I think I read some where that if you have a rollover IRA (from a previous employer) and you add any contributions to it, it can cause your earnings to become taxable, or basically that you should never co-mingle the monies.
Here is what I did, let me know if it could be a problem. I rolled over an old 401k about 7 years ago. I wanted to start contributing to a Roth, but for about 4 months I accidentally contributed pre-tax money to my rollover tira. Once I realized what I was doing, I changed all distributions to my Roth, and have been that way ever since. Again, this was about 7 years ago.
My tira (rollover) has just been sitting idle ever since, obviously it has grown over time, but I just wonder if I caused any tax headaches that I'll have to address at some point.
Thanks in advance.
