# Contributions and Tax Points

An active residence is required to make contributions and earn Tax Points (TP).

Both Contributions and Tax Points are earned on a 1:1 ratio with INIT spent.

For every 1 INIT used in minting units or paying rent, players receive:

* 1 Contribution (sent to their city of residence)
* 1 Tax Point (added to their wallet)

**Impact on Gameplay**

The balance between contributions and sabotage influences a city's [Radiation level](https://docs.civitia.org/game-mechanics/city-radiation) and base rent prices.

**Contributing to Cities**

Contributions are automatically sent to the player's city of residence.

Players automatically earn SILVER 1:1 when contributing to their city of residence.

**Sabotaging Mechanics**

Tax Points accumulate in the player's wallet and can be used for sabotage when visiting a city.

Once used for sabotage, Tax Points cannot be reclaimed.
