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.
A Roth IRA is similar in some respects to a traditional IRA in that it is set up to be a source of retirement income. Penalties are assessed for early withdrawal. However, funds contributed to a Roth IRA are taxed prior to being deposited in the account, and qualified disbursements are tax-free.
