Harmful Preferential Tax Regime

The OECD defines a harmful preferential tax regime as one that:

• Imposes a low or zero effective tax rate on the relevant income.
• The regime is ring-fenced (that is, it does not offer its domestic tax-payers the same incentives for the same activity as are offered to foreigners).
• Operation of the regime is non-transparent and there is no effective exchange of information with other countries.
