Form 1040

1g — Form 8919 Wages Updated for tax year 2025

What this line means

Wages from an employer who treated you as an independent contractor when you should have been classified as an employee. If you filed Form SS-8 with the IRS (or the IRS otherwise determined you were misclassified) and you did not receive a W-2, Form 8919 calculates the employee share of Social Security and Medicare taxes you owe on those wages.

Does this apply to you?

  • You filed Form SS-8 asking the IRS to determine your worker classification and they ruled you are an employee
  • You received a 1099-NEC but believe you should have been classified as a W-2 employee
  • The IRS issued a determination letter stating you were misclassified by your employer
  • You worked under conditions that meet the IRS employee test but your employer refuses to issue a W-2

Easy to overlook

Form 8919 saves you money compared to Schedule C If you were misclassified and just report the income on Schedule C as self-employment income, you pay both the employer and employee share of FICA (15.3%). Form 8919 lets you pay only the employee share (7.65%) because your employer is legally responsible for the other half. Filing on Schedule C when you should use Form 8919 means overpaying by roughly 7.65% of your wages. 1 [SOURCE: IRS Form 8919 instructions — Uncollected Social Security and Medicare Tax on Wages]

You need a reason code Form 8919 requires a specific reason code explaining why you are filing. The most common is Code A (you filed Form SS-8 and have not received a reply) or Code H (you received a determination from the IRS). Filing without a valid reason code gets the form rejected. 2 [SOURCE: General filing pattern — worker misclassification]

Watch out for this

Reporting misclassified wages on Schedule C instead of using Form 8919. This is the most expensive mistake a misclassified worker can make — it doubles your FICA tax burden and also subjects you to self-employment tax on top of income tax. If you have any basis for claiming employee status, Form 8919 is the correct path.

  • Line 1a — Form 1040 — Regular W-2 wages; Form 8919 wages go on line 1g instead
  • Line 1z — Form 1040 — Total wages; includes Form 8919 wages
  • Schedule SE — Form 1040 — Self-employment tax; Form 8919 replaces this for misclassified wages
