Skillshare is more of a social learning platform where you can teach real-world skills. The range of skills that you can teach is only limited by your imagination - from board game strategies, garment construction, cooking tutorials, travel hacking, and relationship tips. I even saw a course on how to build a grown man's wardrobe. Creating a class on Skillshare is free. For each student who enrolls, Skillshare takes a 30% fee (Similar to Udemy). You are also provided a unique teacher referral link that lowers the fee to 15% for students who enroll via your referral. Note that all online courses on Skillshare go through an approval process based on specific criteria. https://image.slidesharecdn.com/passiveincomepromoslideshow-171117120611/95/passive-income-pros-and-cons-1-638.jpg?cb

When a taxpayer records a loss on a passive activity, only passive activity profits can have their deductions offset instead of the income as a whole. It would be considered prudent for a person to ensure all the passive activities were classified that way so they can make the most of the tax deduction. These deductions are allocated for the next tax year and are applied in a reasonable manner that takes into account the next year's earnings or losses.
