Tax Administration Fishbowl Practice Test

The main idea is that there is a finite window to correct a filed return, and that window is three years from the filing date when no audit or investigation notice has been served. This three-year rule gives both taxpayers and the tax authority a clear period to adjust errors, after which amendments aren’t typically permitted unless specific exceptions apply. Since the scenario specifies there’s no audit notice, the return can still be modified within those three years. The other time frames—two, four, or five years—do not align with this standard limit: two years would cut the window short, while four or five would exceed what the law normally allows in this situation.
