Maximum TSP, Roth IRA contributions


Q: In answering a previous question about maximum nondeductible contributions to Individual Retirement Accounts, you wrote: “Your participation in the Thrift Savings Plan should not prohibit you from making the maximum nondeductible contributions to a traditional IRA in 2009.” Is the answer the same if I have a Roth IRA instead of a traditional IRA? Can I max out both TSP at $22,000 and ROTH IRA at $6,000?

A: The rules are different for Roth IRA contributions. You’ll have to use an online calculator or the rules contained in IRS Publication 590 to see if you can contribute to both.
