SINGAPORE – Two brothers behind automotive company William’s Auto were sentenced to five to six months in jail on Sept 17 after being convicted of income tax and GST evasion offences, as well as money laundering.

The duo – Ang Ngoh Tee (William), 71 , and Ang Chai Heng (Winston), 63 – were also ordered to pay a penalty of $812,795 each.

In a joint statement on Sept 17 , the police and Inland Revenue Authority of Singapore (IRAS) said the company issued cash sales invoice for various services without charging GST, despite being GST-registered.

The company deals in the sale and purchase of new and used cars, and provides in-house car loan financing as well as car workshop services, court documents said.

Between 2013 and 2019 , cash payments received from these sales were deposited into a separate and non-corporate bank account – identified in court documents as an OCBC Money Max account – to evade taxes payable by the company.

The funds in this account were then distributed among the directors broadly proportionate to their shareholdings in the company. Over the years, William received at least $2 million and Winston received at least $1 million from this account.

William’s Auto understated its net profits in its income tax returns for the years of assessment 2015 and 2016 , with the wilful intent to evade tax, police and IRAS said, adding that this resulted in $219,978 of undercharged tax.

The company’s output tax – the GST that businesses charge and collect – was also understated in its GST returns between 2013 and 2017, resulting in $50,953 in undercharged GST.

In February 2018, Winston received a cash cheque of $20,000 issued from the OCBC Money Max bank account, which he deposited into his personal bank account in June 2018 .

He later issued three cheques totalling $143,845 from his personal bank account as partial payment for a car.

In May 2018, William also received a cash cheque of $20,000 issued from the OCBC Money Max bank account, which he deposited into his personal bank account on the same day. A few days later, he issued a cheque of $84,322 from his personal bank account as partial payment for a car.

Both Winston and William admitted that the payments made towards their respective cars were partially funded by their shares of the company’s undeclared cash sales.

By using these proceeds to purchase their cars, both men possessed assets that were partly funded by their benefits from wilful income tax evasion, which constitutes money laundering, the police and IRAS said.

It is an offence to conceal, disguise, convert, transfer, remove from jurisdiction, acquire, possess, or use benefits derived from criminal conduct. Offenders can be fined up to $500,000, jailed for up to 10 years, or both.

Those who wish to disclose past tax mistakes can refer to IRAS’ website for more information, while those looking to report malpractices related to tax evasion can fill in the Reporting Tax Evasion online form, provided by IRAS via FormSG.

Informants who provide information and documents that lead to a recovery of tax that would otherwise have been lost will receive a reward of 15 per cent of the tax recovered, capped at $100,000 .

新加坡——威廉汽车公司背后的两兄弟于9月17日被判处五至六个月监禁，罪名是逃税、逃消费税以及洗钱。

两人——71岁的Ang Ngoh Tee（William）和63岁的Ang Chai Heng（Winston）——还被勒令分别支付812,795美元的罚款。

9 月 17 日，警方和新加坡税务局 (IRAS) 在一份联合声明中表示，该公司虽然已注册消费税，但开具各种服务的现金销售发票时并未收取消费税。

法庭文件显示，该公司从事新车和二手车的买卖，并提供内部汽车贷款融资以及汽车维修服务。

2013 年至 2019 年间，公司通过这些销售收到的现金被存入一个单独的非公司银行账户——法庭文件显示该账户为华侨银行 Money Max 账户——以逃避公司应缴纳的税款。

该账户中的资金随后按董事在公司中的持股比例大致分配给了各位董事。多年来，威廉至少从该账户中获得了200万美元，温斯顿至少获得了100万美元。

警方和新加坡税务局表示，威廉汽车公司在 2015 年和 2016 年的所得税申报表中少报了净利润，意图逃税，导致少缴税款 219,978 美元。

该公司在 2013 年至 2017 年期间的 GST 申报表中少报了销项税（即企业收取和征收的 GST），导致少收 GST 50,953 美元。

2018 年 2 月，Winston 收到一张 20,000 美元的现金支票，该支票由 OCBC Money Max 银行账户开出，他于 2018 年 6 月将其存入了自己的个人银行账户。

后来，他从自己的银行账户开出了三张支票，总计 143,845 美元，作为购买汽车的部分款项。

2018年5月，威廉还收到了一张由华侨银行Money Max账户开出的2万美元现金支票，他当天就将支票存入了自己的个人银行账户。几天后，他又从自己的个人银行账户开出了一张84322美元的支票，作为购买汽车的部分款项。

温斯顿和威廉都承认，他们各自为购车支付的部分款项是由他们从公司未申报的现金销售额中获得的份额支付的。

警方和新加坡税务局表示，这两名男子利用这些收益购买汽车，其资产部分来源于他们故意逃税所得，这构成洗钱行为。

隐瞒、伪装、转换、转移、移出司法管辖区、获取、持有或使用犯罪所得利益均属违法行为。违者可被处以最高50万美元的罚款、最高10年的监禁，或两者并罚。

想要披露过去税务错误的人士可以访问新加坡税务局 (IRAS) 的网站了解更多信息，而想要举报与逃税相关的违法行为的人士可以填写新加坡税务局通过 FormSG 提供的“举报逃税”在线表格。

提供信息和文件，帮助追回原本会损失的税款的线人，将获得追回税款的 15% 作为奖励，最高奖励金额为 10 万美元。
