Two proposals to enhance tax compliance are discussed within the conte
xt of the Dutch income tax. Both proposals use prospect theory and are
supported by empirical data. First, it is argued that deliberate over
withholding of income taxes will further the tendency to comply. Secon
dly, it is demonstrated that offering the taxpayer a choice between fu
ll itemised deduction or a considerable overall standard deduction wil
l enhance compliance as well as considerably reduce the efforts needed
by the tax authorities to prevent income tax evasion.
