MLB Payroll Rules in 30 Seconds

Major League Baseball is different from the NFL, NBA and NHL.

MLB does not currently have a salary cap.

A team can theoretically spend:

$150M

$250M

$350M

or even more.

Instead of a hard cap, MLB uses the:

Competitive Balance Tax — CBT

Usually called the:

Luxury Tax.

For 2026:

### Base CBT Threshold # $244 Million

Teams that exceed it pay penalties based on:

  • how far above the threshold they spend
  • how many consecutive years they've been over it

At the highest spending levels, penalties aren't only financial.

Draft position can also be affected.

Worked examples use illustrative teams and simplified numbers to teach the rules. They are not live payrolls or approvals of real transactions.
