Convert tradition IRA to Roth IRA new law

[jducker99]

under the new law Michigan passed Public Act 4 of 2023

Under Michigan's Public Act 4 of 2023, retirement income becomes fully exempt from state taxes in 2026 for those born in 1969 like me. Does this full exemption apply to Roth IRA conversions? If so, could I convert in 2026 without paying Michigan state tax on the converted amount?

The phase-out seems tied to birth year rather than age 59½—can you confirm I don't need to wait until 59½ to qualify for the state exemption? The law's details are tricky to parse.

Can i convert next yr and avoid state tax or will it be exempt later based on the wording of conversions?

Michigan will not tax retirement income including a Roth conversion in 2026. Of course it will be taxed by the IRS.
