As retirement accounts, the Roth IRA and the TSP Roth have annual investment limits. The TSP Roth has a significantly higher investment limit than the Roth IRA. Investors will be able to put $16,500 in a TSP Roth, whereas a maximum of $5,000 can be put into a Roth IRA in 2011. A TSP Roth has a higher catch-up provision as well.
The other major difference between 401k and Roth IRA is the way they are managed. When you opt for 401k, you have no say in how the funds are controlled, and it is the sole prerogative of the employer to invest the funds. In Roth IRA, you are in better control of the funds.he major difference between the two lies in the manner the earnings are taxed. This is not significant if you have got a 401k plan where the employer makes a matching contribution. In Roth IRA, it is your money alone that goes into the fund, and is attractive as you get tax free earnings after retirement.
