how much can i put into tsp and irs's
Participation in a Roth IRA is based on your annual modified adjusted gross income (MAGI). If you are married, filing jointly, and your income is above the 2012 annual limit of $183,000, you canât contribute to a Roth IRA that year. If your income is under the maximum, you can contribute up to $5,000 per year, or $6,000 for those 50 or older. The IRS has additional rules about minimum income and a phase-out of contributions if you make between $173,000 and $183,000 annually. You can contribute the maximum amount to your Roth IRA regardless of how much you put into your TSP account.
As long as you're eligible to participate in the TSP, you can contribute up to $17,000 annually to your account as of 2012. For those in the military, this amount represents the total allowable contribution from all types of pay combined, including basic pay, special pay, bonus pay and incentive pay.
