Thousands of IRS employees laid off as tax refund season gets underway
Thousands of IRS employees were laid off, primarily affecting President Biden's expansion hires aimed at tax enforcement on wealthy taxpayers.
Taxpayers often make mistakes when filing their taxes, such as inputting incorrect personal information or making math errors.
Choosing the wrong filing status or claiming ineligible credits can lead to complications with the IRS.
Incorrect bank account information can cause delays in receiving refunds, and forgetting to sign the return can render it invalid.
Regardless of the method used for filing, taxpayers should thoroughly review their returns for any errors before submission.
In baseball, errors are part of the official statistics. Both basketball and football track turnovers because they are often a key factor in determining who winds up with a "W" at the end of the game. With a tip of the Tax Talk cap to Dawn Delia, federal tax attorney at Delia Law, today's column will summarize a half-dozen (aka, six or the number of eggs most consumers can afford lately due to their high prices, but we digress) miscues made by taxpayers when filing their federal tax returns.
1. Inaccurate personal information
One of the most frequent and surprisingly simple mistakes people make when filing taxes is submitting incorrect personal details. This can include entering the wrong social security number, misspelling names, entering the wrong date of birth and more.
'It's easy to mistype a digit or letter, especially when using tax software or filling out forms manually,' Delia says. 'Additionally, your name on the tax return must exactly match what's on your Social Security card — adding or omitting a middle initial, for example, can lead to confusion.'
Errors in your personal information can delay processing or result in the IRS rejecting your return altogether. Before submitting, double-check all identifying information for you, your spouse and any dependents.
2. Math errors
Math mistakes are still one of the most common errors on tax returns.
'A misplaced decimal point or an extra zero can drastically affect your refund or result in you owing more taxes than necessary,' Delia warns.
Using tax software can help catch some of these errors automatically, because most programs handle the math for you. However, it's still a good idea to manually review your calculations before submitting, especially if preparing your return without professional help.

3. Incorrect filing status
Choosing the wrong filing status can significantly impact your tax return by affecting your tax bracket, credits and deductions. For instance, some individuals mistakenly file as "Single" when they qualify as "Head of Household," which generally offers more favorable tax rates.
Similarly, married couples often struggle with whether to file jointly or separately. Filing jointly usually results in a lower overall tax burden, but in some cases — such as when one spouse has high medical expenses or significant deductions — it may be better to file separately. If you're uncertain about your correct filing status, the IRS offers tools like the Interactive Tax Assistant to help you choose the most appropriate option.
4. Claiming ineligible credits or deductions
Taxpayers often overestimate the deductions or credits they're entitled to, leading to potential red flags on their return. For example, some deductions, like the student loan interest deduction, are income-restricted, so you cannot claim it if you earn above a certain threshold.
Others may mistakenly claim a home office deduction without meeting the strict requirement of using the space exclusively for business purposes. Incorrectly claiming tax credits like the Earned Income Tax Credit or the Child and Dependent Care Credit can result in penalties, interest charges, inability to claim the item in a future year, oreven an IRS audit.
5. Wrong bank account information
Direct deposit is the quickest way to receive your refund, but entering the wrong bank account number can create major delays — or, even worse, send your refund to the wrong person!
'A single wrong digit can direct your refund to a different bank account, and trust me, recovering it will be a time-consuming ordeal,' Delia warns.
If the IRS detects that the bank information provided doesn't match what it has on file for you, it might revert to mailing a paper check, which could take weeks or months to arrive. Always double-check your bank routing and account numbers before filing, especially if you've recently changed banks or accounts.
6. Forgetting to sign the return
If you're filing a paper return, forgetting to sign it is an easy but costly mistake — your return will be considered invalid, which means it won't be processed until you correct the oversight.
For joint filers, both spouses must sign the return. This rule applies whether you file electronically or by mail.
'E-filing systems generally prompt you to give a digital signature, but it's easy to overlook this step if you're filing manually,' Delia says.
All the correct signatures must be in place before sending your return to the IRS. If you're filing jointly and one spouse is unavailable or unable to sign, you can use a power of attorney or other legal document to complete the process.
