Kogan.com has blamed “now apparent avoidance of GST” by a number of overseas websites selling into Australia for a decrease in its global brands revenue in the September quarter.

Kogan (ASX:KGN) fell by a third to $3.12 in early Monday trade.

The online retailer told investors gross margins had decreased as a result of competition from foreign websites selling into Australia without GST, as well as a general decline in the strength of the Australian dollar.

“New GST laws on low value eCommerce import transactions were introduced on 1 July 2018,” the company said.

“Initially, this saw some competitors exit the market and the Company’s July Revenue grew 33% year-on-year.

“More recently, widespread avoidance of GST has become apparent.

“At this stage, the Company is unable to determine whether the recent widespread avoidance of GST will be temporary.”
