I read in another thread here regarding contributing after-tax money to 401K plan. I wonder if anyone can help explain the reasoning behind it.
I currently max out my 401K, and do a backdoor roth. I also save extra (after tax $) to my vanguard account for retirement planning. So should I also divert some of my after tax $ to my 401K (assume plan allows it)? The only benefit I can see so far is there are options/funds available in my 401K is not available for individual investors in Vanguard (due to minimum investment requirement). And seems like fee structure is better for most of the funds in my 401K as well.
Any downside of doing it? (any catch?) I guess I won't be able to take the after-tax contribution in my 401K (at least not as easy as I could have from the vanguard personal account). We have cash liquidity on hand and I don't see ourselves need to pulling cash out of my 401K plan.
Also how does it work when I roll my 401K plan in the future, as there will be after tax and before tax amount, will the roll-over become a tax trigger event if I have gain in the after tax portion of the 401k??
thx!
