Q. How do I report a broken SEPP? 

A. Start with IRS Form 8606 – if it doesn’t apply (no non-deductible contributions), don’t use it.
Then go to Publication 590 (as directed by the instructions for 8606) to the section “Is it Taxable?”.

I’ll save you a little time – go to page 50, top right…’Recapture tax for changes in distribution method under equal payment exception.’

Then follow the instructions in Publication 590 to use IRS Form 5329 and report the transaction on IRS Form 5329. ‘Report the recapture tax and interest on line 4 of Form 5329. Attach an explanation to the form. Do not write the explanation next to the line or enter any amount for the recapture on lines 1 or 3 of the form’.

The instructions for line 4 of 5329 state to report it on IRS Form 1040, line 58 or IRS Form 1040NR, line 54.

It is never simple and the instructions are seldom in one place. Good Luck!
