I attended a year-long program to become a health coach. Is this a tax deduction? If so, under personal or business?

Work-Related Education (Personal itemized deductions on Schedule A)

You can deduct expenses you have for education if the education meets at least one of the following two tests.

• It maintains or improves skills required in your present work.
• It is required by your employer or the law to keep your salary, status, or job, and the requirement serves a business purpose of your employer.

You can't deduct expenses you have for education, even though one or both of the preceding tests are met if the education:

• Is needed to meet the minimum educational requirements to qualify you in your trade or business, or
• Is part of a program of study that will lead to qualifying you in a new trade or business.
