Form 1099-G (2010) Paper-Filing Checklist
Purpose and Overview
Payers must file Form 1099-INT if they pay interest of $600 or more on state or local income tax refunds reported in Box 2. For interest payments below $600, payers may choose to enter the amount in the blank box on Copy B of Form 1099-G with an appropriate designation such as "Interest Income."
You must report all interest as taxable income on your federal return, regardless of whether the payer issues Form 1099-INT or includes the amount on Form 1099-G. Interest remains taxable even when the underlying refund itself is not taxable due to non-itemization in the prior year.
Unemployment Compensation Reporting
You must combine all Box 1 amounts from every Form 1099-G received and report the total on the unemployment compensation line of your tax return. Each spouse must calculate taxable amounts separately when filing jointly, as the payer tracks unemployment benefits individually.
If you made contributions to a governmental unemployment insurance or paid family leave program in 2010, the payer must issue a separate Form 1099-G showing those payments. Taxpayers who itemize deductions may deduct contributions on Schedule A as taxes paid, while non-itemizers include only amounts exceeding their contributions in gross income.
State and Local Tax Refund Taxability
Box 2 reports state or local income tax refunds, credits, or offsets you received during the calendar year. These amounts are taxable only if you deducted state or local income tax paid on Schedule A in the year to which the refund applies.
You must report the full Box 2 amount even if the state credited it to your estimated taxes rather than sending you a cash refund. Taxpayers who did not itemize deductions in the applicable year do not report Box 2 as taxable income.
Tax Year Identification in Box 3
Box 3 identifies the specific tax year for which the Box 2 refund was made. The payer leaves Box 3 blank only when the refund applies to the 2009 tax year.
If the refund applies to any other year, the payer enters the four-digit year in Box 3 using the format "YYYY", such as 2008 or 2007. Payers must issue separate Forms 1099-G when refunds apply to multiple tax years, showing each year's refund on its own form.
Trade or Business Income Classification
Box 8 contains a checkbox that indicates whether Box 2 amounts are attributable to an income tax applying exclusively to trade or business income. When Box 8 is marked, the refund does not result from a tax of general application, such as regular state income tax.
You must report Box 8-marked amounts on Schedule C, Schedule C-EZ, or Schedule F rather than on the general state tax refund line of Form 1040. This classification applies to specialized taxes on unincorporated business net taxable income or similar trade-specific levies.
Alternative Trade Adjustment Assistance Payments
Box 5 reports Alternative Trade Adjustment Assistance payments of $600 or more that you received under the Demonstration Project for Alternative Trade Adjustment Assistance for Older Workers. You must include all Box 5 amounts on the "Other income" line of Form 1040.
Federal Income Tax Withholding
Box 4 shows federal income tax withheld through backup withholding or voluntary withholding on unemployment compensation, Commodity Credit Corporation loans, or certain crop disaster payments. The backup withholding rate for 2010 is 28 percent when you fail to provide your taxpayer identification number to the payer.
You must include Box 4 amounts on your tax return as federal income tax withheld, typically on the withholding line corresponding to the income type reported in Box 1 or Box 5. Voluntary withholding occurs when you request federal tax withholding from unemployment compensation to avoid underpayment penalties.
Agricultural Payment Reporting
Box 7 reports taxable Department of Agriculture payments or nominee payments that are attributable to you as the actual owner. You must report Box 7 amounts on Schedule F or follow the instructions in Publication 225 for agricultural income reporting.
Partnerships report Box 7 amounts on Form 8825 rather than on Schedule F. Box 9 reports market gain associated with the repayment of a Commodity Credit Corporation loan, whether repaid using cash or CCC certificates, and requires reporting on Schedule F.
Energy Grants and State Withholding Information
Box 6 reports taxable federal, state, or local government energy grants administered through programs providing subsidized energy financing or grants for energy conservation or production projects. You must include Box 6 amounts as ordinary income on your 2010 tax return.
Boxes 10a and 10b report the state identification number and state postal abbreviation for optional state reporting purposes. Box 11 reports state income tax withheld from unemployment compensation shown in Box 1, which you reconcile with your state income tax return and attachments.
Interest on State and Local Tax Refunds
Payers must file Form 1099-INT if they pay interest of $600 or more on state or local income tax refunds reported in Box 2. For interest payments below $600, payers may choose to enter the amount in the blank box on Copy B of Form 1099-G with an appropriate designation such as "Interest Income."
You must report all interest as taxable income on your federal return, regardless of whether the payer issues Form 1099-INT or includes the amount on Form 1099-G. Interest remains taxable even when the underlying refund itself is not taxable due to non-itemization in the prior year.
