Even if you're retired, you should consider contributing to a Roth individual retirement account (IRA), provided you earn some income from working. Single taxpayers with adjusted gross income (AGI) less than $105,000 and married taxpayers filing jointly with AGI less than $167,000 are eligible to make a nondeductible contribution to a Roth IRA. (Note: The Pension Protection Act of 2006 includes a provision that began adjusting the phase-out ranges for inflation.)
Contributions are phased out for married taxpayers filing jointly with AGI between $167,000 and $177,000 and for single taxpayers with AGI between $105,000 and $120,000. The maximum annual contribution is the lesser of $5,000 or $10,000 for married couples or joint earned income (unchanged from 2009). Pension, investment, and rental income are not considered earned income. Individuals age 50 and older can make an additional $1,000 catch-up contribution.
Roth IRAs are a flexible way to save for retirement. Contributions can be withdrawn at any time with no tax consequences. Earnings and capital gains can be withdrawn on a tax-free basis if a qualified distribution is made:
