Yes. The summary is what reconciles the slips issued for a year to the tax actually remitted for that year, and a single slip still has to be reconciled. Volume changes nothing about the obligation; it only changes how long the work takes. The more useful question is whether the one slip and the remittances agree, because a single-slip year is where a mismatch is most often a simple timing difference, a payment posted to the wrong period or a remittance made under a second account. We reconcile the account before filing rather than filing and waiting to be asked about the difference.

Canadian withholding agents filing non-resident slips. The obligation is decided by facts rather than by tax owing, which is why a nil position does not remove it.
The rule on who files
Canadian withholding agents filing non-resident slips.

The exception worth knowing
The reconciliation is where under-remittance surfaces. The payer is liable for tax it should have withheld, so the summary is a control document rather than a formality.
How to get this moving
The full treatment — who it binds, the deadline, the penalty and the fixed fee — is on NR4 Summary — the return filed with the slips. If you already have an adviser, we will tell you what they should be asking rather than replacing them.

A first summary for a company that had been withholding for years
A manufacturer had been withholding on royalty payments to an overseas affiliate since the licence was signed and remitting monthly without fail. No summary had ever been filed, because the person who set up the remittances had treated them as a payment obligation rather than a reporting one. We reconstructed the account from the remittance history, prepared slips for the affiliate, and reconciled both to the monthly payments. The engagement produced a filed summary, a slip history the affiliate could use with its own tax authority, and a standing procedure tying each month's remittance to the code it belongs under.

A company paid the same overseas party both interest on a shareholder loan and a management charge. Both had been remitted through one withholding account and the internal record did not distinguish them, so the year would not reconcile. The order of work mattered: we split the payments by their source documents first, settled what each one was, and only then built the summary. Two streams were reported separately on the slips at the rates their own character supports. The engagement produced a reconciled year and a written note of how each payment type is to be coded in future.
Read how this one runsA property management company filing for owners abroad
A manager collected rent for a number of owners living outside Canada and remitted withholding for all of them through its own account. Slips had been issued inconsistently and no summary reconciled them. We built the year from the trust ledger, allocated each remittance to the owner it belonged to, and identified the owners for whom nothing had been withheld at all. Slips were issued per owner and the summary reconciled to the account. The engagement produced a filed reconciliation, a per-owner statement each owner could give their own adviser, and a monthly control the manager still uses.
Read how this one runsAn estate closing its withholding account after a final distribution
An executor had a final distribution to a beneficiary outside Canada and wanted the estate's affairs closed properly rather than simply stopped. The account had two years of activity. We reconciled both, separated the income component of each distribution from the capital, confirmed what had been withheld against what should have been, and filed the outstanding slips and summaries before asking that the account be closed. The engagement produced a complete filed record for the estate, a closed withholding account, and a memorandum for the executor recording how each distribution had been characterised.
Read how this one runsUntangling remittances made under the wrong account number
A company's withholding had been remitted for part of a year against an account belonging to a related entity. The slips were right, the money had been paid, and the year still would not reconcile because the payments were sitting somewhere else. We traced each remittance to its confirmation, established which entity had paid what, and had the misposted amounts reallocated before the summary was filed. The engagement produced a reconciled account for both companies, a filed summary that matched the slips issued, and a payment routine that names the account on the instruction itself.
Read how this one runsA nil year tested before the account was left dormant
A holding company expected to report nothing for a year: the overseas shareholder had taken no dividend and the intercompany loan had been repaid. Rather than accept that, we read the accounts for amounts credited rather than paid, which is where a nil year usually turns out not to be nil. A year-end accrual in favour of the shareholder had been booked and never paid. The engagement produced a slip and summary for that amount, a corrected view of what the account owed, and a decision to keep the account open rather than close it prematurely.

Residence in India and citizenship in the United States produce two annual returns for one income. The order decides the credit, and the Indian financial year and the US calendar year have to be reconciled before either is prepared.
Read how this one runsA Canadian Property Sale Held Up for a Clearance Certificate
When a non-resident sells Canadian real estate the purchaser must hold back a portion of the price until the seller produces a certificate. The file applies for it on the correct basis and works to the closing date, because the holdback is released against the certificate, not against the sale.

Foreign property income and sales are taxed in both countries by default; Section 216, FIRPTA and treaty credits are the standing toolkit.
Property is taxed where it sits, which is the one rule no treaty overrides. What the treaty does decide is the credit, the rate on the rent and what happens on the sale — and the clearance certificate on a disposition is applied for before closing, not after the buyer has already held the money back.

The follow-up questions on Form NR4 Summary
Because remitting and reporting answer different questions. The remittances show money reaching the CRA; the slips show who it was withheld from and on what kind of payment; the summary is the document that proves those two sets of figures describe the same year. It is a control document rather than a formality, and the reconciliation is the point of it. In our experience that is also where under-remittance first becomes visible to the payer itself, which is an argument for preparing it properly rather than transcribing the slip totals and signing.
Someone else can prepare and submit it, and often does. What cannot be delegated is the liability behind it. The payer is liable for tax it should have withheld, so the figures on the summary are the payer's figures whoever types them. That has a practical consequence worth acting on: the person preparing the summary usually has the slips and the remittance record, but not the contracts that decide what each payment was. We ask for both, because a summary that reconciles perfectly to slips carrying the wrong income codes reconciles to the wrong answer.
Find out which side is wrong before you file anything. A difference has a small number of ordinary causes: a payment credited but not paid, a remittance posted to the wrong period or the wrong account, a payee treated as resident for part of the year, or withholding applied at a rate the payment did not attract. Each is fixed differently, and only the last is a real under-remittance. We work the difference back to individual payments, then either correct the slips or quantify and settle the shortfall. Filing a summary that carries an unexplained difference invites the question you have not yet answered.
The obligation is decided by the facts of the year rather than by tax owing, so a nil position does not remove a filing requirement on its own, and an open withholding account with nothing to report is a position worth settling deliberately rather than by silence. Two things are worth separating: whether there really were no reportable amounts, and whether the account should stay open at all. Amounts credited rather than paid are the usual surprise in a year the payer thinks is nil. We test that first, then advise on filing or on closing the account.
It can be done alongside them, but it should not be treated as one of them. Payroll reporting describes employment, and non-resident slips describe rent, dividends, interest, royalties and pensions paid to people outside Canada, so the codes, the rates and the underlying documents are all different. What we see when the two are handled by the same process is a non-resident stream reported on whichever slip the software offered. We keep the reconciliation separate: the summary is built from the payment stream and the remittance record for that account, and nothing else.
By the route that country provides, and it is rarely automatic. Where an elective return is available — on rent or pension income, for instance — filing it recomputes the tax on net income and refunds the difference. Where it is not, you file a refund claim with the withholding authority, supported by evidence of your residence and entitlement to the treaty rate. Both take time, which is why fixing the rate before payment is worth more. See withholding refund and recovery.
On your residence-country return, as a disposition, with proceeds and cost base converted at the rates for their own dates. Separately, the country where the property sits may require its own return and may hold back tax at closing until a clearance or certificate is issued — Canada does this for a non-resident vendor, and the United States withholds on a foreign seller of US real property. Those steps have their own deadlines, often before closing. See clearance certificates on a property sale.
