In order to avoid a large balance owing at tax time, it is recommended that you review your payroll details at least once a year to ensure that your federal income tax is withheld at the right level. You can check whether your withholding should be adjusted using the IRS’s Tax Withholding Estimator, available at https://www.irs.gov/payments/tax-withholding.
