Wanting some to weigh in on the difference in the 2 investments and when to invest in each. Currently my DH contributes the max to traditional 401k. His company started offerig a Roth 401k about 2 yrs ago. He is at a point where the company will automatically contribute 10% of salary to traditional 401k no match required. We have discussed the benifits of reducing our current tax bill but wonder about future tax implications. He is at about 400k in his portfolio at 34yo. We talked about switching over to the Roth 401k when his tradition reaches 500k maybe another 2yrs. We think our Magi may completely box us out from being able to do our Roth IRAs at that point, thus losing one advantage of diverting $$from taxation now.
