"Stop modern slavery! Wage increase now!" read placards held by the domestic workers who marched from a downtown square to Hong Kongs government headquarters.
The protesters demanded the government scrap a 400 Hong Kong dollars ($51) tax on employers that was introduced in 2003 when Hong Kongs economy was in recession, and raise their minimum monthly salary to the original level of HK$3,670 ($471).
Eman Villanueva, a protest organizer, said the tax has undermined their ability to support families back home, where prices are much lower than those in Hong Kong and a small reduction in pay will greatly affect their families livelihood.
"HK$400 a month is enough to provide a monthly rice supply for a family of six in the Philippines," Villanueva said.
The maids, who have repeatedly protested against the wage cut, chanted "Bring back HK$3,670, abolish the levy!" as they marched.
More than 218,000 foreigners work as domestic helpers in Hong Kong. Most come from the Philippines, with smaller numbers from Indonesia, Thailand and Nepal.
