Yes, if it meets the criteria below.
Qualifying Work-Related Education
You can deduct the costs of qualifying work-related education as business expenses. This is education that meets at least one of the following two tests.
The education is required by your employer or the law to keep your present salary, status, or job. The required education must serve a bona fide business purpose of your employer.
The education maintains or improves skills needed in your present work.
However, even if the education meets one or both of the above tests, it isn't qualifying work-related education if it:
Is needed to meet the minimum educational requirements of your present trade or business, or
Is part of a program of study that will qualify you for a new trade or business.
You can deduct the costs of qualifying work-related education as a business expense even if the education could lead to a degree.
According to the IRS, "if you are self-employed, you can deduct your expenses for qualifying work-related education directly from your self-employment income on Schedule C. This reduces the amount of your income subject to both income tax and self-employment tax." At a 15% tax bracket plus 15% SE tax, that would be a 30% tax savings. That expense would go under the miscellaneous expense section.
