Pre-tax vs after tax investment choices

[the_fixer]

Hello,

Wife has an IRA with Fidelity, all pre-tax 401k money and we are getting ready to change her investments.

We were planning to do one of the lazy portfolios and as I have been researching I came across this info from Paul Merriman and he has two different categories one for pre-tax  and one for after tax.

I would like to understand why he would differentiate between the two and if we need to select different options based on pre-tax (the wife) and after tax (myself) accounts?

We will likely go with a simple 3 or 4 lazy portfolio

 feel like I am missing something tax related and do not want to mess up.

It depends how finely you want to sharpen your pencil.

See Tax-efficient fund placement for some details.
