Common NOL carryback mistakes can kill your IRS refund faster than you can say “cash flow.” And if you’re running a business that just landed a government contract, chances are you’re burning money upfront and counting on that refund to keep things moving.
Look, I’ve been around long enough to see this go both ways. One business owner plays it smart, files their NOL carryback properly, and unlocks $200K in cash from the IRS. Another does it wrong—misses the window, files the wrong form, picks the wrong year—and they’re stuck waiting nine months or more… or worse, they get denied altogether.
Which one do you want to be?
If you’re serious about turning losses into liquidity, you need to know the landmines to avoid. Let’s break down the most common NOL carryback mistakes and how to sidestep them—before they cost you real money.
Why NOL Carrybacks Are a Goldmine (When Done Right)
Before we dive into the mistakes, let’s get clear on why this even matters.
When your business takes a loss—especially while ramping up to fulfill a government contract—you’re probably not feeling great about your bottom line. But what most business owners miss is this: that loss can be used to offset prior-year profits.
Translation? You already paid taxes in those profitable years. Now you get to go back, apply the current year’s loss, and ask the IRS for a refund. This is what’s called a Net Operating Loss (NOL) carryback.
But here’s the deal… the IRS isn’t just handing out checks. You’ve got to file it right. And that’s where things get dicey.
Mistake #1 – Missing the IRS Filing Deadline
You’d be shocked how many smart people fumble this one.
There’s a 12-month window after the year of your loss to file a quick refund using IRS Form 1045. Miss that? You’re stuck filing Form 1139 or worse—waiting until the next tax season just to apply it as a carryforward (which delays your refund for years).
Real Talk from the Field
We had a client—we’ll call him Mike—who took a $600K loss building infrastructure for a state project. His prior accountant told him to wait until tax season. By the time he came to us, that fast-track window had closed.
We still got him a refund, but it took 9 months instead of 6 weeks. You think that didn’t hurt?
Lesson: Deadlines matter. If you’re not on it, you’re out.
Mistake #2 – Picking the Wrong Years to Apply Your Loss
This one’s sneaky. Most people don’t realize that which prior year you apply your NOL to can drastically impact the refund you receive.
Why Year Selection Matters
Let’s say you had profit in 2020 and 2021. If 2021 had higher tax liability, carrying your loss back to that year gets you a bigger refund. But if you blindly apply it to the earliest possible year without analysis, you’re leaving money on the table.
At Icarus Fund, we run a refund-maximization analysis that targets the most lucrative years for carryback. It’s not guesswork—it’s precision strategy.
Mistake #3 – Filing an Incomplete or Incorrect Form 1045
This is where most DIYers and generalist tax folks crash and burn.
Form 1045 requires detailed schedules, calculations, and substantiation of your loss and previous year income. One missing line item? One mismatch in documentation?
Your refund gets delayed. Or worse—denied.
What Icarus Fund Does Differently
We specialize in carryback filings. Every return is scrubbed, cross-checked, and built to be audit-proof. You don’t want the IRS poking around longer than necessary—and with us, they don’t have to.
Mistake #4 – Forgetting About State-Level NOL Rules
Federal and state tax codes aren’t always best friends.
Some states allow carrybacks. Others don’t. Some have different windows or rules. If you assume state law mirrors federal and file accordingly, you could end up triggering a correction letter—or worse, penalties.
Icarus Fund’s Approach
We review both your federal and state tax positions to create a cohesive strategy, not just a refund filing. That means you get every dollar you’re entitled to, with zero surprises.
Mistake #5 – Seeing Your Loss as a Problem Instead of a Weapon
This is the mindset shift that changes everything.
Most business owners treat a loss as something to hide. But when used strategically, that loss can fuel your next move.
Whether you’re hiring a new team, scaling operations, or buying materials to fulfill a new contract, that IRS refund isn’t just a return—it’s working capital. And you earned it.
Case Study – From $500K Loss to $185K Refund
Let me give you a real-world win.
We had a government contractor come to us after taking a $500,000 loss during a rapid expansion year. They’d already paid taxes in 2019 and 2020.
We carried back their loss, selected the right year, and filed a clean Form 1045 with supporting docs. Sixty days later, they had $185,000 in their bank account—cash they used to buy new equipment and front payroll for their next federal job.
That’s what happens when you avoid the common NOL carryback mistakes and let pros handle the playbook.
