The Canada Revenue Agency (CRA) says updating a mailing address to include "Haida Gwaii" does not determine whether a Northern Residents Deduction claim is selected for review, but it acknowledges that address information may be considered as part of the review process.

The clarification comes after Haida Gwaii News asked why several Haida Gwaii residents reported their reassessments were reduced or resolved after updating their CRA address to include "Haida Gwaii."

Residents first began raising concerns following Haida Gwaii's move from Intermediate Zone B to Prescribed Northern Zone A, which allows eligible residents to claim the full Northern Residents Deduction beginning with the 2025 tax year.

Literacy Haida Gwaii said it heard from numerous residents who received requests to provide proof of residency after claiming the expanded deduction. The organization suggested the reviews may have been linked to how Haida Gwaii appeared in the CRA's updated northern zone listings, noting that individual communities such as Daajing Giids, Masset, Port Clements, Sandspit and Skidegate no longer appeared separately under the Zone A designation.

One resident, Astrid Egger, told Haida Gwaii News that after updating her CRA address to include "Haida Gwaii," her reassessment was reduced and she was required to repay only half of the original amount.

In response to questions from Haida Gwaii News, the CRA said the Zone A listing itself does not determine whether a return is reviewed.

"The Canada Revenue Agency can confirm that the change from listing individual communities to listing only 'Haida Gwaii' does not affect whether a return is selected for review," the agency said.

However, after being asked about residents whose reassessments appeared to change after updating their address, the CRA provided further clarification.

"As part of its review activities, the Canada Revenue Agency (CRA) may request documents to support claims made by taxpayers," the agency said.

"In some cases, a review may be resolved using information already available to the CRA. As a result, additional documentation may not be required from the taxpayer."

The CRA added that updates to information already on file, including address information, may be considered during the review process.

"Updates to information on file, including address information, may be considered along with other information available to the CRA during the review process," the agency said. "Changing an address to include 'Haida Gwaii' does not, by itself, determine whether a return is selected for review or the outcome of that review."

The agency also said it has "not identified any issues with the prescribed northern zone designations" and that eligibility for the Northern Residents Deduction is determined by geographic areas prescribed in the Income Tax Regulations. Questions regarding those designations should be directed to the Department of Finance.

The CRA declined to say how many Haida Gwaii returns have been selected for review, saying it does not release claim-level statistics because doing so could compromise the integrity of its compliance programs.

It also said Northern Residents Deduction claims are not reviewed more frequently than other tax claims.

"The CRA is obliged to review a number of returns each year to ensure that individuals are entitled to the claims that they have made, and that amounts claimed have been correctly calculated," the agency said. "These claims are not subject to any higher frequency of review than are other claims."

The concerns prompted Literacy Haida Gwaii to raise the issue publicly and Member of Parliament Ellis Ross to write to National Revenue Minister François-Philippe Champagne requesting a review of the reassessment process and clearer guidance for affected taxpayers.

For residents who receive requests to verify their eligibility, the CRA said acceptable proof of residency may include rent receipts, property tax bills, utility bills, lease agreements and home insurance statements showing they lived in a prescribed northern zone for at least six consecutive months during the tax year.
