by PaycheckScope Admin
The IRS Form W-4 tells your employer how much federal income tax to withhold. Too little withholding means a tax bill in April; too much means you are giving the government an interest-free loan all year.
Key inputs include filing status, number of dependents, other income, and deductions. After major life events — marriage, a child, a second job — update your W-4 promptly.
Use PaycheckScope to estimate your annual tax liability, then compare it to your current withholding to decide if adjustments are needed.
