Team fouls decide when ordinary fouls become free throws.

How officials sort it

1. Identify the foul type: personal, shooting, offensive, player-control, team-control, technical, unsportsmanlike, flagrant, or another special category.
2. Check whether the foul counts toward that team's team-foul total under the rulebook being used.
3. Confirm the current period, quarter, half, or overtime because team-foul counts reset or carry over differently by competition.
4. Decide whether the offended team is already in the penalty or whether this foul puts the team into the penalty.
5. Administer the correct result: throw-in, free throws, counted basket plus a free throw, free throws with possession, or another special penalty.

What team fouls mean

Team fouls are a running count of fouls charged to one team. The count helps stop a team from repeatedly fouling to slow the game, stop drives, or avoid scoring chances without giving up free throws. Before the penalty limit is reached, many ordinary non-shooting defensive fouls simply give the offended team the ball for a throw-in. After the limit is reached, those same kinds of fouls can send the offended player to the free-throw line.

The exact count is not universal. Some competitions count by quarter, some by half, and some have overtime or late-period details that change how the penalty is reached. That is why "the fifth foul," "the seventh foul," or "the tenth foul" only makes sense after the rulebook and game level are known.

What the bonus is

The bonus is the free-throw penalty that begins after a team has committed enough team fouls in the relevant period. It does not mean every whistle creates the same result. It means the defense has used up its allowed number of common team fouls before non-shooting fouls become more costly.

Bonus formats vary. Some rulebooks use automatic two-shot free throws after the team-foul limit. Others use a one-and-one format at one stage, where the shooter earns a second free throw only by making the first, and then move to two shots after a later threshold. Professional, international, college, high-school, youth, and local competitions do not all use the same table.

Bonus is not the shooting-foul rule

A shooting foul is handled through the shooting-foul penalty even if the fouling team has not reached the bonus. If the shot is missed, the shooter generally receives free throws tied to the value of the try. If the shot is made and counts, the usual result is the basket plus one free throw.

The bonus mainly matters for non-shooting fouls. A defensive reach before the shot, a hold away from the ball, or illegal contact during a cut may be a throw-in when the team is under the limit, but free throws once the team is in the penalty. Officials therefore decide shooting status before using the team-foul count to choose the penalty.

When bonus free throws may not apply

• Offensive and player-control fouls: many rulebooks do not award bonus free throws for a foul by the team that has control of the ball. The usual result is a turnover or throw-in for the opponent.
• Team-control fouls: some codes use a broader team-control category that prevents bonus free throws while the fouling team has team control.
• Special fouls: technical, unsportsmanlike, flagrant, intentional, disqualifying, and fighting-related fouls have their own penalty rules. They may include free throws and possession even without the ordinary bonus calculation.
• Dead-ball or pre-throw-in contact: contact before the ball becomes live, during a throw-in setup, or after a whistle can be treated under special timing rules instead of the normal common-foul path.
• Rulebook-specific exclusions: youth leagues, modified rules, and tournament rules may change which fouls count and which fouls create bonus shots.

How the count is enforced

The scorer tracks team fouls and usually displays the count on the scoreboard or scorer's table equipment. Officials still have responsibility for knowing whether a team is in the penalty before administering the next restart. If the crew is unsure, they can confer with the table before the ball is put back in play.

If a free throw is wrongly awarded or wrongly omitted because of a team-foul count mistake, many rulebooks treat the situation as a correctable error only within a limited window. Once play has resumed past the allowed correction point, the mistake may stand even if the original count was wrong. The exact correction rule depends on the competition.

Misunderstandings

• "They are not in the bonus, so there cannot be free throws" misses shooting fouls and special fouls. Those can create free throws before the team-foul penalty is reached.
• "They are in the bonus, so every foul is two shots" is too broad. Offensive fouls, team-control fouls, technical categories, and one-and-one formats can change the result.
• "The scoreboard foul count decides the rule" is incomplete. The count matters, but the officials still need the correct foul type and the correct rulebook penalty.
• "Bonus rules are the same at every level" is wrong. The basic idea is shared, but counts, resets, one-and-one rules, overtime treatment, and special exceptions vary.

How to read common plays

• Defender reaches before the shot: if the offense is not yet shooting, the result may be a throw-in when the defense is under the team-foul limit, but bonus free throws once the defense is in the penalty.
• Shooter is hit on a missed three-point try: the free throws come from the shooting-foul rule, not from the bonus. The team-foul count may still be updated if that rulebook counts the foul.
• Ball handler charges into a legal defender: the foul is on the offensive player. In many competitions the opponent gets the ball, not bonus free throws, even if the offensive player's team has many fouls.
• Hard off-ball grab late in the game: the crew first decides whether it is an ordinary personal foul, a bonus foul, or a special foul such as intentional, unsportsmanlike, clear-path, or flagrant-type contact.
