Efficiency Effects of Tax Deductions for Work-Related Expenses
CESifo, Munich, 2004
CESifo Working Paper No. 1311
In this paper it is shown that allowing the deduction of work-related expenses has a strictly positive effect on tax efficiency only if two conditions hold jointly: (i) The expenses should be interpretable as real cost and (ii) the expenses should be required for increasing taxable income. Otherwise deductions are inefficient, neutral or ambiguous. Thus it is argued that the cost of commuting to work should not be deductible as commuting does not increase taxable income. The efficiency enhancing effect of deducting other expenses like educational ones or expenses for housework and child care is challenged on the grounds that these expenses are largely pecuniary costs.
