Tax season is stressful enough, but avoidable mistakes can turn a routine filing into an expensive headache.

With Tax Day just 10 days away, even small errors can mean the difference between a smooth refund and frustrating delays. In some cases, they can even trigger IRS notices or unexpected penalties.

Here are five common filing missteps to watch out for and how to avoid them:

1. Choosing the wrong filing status

Your filing status is one of the most important choices on your tax return because it helps determine your tax rate, your standard deduction and which credits you may be eligible to claim. Pick the wrong one, and you could end up paying more than you owe, getting a smaller refund or triggering delays if the IRS flags the return for review.

For many taxpayers, the confusion comes from life changes that happened during the year, like getting married or divorced, having a child, moving in with a partner, supporting an aging parent or sharing custody. Even if your situation feels straightforward, the IRS rules can be less intuitive, especially for taxpayers who aren’t sure whether they qualify as “head of household” or whether they can still file as “qualifying surviving spouse” after a spouse has died.

Head of household, in particular, can be costly to get wrong. It typically comes with a larger standard deduction and more favorable tax brackets than filing as single – but it has strict requirements tied to paying more than half the cost of keeping up a home and having a qualifying dependent. If you don’t meet the rules and claim it anyway, you may have to pay back tax benefits later, plus penalties and interest.

When in doubt, the IRS has an online filing-status tool, and many tax software programs will walk you through the questions to help you choose the right category.

2. Leaving credits on the table

One of the biggest and most expensive tax-season mistakes is failing to claim every credit or deduction you qualify for. That can mean a smaller refund or a higher bill.

“I think the top mistake people make is not fully understanding or taking the time to really research what are all the different deductions and the ways that you can put a little bit of extra money in your pocket that are available to you,” said Bill Sweeney, senior vice president of government affairs at AARP.

Sweeney also warned taxpayers not to rely on last year’s return as a blueprint for filing because of recent changes to the tax code from the One Big Beautiful Bill Act. 

“This would be a good year given that there are these changes to the tax code, to make sure not to assume that what you did last year will convey over to this year. Really take a fresh look at your tax situation and see if there’s money that you’re leaving on the table,” he said.

3. Missing key deadlines

An extension can buy you time to file your paperwork, but it doesn’t give you extra time to pay. For most taxpayers, the IRS deadline to pay what you owe is April 15, 2026 – even if you request an extension to file later.

“Remember that even if you claim an extension, the money is owed on April 15,” said Mike Faulkender, co-chair of American Prosperity at the America First Policy Institute.

Faulkender, a former Treasury official and IRS commissioner, said taxpayers who need more time should still estimate their bill and pay by the filing deadline to help avoid added costs.

“You have to actually send in a check or have the payment deducted from your account by the filing deadline,” he said.

If you can’t pay in full by April 15, pay what you can to help limit penalties and interest on top of your tax bill.

4. Entering bank account details incorrectly

If you choose direct deposit for your refund, the IRS relies on the routing and account numbers you provide. One wrong digit can lead to delays. 

If you pay what you owe by direct debit, incorrect banking details can also lead to a rejected payment and potentially result in penalties and interest.

5. Filing before all your tax forms arrive

Timing matters when it comes to filing your taxes. Submitting your return before you’ve received all your key paperwork, like W-2s or 1099s, can lead to errors, missing income or a return you have to amend later.

Faulkender said there’s a simple way to double-check what’s been reported under your name before you file.

“One of the things that I learned last year when I was IRS commissioner, was that if you create an account on irs.gov, you can see everything that’s been filed under your tax ID,” he said. 

“We’re supposed to receive all of our W-2s and our 1099 forms in the mail in January and February. But if you’re missing one, or you misplaced it rather than requesting it again, you can actually go and see what was filed under your taxpayer identification number if you create an account on IRS.gov.” 

Filing late can also cost you extra money, especially if you owe. The goal is to wait until you have what you need, then file as soon as you’re ready.

WASHINGTON — Merely two weeks had passed since the Iran war began when Gen. Randy George, the Army’s highest-ranking officer, began sounding an alarm.

Touring a weapons depot in North Carolina, George warned lawmakers present that the conflict’s vast and ever-growing list of targets was straining U.S. capacity — “depleting our stockpiles faster than we can replace them,” as one congressman recalled. Since assuming Army leadership, George had made it his mission to strengthen the nation’s industrial base in anticipation of precisely this moment, when the United States would be engaged in a major war with a formidable adversary.

On Thursday, in a brief phone call, Defense Secretary Pete Hegseth fired George. No reason was given, a U.S. official familiar with the matter told The Times.

The forced departure of George in the middle of a war created yet another blow to morale inside the Pentagon, where multiple officials expressed dismay over the state of the department’s leadership. Over the last year, Hegseth has fired five sitting members of the joint chiefs of staff, with only two holdovers remaining in their posts.

“Whenever you have a change in leadership, military or otherwise, there is bound to be some churn in information management,” one U.S. official said, granted anonymity to speak candidly. “So what you’re doing, in the middle of a war, as we are taking U.S. casualties, is you’re taking out the general in charge of making sure the right people and equipment are flowing into the Middle East.”

