The world football governing body is looking to make the change as a way of preventing any post-World Cup financial crises which often accompany many federations, especially teams.
The full amount is set to be paid in advance of the tournament, rather than being split into a $2.5million preparation fee, and $10 million after the event.
Prize money awarded to the 32 World Cup qualifying teams is expected to get even bigger for the coming tournament. A record $400 million in prize money is expected to be in play next year.
That figure represents a 12 percent increase from the $358 million paid out to teams at the 2014 World Cup in Brazil.
