William’s Auto’s tax case centred on cash sales that did not make it into the company’s accounts. The Singapore car business was GST-registered but issued cash invoices for services without charging GST, while proceeds were routed through a separate account. Reporting puts the resulting income tax and GST undercharge at S$270,930. 3

How the cash-sale scheme worked
Keeping the proceeds outside the company’s accounts understated its reported income. Failing to charge GST on cash invoices also left GST unaccounted for. The conduct described in the reporting ran between 2013 and 2019. 4

Ang Ngoh Tee, known as William, and Ang Chai Heng, known as Winston, were directors of William’s Auto. The company also had a third director, Chng Mathew, who died in 2019. The available source excerpts identify him as a director but do not establish his precise role in the transactions, so the brothers’ convictions should not be attributed to him. 3

Where the proceeds went
One report says that, between 2013 and 2019, William received more than S$2 million and Winston more than S$1 million from the separate account. It also says both used undeclared cash to help fund personal car purchases in 2018. Those figures do not provide a complete accounting of the proceeds or establish how much each brother spent on a car. 7
Sentences and the limits of a statutory comparison
On 17 September 2026, William was sentenced to five months and 28 days in jail, and Winston to five months and three days. Each was ordered to pay a S$812,795 penalty following convictions relating to income tax evasion, GST evasion and money laundering. 2

A legal commentary describes general ceilings of up to four times the tax evaded for wilful tax evasion, and a fine of up to S$500,000 or up to 10 years’ imprisonment, or both, for money laundering. But the available case excerpts do not establish which maximum applied to each specific charge. Those general ceilings should therefore not be treated as a precise measure of the brothers’ sentences or penalties. 11
