If you are a person who has bought a new or substantially renovated mobile home (including a modular home) or a new or substantially renovated floating home for use as your (or your relation’s) primary place of residence, you may be eligible for a new housing rebate for some of the GST/HST paid.
In most cases, you do not have to submit supporting documents with your GST/HST new housing rebate application. However, you do have to send invoices with your worksheet if the vendor did not charge the GST/HST on the invoice (photocopies of these invoices will be accepted). The CRA may contact you to ask for proof of occupancy.
Maintain a copy of the filled-out forms. In case the CRA wants to see them, you will have to retain all your original invoices and records you used to fill out the forms for six years. Only original invoices are permissible in the name of the claimant or the co-owners. Without the original invoices, the CRA does not accept photocopies, credit card or Interac slips, or account statements. Estimates or quotes are not recognized by the CRA as proof. They will be returned if the CRA asks you to submit your invoices.
