What's the Cutoff for IRA Contributions?

Contributions can be made to your IRA all the way up until April 18th filing deadline.  If you're in a traditional IRA, contributions up to this date can also be claimed on your federal tax return.  The maximum contribution for 2015 (depending on your income) is $5,500, with an additional $1,000 exemption granted for those who are over the age of 50.
