Hoops Rumors Glossary: Luxury Tax Penalties

Although some NBA teams can become hard-capped during a given league year if they use specific exceptions or make certain transactions, the league doesn’t have a set hard cap for all teams. In addition to its soft cap though, the league does have a luxury tax threshold, which serves to discourage excessive spending. When a team’s total salary ends up over that line at season’s end, the NBA charges a tax for every extra dollar the club spends.

The formula to determine the luxury tax line is a complicated one, related to the NBA’s projected basketball related income (BRI) and projected benefits. Generally though, it comes in around 20-22% above the salary cap line. For instance, in 2021/22, the league’s salary cap is set at $112,414,000, while the luxury tax threshold is at $136,606,000. So any team whose total ’21/22 salary exceeds $136,606,000 on the last day of the regular season is subject to a tax bill.

The NBA’s luxury tax system is set up so that the penalties become more punitive if teams go further beyond the tax line. Here’s what those penalties look like:

• $0-5MM above tax line: $1.50 per dollar (up to $7.5MM).
• $5-10MM above tax line: $1.75 per dollar (up to $8.75MM).
• $10-15MM above tax line: $2.50 per dollar (up to $12.5MM).
• $15-20MM above tax line: $3.25 per dollar (up to $16.25MM).
• For every additional $5MM above tax line beyond $20MM, rates increase by $0.50 per dollar.
  • Note: This would mean $3.75 per dollar for amounts between $20-25MM, $4.25 for $25-30MM, etc.

For example, if a team is over the tax by $12MM, its tax bill would be $21.25MM: $7.5MM for the first $5MM over the tax, $8.75MM for the $5-10MM bracket, then $5MM for the final increment in the $10-15MM bracket.

While these are the rates that apply to most taxpayers – including the Clippers, Nets, Bucks, Lakers, Jazz, and Sixers this season – a team can become subject to a more punitive “repeater” penalty if it paid the tax in three of the previous four seasons.

This scenario currently applies to Golden State — the Warriors were a taxpaying club in 2018, 2019, and 2021, which means they’ll be a repeat offender this season. The Thunder, who were taxpayers in 2018, 2019, and 2020, would also be subject to the repeater tax this season, but they’re far, far below the tax line.

Here are the penalties that apply to repeat taxpayers:

• $0-5MM above tax line: $2.50 per dollar (up to $12.5MM).
• $5-10MM above tax line: $2.75 per dollar (up to $13.75MM).
• $10-15MM above tax line: $3.50 per dollar (up to $17.5MM).
• $15-20MM above tax line: $4.25 per dollar (up to $21.25MM).
• For every additional $5MM above tax line beyond $20MM, rates increase by $0.50 per dollar
  • Note: This would mean $4.75 per dollar for amounts between $20-25MM, $5.25 for $25-30MM, etc.

If the hypothetical team we described in our first example, over the tax by $12MM, was a repeat taxpayer, its bill would increase to $33.25MM.

Generally speaking, luxury tax penalties are calculated by determining a team’s total cap hits at the end of the regular season. So a team that starts the year above the tax line could get under it before the end of the season by completing trades or buyouts. The Celtics did just that this season, slipping below the luxury tax threshold at the trade deadline by completing a series of deals that reduced their overall team salary.

It’s also worth noting that team salary for tax purposes is calculated slightly differently than it is for cap purposes. Here are a few of the adjustments made at season’s end before a team’s tax bill is calculated:

• Cap holds and exceptions are ignored.
• “Likely” bonuses that weren’t earned are removed from team salary; “unlikely” bonuses that were earned are added to team salary.
• If a player with a trade bonus is acquired after the final regular season game, that trade bonus is added to team salary.
• If a player with 0-1 years of NBA experience signed a minimum-salary free agent contract, the minimum-salary cap charge for a two-year veteran is used in place of that player’s cap charge.
  • Note: This only applies to free agents, not drafted players. For example, Clippers rookie Brandon Boston Jr. (second-round pick) and Lakers rookie Austin Reaves (UDFA) are each earning $925,258 in 2021/22. Boston will count for $925,258 for tax purposes, while Reaves will count for $1,669,178.

So let’s say that five teams finish the season owing a total of $50MM in taxes. Where does that money go? Currently, the NBA splits it 50/50 — half of it is used for “league purposes,” while the other half is distributed to non-taxpaying teams in equal shares. In that scenario, the 25 non-taxpaying teams would receive $1MM apiece.

As cap expert Larry Coon explains in his CBA FAQ, “league purposes” essentially covers any purpose the NBA deems appropriate, including giving the money back to teams. In recent years, the NBA has used that money as a funding source for its revenue sharing program. Coon also notes that the CBA technically allows up to 50% of tax money to be distributed to non-taxpaying teams, but there’s no obligation for that to happen — in other words, the NBA could decide to use 100% of the tax money for “league purposes.”
