You generally cannot use only your last pay stub to officially file your federal income taxes, but you can use it to estimate your return or to help complete a substitute form if your W‑2 never arrives.

Quick Scoop

  • The IRS expects you to file using a W‑2 from your employer, not just a pay stub.
  • A last pay stub can be used to estimate your refund or taxes owed and to help complete Form 4852 (a substitute for a missing W‑2), but it is not itself an official filing document.
  • Filing directly from a stub can lead to errors if the year‑end numbers change or if the stub is missing items like your employer’s EIN or correct taxable wages.

Can I file taxes with my last pay stub?

  • For a normal, on‑time return, the IRS requires your W‑2, and tax software is designed around that requirement.
  • Some services or preparers advertise “file with your last pay stub,” but what they really do is create an estimate or prepare a return that should later be matched to your actual W‑2 numbers.

When a last pay stub does come into play

  • If your employer doesn’t send a W‑2 by the end of January and doesn’t respond to your requests, IRS guidance allows you to use Form 4852 (substitute for W‑2), where you use your final pay stub to estimate wages and withholding as accurately as possible.
  • Your final stub is useful because it usually shows year‑to‑date earnings, federal and state tax withheld, and pre‑tax deductions, which you then transfer into the substitute form.

Risks of filing off a pay stub alone

  • A pay stub may not reflect final year‑end adjustments, bonuses, corrections, or the exact taxable wage definitions used on the W‑2, so numbers can be off.
  • Missing details like the employer identification number (EIN) or correct tax boxes can cause your return to be rejected or delay your refund.

Practical tips if you’re waiting on a W‑2

  • Try to get the W‑2 first: contact your employer’s payroll/HR, then the IRS if you still do not receive it after mid‑February, following IRS instructions for missing W‑2s.
  • Use your last pay stub to:
    • Double‑check that the W‑2 numbers look reasonable once it arrives
    • Estimate your refund or balance due early, using tax software’s “estimate” tools
    • Help complete Form 4852 if the W‑2 truly never comes and you need to file.

Bottom line

  • For the exact question “can I use my last pay stub to file taxes”:
    • No for a standard, fully compliant filing—your W‑2 (or a formal substitute like Form 4852) is what the IRS recognizes.
* **Yes, in a limited way** as a basis for estimates and for filling out a substitute form when a W‑2 is missing and you follow IRS procedures carefully.
