Hi all, I know that if I contribute $17,000 to a 401k, I can also contribute $5,000 to a Roth IRA. But what about a 401k and a Roth TSP? I had a 401k at my old job earlier this year, and contributed $7,000 (PRE-tax dollars) since January 2012. Switched jobs and now have a Roth TSP (limit is $17,000)...
