Tax Bureau Mod

On a fixed cycle the mod checks each player's inventory for diamonds. When a player holds diamonds, one is taken as tax, and the player gets a chat notice that the tax cycle ran. A player who has no diamond at the check is not left untouched, since the missing payment carries a penalty instead: a slowness effect is applied as a consequence, so evading taxes has a cost.

The economy runs entirely on the server, with no separate setup on the player side, so the mod suits survival servers that want a recurring cost built into the game. Its commands let server owners tax a particular player, change which item is taxed, set the amount, and adjust the interval between tax cycles, with the default cycle at 20 minutes and a 1 second tick of the check.

The mod is distributed for Fabric and NeoForge. Its files cover 12 game versions 1.21 – 1.21.11, with 2.0.0 as the latest file on each loader, and it is released under the MIT License, not open source. Only the server needs it to run the taxes; players may leave it out, so installing it on the server alone is enough.
