T4A-NR: The Ultimate Guide for Payments to Non-Residents in Canada

If your business pays non-residents for services performed in Canada, proper reporting isn’t optional—it’s legally required. Failure to withhold and report these payments using a T4A-NR slip can trigger penalties, interest, audits, treaty-based challenges, and difficulties for both the payer and the non-resident recipient.

The T4A-NR is a crucial compliance document used by Canadian businesses that hire non-resident contractors, consultants, performers, and service providers. It confirms that payments have been correctly reported and that Regulation 105 withholding has been properly remitted.

This guide covers everything you need to know to stay compliant in 2025.

 

What Is a T4A-NR Slip?

The T4A-NR – Statement of Fees, Commissions, or Other Amounts Paid to Non-Residents for Services Rendered in Canada is an information return required under the Income Tax Regulations.

It applies to payments made to:

• Non-resident individuals
• Non-resident corporations
• Non-resident partnerships

for services performed in Canada, other than employment income (which uses a T4).

 

Purpose of the T4A-NR Slip

1. Tax Compliance – Ensures the payer and non-resident meet CRA reporting requirements.
2. Withholding Verification – Confirms Regulation 105 withholding was applied and remitted.
3. Transparency – Provides the non-resident with documentation to file a Canadian tax return and claim credit for withheld tax.

 

Who Needs to File a T4A-NR?

You must issue a T4A-NR if you pay a non-resident for services performed in Canada, including:

1. Individuals

• Consultants
• IT professionals
• Coaches / instructors
• Technical specialists
• Independent contractors

2. Corporations

• Foreign consulting firms
• IT service companies
• Engineering or management service providers

3. Partnerships

• Non-resident professional firms
• Foreign technical teams operating in Canada

 

Examples of Payments Requiring a T4A-NR

• Consulting fees
• Management fees
• Technical service fees
• IT or software implementation services
• On-site project work
• Architectural, engineering, inspection, or testing services

 

When a T4A-NR Is NOT Required

A slip is not required where:

• All services are performed outside Canada
• The payment is employment income → issue a T4, not a T4A-NR
• The recipient is a Canadian resident for tax purposes
• The payment is subject to Part XIII rules instead (e.g., certain royalties)

Understanding these boundaries prevents over-reporting or missing required filings.

 

Regulation 105 Withholding: What You Must Know

Under Regulation 105 of the Income Tax Act, payers must withhold 15% of the gross amount paid to a non-resident for services rendered in Canada.

1. Mandatory 15% Withholding

• Applies to gross payments, not net.
• Applies even if the non-resident ultimately expects to owe less tax.
• Applies regardless of whether the payer is a corporation, partnership, or individual.

2. Treaties Do NOT Automatically Reduce Withholding

A tax treaty (e.g., Canada–U.S.) may reduce the final Canadian tax, but it does not automatically reduce the withholding rate.

To reduce withholding at source, the non-resident must first obtain a Regulation 105 waiver or reduction from the CRA.

3. Waivers and Reductions

Non-residents may apply for:

• R105 full waiver
• R105 partial reduction
• Simplified waiver (Form R105-S) for certain recurring engagements

The waiver must generally be approved before services are performed.

4. Remitting Withheld Amounts

Amounts withheld must be remitted to the CRA by the 15th day of the month following the payment.

 

Example: How Withholding Works

A Canadian business hires a U.K. IT consultant for $100,000 of on-site work in Vancouver.

• Required withholding = 15% × $100,000 = $15,000
• Consultant receives $85,000
• The $15,000 is applied as a credit when the consultant files a Canadian tax return

 

How to File a T4A-NR (2025 Step-by-Step Guide)

1. Collect Required Information

• Recipient name, address, and country of residence
• Recipient identifier (ITN, BN, or foreign tax ID)
• Gross payments for services
• Dates of service performed in Canada
• Amount withheld under Regulation 105
• Days present in Canada (required for certain industries)
• Travel reimbursements (if any)

 

2. Complete the T4A-NR Slip

Use CRA’s fillable PDF or certified software.

Key Boxes (Correct for 2025)

Box	Description
Box 18	Gross income for services rendered in Canada
Box 20	Travel expenses reimbursed (if applicable)
Box 22	Income tax deducted (Reg. 105 withholding)
Box 23	Reduction/waiver code
Box 24	City/province where services were performed
Box 26	Number of days in Canada
Box 27	Country of residence
Box 28	Industry code

These replace the incorrect “Box 14/16” descriptions sometimes found online.

 

3. File with the CRA

As of 2024 and continuing in 2025:

• If you file more than 5 T4A-NR slips, you must file electronically
• Paper filing is allowed only where you are filing 1–5 slips

Electronic filing can be done through:

• CRA Internet File Transfer (XML)
• My Business Account (PDF upload for up to 10 slips)

 

4. Provide Slips to Recipients

T4A-NR slips must be delivered to recipients no later than the last day of February following the year of payment.

 

5. Confirm Filing

Always verify in My Business Account that slips were accepted and processed.

 

Common Errors to Avoid

1. Failing to Withhold 15%

CRA can assess the payer directly for unremitted amounts plus penalties and interest.

2. Incorrect Recipient Information

Common errors include:

• Wrong country of residence
• Missing ITN/BN
• Incorrect gross income
• Misreporting travel reimbursements

3. Missing the Filing Deadline

Late-filing penalties apply:

• Range from $100 to $7,500, depending on number of slips

4. Misclassifying the Payment

Typical mistakes:

• Reporting employment income on a T4A-NR
• Reporting non-Canadian services on a T4A-NR
• Using a T4 instead of a T4A-NR for contractors

 

How to Amend a T4A-NR

If you discover an error after filing:

1. Identify the Issue

Is it:

• An incorrect amount?
• A withholding error?
• Wrong recipient details?
• Wrong country of residence?

2. File an Amended Slip

• Submit electronically (preferred) or
• Re-file a new T4A-NR slip marked “AMENDED”
• No revised summary is required

3. Notify the Recipient

Provide the corrected slip and recommend updating any tax filings.

 

Penalties for Non-Compliance

Late Filing

• $100 to $7,500, depending on number of slips

Failure to Withhold

CRA may assess:

• Full unremitted amounts
• Penalties
• Arrears interest

Failure to withhold is one of CRA’s highest-priority enforcement areas.
