For the future--if you have no employees (or only your wife as an employee), and if you'd like/need to put away more money than is allowed by a SEP, consider setting up a solo 401K. It has higher limits (and a higher percentage of your first dollars, too. You could put away every dollar of the first $18K earned ($24K if age 50 or older)).
They are simple to set up.
It's too late to set one up for 2014, but you could do it now for 2015.
