Sooooooooo much easier than doing a backdoor roth and about 5X more capacity in a Mega Roth than the 7 or 8K you can do in a backdoor. Lots of places have Roths, but very few have Mega Roths (maybe 10%?). Guessing lots of employees don't even know about the few that are there. IIRC, the 2025 deferral number is $80,000 total. That crushes the extra $8 you could do in a backdoor Roth.
