Divide last year's refund (or amount owed) by the number of pay periods in a year to find how much less (or more) should be withheld from each paycheck to bring next year's result closer to zero.
Per-Paycheck Adjustment = Last Year's Refund รท Number of Pay Periods
A large tax refund means you had too much withheld from your paychecks throughout the year, effectively giving the government an interest-free loan of your own money that you get back later with no interest earned. While a refund feels like a bonus when it arrives, the same total money spread across your paychecks throughout the year could have been earning interest in a savings account or used to pay down debt sooner.
Employees can update their withholding at any time by submitting a new Form W-4 to their employer. The form allows adjustments through entries for dependents, additional income, deductions, and an extra withholding amount per pay period, which can be used to fine-tune withholding either up or down based on your actual tax situation.
Because income, deductions, and life circumstances (a new job, marriage, a new dependent) can change during the year, hitting exactly zero owed or refunded is difficult in practice. Most people aim for a small, manageable refund or balance due rather than a precise zero, since a modest miss in either direction carries little real cost.
If adjusting toward a lower refund, it's worth being cautious not to swing too far and end up owing a large amount, which can trigger an underpayment penalty if the shortfall exceeds IRS safe harbor thresholds. Making moderate adjustments and revisiting withholding periodically, rather than one large change, helps avoid this risk.
A large refund means you overpaid taxes throughout the year and gave the government an interest-free loan of your own money. Many financial advisors suggest adjusting withholding to bring the refund closer to zero, so that money is available in your paycheck throughout the year instead.
You can submit a new Form W-4 to your employer, adjusting entries like additional withholding amount, dependents, or other income to change how much tax is withheld from each paycheck going forward.
Owing a large amount at tax time can trigger an underpayment penalty if your withholding and estimated payments fell significantly short of what was owed. It's worth adjusting gradually rather than swinging from a large refund to a large balance due.
