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.
Within IRS limits, contributions into a SEP IRA are generally 100% tax deductible to the employer. SEP IRA contributions are made by the employer into their own SEP as well as to the individual SEP account of each eligible employee. Investment earnings grow tax deferred.
