摘要：In a tax-evasion model with profit tax, we reexamine and clarify the issues of neutrality and separability with imperfect detection of tax fraud. With this more realistic setting, we show that the profit tax is not necessarily neutral and the separability conclusion may not hold. Furthermore, the property of non-neutrality may coexist with that of separability or inseparability. However, in contrast to the traditional conclusion, raising the audit probability may reduce the tax compliance when the property of inseparability is present
