If you still want to make a 2014 contribution to your traditional IRA there is still time – most taxpayers have until April 15, 2015 to make their 2014 contribution.
Contributions can be made to your traditional IRA for a year at any time during that year or by the due date for filing your return for that year, not including extensions.
Don’t forget about the 70½ rule though… traditional IRA contributions cannot be made for the year in which you reach age 70½ or for any later year. Contributions can only be made to your traditional IRA for each year that you receive compensation and have not reached age 70½.
