Canada Surtax Refund Timeline Through CARM

For importers waiting on a Canada surtax refund, the 90-day processing standard is an important benchmark, but it is not a guaranteed payment date. Claim accuracy, supporting records, CARM workflow issues, and the applicable remission order can all affect how quickly CBSA reviews and pays an eligible refund.

How Canada Surtax Refund Claims Work in CARM

Canada Border Services Agency generally processes commercial surtax remission claims by correcting or adjusting the Commercial Accounting Declaration, commonly called the CAD. The appropriate filing method depends largely on whether the payment due date for the affected accounting declaration has passed.

Corrections Before the Payment Due Date

When the CAD remains within the correction period before payment is due, an eligible importer or its authorized customs broker can generally submit a correction using reason code R5-00-COT. This approach revises the accounting declaration before the amount becomes final for payment purposes.

Corrections must identify the appropriate remission treatment and include the applicable special authorization code. The code must correspond to the goods and remission order involved. Using a code that does not match the imported product, origin, shipment date, or other eligibility conditions can lead to additional review or rejection.

Adjustments After the Payment Due Date

After the payment due date, the importer generally needs to submit a CAD adjustment through the CARM Client Portal or an available EDI or API channel. For eligible surtax remission claims, reason code R2-74-1-GR-53 may apply. The filer must also provide the correct special authorization code and claim amount.

For qualifying 2025 imports covered by the Steel Derivative Goods Surtax Remission Order, CBSA expanded the available authorization codes in November 2026 by adding 11 codes. Importers should confirm that the code selected reflects the exact goods and eligibility period rather than treating the remission order as blanket relief.

Claims generally must be submitted within two years of importation. That limitation makes early entry review important, particularly when an importer has hundreds or thousands of potentially eligible lines across multiple broker accounts.

How Long CARM Refund Processing Typically Takes

CBSA's established service standard for processing commercial CAD adjustments is 90 days. A properly submitted Canada surtax refund request should therefore be monitored against a 90-day benchmark, while recognizing that the standard is a processing target rather than a guarantee that funds will arrive within exactly three months.

Why Some Claims Take Longer Than 90 Days

Actual CARM refund processing times can extend beyond the service standard. More complex claims may require CBSA to validate tariff classification, country of origin, import dates, authorization codes, remission eligibility, supporting invoices, transportation records, or the relationship between individual CAD lines and the claimed amount.

Incomplete or inconsistent submissions are especially likely to take longer. A discrepancy between the refund schedule and the original CAD can trigger questions. The same is true when invoice descriptions do not clearly support the product covered by the remission order or when the importer cannot connect bills of lading to the affected entries.

CARM assistance backlogs can also affect visibility into a claim. As of mid-2026, thousands of assistance requests remained unresolved, with average resolution times measured in weeks and some individual cases remaining open substantially longer. These support delays do not necessarily mean the underlying adjustment has been denied. They can, however, make it harder to confirm whether a claim is assigned, under review, or awaiting additional information.

Importers have also experienced waits approaching six months for some surtax-related claims. That timeframe should not be treated as the standard for every filing, but it is a reasonable escalation point when no substantive status update has been received. Approval and payment may also occur at different times, so the date of the decision and the date funds become available should be tracked separately.

Managing a Delayed Canada Surtax Refund

A delayed claim requires structured follow-up rather than repeated general inquiries. The importer and customs broker should first confirm that the CAD correction or adjustment was successfully transmitted, accepted into CARM, and associated with the correct business number, importer account, transaction, reason code, and authorization code.

Build a Complete Claim Record

The claim file should include the original CAD, adjustment confirmation, invoices, purchase orders where relevant, bills of lading, product descriptions, origin records, calculation worksheets, and the remission eligibility analysis. Importers should also preserve screenshots, CARM transaction identifiers, correspondence, and dates of every follow-up request.

The refund calculation should reconcile at both the entry and line level. A summary spreadsheet may support the review, but it generally does not replace source documentation. CBSA may need to verify that the amount requested corresponds precisely to surtax previously paid on eligible goods.

Use Milestone-Based Follow-Up

During the initial 90-day period, the broker should monitor CARM for requests, notices, or status changes. If no decision appears after 90 days, the importer can ask the broker to confirm whether the adjustment remains active and whether CBSA requires additional evidence.

If the claim approaches six months without resolution, the parties should consider a more formal escalation through the appropriate CARM or CBSA support channel. The inquiry should identify the submission date, CAD number, adjustment reference, refund amount, relevant remission program, and prior case numbers. Concise, transaction-specific inquiries are generally easier to route than broad requests for an account review.

Importers should not file duplicate adjustments merely because the original claim appears delayed. Duplicate filings can create conflicting records and additional processing work. Any replacement or amended submission should be coordinated with the customs broker and supported by a clear explanation of why the original transaction must be changed.

Frequently Asked Questions

How Long Should a Canada Surtax Refund Take?

CBSA generally uses a 90-day service standard for commercial CAD adjustments. Straightforward, complete claims may be resolved within that period, while complex claims or filings affected by CARM support delays can take longer. Some claims have remained pending for approximately six months or more.

Does the 90-Day Standard Guarantee Payment?

No. The 90-day period is generally a service benchmark, not a guaranteed refund date. CBSA may request documentation, review remission eligibility, or verify calculations. Payment processing can also occur after the adjustment decision, creating a gap between approval and receipt of funds.

Can a Customs Broker Submit the Claim?

Yes. An authorized customs broker can generally submit the CAD correction or adjustment through the CARM Client Portal, EDI, or API under the applicable authority and account configuration. The importer remains responsible for the accuracy of the claim and its supporting records.

What Documents Support a Surtax Remission Claim?

A complete file typically includes invoices, bills of lading, the original CAD, proof of surtax paid, product and origin information, adjustment calculations, and evidence that the goods meet the remission order's conditions. Additional records may be required depending on the product and transaction.

Is There a Deadline for Filing a 2025 Refund Claim?

Eligible commercial surtax remission claims generally must be filed within two years of importation. Importers should calculate the deadline separately for each transaction rather than relying on a single date for all 2025 entries. Earlier filing also leaves time to correct errors or answer CBSA questions.

Should an Importer Resubmit a Claim That Is Delayed?

Not automatically. The importer should first confirm receipt and status with its broker and CBSA. Submitting a duplicate adjustment can complicate the account and delay review. A revised filing is more appropriate when the original claim contains an identified error and the amendment is properly documented.

How Stable Software Can Help

Extend Recovery Beyond Canadian Surtax Claims

Canadian surtax remission and U.S. duty drawback are separate recovery programs, but both reward disciplined transaction data, documentation, and claim governance. Customs brokers supporting importers with cross-border duty recovery can use DrawbackAI for U.S. duty drawback operations.

Stable Software provides DrawbackAI as flat-license duty drawback software that U.S. customs brokers can white-label for importer clients. Brokers file claims under their own filer code, maintain the client relationship, and pay a flat software license. Stable Software never takes a percentage of the refund. Brokers evaluating a scalable U.S. drawback offering can explore the platform as a complement to broader customs refund and trade compliance services.
