Ready to file a UHT return

Online check list

If you have an amount owing, find out how to make a payment to the Canada Revenue Agency.

Should your underused housing tax return be subject to any failure to file penalty under subsection 47(1) or 47(2) of the UHTA, all dates and times will be determined in Eastern Time. Any returns filed after midnight EDT/EST of the filing due date will be considered late.

Please note that your secure filing session will expire after 35 minutes of inactivity.

Account information

You will be asked to provide the following information:

  • your Individual Tax Number (ITN) or Social Insurance Number (SIN) or Business Number (BN-RU);
  • the calendar year for which you are filing your return;
  • the address with postal code of the residential property;
  • Taxable and fair market value (if applicable) of the property; and
  • assigned Digital Access Code or EFILE On-Line number and password.

Confirmation of receipt

After you successfully submit your return, you will receive a confirmation number. This confirmation number is your proof that the Canada Revenue Agency (CRA) has received your information. Print the page with your confirmation number and keep it with your records. Do not mail paper copies of returns that you have submitted electronically.

After we've processed your return, we may have to contact you for more information, so keep all supporting documents for six years. This applies whether you file on paper or electronically.
