In Minecraft PvP, especially in version 1.8.9, CPS (Clicks Per Second) refers to how frequently you send attack packets to the server. While it is not a direct "stat" like health, high CPS is highly valued in competitive play for two main reasons:

 Knockback Reduction: Every time you land a hit, the game engine processes it in a way that slightly resets your momentum. By clicking at a higher rate (e.g., 15+ CPS), you flood the server with attack packets, which effectively reduces the knockback you take when you are hit in return. This makes your character feel "heavier" and allows you to maintain your forward movement, making it easier to start or continue combos.

 Hit Registration: Minecraft servers process game logic in "ticks" (20 times per second). When an opponent is hit, they have a short "invulnerability frame" (i-frame) window where they cannot take damage. High CPS increases the probability that your attack packet lands the exact millisecond their invulnerability wears off, ensuring you don't miss opportunities to deal damage.

Regarding your mention of "taxes," this is not a mechanical term in Minecraft PvP. It is likely a misunderstanding of community jargon or inside jokes:

 In the context of the Minecraft YouTuber Technoblade, his community often joked about "paying taxes" to him as an authority figure, or "stabbing orphans" as a meme, which sometimes leads to confusing overlaps in fan discussions on platforms like Reddit.

 There is no game mechanic where you "pay taxes" to gain CPS or combat advantages; any suggestion otherwise is likely a community meme rather than a technical game feature.
