What Happens If I Don't File an NR4?
If you paid rent, interest, dividends, pension, or other amounts to a non-resident, you were required to withhold tax and file an NR4. Missing that filing exposes you, the Canadian payer, to penalties, interest, and personal liability for the tax that should have been withheld. Here is exactly what happens, and how to fix it.
Quick Answer
If you do not file a required NR4, the CRA can charge a late-filing penalty based on the number of slips, daily compound interest, and can hold you, the Canadian payer, personally liable for the non-resident tax you failed to withhold and remit, plus a separate penalty for not withholding. The obligation sits with the payer, not the non-resident.
What the NR4 Is and Why the Payer Carries the Risk
The NR4 is the information return a Canadian payer files to report amounts paid or credited to a non-resident of Canada, along with the tax withheld on those amounts. Rent to a non-resident landlord, interest, dividends, pensions, royalties, and management fees are common triggers. The key point that catches people out is that the obligation to withhold, remit, and file rests with the Canadian payer or agent, not the non-resident who received the money. When the filing is missed, it is the payer the CRA pursues. We prepare NR4 returns and non-resident withholding filings for payers, agents, and property managers across Ontario.
| What People Assume | What the Rules Actually Say |
|---|---|
| The non-resident handles their own tax | The Canadian payer must withhold, remit, and file the NR4 |
| No slip needed if tax was withheld | An NR4 slip and summary are required even when tax was withheld correctly |
| Small amounts can be ignored | Reportable amounts must be filed regardless of size |
| Only the withholding tax is at risk | The payer can be personally liable for tax not withheld, plus penalties |
What Happens If You Don't File the NR4
Not filing does not shift the problem to the non-resident. It leaves the exposure with you as the payer, and it grows on three fronts at once: the late slips, the tax that should have been withheld, and the interest running on both.
| Consequence | What It Means for You |
|---|---|
| Late-filing penalty on the slips | A penalty based on the number of NR4 slips filed late, rising with how many slips and how late they are, with a set minimum and maximum per return. |
| Failure to withhold | If you did not withhold the required tax, you can be assessed for the full amount you should have withheld, as if you had withheld it. |
| Penalty for not remitting | A separate penalty applies on amounts you were required to withhold and remit but did not, on top of the tax itself. |
| Daily compound interest | Interest accrues on unremitted tax and penalties, compounding daily at the CRA's prescribed rate, which changes quarterly. |
| Personal payer liability | The payer, not the non-resident, is on the hook, so the cost lands on you even though the income belonged to someone else. |
You can be assessed for tax you never withheld. This is the part that surprises most payers. If you paid a non-resident and did not hold back the required tax, the CRA can assess you for that full withholding amount, plus a penalty and interest, and then it is on you to try to recover it from the non-resident. Missing the NR4 does not just cost a slip penalty, it can make you personally responsible for the tax itself.
Who Actually Has to File an NR4
The obligation reaches further than most Canadian payers realize. If any of these describe you, an NR4 filing obligation likely exists and should be confirmed for each year.
| Situation | Why an NR4 May Be Required |
|---|---|
| You rent a Canadian property to a non-resident, or manage one | Rent paid or credited to a non-resident landlord is subject to withholding and NR4 reporting. |
| A Canadian corporation pays dividends to a non-resident shareholder | Dividends to non-residents require withholding and an NR4 slip. |
| You pay interest, royalties, or management fees to a non-resident | These payments are commonly reportable and subject to withholding. |
| A plan or payer sends pension or annuity amounts abroad | Pension, RRSP, RRIF, and annuity payments to non-residents are reportable. |
| You act as agent for a non-resident receiving Canadian income | An agent or property manager takes on the withholding and filing duty. |
The tax treaty may lower the rate, but it does not remove the filing. A tax treaty between Canada and the non-resident's country can reduce the withholding rate below the standard 25%, but you still have to withhold at the correct treaty rate and still have to file the NR4. Applying a treaty rate without the paperwork to support it is a common and costly mistake. Know Your Exact Fee →
How to Fix a Missed NR4
If you are behind, the situation is usually fixable, and acting before the CRA contacts you preserves the most options. The right path depends on whether the tax was actually withheld, how many years are involved, and how much is at stake.
| Your Situation | The Likely Fix |
|---|---|
| You withheld the tax but never filed the slips | Prepare and file the outstanding NR4 slips and summary now to stop the slip penalty growing. |
| You did not withhold at all | Determine the amount that should have been withheld, remit it, and file, ideally with a relief request given the exposure. |
| Several years are outstanding | File the years in sequence; a taxpayer relief request may reduce penalties and interest where the facts support it. |
| The CRA has not contacted you yet | A voluntary disclosure may relieve penalties on prior years if you come forward first and qualify. |
Come forward before the CRA does. As with other returns, applying through the Voluntary Disclosures Program or requesting relief before the CRA raises the issue generally gives more options than waiting to be assessed. With payer liability for unwithheld tax on the table, the cost of leaving an NR4 unfiled is real, and it rises with every year that passes.
Case Study: A Landlord Who Did Not Know the Tenant's Rent Was Reportable
A Canadian property owner moved abroad and became a non-resident, and a family member collected the rent and deposited it without withholding any tax or filing anything, assuming nothing was required. Because rent paid to a non-resident landlord is subject to 25% withholding and NR4 reporting, the CRA could assess the person collecting the rent, as agent, for the tax that should have been held back across several years, plus penalties and interest. We confirmed the position, calculated the correct withholding, filed the outstanding NR4 returns, and applied for relief before the CRA had raised the issue. The filings were brought current and the exposure was substantially reduced. We estimate the cleanup addressed roughly $18,000 of withholding that had been overlooked. The figures are illustrative of the kind of outcome we see, not a specific client file.
