State muni bond tax system upheld

May 19, 2008

States and municipal bond managers are breathing easier today.

The U.S. Supreme Court just ruled that it’s OK for states to exempt the earnings from the bonds they issue, but collect taxes on bonds issued by other states. We blogged about this case back in October and November.

Forty-two states offer such exemptions for their municipal
bonds.
An estimated $2.5 trillion
is invested in the municipal bond market. And n
early 500 mutual funds invest in bonds from specific
states to take advantage of the tax  breaks.

The 7-2 high court decision (Justices Anthony Kennedy and Samuel Alito dissented) overturned a Kentucky court ruling that the state’s tax breaks for its bonds violate the Commerce Clause of the U.S. Constitution.

Not so, wrote Justice David Souter for the court majority:

"For the better part of two centuries states and their political subdivisions have issued bonds for public purposes, and for nearly half that time some states have exempted interest on their own bonds from their state income taxes, which are imposed on bond interest from other states. The question here is whether Kentucky’s version of this differential tax scheme offends the Commerce Clause. We hold that it does not."

Hello Tax Season 2026

Happy New Tax Year! Are you ready to file your 2025 tax return? I know, too early to ask. But Tax Day 2026 will be here before we realize it. The Internal Revenue Service deadline to file and pay any tax we owe is the regular April 15 date this year. It’s also Tax Day for most of the states that collect income taxes from their residents, which is most of the states! If that seems too far away right now, don’t worry. As is the case every tax season, the ol’ blog’s tips and other tax reminders should help all of us meet our state and federal responsibilities. Procrastinators also will want to keep an eye on the countdown clock just below. It tracks how much time we have until April’s Tax Day, just in case we put off our annual tax task until the absolutely final hours and decide we need to instead get an extension request into the IRS by that date. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
