I paid rent to a landlord abroad and never issued NR4 slips, what now?
Start by separating two failures that usually arrive together: not withholding, and not reporting. The first leaves the payer liable for tax that should have been withheld on the rent. The second is a reporting default, charged by reference to the slip and the delay rather than to the tax. Deal with them in that order. We reconstruct what was paid or credited in each year, establish the amount that should have been withheld and remitted, and then issue the slips with the income and exemption codes those payments actually attract. Filing late with the right codes is a far better position than filing on time with the wrong ones, because the codes are what the non-resident's own claim rests on.
Does a late NR4 slip matter if the tax was already withheld and remitted?
Yes, because the slip is the only document the non-resident has. The income and exemption codes on it decide whether they can claim a treaty rate, whether a refund is available to them, and whether their home country will give credit for the Canadian tax paid. Until the slip exists, the tax has left the payer, reached the CRA, and is invisible to the person it was withheld from. We have seen payers treat a clean remittance record as the end of the obligation for several years while the payee was quietly paying tax twice on the same income. Remitting settles the payer's cash position; the slip is what makes the withholding usable.
Which is worse, filing an NR4 slip late or filing it with the wrong code?
In practice the wrong code does more damage. A late slip delays the payee's claim. A wrong code misdescribes the payment, so the rate applied looks correct on its face and no one questions it, sometimes for years. It is corrected with an amended slip, not with a position taken on a return, and that distinction matters: the amendment has to come from the payer, so a payee who spots the error cannot fix it themselves. When we take on an unfiled NR4 year we set the codes from the underlying payment stream rather than from whatever code the previous filings used.
We filed our own return late as well, is the NR4 penalty the same?
No. Separate regimes, calculated on different things. For the 2025 tax year the CRA's late-filing penalty on a return is 5 per cent of the balance owing plus 1 per cent of that balance for each full month the return is late, to a maximum of twelve months. Where the CRA has issued a demand to file and has already charged a late-filing penalty in any of the three preceding tax years, it is 10 per cent plus 2 per cent for each full month, to a maximum of twenty months. The penalty itself does not compound; interest on the unpaid balance compounds daily. Because that is a percentage of a balance owing, a year with nothing owing produces nothing. The slip default is charged by reference to the form and the delay instead, which is why an NR4 year in which the tax was fully remitted can still be expensive.
Can my non-resident payee still claim a refund if the slip is issued late?
Usually yes, and that is generally the reason to get the slips out rather than wait. The claim turns on what the payment was and what the slip says it was, so the income and exemption codes carry it. A late slip delays the claim; a wrong code can defeat it until the slip is amended. Time limits do apply to recovering over-withheld tax, and they run by year, so an old year and a recent one can sit in different positions. We check each open year against the payer's records before advising which of them is still worth pursuing.
Who has to issue the NR4 slips, the property manager or the owner?
The obligation follows whoever paid or credited the amount to the non-resident. That is a company, a fund, a property manager or an estate, depending on how the money actually moved. In our experience the argument is documentary rather than legal: the party that made the payment is the party that reports it, and a management agreement that says nothing about withholding does not shift that. Where a manager collects rent and forwards the balance abroad, we start from the bank record of who paid whom, then read the agreement, and the answer is rarely in doubt once both are on the table.
Which kind of investor income is most exposed to double taxation?
Dividends from a foreign corporation. They have already borne corporate tax, the source country withholds on payment, and your residence country taxes the receipt — three layers, only two of which a credit can reach. Interest and royalties carry the same source withholding without the corporate layer. This is why the withholding article and the paperwork that reduces it matter more for portfolio income than for salary. See dividends, interest and royalties articles.
Do dual citizens pay taxes in both countries?
Both countries can have a claim, but paying double taxes on the same dollar is the exception rather than the rule. The United States taxes its citizens wherever they live; Canada, India and most others tax on residence. So a dual citizen living in one of them often files in both — a resident return in one, a citizen return in the other — while the credit and exclusion rules mean the total is usually close to the higher of the two, not the sum. Filing twice is not paying twice. See two returns as a dual citizen.
