The Tax Withholding Estimator is a free tool for workers and retirees to estimate the federal income tax that must be withheld from their paychecks for the upcoming tax year.
For workers earning overtime pay, the bill provides an annual deduction of up to $12,500, while for employees receiving tips, the deduction limit is $25,000.
Seniors aged 65 and older can now claim an annual deduction of $6,000 on their taxes, which is over and above the standard deduction already available to them. Taxpayers who bought cars with loans may be eligible for an annual deduction of $10,000 for the interest paid.
These changes have now been incorporated into the IRS Tax Withholding Estimator to better reflect withholding amounts. The tool also incorporates other related changes tied to charitable giving, homeownership, and family-related credits.
“The estimator guides taxpayers step-by-step through entering income, withholding, credits, and deductions, and takes around 25 minutes on average (less for those with simpler financial situations),” the IRS said.
Besides taxpayers who directly benefit from the One Big Beautiful Bill, there will be others who find the tool beneficial, such as those have more than one job; experience a major life change recently, such as a marriage or childbirth; receive income without automatic tax withholding, when engaged in freelance or gig work, for example; and claim credits such as the Child and Dependent Care Credit or Adoption Credit, the agency said.
“Withholding that closely matches a taxpayer’s anticipated tax liability can help prevent unexpected tax bills and potential underpayment penalties. It can also help taxpayers avoid over-withholding and increase take-home pay throughout the year,” the IRS said.
“To get the most accurate results, taxpayers should gather recent pay statements and a copy of their latest federal income tax return before using the estimator.”
If the individual has other sources of income or plans to itemize deductions, they must also keep on hand the most recent federal tax return, records of expenses in case they plan to itemize deductions or claim adjustments, and payment records for self-employment, gig work, and Social Security.
While provisions in the One Big Beautiful Bill provide benefits to taxpayers, the IRS has chosen not to update some of the related filing processes for the tax year 2025.
Information returns documents, which businesses file with the IRS, report transactions such as wages paid to employees, while IRS withholding tables detail amounts needed to withhold from an employee’s paycheck for taxes, Social Security, and Medicare.
“These decisions are intended to avoid disruptions during the tax filing season and to give the IRS, business, and tax professionals enough time to implement the changes effectively,” the agency said at the time.
