Kept a Rental Property in Canada? Section 216, NR6, and NR4 — the Non-Resident Landlord's Rulebook

It's one of the most common moves in the cross-border playbook: you relocate to the U.S. — new job, new life — but you keep the Toronto condo or the Vancouver townhouse and rent it out. Solid asset, rising market, tenant covers the mortgage. What almost nobody explains at the closing of that decision: the day you became a non-resident of Canada, the tax rules on that rental income changed completely — and the default version of the new rules is brutal.

Here's the whole system — the 25% problem, and the three-form machinery (NR6, Section 216, NR4) that fixes it.

The default: 25% of your gross rent, off the top

Once you're a non-resident, Canadian rental income stops being ordinary income you report on a regular return. It falls under Canada's non-resident withholding regime: 25% of the gross rent must be withheld and sent to the CRA — remitted by the 15th of the month after the rent was received.

Read that again: gross. Not profit — the full rent cheque, before the mortgage interest, property tax, condo fees, insurance, repairs, or the property manager's cut. A condo renting for $3,000/month owes $750/month in withholding even if, after expenses, the property barely breaks even. For most leveraged rentals, 25% of gross is wildly more than any fair tax on the actual profit.

And the obligation to withhold legally falls on the payer — your property manager, or your tenant if there's no manager. In practice, absent landlords with no agent simply have no one withholding, which doesn't make the tax disappear; it makes it a growing liability with interest, waiting to surface — often years later, when you sell the property and the CRA looks at the file.

NR6: the form that shrinks the withholding to something sane

The fix at the front of the system is Form NR6. It's an undertaking filed with the CRA — by you and a Canadian agent who agrees to be responsible for the withholding — that lets the 25% be calculated on your **expected net income** instead of gross rent.

For a property where expenses eat most of the rent, that's the difference between $750/month and a small fraction of it — or nothing, if the property runs at a loss on paper.

Three things to get right:

• Timing. The NR6 must be filed and approved before the first rent payment it's meant to cover — practically, before January 1 for a calendar year, or before the first payment when a new tenancy starts. File late and the months already paid stay at 25%-of-gross.
• The agent is real. A Canadian-resident agent (a property manager, or a trusted Canadian individual willing to take it on) signs on the line and becomes personally responsible for remitting. This isn't a formality — it's why some managers charge for the role, and why "my cousin will sign it" deserves a serious conversation with the cousin.
• The string attached. Filing an NR6 commits you to filing a Section 216 return for that year — on a tighter deadline. Which brings us to the centerpiece.

Section 216: the election that taxes your actual profit

The Section 216 return is an elective Canadian tax return for non-residents with rental income. Instead of letting the flat withholding on rent be the final tax, you elect to report the rental operation like a business: gross rents minus actual expenses, with the net income taxed at ordinary graduated rates.

This election allows you to pay tax on your net rental income or timber royalty income instead of the gross amount.

For nearly every leveraged rental property, the Section 216 result is far below 25% of gross — so the return typically generates a refund of over-withheld tax. It's not an obligation so much as the mechanism by which you get your money back.

The deadlines are where people stumble, because they depend on whether an NR6 was filed:

• No NR6 (you withheld 25% of gross all year): you have up to two years after the end of the year to file the Section 216 return and claim the refund. Miss that window and the over-withheld tax is simply gone.
• With an NR6: the Section 216 return is mandatory and due within six months of year-end — June 30 for a calendar year. Miss it and the CRA can retroactively void the NR6 arrangement and assess the full 25%-of-gross against your agent, which is a spectacular way to lose both money and the relationship with whoever signed for you.

One more planning note: expenses only help if they're documented. Non-resident landlords need the same disciplined books a Canadian landlord keeps — mortgage interest statements, condo fee records, repair invoices — except theirs get read by two tax systems, not one.

NR4: the slip that reports it all

The third piece is administrative but mandatory: the NR4 slip and summary, filed by whoever withheld (your agent or property manager) by March 31, reporting the gross amounts paid to you and the tax remitted. Think of it as the non-resident's T4 for this income: it's what the CRA matches everything against, and it's the document your Section 216 return reconciles to. If you self-manage through a Canadian agent, making sure the NR4 actually gets filed is part of the annual rhythm — missing slips carry penalties and orphan the whole paper trail.

Meanwhile, the U.S. wants the same income reported

Here's the part the Canadian forms don't mention: as a U.S. tax resident, that Canadian rental goes on your U.S. return too — worldwide income. The relief is the foreign tax credit for the Canadian tax actually paid (your final Section 216 liability, not the temporary withholding). But the two countries compute rental income differently — most notably, the U.S. requires depreciation on a rental while Canada's CCA is optional and often skipped by non-residents — so the two nets rarely match, and the credit math needs both returns done by someone who sees both. Done in isolation, the classic failures are double-taxed income or a U.S. return that never mentioned the condo at all. (If the property sits alongside Canadian bank accounts you kept, the FBAR reporting stack is running too.)

And when you eventually sell…

A preview, because it surprises everyone: selling Canadian real estate as a non-resident triggers its own regime — a Section 116 clearance certificate, withholding on the sale proceeds until it's issued, and capital gains filings in both countries. The rental years and the sale are one continuous file; keeping the 216 returns clean along the way is precisely what makes the exit smooth.

The annual rhythm, in one paragraph

Done properly, the year looks like this: NR6 filed and approved before the rent year starts; the agent withholds monthly on expected net and remits by the 15th; the NR4 goes in by March 31; the Section 216 return files by June 30 and trues everything up; and the same numbers, converted and adjusted, land on your U.S. return with a foreign tax credit doing the reconciliation. Miss any link and the system defaults back to its ugly setting: 25% of gross, someone personally liable, refunds expiring.
