How to Read W2 Form

Common Misunderstandings
Misinterpretations with W2 forms often stem from confusion about specific box contents or how to use the information within tax returns. Here's how to avoid some of these:
- Misinterpretation of Wages: Ensure you differentiate between gross wages (Box 1) and taxable income, which may differ depending on pretax deductions.
- Multiple W2 Forms: If you had multiple jobs during the year, you'll receive multiple W2 forms and must sum the figures reported.
- Common Tax Codes in Box 12: Familiarize yourself with common codes, such as 'D' for 401(k) contributions, to correctly account for tax-preferred savings.
Practical Example
Imagine you worked part-time at two different companies during the same fiscal year. You'd receive W2 forms from each, reflecting different income amounts and potentially different state tax withholdings if the companies operate in different states. By reconciling the sum of Box 1 from both forms, you'll ascertain the accurate total taxable wages to report on your tax return.
