Can I write off online course platforms?

Expenses for online course platforms are deductible if they maintain or improve skills required in your current job or business, or if they are required by your employer or law to keep your salary, status, or job. They are not deductible if they are for a new trade or business. For example, a graphic designer taking a course to learn advanced design software can deduct the expense, but a graphic designer taking a course to become a chef cannot.
