Some Canadians living abroad remit substantially more non-resident tax during the year than their eventual Canadian rental-income tax calculation may require.
This can happen because, under the default rules, tax is generally withheld at 25% of gross Canadian rental income — before rental expenses are considered.
Form NR6 provides an alternative.
When the CRA approves an NR6, the non-resident's Canadian agent can generally withhold 25% based on estimated net rental income rather than gross rental income.
For owners with significant eligible rental expenses, that difference can have a substantial effect on monthly cash flow.
How the default non-resident withholding works
A non-resident earning rental income from Canadian real property is generally subject to 25% withholding on the gross rental income paid or credited to them.
That withholding occurs before expenses such as Property Management fees, insurance, eligible utilities, repairs, and deductible financing costs are considered.
For example, suppose a property generates $2,500 per month in gross rent.
Under the standard gross-withholding approach:
25% of $2,500 = $625
The agent would generally withhold and remit $625 for that month's rental income.
But gross rent and net rental income can be very different numbers.
How an approved NR6 can change the calculation
Form NR6 allows a non-resident owner and their Canadian agent to ask the CRA for approval to base withholding on estimated net rental income instead.
Suppose that same $2,500 rental property has enough eligible expenses that its estimated net rental income for the month is $300.
If the NR6 has been approved and the withholding calculation is based on that $300 net amount:
25% of $300 = $75
In this simplified example, the difference between withholding $625 on gross rent and $75 on estimated net rental income is $550 for that month.
That does not mean the owner's final Canadian income tax for the month is $75.
NR6 affects the amount withheld and remitted during the year. The owner's actual income, allowable expenses, and resulting tax are reconciled through the required Section 216 return.

What happens if you don't file an NR6?
Not filing an NR6 does not necessarily mean the 25% withheld on gross rent is permanently the owner's final tax cost.
Under the CRA's Section 216 rules , a non-resident may generally choose to file a Section 216 return after the year ends and calculate Canadian tax on net rental income.
If the resulting tax is less than the amount already withheld, the owner may be entitled to a refund.
If the owner does not make a Section 216 election, the 25% non-resident tax withheld on gross rental income is generally treated as the final Canadian tax obligation on that rental income.
NR6 changes the timing of the cash flow
The major practical difference between the two approaches is when the money leaves the property.
Without an approved NR6
The agent generally withholds 25% of gross rental income throughout the year.
The non-resident can later choose to file a Section 216 return and may recover some of that withholding if the tax calculated on net rental income is lower.
With an approved NR6
The agent can generally withhold 25% based on estimated net rental income after the CRA approves the form.
This can leave more of the property's cash flow available during the year rather than requiring the owner to wait until after filing a tax return to potentially recover excess withholding.
The trade-off is that Form NR6 is an undertaking to file a Section 216 return.
For an individual with an approved NR6, the Section 216 return generally must be filed by June 30 of the following year, even if there is no tax payable or the property generated a net rental loss.
If the required return is not filed by the applicable deadline, the NR6 election can become invalid and the owner may become subject to non-resident tax based on gross rental income.
When should Form NR6 be filed?
The CRA recommends submitting Form NR6 on or before January 1 of the rental year or before the first rental payment is due.
Filing early is important because the agent must continue withholding tax based on gross rental income until the CRA approves the NR6 in writing.
However, an NR6 can also be submitted later in the year.
If the CRA receives and approves a later NR6, withholding based on net rental income can generally take effect from the first day of the month in which the CRA received the form. Rental income paid or credited before that effective date remains subject to gross withholding.
That is why owners who expect to use NR6 are generally better served by dealing with it before the rental year begins rather than waiting until several months of gross withholding have already occurred.
The Section 216 return still matters
NR6 and Section 216 perform different functions.
The NR6 affects withholding during the year.
The Section 216 return is where the owner reports Canadian rental income and eligible expenses and calculates the actual Canadian tax applicable under the election.
An owner with an approved NR6 should therefore treat the Section 216 filing deadline as part of the same process rather than as an unrelated year-end tax task.
Non-resident owners also need appropriate records of rental income, expenses, withholding, and NR4 reporting.
This is why non-resident Property Management and tax administration involves more than simply collecting rent from a Canadian property.
Watch: How NR6 affects non-resident rental cash flow
The video below provides an overview of how NR6 works, why gross withholding can affect monthly cash flow, and how the process connects with Section 216 reporting.
The bottom line
Form NR6 does not reduce tax simply because the form has been filed.
Its main cash-flow advantage is that, once approved, it can allow withholding to be based on estimated net rental income rather than gross rental income.
For a property with meaningful eligible expenses, the difference can be significant.
But that benefit comes with additional filing obligations, including the requirement to complete the applicable Section 216 return on time.
Non-resident owners should therefore think about NR6, withholding, expense records, NR4 reporting, and the Section 216 return as parts of the same annual tax-administration process.
Frequently Asked Questions
What happens if a non-resident landlord doesn't file an NR6?
Without an approved NR6, the agent generally withholds 25% of gross Canadian rental income rather than net rental income. The non-resident may later choose to file a Section 216 return and potentially recover part of the amount withheld if the resulting Canadian tax is lower.
When should Form NR6 be filed?
The CRA recommends filing Form NR6 on or before January 1 of the rental year or before the first rental payment is due. The CRA can accept the form later in the year, but withholding based on net rental income does not retroactively replace gross withholding on earlier rental payments.
Can withholding on net rental income begin as soon as I send the NR6?
No. The Canadian agent must continue withholding based on gross rental income until the CRA approves Form NR6 in writing. Once approved, the effective date for net-income withholding is generally tied to when the CRA received the form.
Do I have to file a Canadian tax return if my NR6 is approved?
Yes. Form NR6 is an undertaking to file a Section 216 return. For an individual, an approved NR6 generally requires the Section 216 return to be filed by June 30 of the following year, even if there is no tax owing or the property produced a net rental loss.
Does NR6 mean I only pay 25% tax on my rental profit?
Not exactly. An approved NR6 allows the agent to calculate non-resident withholding during the year using estimated net rental income instead of gross rental income. The owner's actual Canadian tax position is determined when the Section 216 return is filed.
