What Is Tax Form 1099-G and How Does It Affect Your Taxes?

Tax Form 1099-G reports payments a government agency made to you during the year, most often unemployment benefits, but also state or local income tax refunds, agricultural subsidies, taxable grants, Reemployment Trade Adjustment Assistance, and Commodity Credit Corporation loan market gain. The IRS gets a copy of every form issued to you, so anything taxable on it needs to appear on your return in the right place. What follows is how to read the form, decide what’s actually taxable, and file without triggering a notice.

What Kinds of Payments Show Up on a 1099-G

Six categories of government payments are reported on this form:1Internal Revenue Service. Instructions for Form 1099-G

  • Unemployment compensation from any federal or state program, including Railroad Retirement Board unemployment and state paid family leave funded through a contributory program.
  • State or local income tax refunds, credits, or offsets from a prior year.
  • Reemployment Trade Adjustment Assistance (RTAA) payments, which are wage supplements for workers displaced by foreign trade competition who take a lower-paying job.
  • Taxable grants, including energy conservation grants and grants from tribal governments.
  • USDA agricultural subsidies.
  • Commodity Credit Corporation (CCC) loan market gain, which is the difference between the original loan rate and the lower repayment amount when a farmer repays a CCC loan.

Federal law requires unemployment compensation to be included in gross income.2Office of the Law Revision Counsel. 26 USC 85 – Unemployment Compensation These payments are taxed at your ordinary income tax rates, the same rates that apply to wages.

What Each Box on the Form Means

Form 1099-G has eleven numbered boxes, and you’ll only see amounts in the ones that apply to you:1Internal Revenue Service. Instructions for Form 1099-G

  • Box 1: total unemployment compensation paid to you during the year.
  • Box 2: state or local income tax refunds, credits, or offsets.
  • Box 3: the tax year the Box 2 refund relates to, if not the most recent year.
  • Box 4: federal income tax withheld, whether backup withholding or voluntary withholding you requested.
  • Box 5: RTAA payments.
  • Box 6: taxable grants, including energy-related grants.
  • Box 7: USDA agricultural subsidy payments.
  • Box 8: a checkbox indicating the Box 2 refund came from a tax that applied only to business income rather than a general income tax.
  • Box 9: market gain from repaying a CCC loan.
  • Boxes 10a, 10b, and 11: state identification information and any state income tax withheld.

Even if you don’t receive a form because a payment fell below the agency’s reporting threshold, you’re still responsible for reporting the income.

When a State Tax Refund in Box 2 Is Actually Taxable

A number in Box 2 doesn’t automatically mean you owe tax on your state refund. This is where most people get tripped up, and the answer depends entirely on what you did on last year’s federal return.

The question is whether you itemized deductions on Schedule A and claimed a deduction for state income taxes paid. If you took the standard deduction, your state refund is not taxable at all. You can only be taxed on the refund if you received a tax benefit from deducting those state taxes in the first place; if you never deducted them, there’s nothing to recapture.3Office of the Law Revision Counsel. 26 USC 111 – Recovery of Tax Benefit Items

Even if you did itemize, the refund still might not be fully taxable. The state and local tax (SALT) deduction is capped at $40,400 for 2026. If your total state and local taxes exceeded the cap, you didn’t get the full benefit from the amount you paid, so only part of the refund, or none of it, would be taxable. Same result if you itemized but deducted sales tax or property tax rather than state income tax: the income tax refund doesn’t create taxable income for you.

The IRS worksheet in the instructions for Schedule 1, Line 1 walks through the calculation. Tax software handles it automatically if you used the same software the prior year. If you’re doing it by hand, don’t skip the worksheet, or you’ll either pay tax you don’t owe or underreport.

Where Each Amount Goes on Your Return

Each type of 1099-G payment lands in a different place:

  • Unemployment compensation from Box 1 goes on Schedule 1 (Form 1040), Line 7, and flows from there to your Form 1040.4Internal Revenue Service. Schedule 1 (Form 1040)
  • A taxable state or local tax refund from Box 2 goes on Schedule 1, Line 1. If it isn’t taxable under the tax benefit rule, you don’t report it at all.
  • RTAA payments from Box 5 go on Schedule 1 as other income.
  • Agricultural payments in Box 7 and CCC market gain in Box 9 go on Schedule F for farmers.
  • Taxable grants in Box 6 depend on the nature of the grant; energy conservation grants typically go on Schedule 1 as other income.

