Beginning in February 2026, the Canada Revenue Agency will introduce a new control mechanism within the EFILE and ReFILE systems that directly affects how electronic tax returns are transmitted.

Under this change, EFILE credentials will no longer function independently of tax software. Instead, each EFILE account will be locked to designated CRA-certified T1 and T3 software products, fundamentally changing how tax professionals manage electronic filings.

This development is particularly relevant for Canadian tax practices, accounting firms, and experienced tax lawyers in Canada who routinely file high volumes of individual and trust returns. Failure to align EFILE accounts with the correct software will result in rejected filings, administrative delays, and potential compliance challenges during peak filing periods.

Cryptocurrency Held Through A Bare Trustee: Tax Treatment And The 2026 Reporting Obligations

If you hold cryptocurrency, NFTs or other blockchain assets in someone else’s wallet, or hold assets in your own wallet for someone else, the arrangement is very likely a bare trust. Until recently, that carried almost no compliance consequence. It now carries three reporting obligations to track: the T3 filing for 2026, the T1135, and the proposed Crypto-Asset Reporting Framework from 2027.

How To Appeal The Toronto Vacant Home (VHT) Tax: Here’s What One Landlord Did To Fight VHT Assessment

Since 2022, the City of Toronto has imposed an annual Vacant Home Tax (VHT) on residential units left unoccupied for more than six months of the year. For most owners the tax is an afterthought: file the annual declaration, confirm the unit was lived in, and move on. But when the City’s administrative process breaks down, an owner can find themselves fighting a five-figure tax bill over a unit they insist was never vacant at all.
