SEP IRA Contribution Limits 2013. You can contribute up to 25% of your total salary or 20% of your adjusted annual income to a SEP IRA, up to a limit of $51,000 in tax year 2013. This is almost twice the limit for 401(k) investors.
As an employee, if your SEP IRA allows for non-SEP contributions, then you can make tax-deductible contributions up to your maximum IRA limit â generally five or six thousand dollars, depending on your age. Typically, SEP IRA accounts are established by businesses with only a single employee, the owner.