Federal income tax withheld in Box 4 and state tax withheld in Box 11 both count as tax payments already made. Add Box 4 to the federal tax payments section of Form 1040. Miss these entries and you’ll overpay.

Withholding and Estimated Tax on Unemployment

Unemployment benefits don’t come with automatic withholding, which catches people off guard. Collecting benefits for several months without setting anything aside can leave you with a large balance due at filing time plus an estimated tax penalty.

You have two ways to handle it. You can submit Form W-4V (Voluntary Withholding Request) to your state unemployment agency and have 10% withheld from each payment.5Internal Revenue Service. Form W-4V (Rev. January 2026) Ten percent is the only rate available for unemployment withholding; you cannot pick a different percentage. Or you can make quarterly estimated tax payments to the IRS using Form 1040-ES.6Internal Revenue Service. Unemployment Compensation

If 10% doesn’t cover your actual tax rate, estimated payments can fill the gap. For someone in the 22% bracket collecting $15,000 in unemployment, 10% withholding leaves roughly $1,800 still owed. Combining W-4V withholding with a small estimated payment each quarter avoids the year-end surprise.

When You’ll Get the Form, and What to Do If It’s Wrong or Missing

Government agencies must furnish your 1099-G by January 31 of the year after the payment.7Internal Revenue Service. Requirements for Furnishing Information Returns Electronically Most state unemployment agencies offer electronic delivery through an online portal, with an email notification when the form is ready. Paper copies arrive by mail around the same time.

If yours hasn’t shown up by mid-February, log into the state unemployment or tax agency portal to view and download it directly, or call the agency for a duplicate. Even if the form never arrives, you’re still required to report the income; use your own records, bank statements, or payment history from the agency’s portal to reconstruct the amounts and file accurately.8Internal Revenue Service. How to File When Taxpayers Have Incorrect or Missing Documents

If the Amount Is Wrong

Contact the state agency that issued the form and request a corrected 1099-G. Most states run this through their online portal. If you can’t get a corrected form before the filing deadline, report only the amount you actually received and file based on accurate numbers.9Internal Revenue Service. What to Do When a W-2 or Form 1099 Is Missing or Incorrect Keep records of your communications with the agency in case the IRS questions the difference later.

If You Got a Form for Benefits You Never Received

If a 1099-G shows up for unemployment you never applied for, someone likely filed a fraudulent claim using your Social Security number. Report the fraud to the state agency that issued the form. Then file IRS Form 14039 (Identity Theft Affidavit) to alert the IRS your Social Security number has been compromised.10Internal Revenue Service. Identity Theft Affidavit You can submit Form 14039 online through the IRS portal, by fax to 855-807-5720, or by mail; choose one method only.

The IRS also recommends enrolling in the Identity Protection PIN (IP PIN) program after an identity theft incident. An IP PIN is a six-digit number that blocks anyone else from filing a return using your Social Security number. Request one at IRS.gov/ippin.

What Happens If You Don’t Report It

The IRS matches every 1099-G it receives against the corresponding return through an automated system. When the numbers don’t line up, the IRS sends a CP2000 notice proposing changes to your return.11Internal Revenue Service. Topic No. 652, Notice of Underreported Income – CP2000 It isn’t an audit, but it means the IRS thinks you owe more tax, and you’ll need to either agree and pay or explain why the proposed change is wrong.

If the underreported amount is large enough, a 20% accuracy-related penalty applies to the additional tax owed, triggered by negligence or a substantial understatement of income.12Office of the Law Revision Counsel. 26 US Code 6662 – Imposition of Accuracy-Related Penalty on Underpayments Deliberate fraud is a different category, carrying a 75% penalty on the portion of the underpayment attributable to fraud.13Office of the Law Revision Counsel. 26 USC 6663 – Imposition of Fraud Penalty Report everything, even amounts you’re disputing. Filing an accurate return with a note explaining a discrepancy is always safer than leaving the income off.
