Professional clubs (MLS, future Division 1, USL Championship / Premier):
Require clubs to submit rolling three-year financial plans that demonstrate they can meet projected player costs, operational expenses, and debt service from a combination of sustainable revenue and limited, transparent owner equity contributions.
Cap the amount of owner equity that can be injected in any three-year window relative to the club’s average annual revenue (for example, no more than 30–40% of average revenue as pure loss funding without corresponding revenue growth plans).
Introduce a squad cost ratio (wages + amortization of transfer fees + agent fees) as a percentage of relevant revenue, phased in over time. European experience shows pure “break-even” rules are easy to game; cost-control ratios are harder to circumvent.
Mandate independent audits and public summary reporting of key ratios so other clubs, the league, and the public can see the numbers.
Youth and amateur/development clubs:
Lighter, scaled requirements focused on transparency and basic solvency rather than hard caps. Require disclosure of major funding sources, multi-year facility and coaching commitments, and restrictions on parent companies using youth clubs primarily as tax or marketing vehicles.
Prevent the creation of “shadow” academy structures that spend at professional levels while claiming amateur status.
The Expansion Fee Reality Check
Current expansion economics make the need for rules obvious:
MLS expansion fees have reached $500 million (San Diego FC). That figure is paid for the right to join a closed league and is largely a transfer of wealth to existing owners and the league.
USL Championship expansion fees have sat in the $20–25 million range in recent cycles. These fees flow primarily to league headquarters rather than being shared with existing clubs, and many Championship sides still report multi-million-dollar annual operating losses.
Multiple USL clubs have folded or gone on hiatus in recent seasons even as the league continues to sell new franchises. Expansion fee revenue has become a significant portion of league income, creating a structural incentive to keep selling slots rather than ensuring the long-term health of existing ones.
A system that charges nine-figure entry fees while many clubs lose money every year is not self-sustaining. Sustainability rules would force both leagues and ownership groups to confront whether the underlying business model can support the product without perpetual owner subsidies or constant new entrants.
Defining “Sustainable Spending”
The hardest conceptual problem is defining sustainability when ownership wealth varies so dramatically.
Possible approaches:
Relevant revenue as the primary denominator (matchday, commercial, broadcasting, player trading profits within limits). Owner equity injections above a defined threshold would not count as “revenue” for spending purposes.
A luxury tax / soft cap hybrid for the top division: clubs can spend above the ratio but pay escalating taxes into a central pot that supports lower-division clubs, youth development, and parachute mechanisms.
Clear rules on related-party transactions (sponsorships from owner-linked companies must be at demonstrable fair-market value), drawing lessons from Premier League Associated Party Transaction (APT) disputes and UEFA’s ongoing battles with clubs.
Different thresholds by division. A USL Championship club and an MLS club should not be held to identical absolute numbers, but both should face the same principle: you cannot systematically spend far beyond what the club itself generates.
Billionaire owners would still be able to invest, but they would be required to do so in ways that grow the club’s actual revenue capacity rather than simply covering losses indefinitely. Shoestring operators would be protected from being forced into an arms race they cannot win.
Enforcement Tools That Can Actually Work
European experience shows that weak enforcement produces endless appeals, points deductions that feel arbitrary, and compensation claims between clubs (see Everton’s ongoing fallout and Burnley’s successful damages claim). American rules need sharper design:
Independent financial oversight body (not purely league-controlled) with the power to impose graduated sanctions: transfer embargoes, registration limits, fine structures tied to the size of the breach, and, in extreme repeated cases, sporting sanctions including points or eligibility restrictions.
Pre-approval mechanisms for major spending or ownership changes rather than purely retrospective punishment.
Settlement pathways that encourage clubs to agree to multi-year corrective plans instead of fighting every case in arbitration.
Limited and clearly defined appeal rights with expedited timelines so disputes do not drag across multiple seasons.
Public reporting of breaches and sanctions to create reputational as well as sporting cost.
The goal is rules that clubs can plan around rather than rules that reward the best lawyers.
Interaction with Parachute Payments
If promotion and relegation (or a more fluid system) is introduced, parachute payments become necessary to reduce the cliff-edge effect of dropping a division. How they interact with FFP matters:
Temporary relief model: Relegated clubs receive parachute payments that are partially exempt from spending ratio calculations for a defined period (e.g., two seasons), giving them time to adjust squad costs and commercial revenue downward.
Stricter monitoring model: Parachute clubs face enhanced scrutiny and tighter limits on new long-term contracts so the payments are used for orderly transition rather than one last expensive push.
A hybrid is likely best: limited, declining exemptions in year one, then full application of the rules with the parachute money counted as revenue but subject to the same cost controls.
Without clear interaction rules, parachute payments can simply become another form of soft budget constraint that delays necessary adjustments.
Why This Matters Now
MLS valuations have risen dramatically even while a majority of clubs have operated at a loss in recent reporting periods. USL continues to expand while individual clubs struggle with multi-million-dollar annual deficits. Expansion fees have become a primary revenue source for the second tier. None of this is a foundation for a durable pyramid.
Financial sustainability rules will not eliminate owner ambition or competitive imbalance. They can, however, force the system to confront whether growth is being built on rising franchise values and expansion checks or on clubs that can stand on their own commercial feet. That distinction will determine whether American professional soccer can support genuine sporting mobility or remains a collection of closed, subsidized franchises.
This is the unglamorous but necessary infrastructure work. Without it, every conversation about promotion, relegation, or a more open pathway remains theoretical.
