Holly has worked at Amazon for 20 years. She participates in the companys qualified retirement plan (i.e., 401(k) plan) and has only purchased Amazon stock through the retirement plan. Over the years she has contributed $180,000 to the plan and the employer has matched her contribution with an additional $180,000 for a total of $360,000 contributed to the plan. All of which was used to purchase Amazon stock. Hollys Amazon stock in the retirement plan is worth $4,600,000 (long term gain of $4,240,000). What is Hollys basis in the retirement plan? When Holly retires and begins to receive this money, how will it be taxed to her (i.e., what type of income is it)?
