W-2 and W-4

Q. What’s the difference between a W-2 and a W-4?

A. Through my tenure on the IRS IRPAC advisory group, I have learned one great rule, there are thousands of abbreviations and acronyms thrown around the government. Just in payroll there are so many of them that is hard for someone who works in that field to keep them straight, let alone those who are regular employees. You have the W-2, the W-4, the 1099, the I-9, 941, 940, 94X, 2678 and the list goes on. As time goes on, I hope to decode what some of these forms are used for in the payroll world. This is the first issue in that (probably very long-running) series.

Employers use the W-2 to report annual wages paid to their employees. If you have more than one job, you will receive one W-2 per employer. The numbers in those boxes are used by your tax preparer to determine your tax liability. If you are in the company 401(k) or pre-tax medical plan, the gross wage boxes will likely be different. This is ok.

Employees use the Form W-4 to report allowances and filing status to their employer. The numbers you submit will be used by your employer to determine your withholding amounts for Federal income tax only. Social Security and Medicare are calculated as flat percentages and are not affected by your filing status. The Form W-4 is your best tax planning tool. If you work with your CPA or tax adviser on completing this form correctly, you can minimize extra tax due and minimize the refund you receive at the end of the year. Whenever a major life change occurs, make sure you adjust your W-4 values accordingly as quickly as possible.

While they both start with W’s, they have distinctly different uses. Using the correct terminology will make your communication with the payroll department much more efficient and less confusing.
