When Is the NR4 Filing Deadline?

The NR4 reports amounts paid or credited to non-residents of Canada, and the deadline is not the one most people assume. Miss it, and the penalty starts per slip and climbs with every day late. Here is exactly when the NR4 is due, who must file it, and what it costs to be late.

Quick Answer

The NR4 return is due by the last day of March following the calendar year the amounts were paid or credited to a non-resident. If your business has a fiscal year that is a trust or estate, the return is due within 90 days of the end of that year instead. Filing late triggers a per-slip penalty that grows with each day, so the March 31 date is the one to protect.

The Honest Answer: March 31 Is the Date That Matters Most

For most payers, the NR4 return, both the slips and the summary, must reach the CRA by March 31 of the year following the one in which the income was paid or credited to the non-resident. That is the deadline the majority of businesses and individuals need to hold. Trusts and estates work on a different clock, filing within 90 days of their year-end. The withholding tax itself is due earlier, so the March deadline is for reporting, not for the money. We handle NR4 filing and non-resident tax compliance for businesses and property owners across Ontario and Canada.

Who Is FilingNR4 Return Deadline
Most businesses and individualsMarch 31 following the calendar year
Trusts and estatesWithin 90 days of the trust or estate year-end
Rent paid to a non-resident landlordMarch 31 following the calendar year
Withholding tax remittanceBy the 15th of the month after the amount was paid
Slips to the non-resident recipientBy the March 31 filing deadline

Who Actually Has to File an NR4

The NR4 is not only for large companies. Anyone who pays or credits certain amounts to a non-resident of Canada may have to file, and many are caught out because they never thought of themselves as a payer. These are the common situations that create an NR4 obligation.

Payment to a Non-ResidentNR4 Filing Required
Rent on Canadian property to a non-resident ownerYes, by the agent or payer.
Dividends, interest, or royaltiesYes, where paid or credited to a non-resident.
Pension, annuity, or retirement incomeYes, where paid to a non-resident recipient.
Management or estate distributionsYes, where the recipient is a non-resident.
Payments entirely between residents of CanadaNo NR4 obligation.

The rent-to-a-non-resident-landlord case is the one most people miss. If you manage or pay rent on a Canadian property owned by someone living abroad, you are generally required to withhold tax and file an NR4, even if you are an individual acting informally. The obligation sits with the Canadian payer or agent, not the owner overseas. Know Your Exact Fee →

What Being Late Actually Costs

A late NR4 is not a single flat fee. The penalty is calculated per slip and grows with the number of days you are late, up to a maximum for that slip type, and it sits on top of any withholding tax and interest already owing. These are the consequences that add up fastest.

ConsequenceWhat It Means for You
Late-filing penalty per slipA daily penalty scaling with the number of slips and days late, up to a maximum for the slip type.
Interest on late withholdingIf tax was withheld late or not remitted, interest compounds daily until it is paid.
Penalty for late remittanceRemitting the withheld tax after the monthly deadline carries its own separate penalty.
Failure-to-withhold liabilityIf you did not withhold at all, the payer can be held liable for the tax that should have been withheld.
Wider non-resident reviewA missed NR4 can prompt the CRA to examine your other non-resident payments and treaty positions.

The withholding deadline comes before the filing deadline. Many payers focus on March 31 and forget the tax itself must generally be remitted by the 15th of the month after the amount was paid or credited. Missing that earlier remittance date creates penalties and interest well before the NR4 slips are even due, so please treat the two deadlines as separate obligations.

Getting the NR4 Right, Not Just On Time

Filing on time is only half the task. The NR4 also has to report the correct income code, the correct country, and the correct withholding rate, often reduced by a tax treaty. Getting those wrong causes rejections and reassessments even when the return arrives on time. This is where a CPA earns the fee.

