The salary cap, explained without the jargon

On June 30, 2025, NBA Communications set the league salary cap for the 2025–26 season at $154.647 million. Roster payrolls across the league routinely exceed that figure without violating league rules. According to the NBA CBA 101 documentation, the collective bargaining agreement defines the salary cap as a limit on total team salaries, but that limit is subject to certain exceptions.

The baseline cap is not an arbitrary number. The CBA calculates the salary cap directly from projected Basketball Related Income, subtracts projected player benefits, and divides the resulting figure by 30. That formula creates the standard operating threshold for all 30 franchises.

Why Exceptions Allow Spending Past the Cap

Exceeding the $154.647 million baseline is built directly into the league structure through designated exceptions. The collective bargaining agreement establishes three distinct Mid-Level Exceptions, each tied directly to a team's total salary position.

For the 2025–26 season, NBA Communications outlined three exact tiers for these exceptions:

• The Room Mid-Level Exception sits at $8.781 million for a team that stays below the salary cap.
• The Non-Taxpayer Mid-Level Exception rises to $14.104 million for teams over the cap but under punitive spending levels.
• The Taxpayer Mid-Level Exception drops to $5.685 million for franchises spending above the tax line.

These mechanisms allow franchises to add talent even when total payroll exceeds the baseline cap. A team operating under the cap receives the $8.781 million room exception. Once a team crosses $154.647 million, it unlocks the $14.104 million non-taxpayer exception.

The Luxury Tax Level at 121.5 Percent

Crossing the salary cap does not trigger an immediate financial surcharge. Under the 2023 NBA Collective Bargaining Agreement, the tax level is set precisely at 121.5% of the base salary cap.

For the 2025–26 season, that formula places the tax level at $187.895 million.

When an executive refers to being over the cap but under the tax, they are describing the financial space between $154.647 million and $187.895 million. In that specific window, a franchise operates above the cap, utilizes the larger $14.104 million Mid-Level Exception, and incurs zero luxury-tax financial penalties. Once a roster's combined wages pass $187.895 million, the team enters the tax system and sees its Mid-Level Exception cut to $5.685 million.

First and Second Apron Thresholds

Above the tax line, the CBA introduces two distinct tiers known as aprons. The NBA's June 28, 2023 CBA summary explains that the first apron sits approximately $7 million above the tax level, while the second apron is set at $17.5 million above the tax level.

For 2025–26, NBA Communications calculated the first apron at $195.945 million and the second apron at $207.824 million.

The transition between these numbers is where spending limits convert into hard roster restrictions. The league confirmed that teams above the first apron face explicit limits on the types of roster moves they can execute. At $195.945 million, spending restrictions cease being purely financial.

The Four Tiers of Roster Construction

The 2025–26 figures outline four clear operating zones:

1. Under $154.647 million: Cap room teams with the $8.781 million room exception.
2. $154.647 million to $187.895 million: Over-the-cap teams with the $14.104 million non-taxpayer exception and zero tax penalties.
3. $187.895 million to $195.945 million: Taxpayer teams using the smaller $5.685 million taxpayer exception.
4. $195.945 million and $207.824 million: First and second apron tiers where the league enforces roster-building limits.

Team construction depends on navigating these specific financial markers, where moving past $187.895 million triggers tax bills, and crossing $195.945 million or $207.824 million restricts the mechanics of player acquisition.
