Many taxpayers expect a refund when filing their taxes, only to find out they owe money instead. This unexpected bill can be frustrating, but it often comes down to changes in income, deductions, or tax withholding. Several factors could be at play if you’re self-employed, had investment gains, or didn’t withhold enough throughout the year.

1. Changes in Withholding

If your employer doesn’t withhold enough taxes from your paycheck, you may end up owing at tax time. This often happens when you adjust your W-4 form to increase take-home pay but don’t account for the tax impact. A job change, raise, or switching from a salaried position to contract work can also affect withholding.

2. Self-Employment and Gig Work

3. Additional Income Without Withholding

Extra income from side jobs, rental properties, or investments can increase your tax liability if no taxes were withheld. Unlike wages from a traditional job, where employers automatically deduct taxes, freelance work, rental income, dividends, and stock sales often don’t come with automatic withholding.

4. Fewer Tax Deductions

5. Reduced Tax Credits

6. Capital Gains from Investments

Selling stocks, real estate, or other investments for a profit can trigger capital gains taxes, increasing what you owe. The tax rate depends on how long you held the asset. Short-term capital gains (on assets held for a year or less) are taxed at the same rate as ordinary income, which can be significantly higher than long-term capital gains, which have lower tax rates.

7. Early Retirement Withdrawals

Many taxpayers don’t realize that the default withholding on early distributions may not cover the full tax liability, leaving them with a balance due when they file. Unless the withdrawal qualifies for an exemption, tapping into retirement savings early can significantly increase the amount of taxes owed.

8. Underpayment Penalties

Failing to pay enough in taxes throughout the year can result in an underpayment penalty from the IRS. This often affects self-employed individuals, freelancers, and investors who don’t make estimated tax payments or employees who don’t withhold enough from their paychecks.

9. Tax Law Changes

Tax laws and regulations change regularly, sometimes increasing tax liability for certain taxpayers. Adjustments to tax brackets, deduction limits, and credit eligibility can result in owing more if you didn’t adjust your withholdings accordingly.

For example, if the standard deduction increased but certain itemized deductions were reduced, you might not be able to lower your taxable income as much as in previous years. Tax law changes can also affect business deductions, child tax credits, and retirement contribution rules, which may lead to an unexpected tax bill for those unaware of the updates.

10. Marriage or Divorce

A change in filing status due to marriage or divorce can have a major impact on your tax situation. If you get married, your combined income may push you into a higher tax bracket, especially if both spouses earn high wages.

On the other hand, divorce can lead to losing valuable tax benefits, such as the married filing jointly status, dependent-related credits, or the ability to claim deductions like mortgage interest on a shared home. Spousal or child support payments may also affect your tax liability, depending on recent tax law changes. Without adjusting withholdings or estimated payments, these changes can lead to an unexpected tax bill.

Your Options

Conclusion

Owing taxes can be frustrating, but understanding the reasons behind it allows for better financial planning. Whether it’s insufficient withholding, self-employment income, lost deductions, or tax law changes, being proactive can help you avoid surprises. Adjusting your W-4, making estimated payments, and keeping up with tax law updates can reduce your chances of owing next year.

If you owe on taxes this year you may want to consider professional assistance to see what options are available to you.
