IRS Urges Extension Filers: File Soon, Don't Wait for October 15

Summary

In a reminder released on August 26, 2026 (IR-2026-101), the Internal Revenue Service encouraged taxpayers who requested an extension to file their 2025 federal tax return as soon as possible rather than waiting until the October 15 deadline. The IRS also noted that extension filers can use IRS Free File this summer to complete their returns. For Canadian residents with US filing obligations — whether those obligations stem from US citizenship, green card status or US-source income — filing as soon as the return is ready beats racing the deadline in October, and it can also bring a refund into hand sooner.

Our Take

An extension moves the filing deadline from the regular spring date to October 15; it does not mean the return can wait indefinitely. The IRS message is a practical one: once the information is in hand, filing early is usually better than filing at the last moment. That logic carries extra weight for cross-border filers. Canadian residents preparing a US return often need to coordinate foreign account reporting, foreign tax credits and the treatment of pensions and investment income across two countries' rules; leaving that work until mid-October leaves little room if documents are missing or a return needs correction. Free File is the IRS's free electronic filing channel, and eligible taxpayers can use it on their own — but cross-border situations are frequently more involved than the standard case, and eligibility varies by individual. Our general guidance: assemble the relevant Canadian and US documents early, and file once the return is ready rather than waiting for the deadline to arrive. If you have questions about your US filing obligations or how to handle an extension, consult a licensed CPA.
