Teams were required to be under the salary cap using the 'top 51' definition (in which the 51 highest paid-players on the team's payroll must have a combined salary cap). On March 13, teams were allowed to exercise options for 2023 on players with option clauses in their contracts, submit qualifying offers to their pending restricted free agents, and submit a Minimum Salary Tender to retain exclusive negotiating rights to their players with expiring 2022 contracts and fewer than three accrued seasons of free agent credit.

The 2023 NFL league year and trading period began on March 15. The playoffs are then scheduled to start on January 13, and conclude with Super Bowl LVIII, the league's championship game, at Allegiant Stadium in Paradise, Nevada, on February 11. The season is planned to begin on September 7, 2023, with defending Super Bowl LVII champion Kansas City hosting Detroit in the NFL Kickoff Game, and end on January 7, 2024. The 2023 NFL season is scheduled to be the 104th season of the National Football League (NFL).
