Wisconsin tax tidbit: Roth conversions

April 2, 2010

Wisconsin flag Wisconsin residents who convert their traditional IRAs to Roths this year won't have to worry about doing double tax calculations. Badger State lawmakers have adopted the same Roth conversion rules as Uncle Sam.

Whenever Congress makes changes, federal-state tax law conformity is always an issue. Many times and for many reasons, states don't follow the U.S. tax code and that creates all sorts of headaches for filers.

But thanks to a new Wisconsin law, all of the state's higher-income taxpayers who opt under the new federal law to turn their old IRAs into Roths this year also will be able to postpone, if they wish, their state tax payments on converted amounts until they file their 2011 and 2012 returns.

In addition, the law that provides IRA conversion conformity also adopted certain provisions of the federal Heroes Earnings Assistance and Relief Tax Act of 2008. That law provides several benefits for members of the military.

Wisconsin officials say that residents who in 2008 or 2009 adjusted for income differences that were allowed at the federal level but not on their state returns may now file an amended Wisconsin income tax return (Form 1X) to reverse the adjustments.

And taxpayers who have not as yet filed their 2009 Wisconsin income tax returns may ignore the state's Schedule I adjustment for the Heroes items.

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.)
