WASHINGTON – Treasury Secretary Scott Bessent is urging U.S. workers to review and adjust their paycheck withholding now, saying the move can help prevent a surprise tax bill next filing season. The warning, delivered this week in Washington, matters because withholding that is too low can leave workers owing money in the spring, while withholding that is too high can shrink take-home pay all year.
Why the reminder matters now
Paycheck withholding is one of the simplest parts of the tax system, but it is also one of the easiest to get wrong. Employers use the information on Form W-4 and payroll tables to estimate how much federal income tax should be set aside from each check, yet that estimate can drift out of sync when a worker changes jobs, adds a second income, gets married or has a child.
The IRS says employees can update their withholding at any time by submitting a new Form W-4 to their employer. The agency also offers a Tax Withholding Estimator to help workers measure whether their current settings match their expected income, deductions and credits.
How withholding works and where mistakes happen
Withholding is not a final tax calculation. It is an ongoing estimate, built from the information a worker provides and the pay data an employer can see, which means the system does not automatically know about side gigs, investment income, a spouse’s wages or a bonus that pushes annual earnings higher.
That is why tax advisers routinely tell households to revisit withholding after major life changes. The IRS specifically recommends a review after marriage, divorce, the birth or adoption of a child, buying a home, or taking on a second job, because those events can alter a household’s tax picture in ways the original W-4 did not capture.
When withholding falls short, the difference shows up at filing time. The IRS can also assess an underpayment penalty in some cases if taxpayers did not pay enough during the year, especially when the shortfall is large or repeated.
What Bessent’s message signals
Bessent’s advice does not change the tax code, but it does reflect a familiar pressure point for workers and payroll departments. Many households treat refunds as a forced savings plan, yet a refund usually means too much tax was withheld from paychecks in the first place.
For employees who want to avoid a balance due, the safest path is usually modest and deliberate. The IRS estimator is designed for people with multiple jobs, variable pay, pensions or nonwage income, because those situations make a one-size-fits-all W-4 more likely to miss the mark.
Experts say the biggest errors tend to come from people who set withholding once and then never touch it again. That can be risky for workers whose income changed during the year, because payroll systems withhold each paycheck separately and cannot fully account for a person’s total annual tax situation unless the worker updates the form.
Data points and expert guidance
IRS guidance is clear on the mechanics: employees may submit a revised W-4 whenever their situation changes, and the agency’s estimator can help them decide whether to increase withholding, decrease it or leave it alone. That flexibility is important because tax withholding is meant to approximate a year-end bill, not replace the final return.
Tax professionals often point to bonus pay, commission income and gig work as the most common sources of underwithholding. Those earnings can be taxed differently from regular wages during payroll processing, which means a worker can look current on paper and still fall short when the return is filed.
The practical trade-off is straightforward. More withholding usually means a smaller paycheck now and a smaller tax bill later, while less withholding puts more cash in hand today but raises the odds of a payment due next spring. For families managing tight budgets, that choice can matter as much as the refund itself.
What to watch next
The key question is whether Treasury turns Bessent’s advice into a broader public campaign before year-end, especially if tax season messaging starts to target workers with multiple incomes or changing family circumstances. Employers and payroll providers may also see more W-4 updates if the warning prompts households to check their settings sooner rather than later.
For readers, the immediate takeaway is simple: review withholding before the calendar turns, not after the return is filed. The workers most likely to feel the impact next spring are the ones whose pay, family status or side income changed during the year and never made it into payroll records.
