Choice between pre-tax, after-tax, ROTH
A quick background:
I'm 36, wife, 2 kids and hoping to FIRE in 11 years. My company has an ESOP and I hope/plan on my account reaching about $3.5 million at that time. We're currently saving about $45k/year into our retirement accounts, 401K, ROTH 401K, and ROTH IRA. Also saving another $20k/year into my brokerage account. We are just about maxed at the 28% tax bracket.
When I leave the company, the ESOP money will get rolled into a traditional IRA. I am thinking SEPP 72t to get access to the funds. My goal is to have $2.5 million saved in our various other accounts.
My question is, which account should I be putting my current retirement money? Knowing that my future $3.5 million will be pretax from my ESOP, Should I try to sock away more into ROTH to offset....or more into traditional 401k to keep my current tax rate out of the 33% bracket?
(also, I understand the risk of having a large portion of my net worth tied up in my employer. But, it is a great place to work and even though I have had offers from other companies, my company currently pays me about 25% higher than what I could expect elsewhere)
