Tax evasion is proscribed as a crime under Art 125 of Federal Tax Administration Proclamation no-983/20081. Under this article, the law proscribes transgressions such as understatement of income (evasion of assessment), failure to file tax return with intent to evade tax and evasion of payment as offenses of tax evasion. To prove tax evasion, prosecutors must prove all ingredients of the offense, namely intent to defraud, affirmative act and evaded tax. Amongst the ingredients of crime of tax evasion, the existence or otherwise of evaded tax is a typical one. One should use evidence to identify the nature and amount of evaded tax. We can prove tax evasion both by direct and indirect evidence.
