Tax Day Reminder: Does an IRS Payment Count as Filing an Extension?

As we reach the tax filing deadline today, one of the most common questions I hear is:
“If I make a payment on IRS.gov, does that count as filing an extension?”
The answer is simple—but very important.
The Short Answer
A payment made through the Internal Revenue Service website does not automatically count as filing an extension.
However, it can—if it is submitted correctly.
When a Payment Does Count as an Extension
If you make a payment online and properly designate it as an extension payment—typically by selecting:
- “Extension”
- or “Form 4868”
…then the IRS treats that payment as a validly filed extension.
👉 In this case, you do not need to file a separate Form 4868.
When a Payment Does Not Count
If you submit a payment and choose:
- “Balance Due”
- “Estimated Tax”
- or any category other than “Extension”
…then no extension has been filed, even though the IRS received your money.
This is where many taxpayers unintentionally make a costly mistake.
The Safe Approach
If there is any doubt at all about how the payment was coded:
👉 File Form 4868 anyway.
There is no downside to filing the extension form, and it ensures you are protected.
Important: An Extension Is Not an Extension to Pay
This is critical and often misunderstood:
- An extension gives you more time to file your return (typically until October 15)
- It does not give you more time to pay your taxes
If you owe money and do not pay by today:
- Interest will accrue
- Penalties may apply
What You Should Do Today
If you are not ready to file:
- Submit an extension (Form 4868)
– electronically or through your tax preparer - Pay as much as you reasonably can
– even partial payments reduce penalties and interest - Confirm your payment designation
– make sure it is coded as an extension if that is your intent
A Practical Rule to Remember
A payment only counts as an extension if the IRS knows it’s for an extension.
