One scope note. Form 1040 is a U.S. federal tax form. If you live in Australia, use this guidance only if you have a U.S. filing obligation. It does not apply to an Australian tax return.
This guide walks through the process: find Box 2 of Form 1099-G, review your prior-year deduction method, work out the taxable portion, and enter it using the current Form 1040 instructions.
Key Takeaways
- Check whether your prior federal return used the standard deduction or Schedule A.
- Use Box 2 of Form 1099-G, not your federal refund figure.
- Apply the tax-benefit rule before treating any Box 2 amount as income.
- Keep the 1099-G, prior return and your calculation on file.
Understanding Form 1099-G and the State Refund Amount
What Form 1099-G reports
Form 1099-G reports certain government payments, including state or local income tax refunds, credits and offsets. The IRS Form 1099-G instructions label the key boxes:
- Box 1: Unemployment compensation (a different payment category)
- Box 2: State or local income tax refunds, credits or offsets
- Box 3: The tax year the Box 2 amount is for
If amounts relate to more than one tax year, the payer issues a separate form for each year. Report each one on its own terms.
Where to obtain and verify the form
Check your mail, your state tax authority's online portal and any refund correspondence. Delivery varies by state. New Jersey, for example, offers its 1099-G online only, while Kansas provides access through its Customer Service Center.
Compare the payer, tax year, amount and your identifying details against your records. If something is wrong, ask the issuing agency for a corrected form.
Is a State or Local Tax Refund Taxable?
Standard deduction taxpayers
If you took the standard deduction in the year you paid the state tax, you generally got no federal deduction for it. The refund is therefore not federal income. The IRS state refund FAQ says not to include it if you did not itemize.
You may still receive a 1099-G showing a Box 2 amount. Keep it, but the taxable amount can be zero.
Itemized deduction taxpayers
Under the tax-benefit rule, a refund is taxable only to the extent your earlier deduction reduced your federal tax. Receiving a 1099-G doesn't make the full Box 2 amount taxable.
Example: you itemized with $30,700 in deductions against a $29,200 standard deduction, so your excess benefit is $1,500.
- Recover $400 of deducted state tax: the full $400 is taxable
- Recover $2,000: the taxable amount is capped at the $1,500 benefit
Prior-year sales tax elections matter too. If you deducted $10,000 of state income tax instead of a $9,000 sales tax alternative, at most $1,000 of a later refund can be taxable.
SALT limitation and unused deductions
The cap on state and local tax deductions can mean you never got a federal benefit for part of what you paid.
- Old limit: $10,000 ($5,000 married filing separately)
- 2025 limit: $40,000 ($20,000 MFS), phasing down above $500,000 of modified AGI, with a $10,000 floor
If you itemized but your state taxes exceeded the cap, you may not need to include the whole refund. Only the portion tied to a deduction that actually lowered your tax is taxable.
Refunds, credits, offsets and special payments
A refund applied to a later state bill, or offset against another government debt, still appears in Box 2. Apply the same taxability rules you would to a cash refund of that tax.
Other state payments are different. IRS Notice 2023-56 explains that a refundable credit limited to taxes actually paid can be a refund, while one that isn't is generally income. These categories each follow their own IRS rules:
- Disaster relief
- General welfare payments
- Rebates
- Unemployment compensation
Where to Report a Taxable State Refund on Form 1040
Follow the current-year reporting path
For tax year 2025, the taxable amount goes on Schedule 1, Part I, line 1: "Taxable refunds, credits, or offsets of state and local income taxes." Schedule 1 line 10 then flows to Form 1040 line 8.
Line numbers can change. Confirm them against the forms for the year you're filing. Later-year Schedule 1 releases often appear first as drafts, so use only the final form for the year you file.
Report the taxable amount, not the full refund
The 2025 Form 1040 instructions point taxpayers with a 2025 refund of 2024 taxes deducted on Schedule A to the State and Local Income Tax Refund Worksheet. For other tax years or recoveries, see Publication 525.
If the worksheet result is zero or less, none of the refund is taxable. Keep the 1099-G and your worksheet anyway.
Don't confuse state and federal refunds
Your state refund is on Form 1099-G, Box 2. Your federal refund is calculated separately on Form 1040. Never enter the federal figure, or a number from a refund tracker, as state refund income.
E-filing and paper returns
Tax software walks you through the 1099-G and calculates the taxable portion. Still verify the prior-year deduction details it relies on. On paper, use the latest forms and worksheets, not last year's line numbers.
How to Find and Verify the Correct Amount
Gather your records
Collect:
- Form 1099-G
- Your prior federal Form 1040 and Schedule A, if you itemized
- The prior state return and refund notice
- Proof the refund was received, credited or offset
Box 2 gives the refund amount. The prior federal return tells you how much, if any, is taxable.
Apply a simple decision sequence
- Identify the refund year (Box 3) and the year you received it.
- Confirm whether you took the standard deduction or itemized.
- Determine whether the state tax produced a federal benefit.
- Calculate the taxable portion.
- Enter it using the latest IRS instructions.
Treat separate 1099-G forms from different states or agencies individually.
Resolve discrepancies before filing
If a form is missing, wrong, or lists a refund you never received, contact the issuing state agency and request a corrected or duplicate copy. Per the IRS guidance on missing documents, you can still file with the best available information.
A missing form doesn't excuse you from reporting a taxable refund. Keep proof of the actual refund and of your correction request.
When professional review is appropriate
Consider help for:
- Multi-state refunds or cross-border filing
- Amended returns and prior-year itemization questions
- Business-related refunds or IRS notices
VJM Global's U.S.-compliant tax professionals prepare Form 1040 and 1040-NR returns, handle multi-state obligations and help compile documents when an IRS notice arrives. This applies to U.S. filings only, not Australian tax advice.
Common Situations and Filing Mistakes to Avoid
Receiving a 1099-G after using the standard deduction
Don't add Box 2 to income just because the form arrived. Review the prior deduction method first.
Multiple states, offsets or amended returns
Match each refund to the state tax payment it relates to. If one recovery covers more than one year, Publication 525 calls for pro-rata allocation.
An amended federal or state return can change the tax-benefit analysis. Keep a calculation showing why all, part or none of the refund is taxable.
Reporting errors and outdated instructions
Avoid these:
- Entering the federal refund instead of the state refund
- Copying all of Box 2 without applying the tax-benefit rule
- Relying on a prior-year line number
Check the latest Form 1040 and Schedule 1 instructions, 1099-G guidance and state notices before filing. Keep the worksheets that support your tax-benefit conclusion: the IRS general record period is 3 years, and it extends to 6 years if you omit more than 25% of gross income.
Frequently Asked Questions
Do I need to report a 1099-G state or local tax refund?
Review and account for it, but the federal taxable amount depends on whether deducting that state tax gave you a federal benefit. It may be all, part or none.
Which line on Form 1040 reports a state tax refund?
A taxable state refund generally enters on Schedule 1, line 1 for 2025, and flows to Form 1040 line 8. Verify the line for your tax year.
Where do I find my refund amount on Form 1040?
Your state refund is on Form 1099-G, Box 2. The federal refund is calculated on Form 1040 itself and is a separate figure.
Do tax refunds count as income?
Under the tax-benefit rule, a refund may be taxable if you itemized and deducted the tax. It generally isn't if you took the standard deduction.
What if I received a 1099-G but used the standard deduction?
Keep and review the form. The refund is generally not federally taxable because you received no federal benefit from the state tax.
What should I do if my 1099-G is incorrect or missing?
Contact the issuing state agency and request a corrected or duplicate form. Keep proof of the refund and follow current IRS instructions.
