Question: what is the difference between a w-2 and a w-4 tax form?
Answer: What's the major difference between IRS W-2 vs W-4 forms? A W-4 form is completed by the employee and used by employers to calculate how much income tax to withhold. The purpose of the W-2 form is to report how much the employee was paid over the past year and how much tax was withheld.
