I don't know how things work with a trust but if it was a simple inheritance from a parent to a child you do have to ensure RMDs are made in the year of the person's death.

Then you have to take RMDs from inherited IRAs based on your age. And then the account has to be fully transferred from its tax friendly state by the end of year 10.

The IRS confused people with this and they haven't enforced penalties for people who didn't do this in 2022 and 2021. I've been told the IRS is supposed to finally published rules on this by the end of CY2023 but we'll see.

For now I just plan to start taking withdrawals and will take most of them over the next 5-6 years where my income should be the lowest.

Now idea what rules apply to a trust. I once had one but my current attorney didn't see any reason to keep it once I got married. We had no children so things might be simpler.
