Quick answer

IRS Form 4852, Substitute for Form W-2 or Form 1099-R, is the form you attach to your tax return when an employer or payer never sent your W-2 or 1099-R, or sent one that is wrong and will not correct it. You estimate your wages and withholding — usually from your final pay stub — and explain how you calculated the numbers and how you tried to get the missing form. With JustFill you upload the blank IRS Form 4852 PDF, the AI auto-detects every field, you type or dictate your answers, and you download the completed form free.

What is Form 4852?

Employer went out of business, ghosted you, or sent a W-2 with the wrong numbers? IRS Form 4852 is the official substitute for a missing or incorrect Form W-2 or Form 1099-R. You reconstruct your wages, retirement distributions, and tax withheld — your final pay stub of the year is the best source — and file the form attached to your Form 1040 so you can still file on time. Before using it, the IRS expects you to ask the employer or payer for the form and then contact the IRS, which will reach out to the employer for you. JustFill makes the PDF fillable in your browser: the AI auto-detects every field, you type or dictate your figures, and you download the completed Form 4852 free.

Who fills out Form 4852?

  • Employees whose employer never issued a W-2 — for example, a business that closed or stopped responding
  • Workers who received a W-2 with incorrect wages or withholding that the employer refuses to correct
  • Retirees and account holders missing a Form 1099-R for a pension, annuity, or retirement plan distribution
  • Anyone who contacted the IRS about a missing W-2 and still has not received it as the filing deadline approaches
  • Taxpayers reconstructing income from a final pay stub, bank deposits, or other records

Field-by-field breakdown

What each section of Form 4852 asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.

Lines 1–4 — Your information and tax year

Your name, SSN, address, and the tax year the missing or incorrect form covers.

Line 5 — Employer or payer details

The name, address, and TIN (if you know it — check an old pay stub) of the employer or payer who should have issued the form.

Line 6 — Which form this substitutes

Check whether you are substituting for a Form W-2 or a Form 1099-R.

Line 7 — W-2 amounts

Your best estimate of wages, Social Security and Medicare wages, federal income tax withheld, and state/local tax withheld.

Line 8 — 1099-R amounts

For retirement distributions: gross and taxable amounts, distribution codes, and tax withheld.

Line 9 — How you determined the amounts

Explain your source — for example, the year-end figures from your final pay stub or account statements.

Line 10 — Efforts to obtain the form

Describe how you tried to get the W-2 or 1099-R, including contacting the employer or payer and the IRS.

Common mistakes to avoid

  • 1Filing Form 4852 too early — first ask the employer or payer for the form, and if it has not arrived by the end of February, contact the IRS so they can request it on your behalf. Use Form 4852 only when the form still does not show up.
  • 2Guessing wage figures instead of using records — base lines 7 and 8 on your final pay stub, bank deposits, or statements, and say so on line 9. Unsupported estimates invite IRS questions.
  • 3Not amending later — if the real W-2 or 1099-R arrives after you file and the numbers differ, you must file Form 1040-X to correct your return.
