Key takeaways

• Treating taxes as a year-round activity can help avoid withholding errors, missed benefits, and surprise bills.
• Year-round planning can help keep taxes on a steady course and maximize benefits in areas like retirement and healthcare savings.
• Staying organized during the year can make filing simpler and highlight when professional help may be needed.

Many people think about taxes within a narrow window — a few weeks of filing work in winter or early spring before setting them aside until the next year. Yet most results are already locked in by the time those forms are being drafted and submitted.

While tax filing season grabs headlines, tax outcomes can be shaped by dozens of decisions made throughout the year. Choices about income, investments, savings and other areas can quietly determine how much is ultimately owed or refunded.¹

Treating taxes as a year-round consideration doesn’t have to require constant monitoring or aggressive tax strategies. It can involve recognizing the tax implications of financial decisions or key life events — such as marriage, divorce, having a child, changing jobs, or starting a business — and planning accordingly.²

The myth of a fixed ‘tax time’

By treating taxes as a year-round planning activity, tax filers can avoid common mistakes such as under-withholding or over-withholding taxes on income, missing out on tax deductions and credits, or failing to plan for future tax obligations.

Tax filers can also stay better informed about tax law changes that may affect them immediately. Some provisions enacted under the One Big Beautiful Bill Act apply to 2025 taxes, including a higher state and local tax (SALT) deduction cap, new deductions on car loan interest and for tipped workers, and an increased child tax credit.

Paying attention to taxes throughout the year can also help with budgeting and cash flow management. Keeping tax obligations on a steady course can help avoid a large bill or refund the following year.

Year-round tax planning can involve tasks like:

• Updating or aligning withhold taxes after life events or job changes
• Pausing to consider tax impact before major financial moves, like selling investments
• Maximizing contributions to tax-deferred retirement or healthcare savings accounts

Avoiding the ‘set and forget’ mindset

The IRS says it’s important for everyone to distinguish between seasonal filing and ongoing tax planning.  Because federal taxes operate on a pay-as-you-go basis, most taxes must be paid throughout the year as income is earned.³

Withholding. Paycheck withholding isn’t a set-and-forget choice. Changes in income or household circumstances like getting married or having a child can affect how much tax should be paid during the year. Small adjustments to a W-4 form early can prevent large corrections later. Periodically checking withholding can help ensure that enough tax is being paid throughout the year. The IRS Tax Withholding Estimator can help align withholding with actual tax obligations.⁴

Estimated taxes. Filers with other sources of income or who are self-employed may need to make estimated tax payments on a quarterly basis. Those taxpayers can also benefit from strategic timing of income recognition and expense deductions

Adjusted gross income. Understanding adjusted gross income (AGI) is another key part of year-round planning. Your AGI includes all sources of gross income minus specific adjustments including retirement contributions, student loan interest, and certain self-employment expenses to name a few.  Because AGI influences tax rates and eligibility for many types of deductions, making income or contribution adjustments during the year can help manage taxes owed.

Why coordination and year-round planning matter

Many of the most effective ways to manage AGI depend on decisions made well before filing season. Making pre-tax contributions to a retirement account or health savings account, paying student loan interest, or deducting self-employed retirement contributions or business expenses can all help reduce taxable income for the following year.

Healthcare accounts. Health savings accounts (HSAs), flexible spending accounts (FSAs), and health reimbursement arrangements (HRAs) can reduce taxable income while helping households plan for immediate and future healthcare costs. But each vehicle has different rules, usage requirements, and contribution limits.

Retirement accounts. Contributions to traditional IRAs, 401(k) plans, and other tax-advantaged retirement accounts can reduce current tax liability while potentially building long-term wealth. However, maximizing benefits also requires careful attention to contribution limits, eligibility requirements, and the timing of contributions.

Investments. For other taxable individual investments, tax-loss harvesting and the timing of capital gains and losses can impact tax liability. Those strategies require ongoing monitoring and adjustment based on market conditions and individual circumstances.

Charitable giving. The timing and structure or charitable donations throughout the year can also have a big impact on taxes. For some taxpayers, bundling contributions or using specific vehicles can be tax efficient and beneficial to giving goals.

Better organization means less stress

Staying organized throughout the year can help ease stress when it is time to file taxes. Keeping good records — whether through digital tools or clearly labeled folders — provides better clarity of tax and financial pictures as they develop rather than after the fact.

Establishing regular habits also can reduce the last-minute burden of reconciling disorganized information — and give taxpayers greater confidence in the process. As a result, actual filing can be more straightforward.

Maintaining year-round habits may also make it easier to recognize complex situations, and whether it makes sense to consider professional help before the pressure of filing season and looming deadlines.

Final thoughts

For individuals, year-round tax awareness doesn’t have to be about perfection or constant oversight. It’s about staying aligned as life changes and financial decisions are made, making tax filing season a confirmation of choices already made rather than a last-minute frenzy.
