Remitting Tax on the Construction or Renovation of a Residential Complex (Self-Supply)

You generally have to remit GST/HST and QST in the following situations:

You build a residential complex on land you own.
You build or substantially renovate such a complex to lease all or part of it or to use it as your residence.
You build an addition (for example, a new floor or wing) to a residential complex to lease all or part of it or to use it as your residence.

In such a case, you, the builder, are considered to be the seller and the recipient of the residential complex. You are therefore deemed to have made a self-supply. You must therefore remit the tax that you are deemed to have collected as the seller and paid as the recipient, which is calculated on the fair market value (FMV) of the complex or addition.

Note that these “self-supply rules” apply only to new or substantially renovated residential complexes.

If any of the situations covered on the pages listed below apply to you, you may have different obligations for remitting tax on the construction or substantial renovation of a residential complex:
