1-800-548-4639If you filed a tax extension back in April, your filing deadline is October 15, 2026. That extension gave you more time to file your 2025 tax return, but it did not give you more time to pay any tax you may owe.
If you still have not filed, now is the time to get moving. Waiting until the final days can create unnecessary stress and make it harder to gather documents, review everything carefully, and file accurately.
Who the October 15 deadline applies to
The October 15 deadline generally applies to taxpayers who properly filed an extension by the original April filing deadline. If that applies to you, this is your extended deadline to submit your return.
If you did not file an extension in April, October 15 is not an extension deadline for you. In that case, your return may already be late, and filing as soon as possible is usually the best next step.
An extension to file is not an extension to pay
One of the most common misconceptions is that a filing extension also extends the time to pay. It does not.
If you owe taxes, interest and possible penalties may have been accruing since the original due date. Even so, filing your return by October 15 is still important because it helps you avoid additional filing-related issues and gets you back on track.
Do not wait until the last minute
Even if your return seems simple, waiting too long can create avoidable problems. Missing forms, questions about deductions, self-employment income, investment activity, or other issues can take longer to sort out than expected.
Filing now gives you more time to gather what you need and reduces the risk of rushing through something important.
Start gathering your documents now
If you have not already done so, this is a good time to collect the records needed to complete your return. Depending on your situation, that may include:
- W-2 forms
- 1099 forms
- Business income and expense records
- Mortgage interest or property tax statements
- Investment or retirement account documents
- Any tax documents you received earlier in the year
The sooner you gather your records, the easier it is to identify anything missing before the deadline gets too close.
Cornerstone handles return preparation for BC Tax clients
If you need help getting your return prepared, BC Tax clients work with our sister company, Cornerstone Financial Solutions, for in-house tax return preparation.
Cornerstone prepares current-year returns as well as past-due returns, and they can help clients who need to catch up or simply need to get their extended return filed correctly before the October 15 deadline.
Still need to file your 2025 tax return?
If you filed an extension in April, the October 15 deadline is approaching. Cornerstone can help you get your return prepared and filed accurately before the deadline.
What if you cannot pay in full?
If you expect to owe taxes but cannot pay the full amount right now, it is still important to file your return on time. Filing and paying are two separate issues, and not filing can often create bigger problems than filing and dealing with the balance afterward.
The key is to get the return filed first. Once that is done, you can review payment or resolution options based on your situation.
Bottom line
If you filed a tax extension in April, October 15, 2026 is your deadline to file your 2025 return. Do not wait until the last minute. Gather your documents, get your return prepared, and file as soon as possible so you can avoid unnecessary complications and move forward with confidence.
