Your MTM election effective this year has to be attached to your timely filed tax return without extensions.
In other words, making the election on your 2022 tax return won't let you tile MTM on that return.
IRS says: "It's important to note that in general, late section 475(f) elections aren't allowed."
If timely elected, you have to file MTM.
And you can't go back to the regular filing without IRS approval.
