To identify the correct name for the compound with the formula $\text{CaSO}_4$, let's analyze the provided options.

1. **Calcium(II) sulfate**: This name indicates that calcium is in the +2 oxidation state, which is correct, as calcium typically forms a +2 cation ($\text{Ca}^{2+}$). The sulfate ion ($\text{SO}_4^{2-}$) also has a -2 charge, so this name is valid.

2. **Calcium sulfate**: This name refers to the same compound, generally accepted for $\text{CaSO}_4$. It is a widely used and recognized IUPAC name.

3. **Calcium sulfur tetroxide**: This name suggests a different composition and is inaccurate for $\text{CaSO}_4$. The prefix 'tetra-' indicates four of something, which does not apply here.

4. **Calcium sulfoxide**: This name is also incorrect since sulfoxides are a different class of compounds entirely and are not suitable for representing sulfate.

### Final Answer
The correct names for the compound $\text{CaSO}_4$ are **Calcium sulfate** and **Calcium(II) sulfate**. However, the most commonly used and straightforward name is **Calcium sulfate**.
