For me and my wife, it breaks down 43.95% pre-tax (trad 401(k) and IRAs), 23.11% Roth IRAs, and 32.94% taxable.
Actively we are putting the most into pre-tax through my work 401(k). She doesn't work outside the home presently, but depending on total income this year she will max out her trad IRA contribution. And I will max out my Roth this year, using backdoor if necessary.
Whatever is left goes into taxable. Actually I probably misspoke above, I bet we will put more into taxable than pre-tax all up, at end of year.
