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.
In fact, you might not have all the information necessary to calculate your maximum SEP-IRA, since the amount you can contribute depends on the amount of income you had for the year. You can wait until the April 15 tax filing deadline to make your SEP-IRA contribution for the prior year. Filing Extensions. If your business needs to file an extension, that extension also gives you extra time to make your SEP-IRA contribution. If you file a six month extension by the April 15 deadline, you have until October 15 to make your annual SEP-IRA contribution.
