Should You File a Tax Extension?

Filing a tax extension is one of the most misunderstood parts of the tax process.

Many taxpayers assume it means you’re late, at risk of an audit, or doing something wrong. But in reality, extensions are not only common. They’re often the smartest move you can make.

In this episode of the Tax Smart REI Podcast, Nate Sosa and Justin Shore break down the myths, realities, and strategies around tax extensions, especially for real estate investors and business owners.

Why Even Tax Pros File Extensions

Let’s start with a surprising fact: Most tax professionals file extensions themselves.

Justin Shore shares that he files an extension nearly every year, and he’s not alone. Even experienced accountants and CPAs often wait until September or October to file their own returns.

Why?

Because once you own businesses, invest in real estate, or deal with more complex finances, your tax situation takes more time to prepare accurately.

And that’s the key theme of this episode: Extensions aren’t about being late. They’re about being accurate.

The Biggest Misconception: “Filing an Extension Means You’re Late”

This is the #1 stigma.

But here’s the truth:

• An extension moves your filing deadline from April 15 to October 15
• It is completely legal and expected
• The IRS receives tens of millions of extensions every year

So no, you’re not late.

You’re simply using the system as intended.

Do Extensions Increase Your Audit Risk?

Short answer: No.

There’s no evidence that filing an extension increases your chances of being audited.

In fact, the opposite argument can be made:

• Rushed returns = more errors
• More errors = higher audit risk

Common audit triggers include:

• Missing income (like a forgotten 1099)
• Incomplete reporting
• Inaccurate filings

Taking extra time to file correctly actually reduces risk.

Why Extensions Are Actually a Good Thing

Extensions give you:

1. More Time for Accuracy

Real estate investors and business owners often:

• Miss documents
• Have incomplete bookkeeping
• Rush to meet deadlines

An extension allows you (and your CPA) to:

• Clean up financials
• Catch missing data
• Ensure everything is correct

2. Better Tax Strategy Execution

Some strategies, like cost segregation or short-term rental loopholes, require time to implement properly.

Rushing can mean:

• Missed deductions
• Incorrect filings
• Lost tax savings

Important: An Extension Does NOT Extend Payment

This is where many people get tripped up.

A tax extension is:

• An extension to file
• NOT an extension to pay

If you owe taxes, payment is still due by April 15.

Understanding the Key Tax Penalties

There are three major penalties to know:

1. Failure-to-File Penalty

• 5% per month of unpaid taxes
• Starts immediately after April 15 if no extension is filed
• Maxes out at 25%

This is why filing an extension is critical. It avoids this penalty.

2. Failure-to-Pay Penalty

• 0.5% per month on unpaid taxes after April 15
• Applies even if you file an extension

You still need to pay something by April 15 to minimize this.

3. Underpayment Penalty

This applies when you don’t pay enough taxes throughout the year.

The IRS expects you to pay taxes in installments via:

• Quarterly estimated payments
• W-2 withholdings

If you wait until April to pay everything, you may still owe penalties.

How to Avoid Penalties (Simple Strategy)

Think of it in layers:

First Line of Defense: Quarterly Payments

• Pay throughout the year
• Avoid underpayment penalties

Second Line: Extension Payment

• Estimate what you owe by April 15
• Make a payment with your extension

Final Step: File Later (Accurately)

• Use the extra time to finalize your return

Even Large Companies File Extensions

This isn’t just a small-business thing.

Justin shares that Fortune 500 companies file extensions every year. Despite having:

• Massive tax departments
• Dozens (or hundreds) of tax professionals
• Billions in revenue

Why?

• Complexity requires time.

If billion-dollar companies need extensions, it’s completely normal that you might too.

What If You’re Getting a Refund?

Good news:

If you’re in a refund position:

• You won’t face failure-to-pay penalties
• Extensions are generally low-risk

This is common for:

• Real estate investors using cost segregation
• Those leveraging aggressive tax strategies

Still, it’s smart to confirm your position before assuming.

Pro Tip: Rolling Your Refund Forward

Here’s a lesser-known strategy:

If you overpay with your extension, you can:

• Apply the refund to next year’s taxes
• Treat it like a Q1 estimated payment

This helps:

• Simplify future planning
• Avoid underpayment penalties next year

Final Takeaways

Let’s simplify everything:

• Extensions are normal and smart
• They do NOT increase audit risk
• They help you file more accurately
• They do NOT extend your payment deadline
• You may still owe penalties if you don’t pay enough

Bottom Line

Filing an extension isn’t a red flag.

It’s a strategic tool, especially for real estate investors and business owners with complex tax situations.

If used correctly, it can:

• Reduce errors
• Improve tax outcomes
• Give you flexibility

And ultimately…

Help you build a smarter tax strategy.
