Yes, it is possible to file tax returns after the deadline, but you should do so immediately to minimize penalties and interest. While you can file late, you cannot extend the time to pay taxes owed, and failing to file on time may lead to penalties. If you are owed a refund, there is generally no penalty for filing late, but you should still file within three years to claim it.
Yes, you can still file your taxes after the deadline, and you should file as soon as possible to minimize penalties and interest, especially if you owe taxes, but remember an extension to file (until October) isn't an extension to pay; you should estimate and pay any owed taxes by the April deadline to avoid failure-to-pay penalties.

IRS Definition
A failure to file penalty is charged on returns filed after the due date or extended due date, absent a reasonable cause for filing late. The combined penalty is 5% (4.5% late filing and 0.5% late payment) for each month or part of a month that your return was late, up to 25%.
In addition to a fine, the ATO can also apply General Interest Charges (GIC), on any amount still owing. Note: The rate for GIC changes quarterly. At the time of writing this article, the rate is 10.61% per annum (October – December 2025).

If you need more time to file your taxes, request an extension by the April tax filing due date. This gives you until October 15 to file without penalties. Make sure you pay any tax you owe by the April filing date. The extension is only for filing your return.
