NR301 form: payee signs, payer keeps, expires 3 years after year end

What goes in each of the eight parts of NR301?

The current NR301 is the 2013 edition, NR301 E (13), and the form itself fits on one page; the instructions sit on the pages after it, not on the canada.ca form page canada.ca. Your client's nonresident payee fills in Parts 1 to 8 canada.ca.

Part 8 is the substance of the form. The signer certifies the information is correct, that the taxpayer is the beneficial owner of all the income listed, that it is entitled to the benefits of the treaty with the Part 6 country on the Part 7 income, and undertakes to notify whoever received the form immediately of any change canada.ca.

The trust income trap is spelled out in the instructions: interest and dividends paid by a trust to a nonresident are trust income under the Act and Canada's treaties (a SIFT trust's deemed dividend under 104(16) is the exception) canada.ca. Some treaties also reduce the rate only when the income is taxable in the residence country; the form gives paragraph 2 of Article 27 of the Canada UK treaty as an example canada.ca.

Who signs NR301, who keeps it, and who carries the risk?

The nonresident completes it. The instructions name the signer by type: the individual taxpayer, an authorized officer of a corporation, the trustee, executor or administrator of a trust, or an authorized partner of a partnership canada.ca. Your client, the payer, doesn't fill it in for them.

It goes to whoever asked for it: the Canadian payer, or the agent, nominee or financial intermediary that requested it, or the partnership or hybrid entity the income flows through. The one time it goes to the CRA is when it supports a T2062 or T2062A certificate of compliance for treaty protected property canada.ca; that process is on the section 116 page.

Your client carries the risk, which is why it keeps the form. Part XIII tax is 25% of the gross amount laws-lois.justice.gc.ca, and a payer who fails to withhold what it should have is liable for the whole shortfall on the nonresident's behalf, with a right to recover it from the nonresident laws-lois.justice.gc.ca. The CRA can add a 10% penalty, or 20% for a second failure in the same calendar year made knowingly or through gross negligence canada.ca.

The form has no box for the treaty article or the rate. The payer looks up the reduced rate in the treaty for the Part 6 country canada.ca, using Finance Canada's list of treaties in force canada.ca. The instructions tell payers not to apply a reduced rate when there is no NR301 or equivalent information and they're unsure, the form is incomplete (blank tax number fields don't count), no treaty is in effect with the country, or they have reason to believe the declaration is incorrect or misleading canada.ca.

Worked example: what the form is worth on a $40,000 dividend

Your client, Canco, pays a $40,000 dividend on December 1, 2026 to each of two shareholders: USco, a US corporation owning 30% of Canco's voting shares, and Jane, a US resident individual holding a small block.

The 5% applies because USco is a company owning at least 10% of the voting stock; every other dividend to a US resident beneficial owner is capped at 15% (Article X(2)) canada.ca. Without the form and without a residential address, Canco can't satisfy itself that a reduced rate applies, so it withholds 25%.

Canco remits so the CRA receives the tax by December 15, 2026, the 15th of the month after payment, and reports both payees on 2026 NR4 slips canada.ca; dates are on the NR4 deadline page and slip codes on the NR4 codes page. If Jane's NR301 arrives after the payment, she claims the $4,000 excess on Form NR7-R, which the CRA must receive within two years from the end of the year the tax was sent, here by December 31, 2028 canada.ca.

Get it wrong the other way and the bill is Canco's. Applying 15% to Jane with no form and only a post office box leaves Canco liable for the $4,000 it didn't withhold, plus a 10% penalty on that amount, $400.

When does an NR301 expire?

For Part XIII purposes, the declaration expires at the earlier of a change in the taxpayer's eligibility for the treaty benefits, or three years from the end of the calendar year in which it was signed and dated canada.ca. The clock starts at December 31 of the signing year, not on the signing date.

A change ends it early. The CRA's own example is a mailing address that moves to a different country, which should prompt you to ask for a revised NR301 canada.ca. The payee has already undertaken in Part 8 to tell you of any change, and a change that makes the form wrong means a new form canada.ca. Diarize renewals: a stale NR301 is the same as no NR301.

NR301, NR302 or NR303: which form fits the payee?

NR301 is for a nonresident person. Partnerships use NR302 and hybrid entities use NR303 canada.ca.

NR302 and NR303 aren't standalone. The partnership or hybrid entity works out an effective rate of withholding on Worksheet A and certifies it holds an NR301, NR302 or NR303 (or equivalent information) for each partner or member whose treaty entitlement went into the rate canada.ca canada.ca. Both expire on a change in that effective rate or three years after the end of the year signed. A partnership taxed as a corporation in a treaty country can choose NR301 or NR302, whichever gives the better result.

Treat a US LLC with care. The CRA lists a partnership, a US LLC, any other flow through entity and a co ownership arrangement as cases where you should question whether the payee is the beneficial owner canada.ca. The US treaty also limits full benefits to qualifying persons under Article XXIX-A: US resident individuals qualify, while corporations and trusts must check the article canada.ca. Rates by payment type are on the Canada US treaty withholding page.

When should you not ask for an NR301 at all?

When the exemption comes from the Income Tax Act, not a treaty. The form isn't used for fully exempt interest under 212(3), arm's length interest outside 212(1)(b), or the reduced withholding on rent when the nonresident elects under section 216 canada.ca; see the section 216 page.

When the CRA has to issue something first. A US organization exempt under Article XXI of the US treaty needs a letter of exemption, and a pension exemption that depends on a threshold across all payers needs a CRA authorization requested on Form NR5 canada.ca. You reduce the withholding only after you receive the letter canada.ca.

When the payee is a US resident individual and you hold a full residential address. You can apply the treaty rate without NR301 if the address isn't a post office box or care of address, you know the payee is a US resident individual (or a US estate managed from the US), you have no reason to doubt the information, and your procedures trigger a rate review when details such as the country change canada.ca. Collect NR301 anyway when the benefit is conditional, for example on the amount being taxable in the residence country canada.ca.

When you'll withhold the full Part XIII rate anyway, or you pay an agent or nominee resident in Switzerland at the Canada Switzerland treaty rate canada.ca. Fees for services performed in Canada are a separate system: the payer withholds unless the nonresident provides a CRA waiver canada.ca; see the Regulation 105 page.
