There is a specific tax definition of passive income, known as “passive activity” to the Internal Revenue Service. Passive income is any income you make without actively working or are materially involved. The IRS defines it as any rental activity or any business in which the taxpayer does not “materially participate.” Nonpassive activities, or active activities, are businesses in which the taxpayer works on a regular, continuous, and substantial basis.
“Let me remind you again that when you put a book out there, you are a published author in a space where you are an expert. Your book becomes the ultimate business card, not to mention a source of ongoing revenue. Did someone say “ongoing revenue?”. Who does not need to make some extra money on a regular basis? Realize that this book will take some work to complete once, but thereafter it exists forever – working to bring you royalty checks five, ten, twenty years from now. Money will be consistently flowing into your bank account. If you write a good book that provides real value, then you realistically have a revenue stream which will bring income for decades to come.”