Inside the building, officials believe that Hegseth’s next target is Dan Driscoll, the Army secretary and an ally to President Trump. Driscoll has been seen by Hegseth’s aides as outshining the Defense secretary on prominent policy initiatives.

It is a purge that Republican lawmakers on Capitol Hill fear could have tangible, detrimental effects on the war effort. Sens. Roger Wicker of Mississippi, Tom Cotton of Arkansas and Joni Ernst of Iowa, all members of the Senate Armed Services Committee, have expressed private concerns over George’s firing, a second U.S. official said.

Forcing out Army leadership responsible for training and equipping its soldiers, and for ensuring weapons stockpiles continue to meet demand, risks bureaucratic chaos and despair in the ranks at a time when the Trump administration is openly considering a ground operation in Iran.

Others in the Pentagon have raised concern over the U.S. military stockpile, including Air Force Secretary Troy Meink, who last month warned at a defense conference that munitions shortages were a concern even before the war began.

“It was something that we were concerned about even before the operation,” Meink said. “It has just been the fact that we couldn’t see the threat evolving and what we’re facing. So we definitely have to improve on that.”

Trump has denied that the United States faces weapons shortages, even after meeting with the nation’s top contractors last month in a push for them to increase — and on some products, quadruple — their output.

“What interceptors we have for Iran is because of Randy George,” the first U.S. official countered. “He continued to work that problem set up through [Thursday]. It’s a problem set he was working in real time.”

Jerry McGinn, director of the Center for the Industrial Base at the Center for Strategic and International Studies, said U.S. forces have reached a stage in the war where they can pivot away from standoff weapons systems. With Iran’s air defenses largely degraded, they can instead rely on weapons such as laser-guided bombs, helping ease pressure on stockpiles.

But Iran’s downing of two U.S. aircraft on Friday suggests that longer-range weapons may still be necessary.

“When the stockpile is stressed, as it was after Ukraine and then now with Iran, any surge in need leads to a backlog as they try to replenish,” McGinn said.

“The three things they’ve been using a whole lot of are Tomahawks, [Terminal High Altitude Area Defense] and Patriots, and those inventories were already somewhat depleted after Midnight Hammer last summer,” McGinn added. “You can’t crank those out very fast.”

Beyond his role tending to the nation’s “magazine depth” — making sure the military isn’t firing more weapons than it is able to replenish — George also led the Pentagon’s effort to set up a joint task force last year aimed at speeding up the U.S. military’s ability to counter small unmanned aircraft systems, or drones.

The program has proved critical in the war effort. Tehran now relies heavily on its Shahed drones, with its missile production and launch capacity severely diminished.

Acknowledging the Pentagon expulsions, Iran’s embassy in South Africa posted photos on social media Friday x-ing out portraits of several top U.S. military officials fired in recent months.

“Regime change happened successfully,” the Iranians wrote.

The Department of Homeland Security (DHS) on Saturday pushed back on claims by Sen. Chris Van Hollen, D-Md., that ICE agents struck an “asylum seeker,” saying the man is an illegal immigrant who caused a crash while trying to evade arrest.

DHS told Fox News that the man in question is a Honduran illegal immigrant with a final order of removal dating back to 2018.

According to DHS, Immigration and Customs Enforcement (ICE) officers attempted to arrest the individual, identified as Ever Omar Alvarenga-Rios, on Thursday in Baltimore, but he allegedly tried to evade arrest.

When officers conducted a vehicle stop, Alvarenga allegedly failed to comply with law enforcement and “drove recklessly” through the city, DHS said.

DHS claimed that Alvarenga then “slammed on his brakes,” causing a multi-vehicle crash.

He then attempted to flee on foot and ignored law enforcement commands, DHS said, adding that ICE officers “followed their training and used the minimum amount of force necessary to make the arrest.”

DHS said the two officers involved in the incident were injured and taken to the hospital.

“This illegal alien broke our laws, resisted arrest, sent two ICE law enforcement officers to the hospital, and endangered the general public. Thankfully both our officers are expected to make a full recovery,” DHS Acting Assistant Secretary Lauren Bis said in a statement.

“This dangerous attempt to resist arrest comes after sanctuary politicians have encouraged illegal aliens to evade arrest by hosting webinars instructing illegal aliens how to avoid being caught. Sanctuary politicians must stop encouraging this reckless behavior that endangers illegal aliens, our officers, and the public,” she added.

Van Hollen on Saturday posted photos on social media of the man in a hospital bed, describing him as an “asylum seeker” who was rear-ended by an ICE vehicle while driving to work Thursday in Baltimore.

According to Van Hollen, the man suffered “significant injuries to his head, chest, back and hands.”

The Maryland Democrat also said the man was detained and claimed ICE was violating his rights by denying him access to attorneys.

In a statement to Fox News Digital, Van Hollen said that ICE under the Trump administration “continues to prevent Ever Alvarenga from meeting with attorneys while in the hospital — preventing them from receiving full updates on his health condition or discussing his case so that the full set of facts can come to light.”

“They have also blocked him from signing a privacy release so my office can make further inquiries. No matter what the Trump Administration says, the Constitution applies to everyone in the United States,” Van Hollen added. “Mr. Alvarenga has a right to due process and full access to his legal representation. By standing in the way, it looks like the Administration has something to hide.”
