Allocating Losses to S corporation Shareholders


A loss is allocated to each shareholder on a daily basis. This means, if you sell your stock before year-end, and the corporation ends up with a loss for the year, you cannot deduct the entire loss. You must allocate the loss according to the number of days you owned the stock and your percentage interest in the corporation.

Example:
  • You sell all your stock on June 30, 2020.
  • You owned a 50% interest from January 1, 2020 through June 30, 2020 (181 days).
  • The corporation has a $10,000 loss for the year ending December 31, 2020.
  • The daily loss is $27.39726 ($10,000/365).

Your may deduct: $2,479 ($27.39726 x 181 x 50%).
