Generally, work-related self-education expenses are tax-deductible if they enhance skills and knowledge or lead to an income increase related to current income-producing work, for the person claiming the deduction.
Self-education expenses include the costs of courses at an education institution (whether leading to a formal qualification or not), courses provided by a professional organisation or an industry organisation, attendance at work-related conference or seminars, self-paced learning and study tours (whether within Australia or overseas).
Self-education expenses are tax-deductible if your income-earning activities are based on the exercise of a skill, or some specific knowledge, and self-education enables you to maintain or improve that skill or knowledge; and/or the self-education objectively leads to, or is likely to lead to, an increase in your income from your income-earning activities in the future (eg through a real opportunity of promotion, or eligibility for a higher pay grade or bonus).
You cannot deduct self-education expenses if the education is undertaken or designed to obtain employment, obtain new employment, or open up a new income-earning activity (whether in a business or in current employment). A deduction is also not available if you weren’t undertaking income-earning activities to derive assessable income (either by employment, carrying on a business or other means) at the time you incurred the self-education expense.
For self-education expenses that are only partly deductible, you need to apportion the amounts spent and claim only the part that relates to an income-earning purpose.
