Deductible educational expenses include amounts spent for tuition, books, supplies, laboratory fees, and similar items. They also include the cost of correspondence courses, as well as formal training and research you do as part of an educational program. Transportation and travel expenses to attend qualified educational activities may also be deductible. For more information, refer to Publication 970, Tax Benefits for Education; Chapter 12 and Tax Topic 513, Educational Expenses.

In some cases, you may be able to deduct the cost of classes you need for work. This deduction, however, would be subject to the 2 percent of AGI limitation, along with most other miscellaneous itemized deductions you list on Form 1040, Schedule A (PDF), Itemized Deductions.

To be deductible, your expenses must be for education that:

(1) Maintains or improves skills required in your present job, or

(2) Serves a business purpose and is required by your employer, or by law, to keep your present salary, status, or job.

However, these same expenses are not deductible if:

(1) The education is required to meet the minimum educational requirements of your job, or

(2) The education is part of a program that will lead to qualifying you in a new trade or business.

Educational expenses, related to your present work, that are incurred during periods of temporary absence from your job may also be deductible provided you return to the same job or same type of work. Generally, absence from work for one year or less is considered temporary.
