Part XIII Withholding: What Gets Withheld When You Leave Canada?
Part XIII of the Income Tax Act (sections 212-218) imposes a withholding tax on certain types of Canadian-source income paid to non-residents. The default rate is 25% of the gross payment. The Canada-US tax treaty reduces the rate on most categories: 15% on periodic pension payments, 15% on dividends (5% for significant shareholders), 0% on most interest, and 0% or reduced rates on various other income types.
When you leave Canada and become a non-resident, every Canadian payer (your bank, your RRSP custodian, your pension plan, your former employer, the tenant of your rental property) must start withholding Part XIII tax on payments to you. The withholding is the final Canadian tax on that income; you generally do not file a Canadian return to report it (unless you elect to under Section 216 or 217, which can produce a lower effective rate).
Part XIII withholding is automatic: the payer deducts it before sending you the money. The default rate is 25%. For US residents, the treaty reduces the rate on most income types. The NR4 slip (the non-resident’s T-slip equivalent) reports the gross amount and the tax withheld. The withheld amount is your final Canadian tax liability on that income, unless you file an optional Canadian return (Section 216 for rental income, Section 217 for pension/RRIF income) to be taxed at graduated rates instead.
What’s Part XIII withholding tax?
It is the tax Canada charges on certain types of income paid to non-residents, collected at source by the payer before the money leaves the country. The authority is Part XIII of the Income Tax Act (sections 212 through 218), and the default rate is 25% of the gross payment with no deduction for expenses. The payer (your bank, pension plan, RRSP custodian, or tenant) deducts the tax and remits it to the CRA; you receive the net amount. The withheld tax is generally your final Canadian tax on that income unless you elect into Section 216 or 217.
- Income types covered: pensions, RRSP and RRIF withdrawals, dividends, certain interest, rents, royalties, management fees, and several other categories of Canadian-source income.
- Section 216 (rental income) and Section 217 (pension/RRIF) let you file a Canadian return and pay graduated rates, which may produce a lower effective rate than the flat 25% or treaty-reduced withholding.
What are the treaty-reduced rates for US residents?
For a Canadian non-resident who is a US resident, the Canada-US tax treaty reduces Part XIII withholding as follows:
| Income type | Default Part XIII rate | Treaty-reduced rate (US residents) | Treaty article |
|---|---|---|---|
| Periodic pension/annuity payments | 25% | 15% | XVIII(2) |
| Lump-sum pension payments | 25% | 25% (no reduction for lump sums, but see Section 217) | XVIII(2) note |
| RRSP annuity payments (after maturity) | 25% | 15% | XVIII(2)(a) |
| RRSP withdrawals before maturity (lump-sum or partial) | 25% | 25% (not periodic, but see Section 217) | - |
| RRIF withdrawals (minimum and periodic amounts, up to the greater of 2x the minimum or 10% of the January 1 value) | 25% | 15% (periodic) | XVIII(2)(a) |
| RRIF withdrawals (above that periodic limit) | 25% | 25% (not periodic) | - |
| Dividends (general) | 25% | 15% | X(2)(b) |
| Dividends (substantial shareholder, 10%+) | 25% | 5% | X(2)(a) |
| Interest (arm’s-length) | 25% | 0% | XI(1) |
| Interest (related-party, non-arm’s-length) | 25% | 0% (post-2008 treaty protocol) | XI(1) |
| Rental income (gross) | 25% | 25% (no treaty reduction, but Section 216 election available) | VI |
| Royalties | 25% | 0% (copyright, software, patents, know-how), 10% (others, such as trademarks) | XII |
| Management fees | 25% | 0% (if Article VII business profits apply) | VII |
| CPP/OAS | 25% | 0% (taxable only in US) | XVIII(5) |
| Estate/trust income | 25% | 15% (generally, depends on income type) | Various |
How to establish your treaty rate
The payer needs to know you are a US resident to apply the treaty rate instead of the 25% default. Two mechanisms:
NR301 (Declaration of Eligibility for Benefits Under a Tax Treaty for a Non-Resident Taxpayer). File this form with each Canadian payer (your bank, brokerage, pension administrator, RRSP custodian). It declares your country of residence and the treaty article you are relying on. The payer then withholds at the treaty rate.
