I recently opened a new self employed 401k (or solo 401k) plan. I set up one plan with two accounts, one for my husband and one for me.
It all started when I got an email from David at My Two Dollars  who was looking to compare self employed tax deferral options for his own business. As I was pointing out some pros and cons, I realized that I could use one of these myself!
Even though I’m beginning to withdraw retirement contributions, instead of contribute them, I remembered that it would allow me an easy way to facilitate my unconventional Roth IRA strategy to lower our tax bill .
One of the big advantages over a traditional 401k, is that you don’t need to contribute until your tax filing deadline  (plus extensions). It will open up an option to shelter additional money, if needed, after you file your taxes.
The deadline to set up a new plan is December 31, however, you don’t need to make any contributions when you set it up. I don’t plan to make a contribution until we know exactly how much we will need to defer at tax time.
The contribution limits for 2008 are:
- $15,500 deferral of your pre-tax income (less any contributions made to a 401k at your regular job).
- Profit sharing contribution up to 25% of your pay, with a maximum of $46,000.
- Total contribution is the sum of the deferral and profit sharing, limited to 100% of your pay.
Because of the two different types of contributions, it can get a little tricky to figure out, because you must account for self employment tax in the calculation. Here is a helpful calculator to determine your maximum contribution .

The only downside is that to access the index funds with .10% expense ratio, you need a minimum of $10,000 in each fund.
The process to set up the plan was easy. I couldn’t do it online, but I filled out the forms and sent them in. My new accounts were established within a week. It was painless.
Solo 401k Tidbits
Reporting. Once the plan reaches $250,000 in assets, you must complete a Form 5500. I used to complete these for clients back when I worked in Employee Benefits, so that shouldn’t be a problem.
Employees. The solo 401k is for you and your spouse only. Part-time employees who work less than 1000 hours per year can be excluded.

Other Self Employed Tax Deferral Options
I selected the solo 401k, mainly because it usually gives the option to shelter as much income as possible, allowing more room to execute various tax strategies.
If you have a small business, there are other options you can consider including a SEP IRA and Simple IRA. Here is a great comparison  of all three.
