OECD ADAPTS TO REMOTE WORK ECONOMY

HOME OFFICES AS POTENTIAL PERMANENT ESTABLISHMENTS IN REMOTE WORK ERA

On November 19, 2025, the Organization for Economic Co-operation and Development (“OECD”) released an update to the OECD Model Tax Convention on Income and on Capital (the “2025 Update”).

Among the changes are important clarifications to the Commentary on Article 5, dealing with the meaning of Permanent Establishment (“PE”) – and more specifically directed at helping determine when an individual’s home office may constitute a PE of the enterprise engaging the worker.

In a world increasingly shaped by remote work, changes like these are timely and likely only the beginning of further developments – and tax audits!

BC EXTENDS PST TO NEW SERVICES

PROVINCE ANNOUNCES EXPANSION OF SALES TAX TO PROFESSIONAL SERVICES

British Columbia has recently announced a further expansion of its Provincial Sales Tax (“PST”) base – a move that will not surprise those who have watched the province’s post-HST trajectory.

BC briefly participated in Canada’s Harmonized Sales Tax (“HST”) system in 2010, only to exit following a 2011 referendum and revert to its standalone PST system in April 2013. Since returning to a traditional retail sales tax model, the defining feature of PST policy has been base expansion – likely to help address recent provincial fiscal commitments and infrastructure projects.

We review the latest plan below.

DEVELOPING BIAS DOCTRINE IN CANADA

ONTARIO COURT OF APPEAL: IF BIAS SHOWN, DECISION MUST BE OVERTURNED!

As we have written here before, proving bias tends to be an uphill battle. Because of that, this ground of complaint is rarely pursued in tax or trade appeals. That may be changing, given a recent ruling of the Ontario Court of Appeal (“ONCA”) in a trade remedy case, which confirmed that if a complainant can prove a “reasonable apprehension of bias” in the decision-making process, the entire decision must be overturned!

In this Tax Appeals Series blog, we review that decision and examine the potentially HUGE consequences that can follow.
