## Recent changes you need to know
**CRA Drop-boxes**: all 45 CRA drop-box locations across Canada are being permanently closed **after May 29, 2026**, following the 2026 tax filing season. ([canada.ca](https://www.canada.ca/en/revenue-agency/news/newsroom/tax-tips/tax-tips-2026/drop-boxes-permanently-close-after-2026-tax-filing-season.html?utm_source=openai)) This affects individuals who currently submit returns, payments, or paper documents via drop boxes.
**CRA mail transition**: As of **May 28, 2026**, the CRA is expanding its initiative to move approximately **249,000 individuals** from paper mail to **online mail** within “My Account”. ([canada.ca](https://www.canada.ca/en/revenue-agency/campaigns/changes-from-paper-to-online-mail-for-some-benefit-recipients.html?utm_source=openai)) This is part of a larger transition that has shifted around 1.3 million individuals since mid-2025.
## Compliance risks and penalties
Failing to adapt to these changes could lead to:
- Missing deadlines if you don’t get mail in time (notice-of-assessment, reassessment, requests for information).
- late submissions if postal delays or misunderstanding of process occur.
- misplacing documents when paper options disappear.
CRA’s online system doesn’t reduce your responsibility: you must still respond to correspondence in full, even if via mail. Deadlines still matter.
## How to adapt and stay on top
- If you’re part of the paper-mail group and haven’t been notified, **verify your mailing preference in CRA My Account** and ensure your email is accurate. ([canada.ca](https://www.canada.ca/en/revenue-agency/campaigns/changes-from-paper-to-online-mail-for-some-benefit-recipients.html?utm_source=openai))
- Start using **online submission tools**—for returns, forms, payments—well ahead of deadlines. Regular mail still works, but drop-box option will be gone after May 29, 2026. ([canada.ca](https://www.canada.ca/en/revenue-agency/news/newsroom/tax-tips/tax-tips-2026/drop-boxes-permanently-close-after-2026-tax-filing-season.html?utm_source=openai))
- Keep physical copies of all documents you send until the CRA acknowledges delivery, whether digitally or by mail.
## Examples of impacted filers
- Taxpayers who used drop-boxes to submit paper returns may now need to migrate to **mail in a post officer sent envelope** or switch to **electronic filing or payment**.
- Benefit recipients or credit-claimers who get notices or assessments via mail need to be aware that they may no longer get paper notices automatically.
## Actionable checklist
- Update your CRA profile/profile-contact: correct email, ensure My Account access.
- Set up **direct deposit** if not done, to ensure payments reach you without delays.
- File electronically where possible: use NETFILE, CRA’s My Account, or certified software.
- Retain records: save PDFs/screenshots of submissions.
## Long-term trend: digital first
These changes align with Canada’s broader shift toward digital services: faster communication, improved security, cost savings, and environmental benefits. Staying proactive now simplifies future compliance, reduces risk of missed communication or penalties, and helps you take advantage of the CRA’s evolving digital tools.
