Covid restrictions caused substantial losses at Trump resorts in Ayrshire and Aberdeenshire with both companies reducing staff.
Trump Turnberry saw turnover more than halved and it recorded a loss of more than £3m in 2020.
The other course and resort at Balmedie also reported a loss, of £1.3m.
Donald Trump's mother came from the Isle of Lewis, and the former US president is said to have spoken fondly of his Scottish ancestry.
He opened his first golf resort on the Menie estate in Aberdeenshire in 2012, amid opposition over potential environmental damage, and later tried to stop a wind farm being built off the coast, arguing it would spoil the view.
In 2014 he bought the Turnberry golf resort in South Ayrshire from a Dubai-based company.
He handed control of both courses to his sons Donald Junior and Eric shortly before he became president in 2017, but he retained a financial interest.
Critics of Mr Trump recently lost a legal bid to force the Scottish government to investigate how he paid for the courses, using an unexplained wealth order.
