How to Calculate Withholding
What is Withholding?
A tax withholding calculator helps determine the correct W-4 withholding allowances to avoid owing taxes or receiving a large refund at year end. Under-withholding by $1,000+ may trigger a penalty; over-withholding is an interest-free loan to the government. The IRS Tax Withholding Estimator provides the most accurate guidance.
