The deadline for a 2014 RMD withdrawal was 12/31/14.

See IRS information below and this link for more detail: http://www.irs.gov/Retirement-Plans/Retirement-Plans-FAQs-regarding-Required-Minimum-Distributions:

What happens if a person does not take a RMD by the required deadline?

If an account owner fails to withdraw a RMD, fails to withdraw the full amount of the RMD, or fails to withdraw the RMD by the applicable deadline, the amount not withdrawn is taxed at 50%. The account owner should file Form 5329, Additional Taxes on Qualified Plans (Including IRAs) and Other Tax-Favored Accounts, with his or her federal tax return for the year in which the full amount of the RMD was not taken.

Can the penalty for not taking the full RMD be waived?

Yes, the penalty may be waived if the account owner establishes that the shortfall in distributions was due to reasonable error and that reasonable steps are being taken to remedy the shortfall. In order to qualify for this relief, you must file Form 5329 and attach a letter of explanation. See the instructions to Form 5329.
