Some countries, including Austria, Belgium, Canada, Chile, Italy, Japan, Ihe Netherlands and Spain, also provide explicit tax incentives for training, over and above the standard deductibility of training costs and of wages paid to trainees and apprentices. Lessons from recent evaluations show that the effectiveness of tax incentives depends on their design. For example, a highly complex design can reduce take-up rates, result in sub-optimal lax-relief claims, or lead to high non-compliance rates.