Ken & Klee's Tax Notebook
Dawn Delia offers two other potential checklist items to consider when finalizing your return:
■ The first is filing the return too early. Filing before you've received all the necessary forms can lead to mistakes, such as omitting income reported on late arriving 1099s. Make sure you compare your information to prior years as a check and have all your tax documents in hand, including anything related to new situations, before filing to avoid having to amend your return later.
■ The second mistake is missing out on deductions. As mentioned above, some people may overreach and include deductions to which they are not entitled, and the opposite can occur as well. Many people are eligible for deductions, but they either forget to claim or aren't certain they can, so they leave them out for safety's sake. If you rush through the process or aren't familiar with all the tax breaks you qualify for, you could end up paying more than you need to to Uncle Sam. Tax software or consulting with a tax professional can help ensure you're not missing out on savings.
So, whether using tax software, a tax professional or an old-fashioned method, remember that ultimately the buck stops with you, not the tools or people you are using to assist you. Be sure to give your return an "at 5,000 feet" or overall review and consider all of the above possible errors before filing!

Elon Musk Has Benefited From DOGE Cuts but Have the Rest of Americans? Experts Weigh In
Elon Musk's Department of Government Efficiency (DOGE) has claimed massive savings while facing criticism for potentially benefiting the billionaire personally. Congressional reports estimate Musk's companies avoided $2.37 billion in potential liability through DOGE's regulatory changes this year. For You: Read Next: Meanwhile, everyday Americans face increased delays and diminished access to essential services, according to finance expert Andrew Lokenauth, founder of A Senate subcommittee investigation revealed how DOGE cuts have disproportionately benefited Musk and his business empire. According to the minority staff report, Musk's companies faced 25 federal investigations before Trump took office. The report estimated Tesla alone faced $1.19 billion in potential liability for allegedly misleading autopilot statements. Check Out: The Congressional analysis further revealed that Musk put pressure on the head of the Federal Aviation Administration (FAA) to resign before Trump's inauguration. This could be because in September 2024 the FAA suggested several fines totaling $633,009 against SpaceX for license infractions. The FAA also tried to dismiss regulators overseeing Musk's economic interests. However, Musk can't be held accountable for this action because his status as senior advisor shields him from scrutiny that cabinet members receive. DOGE's website claims $175 billion in total savings since Trump took office, representing over $1,000 per taxpayer. However, analysis by multiple news outlets reveals significant accounting errors and questionable methodology in these calculations. According to The New York Times, earlier DOGE claims included an $8 billion typo for an $8 million contract. The Atlantic reported that verified budget savings stood at just $2 billion after correcting various accounting mistakes. Per a BBC analysis, less than 40% of DOGE's claimed savings include links to supporting documentation. According to CBS News, DOGE's actions may have actually cost taxpayers $135 billion through productivity losses and rehiring. 'There have been sectors where waste was reduced, mainly in outdated bureaucratic processes. Streamlining digital operations or cutting legacy contracts helped modernize tech and defense procurement. A few urban centers even saw faster permit approvals,' said Daniel Ray, national insurance expert and CEO of 'Rural communities and working-class families often get hit hardest. When funding is cut without a backup plan, essential services like mail or healthcare access vanish overnight,' Ray added. Reports from USA Today and the Center for American Progress also confirmed that Americans in some regions are experiencing longer wait times for Social Security and other federal services after staff reductions. Public trust in federal agencies has continued to decline as DOGE's cost-cutting measures reshape government operations. According to a KFF Health Tracking Poll, 61% of Americans opposed major cuts to staff and spending at federal health agencies. Moreover, 54% said the Trump administration and DOGE have gone too far with recent reductions. The same survey found that most Democrats and independents see the cuts as reckless, while a majority of Republicans support the changes as necessary for efficiency. 'Some see the cuts as needed tough love, while others see neglect. The mixed signals make it harder for people to believe the system works for them, especially when services feel slower or out of reach,' Ray explained. An analysis from the Council on Criminal Justice also warned that funding cuts risk eroding public trust in government, especially when services are reduced or discontinued. Lokenauth said indiscriminate reductions can lead to disruptions, backlogs and a decline in service quality, which further undermines confidence in federal institutions 'Policymakers need to understand fiscal responsibility should never mean sacrificing service. The lesson from DOGE is clear: Cutting costs isn't leadership unless paired with clear improvements and a strategy that protects the vulnerable while fixing what's broken,' Ray said. While DOGE's $175 billion in claimed savings includes contract cancellations and fraud crackdowns, experts argue that the human cost risks overshadowing short-term gains. The true long-term impact of DOGE's cuts on American communities and finances remains under debate, with both positive and negative effects still emerging. The subcommittee report said it does not accuse Musk of illegal activity in his DOGE role. However, according to multiple experts, the concentration of regulatory relief benefiting Musk's companies raises ethical questions. Per ongoing analysis, the true long-term impact of DOGE's cuts on American communities remains under scrutiny.

