i401(k) and annual contribution limits
Here is the basic situation:
In the past, a single LLC (LLC 1) has generated the vast majority of HHI. Enough that the standard $17.5K plus 20% net income got both me and DW to the ~$50K/year/person contribution limit (i.e., $100K total pretax).
Moving forward, LLC 1 will be scaling down and definitely won't generate enough net income to get both me and DW to the $52K limit for 2015. A new LLC (LLC 2) will start generating significant income in 2015. For the sake of this discussion, let's say in 2015 LLC1 will generate just enough to get one of us to the $52K limit and LLC2 will generate just enough to get the other one of us to $52K.
So my question is this, for purposes of i401(k) contributions and in particular the "profit sharing" component, are those tied to the LLC or just to our household/passthru income? Put another way, will we need to open another i401(k) and "tie" it to LLC 2 for net income profit sharing, or can I continue to funnel all contributions through the existing i401(k)?
