Updated: 6 days ago

Facing an Unexpected Tax Bill? Let’s Break It Down


Taxes can throw curveballs—even when you think you’ve done everything right. If your tax bill was higher (or lower) than expected this year, now is the perfect time to assess what happened and take proactive steps for next year. As a CERTIFIED FINANCIAL PLANNER® professional, I help clients navigate tax surprises and optimize their financial strategies to avoid them in the future. Let’s review key areas that may have impacted your taxes and what you can do to plan ahead.

Understand Your Tax Bracket and Adjust Withholding

One of the most common reasons for a tax surprise is a shift in income that pushes you into a higher tax bracket. You might owe more than expected if you earned more this year—perhaps through a raise, bonus, or side hustle. Many taxpayers don’t realize how even a slight increase in income can trigger additional taxes, including higher Medicare premiums or phaseouts of certain deductions and credits. Reviewing your tax bracket each year helps you anticipate potential tax liabilities and take action before the next filing season.

What to do:

  • Use the IRS tax withholding estimator (IRS.gov) to check if your current withholdings align with your income.

  • Adjust your W-4 with your employer if necessary.

  • Consider making estimated tax payments if you have freelance income.


Review Your Investment Tax Strategy


Capital gains taxes can also lead to unexpected tax bills, especially if you sold investments at a profit without tax-efficient planning. Many investors don’t realize that short-term capital gains (on assets held for less than a year) are taxed at ordinary income rates, which can be significantly higher than the long-term capital gains tax rate. Failing to account for these tax consequences can result in an unpleasant surprise when filing your return.

Additionally, if you actively trade stocks, be mindful of the wash sale rule, which can disqualify tax losses if you repurchase the same or substantially identical securities within 30 days before or after the sale. Many investors unknowingly trigger wash sales and miss out on valuable tax deductions.


Steps to take:

  • Tax-Loss Harvesting: Offset gains by strategically selling underperforming investments.

  • Long-Term vs. Short-Term Gains: Holding assets for over a year can result in lower tax rates.

  • Consider Tax-Efficient Accounts: Investing in tax-advantaged accounts like IRAs or 401(k)s can reduce your taxable gains.

Maximize Retirement Contributions


Contributing to tax-advantaged retirement accounts can lower your taxable income while helping you build long-term wealth. Whether you’re employed or self-employed, leveraging retirement accounts is one of the best ways to reduce your taxable income while securing your financial future. Additionally, employer-sponsored plans like a 401(k) often come with matching contributions, which is essentially free money to boost your retirement savings. The tax advantages of Traditional IRAs and Roth IRAs also allow for strategic planning based on your current and future tax brackets.


Key strategies:

  • Max out your 401(k) contributions (limits change annually; check the latest IRS guidelines).

  • Contribute to a Traditional or Roth IRA (eligibility and benefits depend on income levels).

  • If self-employed, consider a SEP IRA or Solo 401(k) for higher contribution limits.

Check for Tax Credits and Deductions


Many taxpayers miss valuable tax credits and deductions that could reduce their tax liability. Understanding which tax benefits you qualify for can make a big difference in your refund or tax owed. Tax credits directly reduce the amount of tax you owe, while deductions lower your taxable income, which in turn lowers your tax bill. Keeping track of eligible deductions throughout the year ensures that you don’t leave money on the table when it’s time to file.


Common tax-saving opportunities:

  • Education Credits: The American Opportunity Credit and Lifetime Learning Credit can help offset education costs.

  • Homeowner Benefits: Mortgage interest and property tax deductions can reduce taxable income.

  • Health Savings Account (HSA): Contributions are tax-deductible and withdrawals for medical expenses are tax-free.

  • Child Tax Credit & Dependent Care Credit: If you have children, these credits can significantly lower your tax bill.

Plan for Next Year’s Tax Strategy


Now is the best time to start preparing for next year. Taking a proactive approach to tax planning can help you reduce your tax burden and make the filing process much smoother. Many people wait until the end of the year to think about taxes, but small adjustments throughout the year can have a huge impact. Whether it’s adjusting your withholdings, tracking deductible expenses, or consulting with a financial advisor, a little planning goes a long way in avoiding tax surprises.


Steps to take:

  • Schedule a mid-year tax checkup with your financial advisor.

  • Track deductible expenses using financial apps or spreadsheets.

  • Review and update your financial plan to align with new tax laws and regulations.
