Company A is a sole prop owned fully by Jane Doe
Jane Doe & John Doe also own Company B, a partnership 50% each.

With Stock Attribution, they both own 100% of both companies.

Company A has one additional employee not related.

Company A has earnings of $56,461
Company B has a loss of $19,478

How much of the net earnings and ownership % would you allocate to John vs. Jane Doe to calculate the contribution for the age weighted Profit Sharing plan ?

Any ideas??? It would seem that the partnership can NOT have anything due to the loss.

Although 401(k) plans are "classified" by the IRS as Profit sharing plans, they really have nothing to do with whether or not the employer actually makes a profit or not. The decision to allocate a contribution by the employer is controlled by other issues not the posting of a profit in a particular year.
