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.
â Employer contributions to a SEP-IRA will not affect the amount an individual can contribute to a Roth or Traditional IRA. However, if you contribute to a defined contribution plan (401(k), IRA, etc.), annual additions to an account are limited to the lesser of $49,000 or 100% of the participantâs compensation.
