A statement read: "At a Shareholders' Meeting today, Premier League clubs voted to adopt a change to the Summer Transfer Window closing date for season 2020/21.
"This will move the closing date back to the traditional point at the end of August/early September. The 2020 closing date will therefore be 17:00 BST on 1 September [31 August 2020 being a UK Bank Holiday].
"Clubs agreed after discussing the topic at length at previous Shareholders' Meetings."
At the start of the 2018-19 campaign, clubs voted to bring the deadline to the day before the start of the season but were targeted by European clubs who could continue to sign players.
Liverpool manager Jurgen Klopp voiced his displeasure at the early closure of the window last season while former Tottenham boss Mauricio Pochettino also said teams were "vulnerable."
The league also announced that the 2020-21 campaign will begin on Aug. 8.
