 2026. That still leaves the rest of the year to swap.
The Shrug
Schwab gave you the AMT rate. They skipped the phaseout math. The effective rate inside the bump zone is 42%, not 28%. Your 3.5% yield is 2.03%, not 2.6%.
Read your 1099. Check the AMT line. That's the number nobody published. Now you have it.
