There’s No Such Thing as a Tax Extension

If you file a tax extension, do you get more time to pay your taxes?

Generally, no.

An IRS tax extension gives most individual taxpayers more time to file their tax return. It does not automatically give them more time to pay the tax they owe.

That distinction sounds small. Financially, it can be a very big deal.

As an Enrolled Agent, this is one of the most common tax misconceptions I run into. Every year, people tell me some version of:

“I filed an extension, so I have until October to deal with my taxes.”

Not exactly.

What you filed was an extension of time to file your return.

Your tax bill was still generally due on the original April filing deadline.

Does a Tax Extension Give You More Time to Pay?

For most individual taxpayers, filing Form 4868 gives you an automatic six-month extension to file your federal income tax return.

That additional time can be extremely useful.

Maybe you're waiting for a K-1. Maybe your bookkeeping isn't finished. Maybe you're missing documents. Or maybe your return involves complicated tax issues that shouldn't be rushed just to hit an April deadline.

An extension gives you additional time to prepare and file an accurate return.

But the extension generally does not move the deadline for paying your taxes.

If you ultimately owe money, the IRS generally expects that tax to have been paid by the original due date.

What Happens If You Owe Taxes After April 15?

Suppose you estimate that you owe $10,000.

You file an extension in April but don't send any payment because you assume the extension means everything can wait until October.

Then you complete the return in October and discover that, sure enough, you owe $10,000.

You can still file the return on time under the extension.

But that doesn't mean the $10,000 was not due until October.

Interest may have been accumulating on the unpaid balance since the original payment deadline, and a failure-to-pay penalty may also apply.

That's why I encourage taxpayers not to think of October as their new tax deadline.

It's their new filing deadline.

Then What Is the Point of Filing an Extension?

Because failing to file can make the situation considerably worse.

A properly filed extension generally protects you from the failure-to-file penalty as long

as you ultimately file the return by the extended deadline.

That's important because the penalty for failing to file a return can be much more severe than the penalty for paying late.

So if you aren't ready to complete the return by April, filing an extension is absolutely worthwhile.

Just don't confuse the filing extension with permission to ignore the amount you may owe.

Ideally, you should estimate your tax liability when you file the extension and pay as much of the expected balance as possible by the original deadline.

Should You Make a Payment With Your Tax Extension?

If you expect to owe money, yes, you should seriously consider making an estimated payment with the extension.

You don't necessarily need to know the final tax liability down to the dollar.

That's the whole reason you're extending the return.

But you should make a reasonable estimate based on the information available.

For example, suppose you believe your final balance will be somewhere around $8,000.

Paying that estimated amount by the original deadline can help prevent or reduce additional interest and penalties.

If the completed return later shows that you actually owed $8,500, you're dealing with a relatively small unpaid balance.

That's much different from waiting six months and discovering that the entire $8,500 has been outstanding the whole time.

What If You Can't Afford to Pay the Full Amount?

This is another important distinction.

Being unable to pay your tax bill does not mean you should avoid filing the return.

File the return.

Pay what you reasonably can.

Then deal with the remaining balance separately.

Depending on the circumstances, taxpayers may have options such as an IRS installment agreement or other collection alternatives.

But those payment arrangements are separate from the ordinary extension used to file an income tax return.

The filing extension itself doesn't make the tax disappear, stop interest from accruing, or automatically postpone your obligation to pay.

If You're Currently on Extension, Check Your Numbers Now

If you're sitting on an extension and planning to file in September or October, don't wait until then to find out whether you owe money.

Get an estimate now.

If it looks like you're going to owe and you haven't made a payment yet, paying sooner may reduce the amount of interest and penalties that continue to accumulate.

There are special circumstances in which payment deadlines may be postponed or additional relief may apply, such as certain federally declared disasters or specific statutory exceptions. Those situations are different from the normal extension most taxpayers request.

So the next time someone says:

“I filed a tax extension.”

Mentally add two words:

Filing extension.

Because getting those two words right can make a surprisingly large financial difference.
