Summary
W2 and W4 forms are essential components of payroll and tax compliance, but they serve very different purposes. The W4 is completed by employees to determine how much federal income tax is withheld from their paychecks, while the W2 is issued by employers to report total earnings and taxes withheld at year-end. Understanding how these forms work—and handling them accurately—helps employers avoid compliance issues and ensures employees are properly prepared for tax season.
