Understanding the W2 (2024)

What is a W2?

Form W2, the Wage and Tax Statement, is the document that shows:

All of the taxable earnings an employee received during a calendar year.

Taxable earnings are the earnings that are subject to taxes after any pre-tax deductions have been deducted from an employee’s gross pay.

Copies of this document are sent to the employee, who is responsible for filing this document for tax purposes.

What are Pre-Tax Deductions?

Section 125 of the IRS code allows employees and employers to take some specific deductions out of an employee’s gross pay BEFORE taxes are calculated. These deductions are:

  • Medical

  • Supplemental Life and Disability Insurance

  • Dental

  • Flex Spending Deductions

  • Vision

  • HSA Deductions

  • 401k (is a pre-tax deduction for federal and state tax withholding calculations only.)

  • Federal Income Taxes– All Section 125 deductions come out of an employee’s check BEFORE taxes are calculated.

  • Social Security and Medicare– Medical, Dental, Vision, Supplemental Life and Disability Insurance, Flex Spending Deductions and HSA Deductions deductions may come out of an employee’s check BEFORE taxes are calculated.
