NR6: How to Reduce Your Part XIII Withholding from Gross to Net

## NR6: How to Reduce Your Part XIII Withholding from Gross to Net When you become a non-resident of Canada but continue to own Canadian rental property, the Canada Revenue Agency requires that 25% of your gross rental income be withheld and remitted as Part XIII tax. This withholding occurs at the source—meaning your tenant or property manager must collect and remit this amount on your behalf. For many non-resident landlords, this creates a significant cash flow problem. If your property generates $3,000 per month in gross rent, a full $750 is withheld regardless of your actual expenses. After paying your mortgage, property taxes, insurance, and maintenance costs, you might have very little—or even negative—net income. Yet the withholding still applies to the full gross amount. The NR6 form offers a solution. By filing this undertaking with the CRA, you can arrange for withholding to be calculated on your estimated net rental income instead of gross rents, dramatically improving your cash flow throughout the year. ### Understanding the Default Part XIII Withholding Before exploring the NR6 option, it's important to understand what happens without it. Under Part XIII of the Income Tax Act, any person paying rent to a non-resident of Canada must withhold and remit 25% of the gross payment to the CRA. This applies whether the payer is: - A property management company - A Canadian resident tenant - Another non-resident tenant The withholding must be remitted to the CRA by the 15th day of the month following the payment. The payer must also file an NR4 slip by March 31 of the following year, reporting the total amounts paid and withheld during the calendar year. This 25% rate applies to gross rents without any deduction for expenses. The logic behind this approach is administrative simplicity—the payer has no way of knowing your actual expenses, so the CRA requires withholding on the full amount as a collection mechanism. ### What the NR6 Form Accomplishes Form NR6, titled "Undertaking to File an Income Tax Return by a Non-Resident Receiving Rent from Real or Immovable Property or Receiving a Timber Royalty," allows you to change how withholding is calculated. When approved by the CRA, your agent (typically your property manager) can withhold 25% on your estimated net rental income rather than gross rents. The key word here is "undertaking." By filing an NR6, you are making a legal commitment to file a Section 216 income tax return for the year, reporting your actual rental income and expenses. This is not optional once the NR6 is approved—failing to file the required return triggers penalties and can result in reassessment at the gross withholding amount. ### Calculating Your Potential Savings Consider a practical example. You own a rental property generating $36,000 annually in gross rent. Your annual expenses include: - Mortgage interest: $12,000 - Property taxes: $4,000 - Insurance: $1,500 - Property management fees: $3,600 - Maintenance and repairs: $2,400 - Utilities (landlord-paid): $1,200 Your total expenses amount to $24,700, leaving net rental income of $11,300. Without an NR6, the annual withholding would be 25% of $36,000 = $9,000. With an approved NR6, the annual withholding would be 25% of $11,300 = $2,825. The difference of $6,175 remains in your pocket throughout the year rather than being held by the CRA until you file your return and claim a refund. ### Who Must Sign the NR6 The NR6 requires signatures from two parties: **Part 2 – The Non-Resident:** You must provide your identifying information, property details, and estimated income and expenses for the upcoming year. Your signature confirms your undertaking to file a Section 216 return. **Part 3 – The Agent:** Your Canadian agent—whether a property manager, relative, or other representative—must also sign the form. Their signature confirms they will withhold and remit tax based on the net amount shown in the approved NR6 and that they accept responsibility for any shortfall if actual net income exceeds the estimate. This dual-signature requirement means you cannot file an NR6 if you're collecting rent directly from tenants without a Canadian agent. You need someone in Canada to act as your agent and accept the withholding obligations. ### Filing Deadlines and Timing The NR6 must be filed on or before the later of: - January 1 of the year to which it applies, or - The date that is 30 days before the first rental payment of the year For most established rental properties, this means filing by January 1. However, if you purchase a property mid-year or become a non-resident partway through the year, you have 30 days before the first applicable rental payment to submit the form. The CRA typically processes NR6 forms within a few weeks. You should receive written approval before your agent begins withholding on the net amount. Until approval is received, your agent should continue withholding at 25% of gross rents to avoid penalties. ### Step-by-Step Filing Process **Step 1: Gather Your Information** Collect details about your rental property, including the address, your Canadian agent's information, and your non-resident address. You'll also need your Social Insurance Number or Individual Tax Number. **Step 2: Estimate Your Income and Expenses** Prepare reasonable estimates of your rental income and deductible expenses for the upcoming year. Base these on historical figures where available, adjusting for known changes such as rent increases or planned repairs. Be conservative—underestimating expenses could result in under-withholding and potential penalties for your agent. **Step 3: Complete the Form** Form NR6 is available on the CRA website. Complete all required sections, ensuring both you and your agent sign the form. Electronic signatures are not accepted; original signatures are required. **Step 4: Submit to the CRA** Mail the completed form to: International and Ottawa Tax Services Office Post Office Box 9769, Station T Ottawa ON K1G 3Y4 Alternatively, you can fax the form to 1-613-941-2505. **Step 5: Await Approval** Do not begin withholding on net amounts until you receive written CRA approval. Keep a copy of the approval letter with your tax records. ### Your Obligation to File a Section 216 Return Once your NR6 is approved, you are legally committed to filing a Section 216 return for that tax year. This return must be filed by June 30 of the year following the calendar year in question. For example, if your NR6 covers the 2024 tax year, your Section 216 return is due by June 30, 2025. On the Section 216 return, you report your actual rental income and claim your actual expenses. The tax calculated on this return is then compared against the amounts withheld throughout the year. If you owe additional tax, you must pay it with the return. If you overpaid through withholding, you'll receive a refund. Failure to file the Section 216 return by the deadline has serious consequences. The CRA can reassess your tax liability based on 25% of gross rents, eliminating any benefit from the NR6 and potentially creating a substantial tax bill plus interest. ### Renewing Your NR6 Annually The NR6 is valid for one calendar year only. You must file a new NR6 each year to continue benefiting from net withholding. Mark your calendar for December to prepare and submit the renewal before the January 1 deadline. Each year's NR6 should reflect updated estimates based on current rental rates and anticipated expenses. Significant changes in your situation—such as refinancing, major renovations, or rent adjustments—should be reflected in your new estimates. ### Common Mistakes to Avoid **Overestimating expenses:** If your actual net income exceeds your NR6 estimate, your agent may be liable for the shortfall in withholding. Be realistic in your projections. **Missing the filing deadline:** Late NR6 submissions may not be processed in time, forcing gross withholding until approval is received. **Forgetting the Section 216 return:** The NR6 benefit comes with strings attached. Missing the June 30 deadline can result in assessment at gross rates plus penalties. **Not obtaining agent agreement:** Your agent must be willing to accept the responsibilities that come with the NR6. Discuss this before filing. ## Frequently Asked Questions ### Can I file an NR6 if I manage the property myself without a Canadian agent?
