Why 43% of Americans Overpay Taxes (And How to Stop)

 

Did you know that 43% of Americans overpay taxes every year? According to IRS data, millions of taxpayers leave money on the table by not optimizing their tax situation. Overpaying taxes might seem like a minor issue, but it can mean losing out on thousands of dollars that could be invested, saved, or used for essential expenses.

Understanding why so many Americans overpay taxes is crucial to avoiding the same mistakes. This guide will explain the key reasons behind tax overpayment, actionable steps to prevent it, and common challenges taxpayers face when optimizing their tax returns.



Why Americans Overpay Taxes

Incorrect Withholding on W-4 Forms

One of the most common reasons Americans overpay taxes is incorrect withholding on their W-4 forms. Many employees fill out their W-4 without fully understanding how it affects their paycheck and tax refund. When too much is withheld, taxpayers end up giving the government an interest-free loan.

Example: John, a software engineer from Texas, realized he had been overpaying taxes for years because he never updated his W-4 after getting married. By adjusting his withholding, he was able to increase his monthly take-home pay by $200.

Missed Tax Deductions and Credits

Deductions and credits can significantly lower tax liability, but many Americans miss out due to a lack of knowledge or poor tax planning.

Commonly Overlooked Deductions & Credits:

  • Student Loan Interest Deduction – Up to $2,500 deduction for student loan interest.

  • Child Tax Credit (CTC) – Up to $2,000 per child, with $1,600 refundable in 2023.1

  • Retirement Savings Contributions Credit (Saver's Credit) – Helps low-to-moderate-income earners save for retirement.

  • Medical Expense Deduction – Eligible if medical expenses exceed 7.5% of adjusted gross income (AGI).

Lack of Tax Planning

Many taxpayers only think about taxes during the filing season instead of planning throughout the year. Without a tax strategy, people miss opportunities to minimize their taxable income.

Example: Lisa, a self-employed graphic designer in California, learned that contributing to a SEP IRA could reduce her taxable income significantly. By planning ahead, she saved over $5,000 on taxes.

How to Stop Overpaying Taxes

Adjust Your W-4 Form Correctly

Use the IRS Withholding Calculator to determine the right amount to withhold. If you’re consistently receiving large refunds, updating your W-4 can help increase your paycheck. 2
