I Pay No State Income Tax, and Tax-Free Munis Still Came Up 1.1 Points Short

5:31 on a Monday evening in February, dining table, one paper envelope from the broker slit open with a butter knife, and I'm reading the words capital gain distribution on a 1099-DIV for a fund that was sold to me with the word tax-free in its actual name. $318 of it. Taxable. From the tax-free fund. I put the butter knife down and looked at the envelope for a while.

The fund held $30,000 of my money, my entire anything-besides-stocks allocation, snagged eighteen months earlier on the strength of a coworker's lunchtime sermon about keeping the government off your interest. Munis, he said. Tax-free, he said. He lives in Sacramento. I live in Tennessee, where the state income tax rate is not low, it is zero, and that difference turned out to be the whole story. The envelope on my table was the first clue I had ignored for eighteen months.

The deeper problem was not the $318. It was a table on page six of the fund's fact sheet, the one that shows taxable-equivalent yield, and the tiny footnote underneath it that assumed you pay state income tax. I had glanced at that table a dozen times without once reading its assumptions. Doing the math for my actual zip code, with my actual zero percent state rate, showed that the tax-free premium I reckoned I was buying had shrunk by about 1.1 percentage points. The exemption was real. It was just exempting me from a tax I had never paid.

a coworker's lunchtime sermon

Marcus from the analytics team preached this fund the way some people preach a gym they have actually joined. He had run the numbers for his own situation, in his own state, at his own bracket, and every number he quoted was correct, for Sacramento. I copied the ticker off his laptop between meetings and snagged the fund that Friday without running a single number of my own. The $30,000 was sitting in cash at 0.2 percent, so any move felt like progress. Progress, it turns out, has an address.

the word exempt, in bold

The brochure had a chart on the front, a 3.4 percent yield with the word exempt in bold underneath, and I want to be fair to that brochure cuz nothing on it was false. The fund's income was federally tax-exempt, as advertised. What it was, was incomplete. Exempt from which taxes, for which investor, standing in which state, was a question the bold word had no room for, and I did not ask it, cuz I figured Marcus had already answered it for me.

3.4 percent, federally exempt

For eighteen months the fund behaved. It paid around 3.4 percent, the share price drifted in a range narrower than my blood pressure, and every January a statement arrived showing federal tax-exempt income of approximately $1,010 a year. I filed it and forgot it. The tax software put the number on the correct line and charged me nothing federal on it, exactly as promised. What nobody flagged, cuz nobody in my house looked, was that the state exemption printed so prominently in the marketing was worth zero dollars in a state with no wage tax at all.

Then came the envelope. Funds like this buy and sell bonds under the hood, and when a year is busy enough they pass trading profits thru to holders as capital gain distributions, fully taxable, no exemption anywhere in sight. Mine paid $318, short-term gains mostly, taxed at my ordinary rate, which at a 24 percent federal bracket came to about $76. Slight numbers. But the principle of a tax-free fund mailing me a taxable form in February had a flavor I did not enjoy, and it sent me looking for the rest of the story.

the geography lesson on page six

I dug into the fact sheet that weekend and found the assumption doing all the work. The taxable-equivalent table assumed a state tax bill, and at Marcus's address that assumption is worth real money. Sacramento taxes wages heavily, his bracket stacks a state rate on top of federal, and for him the state exemption adds approximately 1.1 percentage points of after-tax yield. He was right, in Sacramento. I had copied his conclusion to a state with no wage tax, where that same 1.1 points was a coupon for a store that does not exist. The table was accurate for exactly one of us, and it was not printed for my copy.

running it against a treasury fund

So I built my own table, on paper, with my own numbers, and narrowed it down to two contestants. The muni fund's 3.4 percent yield, minus its 0.16 percent expense ratio, minus the tax bite from that $318 distribution, came to approximately 3.2 percent actually mine. A Treasury ETF yielding 4.4 percent, taxed at 24 percent federal and nothing at the state level, keeps about 3.34. Dead even, within rounding, except the Treasury version never mails me a surprise envelope. Selling the muni fund meant realizing $410 of appreciation and paying the capital gains tax on it, about $98, a cheap exit fee for a lesson with this much arithmetic behind it.

one point one, itemized

Itemized, the lesson reads short. Exempt is a claim about you. Every yield table carries an invisible passenger, an assumed address, and mine had been riding along unread for eighteen months. The proceeds moved into Treasury ETFs in two lots during the last week of February, and the first distribution in June will be ordinary interest, taxed plainly, with no bold words attached. Marcus still owns his fund, and for once we are both right, cuz he kept his zip code and I ultimately read mine.

The envelope is still in the kitchen drawer, next to the takeout menus and the butter knife that opened it. Some future Monday at 5:31, I expect I will laugh about a fund named tax-free mailing me a taxable form, and some year after that I will have forgotten the whole thing, which is how these lessons die. This February I did the subtraction instead. The next brochure that says exempt in bold can wait until I have read page six. Footnotes first. That is the whole religion now.
