Do overall 401(k) contribution limits sum across employers?
Let me first start off by saying that you need to be careful with an S-Corp and defined contribution plans.  You might want to consider an LLC or some other entity form, depending on your state and other factors. You should read this entire page on the irs site:  S-Corp Retirement Plan FAQ, but here is a small clip: Contributions to a Self-Employed Plan You can’t make contributions to a self-employed retirement plan from your S corporation   distributions. Although, as an S corporation shareholder, you receive   distributions similar to distributions that a partner receives from a   partnership, your shareholder distributions aren’t earned income for   retirement plan purposes (see IRC section 1402(a)(2)). Therefore, you   also can’t establish a self-employed retirement plan for yourself   solely based on being an S corporation shareholder. There are also some issues and cases about reasonable compensation in S-Corp.  I recommend you read the IRS site's S Corporation Compensation and Medical Insurance Issues page answers as I see them, but I recommend hiring CPA You should be able to do option B.  The limitations are in place for the two different types of contributions:  Elective deferrals and Employer nonelective contributions.  I am going to make a leap and say your talking about a SEP here, therefore you can't setup one were the employee could contribute (post 1997). If your doing self employee 401k, be careful to not make the contributions yourself. If your wife is employed the by company, here calculation is separate and the company could make a separate contribution for her. The limitation for SEP in 2015 are 25% of employee's compensation or $53,000.  Since you will be self employed, you need to calculate your net earnings from self-employment which takes into account the eductible part of your self employment tax and contributions business makes to SEP.  Good read on SEPs at IRS site. and take a look at chapter 2 of Publication 560. I hope that helps and I recommend hiring a CPA in your area to help.
