What Is the MLB Luxury Tax?

The Competitive Balance Tax (CBT) — universally known as the "luxury tax" — is MLB's mechanism for discouraging excessive payroll spending by wealthy clubs. Unlike a hard salary cap (which MLB does not have), the luxury tax allows teams to spend beyond a set threshold, but charges them an escalating penalty for doing so.

The goal is twofold: slow the financial arms race among large-market teams and redirect some of that money toward revenue sharing and player benefits.

How the Thresholds Work

Under the current CBA, there are multiple CBT thresholds, each triggering higher tax rates. The exact dollar figures are adjusted periodically, but the structure is consistent:

Threshold Tier Approx. Payroll Level Tax Rate (First Offense)
First Threshold ~$237 million 20%
Second Threshold ~$257 million 32%
Third Threshold ~$277 million 62.5%
Surcharge Tier ~$297 million 80%+

Rates increase for repeat offenders. Numbers are approximate and subject to CBA adjustments.

What Counts Toward the CBT?

The CBT is calculated using Average Annual Value (AAV) of all 40-man roster contracts, not the actual cash paid in a given year. This means a $300 million, 10-year contract counts as $30 million per year against the tax — regardless of how the payments are actually structured.

This is why you see some contracts heavily backloaded: teams may defer payments to future years, but the CBT hit remains the same. It can be a cash-flow strategy rather than a tax-avoidance strategy.

The "Reset" Incentive

One of the most controversial aspects of the luxury tax is the reset provision. A team that goes below the first threshold for one full season resets its tax rate to "first offense" status the following year. This incentivizes large-market clubs to strategically strip payroll — even during competitive windows — to avoid the highest repeat-offender rates.

Critics argue this functions as a soft salary cap in practice, because even wealthy teams are reluctant to pay 80 cents in taxes for every dollar they spend above the surcharge threshold.

Where Does the Tax Money Go?

Revenue collected through the CBT is distributed as follows:

  • A portion goes to the Industry Growth Fund, which supports baseball development programs.
  • Another portion supplements player benefits.
  • Some funds support revenue sharing among lower-revenue clubs.

How This Affects the Cubs

The Cubs have historically operated near — but not dramatically above — the first luxury tax threshold. Front-office decisions around trading veterans, non-tendering arbitration-eligible players, and structuring extensions are all filtered through the lens of CBT management. Understanding the luxury tax helps fans decode moves that might otherwise seem puzzling.
