What is not a source of income?

Not a source of income refers to any activity or asset that does not generate money or financial gain for an individual or entity. This could include hobbies, personal interests, social activities, or possessions that do not contribute to one's financial well-being.

Examples of not a source of income could include volunteering for a charitable organization, participating in sports or recreational activities, owning a pet, or collecting memorabilia. These activities may provide personal fulfillment, enjoyment, or other non-monetary benefits, but they are not considered a source of income because they do not generate revenue or profit.
