Jennifer Christie, Twitter's vice president for people, later confirmed the details in a blog post. Certain jobs that require physical presence, such as maintaining servers, will still require employees to come in.
When the coronavirus first started spreading widely in the United States, companies were hesitant to be the first to switch to a work-from-home model.
If and when tech workers do go back, their corporate campuses - once known for free food, communal activities, shared bikes and other perks - could look vastly different, making staying home more appealing.
'That will remain our top priority as we work through the unknowns of the coming months'.
Twitter is "uniquely positioned to...allow folks to work from home given our emphasis on decentralization and supporting a distributed workforce capable of working from anywhere", Christie wrote.
The microblogging site also stated that it was unlikely that any of its offices will open before September and even when they do open "they won't be a snap back to the way it was before".
The social media company also said there will also be no business travel prior to September "with very few exceptions" and a moratorium on in-person company events for the remainder of 2020.
"We will assess 2021 events later this year", it said.
The news comes following word from Google and Facebook that they are likely to continue telework through the end of the year for most employees.
