NR301: The Form That Cuts Canadian Withholding From 25% to the Treaty Rate, and the NR7-R That Recovers It When You Forgot

Canada withholds Part XIII tax at 25% on most passive income paid to non-residents: dividends, periodic pensions, RRSP and RRIF withdrawals, rent, royalties, and certain interest. The Canada-US treaty reduces the rate on most of these (15% on dividends and periodic pensions, 0% on most interest and royalties), but the Canadian payer applies the reduced rate only if the recipient has certified their treaty eligibility on Form NR301. Without it, the payer withholds 25%, and the recipient's only recourse is a refund application on Form NR7-R within two years. The NR301 is the single form that saves US residents the most Canadian tax, and it expires.

Key takeaways

• NR301 is a declaration by a non-resident individual or corporation that they are resident in a treaty country and eligible for the treaty's reduced Part XIII rate. It is given to the Canadian payer (bank, broker, pension administrator, RRSP issuer, tenant's agent), not filed with the CRA, and is valid for three years from signature or until the information changes.
• NR302 is the equivalent for partnerships; NR303 for hybrid entities (such as US LLCs) that need to look through to their members' treaty eligibility.
• Treaty rates for US residents: 15% on dividends (5% for a corporate shareholder owning 10% or more); 15% on periodic pension, RRIF, and annuity payments within the periodic limit; 25% on lump-sum RRSP withdrawals (no treaty reduction); 0% on arm's-length interest (exempt domestically) and most non-arm's-length interest; 0% on most royalties; 25% on rent (reducible to net-basis withholding only through NR6, not NR301).
• Refunds: Part XIII withheld above the treaty rate is recovered on Form NR7-R, filed by the recipient with the payer's NR4 slip, within two years after the end of the year in which the tax was remitted. After two years, the excess is lost.
• The payer's exposure: a payer that applies a reduced rate without an NR301 on file is liable for the shortfall; payers therefore withhold 25% by default.

What the form does

Form NR301 identifies the recipient, their country of residence, their foreign taxpayer identification number (US SSN or ITIN), the type of income, and the treaty article and rate claimed, and certifies that the recipient is the beneficial owner and meets the treaty's limitation-on-benefits requirements. The payer keeps it and applies the reduced rate to future payments. It must be renewed every three years, and a new one is needed if the recipient moves to a different country or the income type changes.

For a US resident, the NR301 is given to: the Canadian brokerage holding Canadian dividend-paying stocks; the RRSP or RRIF issuer before the first periodic withdrawal; the pension plan administrator before the first pension payment; and any Canadian corporation paying dividends or interest to a related US-resident shareholder. It is not needed for arm's-length bank interest (exempt without the treaty) or for CPP and OAS (exempt for US residents under Article XVIII(5), applied by Service Canada on notification of US residence).

The rates by income type

• Dividends (Article X): 15% for individuals and for corporations owning less than 10%; 5% for a corporation owning 10% or more of the voting stock.
• Periodic pension and annuity payments (Article XVIII(2)): 15%, including RRIF payments within the periodic limit (the greater of twice the required minimum and 10% of the year-opening value).
• RRSP lump-sum withdrawals and RRIF withdrawals above the periodic limit: 25%; no treaty reduction.
• Interest (Article XI): 0% on most interest; arm's-length interest is exempt under domestic law anyway; non-arm's-length interest needs the NR301 for the treaty zero rate; participating interest 15%.
• Royalties (Article XII): 0% on copyright, software, and certain other royalties; 10% on others.
• Rent: 25% on gross rent under domestic law; the NR301 does not reduce it; Form NR6 with a Canadian agent switches withholding to 25% of net rent, and the Section 216 return computes the actual tax.
• CPP and OAS: 0% for US residents; no NR301 needed; notify Service Canada of US residence.
• EI: 25%; no treaty reduction.

NR302 and NR303

A partnership receiving Canadian-source income files NR302, listing its partners and their treaty eligibility, so the payer can apply a blended rate. A hybrid entity (an entity treated as fiscally transparent in one country and not the other, most commonly a US LLC receiving Canadian income) files NR303, which looks through to the members; Canada extends treaty benefits to a US LLC's income only to the extent its members are US residents entitled to benefits, under Article IV(6).

Recovery: NR7-R

If the payer withheld 25% because no NR301 was on file, the recipient files Form NR7-R with a copy of the NR4 slip and the NR301 (or evidence of treaty residence), requesting a refund of the excess. The application must be filed within two years after the end of the calendar year in which the tax was remitted; tax withheld in 2025 must be applied for by December 31, 2027. The CRA processes NR7-R applications slowly, and one application is required per payer per year.

The recipient cannot instead claim 25% as a foreign tax credit in the US: the US credit is limited to the treaty rate (Article XXIV), so the excess is recoverable only from Canada.

Worked example

A Toronto retiree who moved to Scottsdale in 2023 holds a $700,000 RRIF, $200,000 of Canadian bank shares at a Canadian broker, and receives a $30,000 defined benefit pension. She has never filed an NR301.

• RRIF. Periodic withdrawals of $35,000 a year (within the limit) withheld at 25% ($8,750) instead of 15% ($5,250): $3,500 a year over-withheld.
• Dividends. $8,000 a year withheld at 25% ($2,000) instead of 15% ($1,200): $800 over-withheld.
• Pension. $30,000 withheld at 25% ($7,500) instead of 15% ($4,500): $3,000 over-withheld.
• Total. $7,300 a year over-withheld since 2023. US foreign tax credit limited to the treaty rate; the excess not creditable.
• Fix. NR301 filed with the RRIF issuer, the broker, and the pension plan now (three-year validity). NR7-R applications for 2024 and 2025 (2023 is still within the window until December 31, 2025, if filed in time; otherwise lost). About $14,600 recoverable for 2024 and 2025.

Practitioner note

The NR301 is a one-page form worth thousands of dollars a year, and it is not on file for most US-resident clients who arrive at our door. We file it with every Canadian payer in the first meeting, calendar the three-year renewal, and file NR7-R for the years still open. The two-year window closes quietly, and the US credit will not cover the difference.
