# GST and contributions

Commonview calculates contributions differently depending on whether the body corporate is registered for GST or not.

### Body corporates registered for GST

Commonview will use the GST exclusive costs to calculate contributions. GST will then be added to the final contribution amounts to be invoiced.

<p class="callout info">{{@50#bkmrk-contributions-calc-registered}}</p>

The total contribution amount will be displayed inclusive of GST, and include a breakdown of the GST component.

### Body corporates NOT registered for GST

Commonview will use the GST inclusive costs to calculate contributions, as the GST amounts are recognised as an expense.

<p class="callout info">{{@50#bkmrk-contributions-calc-not-registered}}</p>

The total contribution amount will be shown without any GST applied.
