Investigation officers are responsible for conducting in-depth investigations where tax evasion is suspected, and taking penal action (including prosecution proceedings in appropriate cases) to create a deterrent to tax evasion.
In 2009-10, there were 5 Investigation sections.
Prosecution
One of the 5 investigation sections focuses on criminal investigation of tax evasion.
Tax evasion is a serious crime. If a person is convicted of tax evasion, the Inland Revenue Ordinance provides for a maximum custodial sentence of three years.
In 2009-10, the Department had completed prosecution on 3 cases involving the making of false or incorrect statements in connection with claims for dependent parent allowances. The 3 taxpayers in the cases were convicted and were sentenced to imprisonment for
6 weeks to 2 months. Prosecution was also instituted on 1 case involving omission of salaries income. The trial has been scheduled for September 2010 at the District Court. There was in the year another case of suspicion of profits tax evasion, which the Court gave verdict of not guilty upon completion of trial in November 2009. Property Tax Compliance Check
In addition to conducting audits on businesses, the Unit also carries out verification checks on the correctness of rental income reported by property owners. Commencing from
2006-07, the Department broadened the scope of review to cover cases with lower rental income. In 2009-10, compliance check was completed on 79,000 property tax cases (Figure 31).Figure 31 Results of the property tax compliance checks
