Here's another bit along the same lines.
The Internal Revenue Service (IRS) states that compensation received in exchange for oocyte donation must be declared as income (The NABER Report, 1996). Participants were asked whether they thought that they would have to pay taxes on the compensation. Approximately half did pay taxes, but they were not always informed about this ahead of time. A number of women were shocked when a W-2 (tax) form arrived in the post, or their accountant informed them about this rule. Many of these women were frustrated not only because they thought the tax was unfair, but also because they did not know ahead of time, so they could set money aside. Women who did not pay taxes were under the impression that either it was not enough money to declare; it was reimbursement for pain and suffering and was therefore not taxable; or that it was a gift and was therefore exempt.
