For the 2025-26 season, the NBA’s salary cap is set at $154.647 million — yet teams routinely carry payrolls well above $200 million. How is that possible? Because unlike American football’s hard cap, the NBA operates a “soft” cap: teams may exceed it through a toolbox of exceptions, but a stack of higher spending thresholds then punishes overspending with escalating taxes and roster-building restrictions. Here is how the system actually works, and why it keeps breaking up contenders.

A soft cap, not a hard ceiling

The salary cap exists to promote competitive balance — to stop the richest owners from simply buying every star. In a hard-cap league like the NFL, the limit is absolute. The NBA’s version is softer: teams are allowed to spend past the cap using league-approved exceptions, most famously to re-sign their own players. The trade-off is that every dollar above certain lines triggers financial penalties, and the further a team goes, the more of its team-building tools are taken away. The result is a system that behaves less like a wall and more like a staircase of consequences.

The five spending lines that run the league

For the 2025-26 season, the NBA officially set these thresholds:

• Salary floor: $139.182 million. The minimum every team must spend — 90% of the cap. Teams that fall short forfeit money to the league and lose their share of luxury-tax distributions.
• Salary cap: $154.647 million. The soft ceiling. Teams can exceed it using exceptions.
• Luxury tax line: $187.895 million. Cross it and the team pays a tax on every dollar above it.
• First apron: $195.945 million. Cross it and roster-building restrictions kick in — and certain moves hard-cap the team here.
• Second apron: $207.824 million. Cross it and team-building nearly freezes: most exceptions and trade tools disappear.

Think of it like tax brackets: each line a team’s payroll crosses changes the rules it plays under.

The luxury tax: a penalty on every dollar over

The luxury tax is a straightforward financial punishment. For every dollar a team’s payroll sits above the $187.895 million line, it pays the league a tax — and the rate climbs steeply the further over a team goes. For a first-time offender, the rate starts at $1.50 per dollar for the first $5 million over the line, rises to $1.75 for the next $5 million, then $2.50, then $3.25 — increasing by $0.50 for each additional $5 million bracket. Teams that pay the tax in consecutive seasons face even higher “repeater” rates. The collected tax money is shared around the league, with non-taxpaying teams receiving a cut — which is why frugal owners quietly root for their rivals to overspend.

The two aprons: where flexibility freezes

Introduced in the 2023 collective bargaining agreement, the two “aprons” are spending thresholds above the tax line that restrict how teams can acquire players — penalties beyond money. Above the first apron ($195.945 million), teams lose access to the full mid-level exception and must use a smaller taxpayer version instead; they cannot acquire players through sign-and-trade deals; and they cannot take back more salary than they send out in trades. Above the second apron ($207.824 million), the restrictions bite much harder: teams lose their mid-level exception entirely, cannot combine multiple players’ salaries to trade for one expensive star, cannot send cash in trades, cannot use sign-and-trades at all, and cannot trade first-round draft picks seven years into the future. A second-apron team can essentially only re-sign its own players and draft picks, sign players to minimum contracts, and make trades that do not increase payroll.

The exceptions: how teams legally spend over the cap

The reason payrolls can soar past the $154.647 million cap is the exception system. The most important is the Larry Bird exception — named after the Celtics legend — which lets teams re-sign their own free agents even if doing so takes them over the cap, the mechanism that allows franchises to keep homegrown stars. Then come the mid-level exceptions: for 2025-26, the non-taxpayer mid-level exception is worth $14.104 million, the smaller taxpayer version $5.685 million, and a room exception of $8.781 million exists for teams operating under the cap. There is also a bi-annual exception ($5.134 million, usable every other year) and a minimum-salary exception that always lets teams fill out rosters cheaply. The catch: using certain exceptions triggers a hard cap at one of the aprons — for example, acquiring a player via sign-and-trade hard-caps a team at the first apron, meaning it cannot spend a dollar above $195.945 million for the rest of that league year.

Why the numbers keep climbing

Every figure above rises with league revenue. Under the 2023 CBA, the two sides agreed to “cap smoothing”: no matter how much basketball-related income jumps in a single year, the cap may rise by at most 10% per season, preventing a sudden spike that would distort the free-agent market. The 2025-26 cap rose the full 10% — from $140.588 million to $154.647 million — driven largely by the league’s new broadcast rights deal kicking in. The climb is expected to continue: projections put the 2026-27 cap at roughly $165 million, with the second apron near $221.7 million. In other words, today’s “unaffordable” payroll is tomorrow’s normal — which is exactly why teams plan their spending years in advance.

FAQs

Why doesn’t the NBA just use a hard cap like the NFL?

It was a negotiated choice. The players’ union has historically preferred a soft cap because it lets teams keep paying their own stars, which pushes overall salaries higher. Owners accepted it in exchange for the luxury tax and apron restrictions that now restrain spending in other ways.

What happens to a team that spends below the salary floor?

Nothing good for the owner: the team must pay the shortfall to the league and forfeits its share of luxury-tax distributions to the other teams. The floor forces every franchise to spend at least 90% of the cap on players.

Has the second apron actually broken up good teams?

Analysts widely say yes. Since the aprons took effect, several contenders have traded away core players or let veterans walk specifically to duck under the apron lines, because the roster-building freeze makes it nearly impossible to improve — or even maintain — a second-apron roster.

Do these rules affect how much players earn?

Indirectly. Maximum individual salaries are set as percentages of the cap based on years of service — for 2025-26, up to $54.126 million for veterans with 10 or more years — so when the cap climbs 10%, the richest contracts climb with it. The system caps team spending, not the earning power of the very best players.
