While there is no age limit you must have earned income to contribute. 

There is no longer an age limit for contributing to an IRA.  But you must have taxable compensation to contribute to an IRA.

A Roth IRA differs from a traditional IRA in that contributions aren't deductible and qualified distributions aren't included in income.