For new grads looking for green jobs, corporate sustainability may be the only safe bet
In just the first week of his administration, Trump signed a flurry of executive orders prioritizing domestic oil and gas and (once again) withdrawing the U.S. from the Paris Agreement for climate change mitigation. Since then, additional attacks on existing environmental policies have included the administration's cuts to sustainability research funding and its defunding and dismantling environmental agencies like NOAA and FEMA. Most recently, House Republicans voted to pass a budget reconciliation bill that will gut Biden's Inflation Reduction Act, the largest investment in climate change mitigation and adaptation in U.S. history. This comes at a time when young people really want to get involved and take action against climate change: A 2024 LinkedIn survey found that 61% of Gen Z workers say they want to get a green job within the next five years. But while sustainability fields like environmental justice, nonprofit work, climate policy, and climate research are under very significant threats right now, sustainability experts say that young people pursuing corporate sustainability jobs will likely have more luck. Why are corporate sustainability jobs better protected? Some major companies have dropped their sustainability goals: For example, Walmart says it will likely miss its 2025 and 2030 emissions reduction goals, and companies such as Kraft Heinz and Coca-Cola have dropped some sustainability goals. Banking giants such as Citigroup, Bank of America, Goldman Sachs, and Wells Fargo all dropped out of the United Nations-backed Net-Zero Banking Alliance, which aims to reduce the carbon footprints of banks around the world. But according to PwC's 2025 State of Decarbonization report, only 16% of companies are reducing climate commitments, while 37% are strengthening them. Additionally, the number of companies making commitments continues to grow, with nine times the number of companies reporting targets compared with five years ago. In 2023, 93% of Russell 1000 Index companies published a sustainability report, displaying a public commitment to keeping sustainability goals. According to Steven Cohen, program director of Columbia University's master of science in sustainability management program, these commitments aren't just going to disappear. 'Investors are driving the sustainability field first, because they want to know about the environmental risks incurred by corporations,' he says. Additionally, 'even though the U.S. reporting requirements are being reduced, [requirements from the EU or states like California] are not being significantly reduced.' However, even without pressures from the EU and states like California that have stricter climate regulations compared with the rest of the country, Cohen says that public sentiment against climate change is enough to drive companies to stick to their goals. 'People know that the planet is getting hotter. They know that environmental damage is being done, and they want to figure out ways of maintaining the economy without destroying the planet,' he says. 'Lots of people are interested in it, so there's lots of employment.' Cohen says that since around 80% of the students in Columbia's sustainability management master's program go into the private sector, they are not particularly worried about factors like the Trump administration's repeal of the Inflation Reduction Act having an impact on their employment. 'The job market for graduates is holding up pretty nicely, I'd say,' he says. For those interested in entering the sustainability world after graduation, Cohen recommends developing 'any skills that will help you with management and understanding the impacts' of climate change. He particularly recommends learning how to measure the impacts of environmental pollution and remediation. 'Those are objective conditions, and we'll continue to be focusing on that.'

Americans flunk retirement literacy quiz. Here's why it matters.
