Ho Chi Minh City tax officials recently collected VND10.8 billion (US$509,100) that 11 people allegedly evaded by concealing their incomes.
A retailer, identified only as T., topped the list by failing to pay more than VND2.2 billion ($103,730) on incomes he earned as chairman of a company and board member of many others.
T., a builder, was found to have evaded payment of VND1.85 billion.
The lists includes several more in retailing and some in real estate.
Tran Thi Tuyet Hoa, head of the department's personal income tax office, said the 11 only declared and paid tax on one source of income, but data collected by the department between 2009 and 2011 found they had "very large" incomes from other sources.
Hoa said the highest rate of 35 percent is imposed on an annual income of more than VND960 million ($45,300). Vietnam's GDP per capita in 2012 was $1,596.
"We will continue to check for such evasion to guarantee fairness in tax collection."
But lawyer Tran Xoa said tax officials are being lenient with the rich, only pulling them up now, four years after the Personal Income Tax Law took effect.
Those evading taxes have to be publicly named and reported to the police, he said.
