You should send us Form NR6 on or before January 1, of each year, or before the first rental payment is due. Your agent must continue to withhold non-resident tax on the gross rental income until we approve, in writing, your Form NR6. ...
After we approve your Form NR6, your agent can withhold non-resident tax at the rate of 25% on your net rental income (that is the amount of rental income available after the rental expenses have been paid). ...
If we approved your Form NR6 for the year and you do not file your section 216 return by the due date, you will be subject to non-resident tax on your gross rental income. If the correct amount of this tax was not withheld at source, we will issue a non-resident tax assessment to your agent. ...
You cannot use a loss you report on your section 216 return to reduce income on another Canadian return for 2015 or any prior or future tax year. As well, you cannot apply this loss to a section 216 return for any prior or future year.
