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.
This means your employer can contribute the maximum allowable contribution to your SEP IRA and you can contribute the maximum personal contribution to your traditional IRA in the same tax year. As of 2013, the maximum contribution your employer can make into your SEP IRA is $51,000 or 25 percent of your compensation, whichever is less. The tax-deductible amount of your contribution shrinks as you approach personal income limits.