Getting It RightWhy It Matters
Correct income and exemption codesThe NR4 uses specific codes for each type of income, and the wrong code causes errors and reassessment.
Correct treaty withholding rateA tax treaty can reduce the standard withholding rate, but only if applied and documented correctly.
Correct recipient country and detailsThe non-resident's country of residence drives the rate, so accurate details are essential.
Matching remittance to slipsThe tax remitted through the year must reconcile to what the NR4 slips report.

Withholding at the wrong rate is as costly as filing late. Payers often apply the flat statutory rate when a treaty allows a lower one, or apply a treaty rate the recipient does not actually qualify for. Over-withholding ties up the non-resident's money, while under-withholding leaves the payer liable for the shortfall. The rate has to be right for the recipient's country and income type, not assumed.

Case Study: A Non-Resident Landlord and Three Years of Missed NR4s

An individual managing a Canadian rental property for a family member who had moved abroad had collected and forwarded rent for three years without withholding tax or filing a single NR4, unaware the obligation sat with them as the Canadian payer. When the owner planned to sell, the gap surfaced, with penalties and interest building across every missed slip and remittance. We reconstructed the payments, calculated the correct withholding under the applicable treaty, filed the outstanding NR4 returns, and submitted a relief request given the failure was genuine and brought forward voluntarily. We estimate the approach saved roughly $7,400 against a straight assessment. The figures are illustrative of the kind of outcome we see, not a specific client file.

