Why Tax Myths Stick - and Why They Matter
Tax myths spread because the U.S. tax code is genuinely complex, and most people learn filing habits from friends, family, or half-remembered advice rather than primary sources. For first-time filers, a single wrong assumption can mean missing a refund, underpaying and facing a penalty, or skipping a filing obligation entirely.
The myths below are among the most common ones that trip up new filers. Each one is corrected using current IRS guidance. This article is general educational information - for decisions specific to your situation, consult a qualified tax professional.
For a broader foundation, the Tax Basics hub covers how income taxes work from the ground up.
Myth
I don't earn enough money to need to file a tax return.
Fact
Filing requirements are set by the IRS based on your gross income, filing status, and age - and the threshold may be lower than you expect.
The IRS updates filing thresholds each year. For many single filers under 65, the threshold is tied to the standard deduction, but certain income types - including self-employment income over $400 - trigger a filing requirement regardless of total earnings. If taxes were withheld from your paycheck and you don't file, you forfeit any refund you're owed. Filing is often the only way to claim refundable credits like the Earned Income Tax Credit. Check IRS Publication 501 each year or use the IRS's interactive tool to confirm whether you're required to file.
Myth
Getting a big tax refund means I did my taxes right.
Fact
A large refund means you overpaid your taxes throughout the year - it's your own money being returned, not a reward.
When your employer withholds too much from your paychecks, the IRS holds that overpayment interest-free until you file. A refund feels gratifying, but it represents money you could have had in each paycheck instead. Conversely, owing money at filing doesn't mean you made an error - it may simply mean your withholding was calibrated closer to your actual liability. For a detailed explanation, see why your refund isn't free money. You can adjust your withholding at any time by submitting a new W-4 to your employer.
Myth
Earning more could push me into a higher bracket and leave me with less money overall.
Fact
Tax brackets are marginal - only the income within each bracket is taxed at that bracket's rate, never your entire income.
This is one of the most persistent myths in personal finance. If you move into a higher bracket, only the dollars above that threshold are taxed at the higher rate. Every dollar below remains taxed at the lower rate that applied to it. Earning more will always leave you with more after-tax income. Tax brackets demystified walks through a concrete example showing exactly how marginal rates are applied.
Myth
Filing an extension gives me more time to pay any taxes I owe.
Fact
An extension extends your filing deadline - not your payment deadline. Taxes owed are still due by the original April deadline.
If you file an extension and have unpaid taxes, the IRS will charge interest and potentially a late-payment penalty from the original due date. An extension is useful when you need more time to gather documents or complete a complex return, but it doesn't eliminate the obligation to estimate and pay what you owe by April. If you're unsure how much you owe, a tax professional can help you make a reasonable estimate to submit with your extension request.
Myth
Freelancers and gig workers are taxed the same way as salaried employees.
Fact
Self-employed individuals owe self-employment tax on top of income tax, and are generally required to pay estimated taxes quarterly.
Employees have Social Security and Medicare taxes (FICA) split between themselves and their employer. When you're self-employed, you pay both halves - a combined rate of 15.3% on net self-employment income (up to the Social Security wage base). Because no employer withholds on your behalf, the IRS expects estimated quarterly payments if you'll owe at least $1,000 in tax for the year. Missing these payments can result in an underpayment penalty even if you pay in full when you file. Income types first-time filers forget covers what counts as reportable self-employment income.
Myth
Filing status doesn't really matter - it's just a label.
Fact
Your filing status directly determines your standard deduction amount, your tax bracket thresholds, and your eligibility for certain credits.
Choosing the wrong status - for example, filing as Single when you qualify as Head of Household - can result in a higher tax bill and missed credits. Head of Household filers receive a larger standard deduction and more favorable brackets than Single filers. Married couples may benefit from filing jointly in most cases, but filing separately is sometimes advantageous depending on specific circumstances. What filing status means explains each category clearly so you can choose correctly.
What These Myths Mean for Your Filing Decisions
Getting the facts right isn't just about avoiding penalties - it's about making informed choices. Knowing how refunds actually work, for example, changes how you think about adjusting your W-4 withholding. Understanding marginal tax brackets removes the fear of raises or freelance income "pushing you into a higher bracket."
$1B+
Unclaimed refunds forfeited annually
The IRS has reported that over a billion dollars in refunds go unclaimed each year because eligible filers don't submit a return.
20%
Eligible workers who miss the EITC
According to IRS estimates, roughly one in five eligible workers does not claim the Earned Income Tax Credit each filing year.
15.3%
Self-employment tax rate on net earnings
The IRS sets the combined Social Security and Medicare self-employment tax rate at 15.3% on net self-employment income up to the Social Security wage base.
If you're weighing whether to file on your own or use a professional, the self-filing vs. professional guide lays out the real trade-offs without pushing you toward either option.
First-time filers also frequently overlook income sources that don't arrive with a W-2. Freelance payments, interest income, and side-gig earnings all count - see income types first-time filers often forget for a practical rundown. And if you suspect you're missing credits you're entitled to, why taxpayers miss credits explains the most common reasons billions in credits go unclaimed each year.
