We're playing catch up. we are by no means in a bad position but should have paid more attention and learned more much much sooner. We have 8 and 10 years until retirement all being well. We currently max out our 401k and 457b each year. We are hands off people everything is parked in target date funds and we are comfortable with that. We don't have a separate brokerage account, just an emergency fund and the employer plans.
We have more disposable income now and can afford to invest more than the maximums allowed in the 401 and 457. We are over the limit for an IHA/Roth. Back door Roth is an option, we don't currently have those, and a mega back door Roth maybe available soon via the 401k employers plan. I also recently discovered that I can contribute up to $32,500 a year to an employer provided TIAA 403(b) in addition to the 457(b) allowance.
We expect to be in a lower tax bracket in retirement, so saving tax now seems obvious but Im reading that having money in Roth which grows and is not subject to tax can help a lot with flexibility, diversification and options in retirement.
We don't have the funds to max the 403(b) and also the BD Roths, we could contribute just to the 403(b), or spilt the difference and max the BD Roths and put the rest in the 403 (b) or some other combination. Is it worth putting as much as we can in the 403 just 10 years from retirement? Also I don't know anything about their fee structure yet but what should I look out for, what would be considered too high? What might I not be considering because of limited knowledge of the subject?
