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.
You can also make your traditional IRA contributions for the year to the SEP-IRA. These contributions count toward your annual contribution limit for traditional IRAs, but not towards the employer contribution limits to the SEP-IRA.or example, as of 2013, you can't deduct any of your traditional IRA contribution if you also have a SEP and your MAGI exceeds $69,000. If you're married filing jointly, the limit goes up to $115,000.
