Rollover of 401k Pretax to Roth 401k 2021 and Plan Pretax and Aftertax Contributions
For 2021 I did a partial rollover of pretax 401k to Roth 401k within the same plan. A mix of pretax and after tax fund remain in the 401k . When employed at this company 20 years ago, I did contribute both pretax and after tax . No contributions for 2021. The company had matching contributions, but I would have to find out if the company if the company matched pretax or after-tax.
The interview question " Did you make any after tax contributions to your 401k ? These would be contributions you made to the plan yourself, rather than being made by your company on your behalf?
Does this mean just for this rollover in 2021 or for the 401k account as a whole for all time ?
If I should check YES, how does this affect my taxes and what additional TT entries further in the interview ? And do I need to determine if the company made matching after tax contributions or is this base only on my after-tax contributions?
