Jeane Napoles, whose mother is currently being investigated over one of the country's biggest corruption scandals, earned widespread derision for her social media posts featuring flashy cars and a swanky condominium in the US.
"We read the newspapers. We follow the Internet. That is where we heard about her," said Bureau of Internal Revenue chief Kim Henares.
Government investigators allege Napoles' mother Janet, a businesswoman, helped members of the Philippine parliament embezzle 10 billion pesos (USD 230 million) in government funds.
The corruption scandal prompted thousands to march in the streets in massive rallies against graft.

Prior to the scandal, 23-year-old Jeane Napoles regularly took to Tumblr, Instagram and YouTube to document her high-flying lifestyle.
But after Filipino newspapers in June broke the news about her mother's alleged links to corruption, her posts drew anger in the impoverished country where many believe a few families are enriching themselves unfairly.
