Do Condo fees include HST in the price?

You can't assume anything... you have to read your HOA booklet as it should specifiy what they do and don't cover in your fees.

What is HST by the way?

Unless HST is a tax of some type, this post is NOT appropriate to this forum.

HST is a sales tax, Harmonized Sales Tax. It is a combination of GST and PST (goods n services & provincial sales tax). I created an expense account

Your response indicates that the HST is a tax from another country.

This forum deals exclusively with taxes for the United States.
