Introduction
A state income-tax refund is reported through Schedule 1, Part I, line 1 of the 2025 Form 1040, then carried into total income. But getting a Form 1099-G doesn't mean the refund is taxable. Many filers struggle with whether that refund is taxable income at all.
The federal question is whether deducting state and local income taxes in the earlier year reduced your federal tax. If it didn't, you may owe nothing on the refund.
This guide covers where the refund goes, when it's taxable, how to work out the taxable portion, and what to do when paperwork is wrong or missing. It covers the 2025 return filed in 2026 and applies to US federal returns, including those of Australian-based taxpayers with US filing obligations.
Always confirm line numbers against the instructions for the year you're filing.
Key Takeaways
- Use the 2025 Schedule 1, line 1, not a line number from an older return.
- Standard deduction in the payment year generally means no taxable refund.
- Itemizing may make all, part, or none of the refund taxable.
- The SALT cap can shrink the taxable amount below the 1099-G figure.
- Compare Form 1099-G against your prior federal return before reporting.
Where Does a State Tax Refund Go on Form 1040?
Locate the refund information first
Start with Form 1099-G. Box 2 shows state or local income tax refunds, credits, or offsets, and Box 3 shows the tax year they relate to. Compare it with your state's online tax account or mailed notice.
Don't confuse the years. The refund is reported in the year you receive it, even though the underlying tax belongs to an earlier year. A 2024 state refund received in 2025 goes on your 2025 return.
Trace the amount to Schedule 1 and Form 1040
For tax year 2025, the path looks like this:
| Form and line | What it is |
|---|---|
| Schedule 1, Part I, line 1 | Taxable refunds, credits, or offsets of state and local income taxes |
| Schedule 1, line 10 | Additional income total |
| Form 1040, line 8 | Additional income from Schedule 1, line 10 |
| Form 1040, line 9 | Total income |
The flow: Form 1099-G or state records → refund worksheet → Schedule 1, line 1 → Form 1040, line 8 → total income on line 9.
Only the taxable portion goes on line 1. The 1099-G amount isn't automatically what you enter. Tax software usually asks about the refund in an interview and places it for you, but check the resulting form and line yourself.
When Is a State Tax Refund Taxable?
Apply the tax-benefit rule
You include a refund only to the extent the earlier deduction lowered your federal tax. Publication 525 sets out this rule for recoveries.
Hypothetical: you itemized, deducted $6,000 of state income tax, and had no SALT cap issue. A $1,000 refund is fully taxable, because the full deduction produced a benefit.
Standard deduction versus itemizing
- Standard deduction in the payment year: none of the refund is taxable.
- Itemized with state income taxes: all or part may be taxable.
- Itemized but chose general sales tax instead of income tax: none of the income-tax refund is taxable.
The 2025 instructions tie the exclusion to the year the tax was paid, not the deduction you take on the current return.
Deduction limits and partial benefits
The SALT cap can mean you only partly benefited. The cap depends on the deduction year, not the year of the refund.
| Deduction year | SALT limit (MFS half) |
|---|---|
| 2018-2024 | $10,000 |
| 2025 | $40,000, phasing down above $500,000 MAGI |
| 2026 | $40,400, phasing down above $505,000 MAGI |
| 2030 onward (scheduled) | $10,000 |
The 2025 changes come from Public Law 119-21. A 2024 deduction recovered in 2025 still uses the 2024 Schedule A and its $10,000 cap.
For example, you paid $11,000 in state taxes, deducted $10,000, and got a $1,500 refund. Because $1,000 of that tax sat above the cap and gave no federal benefit, only $500 of the refund is taxable. Verify current law before applying any limit to later years.
How to Calculate and Report the Taxable Amount
Review the prior-year federal return
Pull your prior-year return and check:
- Filing status
- Standard versus itemized choice
- Schedule A, lines 5d, 5e and 17
- The final federal tax calculation
The 2025 Form 1040 instructions contain the State and Local Income Tax Refund Worksheet. It tells you whether you got a benefit and how much of the refund counts.
Determine whether it's full, partial, or zero
Use this framework with the worksheet:
- Start with the refund on Form 1099-G.
- Subtract any state tax paid above the deduction actually allowed (the nonbeneficial excess). If the refund doesn't exceed that excess, stop. Nothing is taxable.
- Compare 2024 itemized deductions with the 2024 standard deduction ($14,600 single, $29,200 joint, $21,900 head of household).
- Report the smaller of the adjusted refund or the itemized excess over the standard deduction.
IRS Revenue Ruling 2019-11 shows how the taxable portion can change:
- Taxpayer A paid $9,000, deducted $9,000, got $1,500 back: $1,500 taxable
- Taxpayer B paid $12,000, deducted $10,000, got $750: $0 taxable
- Taxpayer C paid $11,000, deducted $10,000, got $1,500: $500 taxable
Use Publication 525 instead of the simplified worksheet for exceptions such as a refund for a year other than 2024, AMT in the payment year, or a joint state refund without a matching joint federal return.
Handle discrepancies and keep records
- Missing 1099-G: you must still report a taxable refund. Contact the state agency for a copy.
- Incorrect amount: ask the issuing agency for a corrected form.
- Offset or credit: amounts applied to 2025 estimated tax are treated as received in 2025.
Keep the prior federal return, Schedule A, Form 1099-G, state refund notice, worksheet and any correspondence. The IRS generally advises keeping records for 3 years.
Taxpayers with multiple state filings, business income or foreign residency can benefit from a professional review. VJM Global's U.S.-compliant tax professionals prepare Form 1040 and 1040-NR returns for individuals.
Special Situations and Common Reporting Errors
Payments that aren't state refunds
Apply each payment's own rule:
- Unemployment compensation: Form 1099-G, Box 1, not Box 2.
- Federal refund: never income, since federal income tax isn't deductible.
- State refundable credit or rebate: the state's label doesn't control. IRS Notice 2023-56 explains when a credit is a refund in substance.
- General-welfare payments: exclusion requires a governmental fund, a need-based payment, and no compensation for services.
Timing and amended returns
Include a recovery in the year you receive it, only to the extent of the earlier tax benefit. When the refund and the deductible payment fall in the same year, reduce the deduction instead of reporting income. If an earlier return had errors, file Form 1040-X.
Mistakes to avoid
- Entering the full 1099-G amount without checking prior-year benefit
- Using an old Schedule 1 line number
- Treating a state refund tracker as federal reporting
- Assuming every 1099-G amount is taxable
Frequently Asked Questions
Where do state tax refunds go on 1040?
The taxable amount goes on Schedule 1, line 1, flows to line 10, then to Form 1040, line 8. Confirm the line in the instructions for your tax year.
What do refund status messages mean?
Messages depend on the agency's tracker. The IRS uses Return Received, Refund Approved and Refund Sent. Use the official IRS or state tracker rather than unofficial interpretations.
When can I expect a refund in 2026?
Most IRS refunds issue within 21 days of e-filing, though review can delay them. State timing varies; California, for example, says e-filed refunds can take up to 3 weeks. No fixed date is guaranteed.
Is a state tax refund taxable if I took the standard deduction?
Generally no. If you took the standard deduction in the year the tax was paid, the refund isn't taxable. Unusual facts or other payment types can change that.
Do I have to report a state refund shown on Form 1099-G?
Review and reconcile the form first. What you include depends on whether the earlier state-tax deduction gave you a federal benefit, and it can be zero.