Most American adults are stumped by basic retirement-related questions. That's according to a new report from the TIAA Institute and the Global Financial Literacy Excellence Center at the George Washington University School of Business. Most quiz respondents bombed, big time, when posed six questions related to Social Security benefits, Medicare coverage, employment-based retirement savings, ensuring lifetime income, and life expectancy in retirement. On average, they answered two out of six questions correctly. But is this surprising? 'Decisions concerning Social Security and Medicare are not that simple and require people to collect quite a bit of information to develop a plan,' said Annamaria Lusardi, co-author of the report and a senior fellow at the Stanford Institute for Economic Policy Research (SIEPR). 'For many people, Social Security and Medicare are not enough, and this is why it is alarming to see that the knowledge of how these institutions work is so limited.' By subscribing, you are agreeing to Yahoo's Terms and Privacy Policy Curious about your retirement know-how? Take the abbreviated quiz below. Many Americans expect Medicare, for example, will cover all of their expenses. 'It's a shock to them that it doesn't,' Surya Kolluri, head of the TIAA Institute, told Yahoo Finance. 'And then it's a further surprise that if their income is high, they'll pay higher premiums for Medicare Part B and prescription drug benefits.' Why financial literacy matters: People who have a grip on retirement concepts are more likely to have a better shot at not outliving their money. It's no wonder many of us fall short. Only about 28 states have financial literacy requirements for high school students to graduate. It's typically a one-semester course covering topics like budgeting, saving, and managing debt. The real trouble begins when someone starts a job. Waiting to start a retirement savings account even for a year or so has lifelong consequences in terms of saving for retirement. Can you say compounding? 'One of the places that could make an impact is if employers were to offer this education when young adults join the company,' Kolluri said. 'It's a perfect time." It's good to know how many years you have to save for. Only a third of Americans knew that, on average, in the US a 65-year-old man will live about 19 more years to age 84 and a 65-year-old woman about 22 more years to age 87, according to the report. Learn more: How much should I have saved by 50? Having a bead on how many years you might potentially need to finance after you step away from the workforce is key, Michael Finke, professor of wealth management and director of the Granum Center for Financial Security at The American College of Financial Services, told Yahoo Finance. 'Those who understand average longevity are 54% more likely to plan for spending into their 90s and delay tapping Social Security checks,' Finke, who is the co-author of a new study focused on financial planning for longevity, said. 'Those who had an unrealistically low expectation of retirement longevity were far more likely to indicate that they plan to claim Social Security income benefits before the age of 65,' he added. Read more: What is the retirement age for Social Security, 401(k), and IRA withdrawals? 'The main hurdle for people to answer these questions correctly is they haven't sat down and thought about what they'll need in retirement and what the situation might look like,' Jeremy Burke, a senior economist at the University of Southern California's Center for Economic and Social Research, told Yahoo Finance. 'As people get closer to retirement, they tend to pay a little more attention to it. It's a big ask for a lot of folks to try to think about in 30 years what their financial situation's going to look like.' He's spot on. I certainly didn't give it a passing thought and have been open about cashing out an employer plan when I was 30, paying the penalty and tax, and never looking back. That is until now, when I muse about what that might be worth today. Generally, people become more knowledgeable about finances as it becomes more germane. 'Decisions like whether I should put money away in an Individual Retirement Account (IRA) become relevant when you have enough money to set aside in an IRA, or when you get your first job and are making the decision about how much to save in a 401(k),' Finke said. 'It only becomes salient when we're forced to see the relevancy of that choice in our own lives.' Learn more: What is a 401(k)? A guide to the rules and how it works. Then, too, for the most part many people save for retirement these days in default investments like target-date funds which don't require any knowledge of the financial wizardry behind them. Nearly 7 in 10 of workers save in automatic investments in their employer-provided accounts that don't require that they do anything, Finke said. 'In essence, when it comes to retirement savings, we've bubble wrapped the worker experience when it comes to saving.' That is a good thing in many ways, but sticky stuff comes when they invest outside of their 401(k), and are prone to making investment mistakes because they're not as knowledgeable as they need to be, he tripping point in retirement planning is that when people think about whether they have saved enough for retirement it's all about focusing on their number, Finke said. 'That's the total amount of savings that you have in your retirement account, but that number really doesn't mean anything to anybody because it's so difficult to translate the number into a lifestyle.' I agree. Being a 401(k) millionaire sounds like heady stuff, but what does that really mean when you might have three decades of living costs post-retirement? "Simply saying that people are too stupid to make good financial decisions is not the right way to go about helping people make better choices,' Finke said.
