Quick Answer
Form 1099-G reports state tax refunds as potential taxable income on your federal return. If you itemized deductions in the prior year and received a tax benefit from state taxes paid, typically 100% of your refund becomes taxable federal income, potentially increasing your federal tax by $220-$370 per $1,000 of refund depending on your bracket.

How Form 1099-G affects your federal taxes
Form 1099-G reports state and local tax refunds, and here's the key rule: if you itemized deductions in the prior year and received a tax benefit from state taxes paid, your refund is generally taxable federal income. This catches many people off guard because they assume refunds aren't taxable.
The logic is simple: if you deducted state taxes on your federal return and reduced your federal tax bill, getting those taxes refunded means you need to "pay back" that federal tax benefit.
Example: $2,000 state refund scenario
Let's say you received a $2,000 state tax refund in 2026 for overpaid 2025 state taxes:
If you're in the 22% federal bracket, that $2,000 refund increases your federal tax by about $440. If you're in the 24% bracket, it costs you $480 in additional federal tax.
The tax benefit rule explained
The amount of your refund that's taxable depends on how much "tax benefit" you received:

How to report 1099-G income
1. Locate the amount: Box 2 of Form 1099-G shows state tax refunds
2. Calculate taxable portion: Use the State and Local Tax Refund Worksheet in IRS Publication 525
3. Report on federal return: Enter taxable amount on Schedule 1, Line 8b ("State and local tax refunds")
4. Keep records: Save your 2025 tax return to prove how much tax benefit you received
Key factors that affect taxability
What you should do
Review your 2025 tax return to determine if you itemized deductions and claimed state tax payments. If you took the standard deduction, your state refund is likely not taxable. If you itemized, use the IRS worksheet to calculate the taxable portion.

Key takeaway: State tax refunds are taxable federal income only if you itemized deductions in the prior year and received a tax benefit from state tax payments. Most refunds result in $220-$480 of additional federal tax per $1,000 refunded.

Key Takeaway: State tax refunds are taxable federal income only if you itemized deductions in the prior year and got a tax benefit from state tax payments.
Taxability of state refunds by prior year tax situation
| 2025 Tax Situation | State Refund Amount | Taxable Portion on 2026 Federal Return |
|---|---|---|
| Standard deduction ($30,000 MFJ) | $1,500 | $0 |
| Itemized, under SALT cap | $1,500 | $1,500 |
| Itemized, hit $10,000 SALT cap | $1,500 | Varies (worksheet required) |
| Itemized, high SALT state | $3,000 | Portion that provided tax benefit |

High earners who likely hit the SALT deduction cap and face complex 1099-G calculations
SALT cap complications for high earners
As a high earner, you're likely hitting the $10,000 SALT (state and local tax) deduction cap, which makes your 1099-G calculation more complex. The key question isn't just "did you itemize?" but "how much tax benefit did you actually receive from state tax payments?"
Example: $150K earner with large state refund
Assume you earned $150,000 in 2025 and paid $12,000 in state income taxes:
The $2,000 of state taxes above the SALT cap provided zero federal tax benefit, so a refund of that portion isn't taxable income.
Multi-year SALT strategy impact
Many high earners bunch SALT payments (pay two years in one year to exceed the standard deduction). If you did this:
State-specific considerations
High-tax states create unique situations:
Key takeaway: High earners hitting the SALT cap need careful worksheet calculations to determine taxable 1099-G amounts, as only the portion providing federal tax benefit is taxable income.
Key Takeaway: High earners hitting the SALT cap must use IRS worksheets to determine taxable 1099-G amounts, as only refunds from taxes that provided federal benefit are taxable.

Remote workers who may have overpaid state taxes to multiple states and received refunds
Multi-state 1099-G complications
As a remote worker, you might receive multiple 1099-G forms from different states, especially if you moved during the year or worked for companies in different states. Each state's refund has different taxability rules for federal purposes.
Common multi-state scenarios
Scenario 1: Moved mid-year
Scenario 2: Remote worker with employer in different state
Example: Multi-state refund calculation
You received:
If you itemized and claimed both states' taxes as SALT deductions:
State reciprocity agreements
Some state pairs have reciprocity agreements affecting 1099-G treatment:
Key takeaway: Multi-state workers may receive multiple 1099-G forms, with each state's refund requiring separate taxability analysis based on which state taxes were claimed as federal itemized deductions.
Key Takeaway: Remote workers receiving multiple 1099-G forms must analyze each state's refund separately, as taxability depends on which state taxes provided federal itemized deduction benefits.
