Recently, the academy has been dealing with increasing pressure due to the allegations of sexual transgression of the husband of one its board members.
She has since quit, as have the academy's head and four other members.
The academy said it meant to bestow the 2018 literature award in 2019. "On five of those occasions, the prize was delayed then awarded at the same time as the following year's prize", the Academy said in a statement.
With the academy depleted by resignations and its secretive workings exposed to unflattering scrutiny, the Nobel Foundation, which manages industrialist Alfred Nobel's legacy and oversees all of the awards, stepped in to warn that the scandal risked tarnishing the prizes as a whole. No worthy victor was found in 1935.
The Nobel Prize is a set of annual global awards bestowed in several categories by Swedish and Norwegian institutions in recognition of academic, cultural, or scientific advances.
The Academy said the decision was made "in view of the now diminished Academy and the reduced public confidence in the Academy".
Resigning was not possible until earlier this week, when the academy's patron, King Carl XVI Gustaf, approved changes in the statutes allowing members to resign.
It is believed the #MeToo marketing campaign in Hollywood, which highlighted the prevalence of sexual assault within the film business, performed an element within the resolution. Instead, it will reveal two winners in 2019. Last year, Japanese-born British novelist Kazuo Ishiguro won it. His lawyer, Bjorn Hurtig, denied all allegations, claiming his client was the victim of "a witch hunt".
Boy Scouts Will Change Program Name to 'Scouts BSA'
This is the first marketing push since the Boy Scouts announced late past year it would open its ranks to girls . For 108 years, the Boy Scouts of America's flagship program has been known simply as the Boy Scouts.
The organisation later voted against removing Mr Arnault's wife, the poet and writer Katarina Frostenson, from its committee.
The academy provided funds to the Kulturplats Forum, a cultural center run by Arnault and Frostenson, which also represented a conflict of interest. It was not until 27 years later - in 2016 - that the Academy finally condemned the fatwa against Rushdie.
The controversy comes from Jean-Claude Arnault, a prominent figure in Swedish cultural institutions.
"The Swedish Academy intends to decide on and announce the Nobel Prize in Literature for 2018 in parallel with the naming of the 2019 laureate", according to the statement.
The decision however, does not affect the other Nobel prizes, which are awarded separately.
This is not the first time this has happened. United States author William Faulkner received his award in 1950, one of five occasions when the prize was awarded at the same time as the following year's prize. No prize was awarded that year.
