## Why Digital Security in Tax Matters Now The CRA is introducing **mandatory backup multi-factor authentication (MFA)** for CRA accounts beginning **February 2026**. If your primary MFA method is lost (e.g. lost phone or lost passcode), having a backup ensures you can still access your account and avoid delays or refunds getting held up.

Be cautious: phone-based MFA isn’t accepted as backup.

Be aware that from July 2025, EFILE’s authorize-representative function via software is no longer available.

She earns Canadian-source income (e.g. rental, investments). She logs in to her CRA account to file taxes under Guide T4058. - Emma needs her CRA account active and secure. A lost smartphone without backup MFA might block her access when filing using NETFILE. - For forms like foreign income or treaty tax deductions for non-residents, obtaining accurate slips, etc., through MyAccount is easier when fully set up. - Since slips are moving towards **digital delivery only**, she should confirm her email, address, and preferences are up to date.

If you miss account access or FEM setup, you’ll face delays.

Paper copies may be phased out.

Proactive setup is better than reactive. ## Actionable Checklist | ✅ Task | You’ll gain... | |---|---| | Add backup MFA option now | Ensure access even if primary method fails | | Update contact info (email, phone, mailing address) | Prevent missed notices or delayed refunds | | Review representative authorizations | Smooth coordination if someone files on your behalf | | Check device readiness for digital slips | Know where your documents will arrive | | Clear your calendar around Feb-23-April-30, 2026 | Reduce stress by preparing early | --- These digital compliance measures are relatively small steps—but they pay dividends in preventing headaches during the busiest time of the tax year.