Frequently Asked Questions

When is the NR4 filing deadline?
For most payers the NR4 return is due by March 31 of the year following the calendar year the amounts were paid or credited to a non-resident. Trusts and estates file within 90 days of their year-end. The withholding tax itself is due earlier, on the 15th of the month after payment.
What is an NR4?
The NR4 is the return used to report amounts paid or credited to non-residents of Canada that are subject to withholding tax, such as rent, dividends, interest, royalties, and pensions. It includes both the individual slips and a summary sent to the CRA.
Who has to file an NR4?
Any Canadian resident or agent who pays or credits certain amounts to a non-resident. That includes companies paying dividends or interest, and individuals or agents paying rent on Canadian property to an owner living abroad.
What is the deadline for a trust or estate NR4?
A trust or estate files its NR4 return within 90 days of the end of its tax year, rather than by the March 31 date used by most other payers. The exact date therefore depends on the trust or estate year-end.
When is the withholding tax due, as opposed to the NR4 return?
The withholding tax is generally due by the 15th day of the month following the month the amount was paid or credited. This is separate from and earlier than the March 31 filing deadline for the NR4 slips and summary.
What is the penalty for filing an NR4 late?
It is a daily penalty that scales with the number of slips and the number of days late, up to a maximum for that slip type. Because it is calculated per slip, a payer with several non-resident recipients can face a larger charge than expected.
Do I file an NR4 for rent paid to a non-resident landlord?
Yes. If you pay or manage rent on Canadian property owned by a non-resident, you generally must withhold tax and file an NR4. The obligation sits with the Canadian payer or agent, even where you are acting informally for family.
What is the standard withholding rate on payments to non-residents?
The statutory rate is 25 percent on many types of Canadian-source income paid to non-residents. A tax treaty between Canada and the recipient's country can reduce that rate, but only when it is applied and documented correctly.
Can a tax treaty reduce the NR4 withholding rate?
Yes. Treaties often lower the rate on dividends, interest, and royalties for residents of the treaty country. The reduced rate applies only where the recipient qualifies and the position is supported, so it should be confirmed rather than assumed.
What happens if I don't withhold at all?
The Canadian payer can be held personally liable for the tax that should have been withheld, plus penalties and interest. Failing to withhold is treated seriously because the CRA has limited ability to collect from the non-resident directly.
Can I file an NR4 late?
Yes, and you should as soon as possible. Penalties keep accruing until the return is filed, so filing late is always better than not filing. Coming forward voluntarily, before the CRA raises it, also puts you in a stronger position for relief.
Can the CRA waive the NR4 penalty?
It can, where the failure is genuine and you correct it voluntarily, often through the Voluntary Disclosures Program or taxpayer relief provisions. Relief is never guaranteed, but a proactive, well-documented correction gives the best chance of it.
What is the difference between an NR4 and a Section 216 return?
The NR4 is the payer's reporting of amounts paid to a non-resident. A Section 216 return is filed by the non-resident owner to report rental income on a net basis, often reducing the tax compared with the flat withholding. They serve different purposes and can both apply.
What income codes go on an NR4?
The NR4 uses specific codes to identify the type of income and any exemption applied, such as rent, dividends, interest, or pension. Using the wrong code causes errors and reassessment, so the coding needs to match the actual payment.
Do I need a non-resident tax account to file?
Yes. NR4 amounts are reported and remitted through a non-resident tax account with the CRA, which is separate from your regular payroll or corporate accounts. Setting it up correctly before the first remittance keeps the filing clean.
What records should I keep for NR4 filing?
Keep records of each payment, the recipient's country and details, the rate applied, any treaty support, and proof of remittance. Clean records make the slips accurate and are essential support if the CRA questions a rate or a payment.
Do I still file an NR4 if the amount was small?
Generally yes, where the payment is a reportable amount to a non-resident. The obligation is driven by the type of payment and the recipient's status, not simply by size, so small payments can still require a slip.
Can I get a refund if I over-withheld on an NR4?
Often yes. Where too much was withheld, the non-resident may recover the excess by filing the appropriate return, such as a Section 216 return for rental income. Getting the rate right at source is cleaner, but over-withholding can usually be corrected.
What happens if I keep ignoring the NR4 requirement?
Penalties and interest keep building, the payer's liability for unwithheld tax grows, and the risk of a wider CRA review rises. A small missed slip can become a significant assessment, so continued inaction is the most expensive path.
How much does it cost to file an NR4?
We quote an AFFORDABLE flat fee up front based on the number of recipients and the state of your records, confirmed before we start. All fees include HST, and there is no hourly billing. Know Your Exact Fee →
Can you file several years of missed NR4 returns at once?
Yes. We can reconstruct the payments, calculate the correct withholding, prepare the outstanding returns across each year, file them, and where appropriate submit a relief request. Bringing several years current in one process is usually far cheaper than being assessed.
Does a non-resident recipient need a Canadian tax number?
In many cases the non-resident needs an identification number for the NR4, and the correct number affects how the slip is processed. Where one is missing, the recipient may need to apply for it, which is worth arranging before the deadline.
Is the NR4 the same as a T4 or T5?
No. The T4 reports employment income and the T5 reports investment income, both for residents. The NR4 is specifically for amounts paid or credited to non-residents. Using the wrong slip creates its own problems, so the recipient's residency drives the choice.
Do I file an NR4 for a non-resident contractor I paid?
Payments to non-residents for services performed in Canada can carry their own withholding and reporting, sometimes under different rules than the NR4. The treatment depends on the type of payment and where the work was done, so it should be confirmed.
Can you take over my non-resident bookkeeping too?
Yes. We can handle the bookkeeping alongside the tax filing and NR4 slips so non-resident payments, rates, and remittances are tracked cleanly through the year, which keeps filing accurate and any CRA question straightforward.
Do you handle both the NR4 and the non-resident's return?
Yes. The payer's NR4 and the non-resident's own return, such as a Section 216, are connected through the same income. We can handle both so the withholding, the slips, and the recipient's filing line up correctly.
Will an accountant help me avoid these penalties going forward?
Yes. Once your non-resident account, withholding rates, and remittance schedule are set up properly, the slips get filed on time every year and the penalty risk disappears. The value is in never facing the charge again, not just fixing it once.
What if the non-resident lives in a country with no tax treaty?
Where no treaty applies, the standard statutory withholding rate generally governs, with no treaty reduction available. Confirming whether a treaty exists and applies is one of the first steps, since it directly sets the rate you must withhold.
How do I pay your fees?
Payment is by Interac e-Transfer to info@gondaliyacpa.ca. Auto-deposit is enabled, so no security question is needed.
