Dutch tax officials have ruled that a woman can deduct about $2200 that she spent on a witchcraft-training class, on the grounds that she was using the class to "extend her professional knowledge."
Apparently, she was training for her employment as an actress and artist, not specifically for witchery. But the class featured instruction in the use of crystal balls, spells, and herbs. Herb use is relatively common in the Netherlands, as I recall, but I can't think of too many non-witch professions where it would be a job requirement.
The course's teacher, Margarita Roland, says that she teaches her apprentices how to become witches so that they can use magic as a force for good. On her website, she wears a pointy hat.
