Between misunderstandings about recent tax legislation from the One Big Beautiful Bill Act (OBBBA) and higher capital gains in portfolios, many Americans unknowingly underpaid their taxes throughout the year. The result? A painful surprise in April.
Why refunds turned into tax bills
One of the biggest drivers was withholding. Many people had too little tax taken out of their paychecks. Even if nothing "changed" in your job, updated tax rules and withholding tables didn't always keep pace with new laws. That gap adds up over 12 months.
At the same time, new deductions and tax benefits from the OBBBA added a layer of confusion that caught many people off guard. On the surface, it sounded simple.
Many taxpayers believed certain types of income, such as tips or overtime, would be completely tax-free. But that's not how it actually works. These benefits come with limits and still require proper reporting.
Tip income, for example, is capped at a $25,000 deduction, while overtime income is limited to $12,500. And these benefits don't last forever. They begin phasing out once income exceeds modified adjusted gross income (MAGI) of $150,000, which means many households see only a partial benefit, or none at all.
For those age 65 and older, the headlines sounded promising. An additional $6,000 deduction was meant to help offset taxes and put more money back in their pockets.
But the reality has been very different for many retirees. Once you factor in investment income, Social Security and pensions, their total income often climbs higher than expected.
Many seniors never received any benefit from this deduction, with eligibility phasing out above MAGI of $75,000.
The biggest tax planning mistake
The most common mistake we see is simple: Reacting instead of planning.
Taxes are not just what happened last year. They're about what you do now to shape what happens next. Even small changes can make a meaningful difference, if you act early enough.
Smart moves to make now for 2026
If you want to avoid another surprise, here are a few high-impact steps to focus on:
1. Update your withholding immediately. If you owed money this year, don't wait. Updating your W-4 now spreads the impact across the rest of the year instead of creating another large bill.
2. Take advantage of tax-advantaged accounts. Health savings accounts, retirement plans and flexible spending accounts can all reduce taxable income while helping you build long-term security. For example, HSA contribution limits increase again in 2026, giving you even more opportunity to save tax-efficiently.
3. Be intentional about investments. Tax-loss harvesting, holding investments longer than one year and being mindful of capital gains can significantly reduce taxes. Short-term gains can be taxed as high as ordinary income, while long-term gains are often much lower.
4. Think strategically about charitable giving. Donating appreciated assets instead of cash or using donor-advised funds can create powerful tax benefits while supporting causes you care about.
5. Don't ignore new tax law changes. Recent legislation introduced new deductions and expanded others, including higher SALT caps and additional above-the-line deductions. But these benefits are nuanced and don't apply equally to everyone. Read the fine print, so that you aren't surprised.