NR5 (Application by a Non-Resident of Canada When Completed for a Reduction in the Amount of Non-Resident Tax Required to Be Withheld). For pension and RRIF income, you can apply to CRA directly for a reduced withholding rate. CRA issues a letter to the payer authorizing the reduced rate. This is more formal than the NR301 and involves CRA review.
If you do not file the NR301 or NR5, the payer withholds at 25%. You can recover the excess withholding by filing a Canadian non-resident return, but it is easier to establish the treaty rate upfront.
Section 216: rental income
The 25% gross withholding on rental income is often higher than the tax that would be owed if the rental income were taxed on a net basis (after expenses). Section 216 of the ITA allows a non-resident to elect to file a Canadian return reporting the net rental income (gross rent minus expenses: mortgage interest, property taxes, maintenance, property management, depreciation). The tax on the net income at graduated rates is usually much less than 25% of gross rent.
To use Section 216, you must file the return within two years of the end of the taxation year. You can also file an NR6 form before the year starts, which allows the payer (your property manager or tenant) to withhold based on estimated net income rather than 25% of gross, reducing the cash flow impact.
Example: gross rent of $30,000, expenses of $18,000, net rental income of $12,000. Part XIII at 25% of gross = $7,500. Section 216 tax on $12,000 net at graduated rates = approximately $1,800 (federal only, no provincial tax for non-residents). The Section 216 election saves $5,700.
Section 217: pension and RRIF income
Section 217 allows non-residents to elect to file a Canadian return and be taxed at graduated rates (as if they were residents) on certain Canadian-source income, primarily pension income, RRSP/RRIF withdrawals, CPP, OAS, and certain death benefits. The election is beneficial when the graduated rate on the income is lower than the flat Part XIII rate.
The catch: Section 217 requires you to report your worldwide income on the Canadian return (to determine the appropriate graduated rate), even though only the Canadian-source income is actually taxed. If your worldwide income is high, the graduated rate on the Canadian pension income may be higher than the Part XIII rate, and the election is not beneficial.
When Section 217 helps: when your total worldwide income is low enough that the graduated rate on the Canadian pension/RRIF income is below the 15% treaty rate (or 25% default rate). This is common for retirees whose primary income is the Canadian pension itself, with relatively little other income.
When Section 217 does not help: when your worldwide income pushes the graduated rate above the withholding rate. A retiree with $100,000+ of US-source income plus $30,000 of Canadian RRIF income may find that the graduated rate on the RRIF income (when stacked on top of worldwide income) exceeds 15%.
Is the RRIF minimum exempt from withholding?
No. ITA 212(1)(q) applies the 25% Part XIII tax to RRIF payments to non-residents, minimums included. For a US resident, the treaty cuts it to 15% on periodic payments. For a RRIF, payments count as periodic up to the greater of twice the year’s minimum or 10% of the fund’s value at the start of the year, so a minimum-only withdrawal is withheld at 15%, not zero.
The US taxes the full withdrawal as ordinary income, and you claim a foreign tax credit for the Canadian tax withheld, so the 15% usually offsets US tax on the same income rather than adding to it.
- Above the periodic limit: once the year’s withdrawals pass the greater of twice the minimum or 10% of the January 1 value, the payment that crosses the line and every payment after it that year are withheld at 25%.
- Cash flow planning: keeping each year’s withdrawals within the periodic limit holds the Canadian withholding at 15%. The RRIF conversion guide works through the limit, and the lump-sum vs periodic withdrawal analysis covers the US-side math on the same decision.
What you need to do when you leave
When you become a non-resident:
- Notify all Canadian payers of your change in residency. Provide each payer with an NR301 (or NR5 for pensions/RRIFs) to establish the treaty-reduced withholding rate.
- Notify CRA of your departure (you can do this on your final Canadian resident return, or by calling CRA to update your status).
- Update your address with Canadian financial institutions to your US address. This triggers the payer’s non-resident withholding obligation.
- File your final Canadian resident return (the return for the year you became a non-resident, reporting worldwide income to the date of departure and Canadian-source income for the remainder of the year).
- Set up Section 216 (rental income) if you have Canadian rental property. File the NR6 before the year starts to reduce withholding to estimated net income.
What should I do next?
If you are leaving Canada, identify every Canadian payer (bank, RRSP/RRIF custodian, pension plan, rental tenant, investment account). File NR301 or NR5 with each one. If you have rental property, file NR6 for the current year to reduce gross withholding. File Section 216 and consider Section 217 at tax time.
