How does the 25% non-resident withholding on Canadian rental income work?

Who actually has to withhold the tax

Under Part XIII of the Income Tax Act, the obligation to withhold falls on whoever pays or credits the rent to a non-resident landlord, not on the landlord themselves. In practice that is the tenant, if they are paying rent directly to someone living abroad, or a Canadian property manager acting as the landlord's agent. The amount to withhold is 25% of the gross rent, before any deduction for mortgage interest, property tax, repairs, or a management fee, since the withholding is meant to be a rough proxy for tax owing, not a precise calculation.

Many individual tenants have no idea this obligation exists, which is one reason non-resident landlords so often route the rental through a property manager: the manager is used to the mechanics and can take on the withholding and remittance responsibility on the owner's behalf.

The remittance deadline and what happens if it is missed

The withheld amount has to be remitted to the CRA by the 15th day of the month following the month the rent was paid or credited, using the non-resident's account information so the payment is matched correctly. If the payer fails to withhold or remit on time, the CRA can hold them personally liable for the tax that should have been withheld, along with penalties and interest, even though the money was owed by someone else. This is the practical reason tenants and small landlords alike are better served by having a professional handle the remittance rather than treating it as an afterthought each month.

The NR4 slip

Whoever withholds the tax also has an annual reporting obligation. By March 31 of the year following the calendar year the rent was paid, the payer must issue an NR4 slip to the landlord and file a copy with the CRA, showing the gross rent paid and the tax withheld. This slip is the non-resident's record of what was withheld and is needed if they later file a section 216 return to reconcile the withholding against their actual net-income tax liability.

Reducing the withholding with an NR6

Because 25% of gross rent is often more than the actual tax owed once expenses are considered, a non-resident landlord can file Form NR6, an undertaking to file a section 216 return, before the tax year starts or before the first rental payment on a new property. Once approved, the payer withholds tax on an estimated net income figure agreed with the CRA instead of the full gross rent, which keeps more cash flowing to the landlord through the year. The tradeoff is a firm commitment to file the section 216 return within six months of the year-end; we walk through that election in full in what is a section 216 return.

Recovering the excess without an NR6

If no NR6 was in place and the full 25% of gross rent was withheld all year, the landlord is not stuck with that as the final tax. Filing a section 216 return within two years of the end of the relevant tax year lets the CRA recalculate the tax on a net-income basis and refund the difference. This after-the-fact route works, but it means living with reduced cash flow for the year and waiting for a refund, which is why many landlords prefer to set up the NR6 in advance once they know the withholding pattern is going to repeat year after year.

What counts as rent for this purpose

The withholding rule is not limited to a monthly cheque from a long-term tenant. It applies to gross rental payments from any Canadian real property owned by a non-resident, including a single-family home, a condo unit, a commercial space, or a short-term rental booked through an online platform, provided the owner is a non-resident of Canada for tax purposes at the time the rent is paid. A parking space or storage unit rented out separately from a residential unit is treated the same way. What matters is the non-resident status of the owner and the Canadian location of the property, not the label attached to the payment or how the tenant found the listing.

A short-term rental adds a practical wrinkle, since the platform collecting payment on the owner's behalf is not automatically the withholding agent under Part XIII the way a property manager is; the obligation still generally falls back on the tenant or whoever is functioning as the owner's local agent, which makes it worth setting up a formal management arrangement rather than relying on the platform alone to sort out Canadian withholding.

Property managers as withholding agents

For owners who are not physically present to manage a Canadian rental property, a property manager frequently ends up handling the entire withholding and NR4 process as part of their service, since they are collecting the rent directly and are best positioned to remit correctly and on time. Property managers working with non-resident owners have their own set of cross-border considerations, which we cover in our guide for property management companies and cross-border tax.

How we handle this

For non-resident landlords, we set up the NR6 undertaking ahead of the tenancy wherever it makes sense, coordinate with the tenant or property manager on the mechanics of withholding and remitting, and prepare the section 216 return each year to make sure the final tax matches net income rather than the blunt 25% of gross rent. This sits alongside our cross-border tax services for clients who own Canadian property from outside the country.
