A recovery — a refund or reimbursement of an amount deducted earlier — is governed by the prior benefit. A state or local income-tax refund is generally included in income when the tax was deducted in an earlier year; the refund worksheet starts from the Form 1099-G amount but never above the prior Schedule A deduction, and a list of exceptions can shrink or erase the inclusion. Federal income-tax refunds are never included, because federal tax is never deductible.
The benefit is measured against the standard deduction the taxpayer could actually have taken. A married taxpayer filing separately whose spouse itemized had a standard deduction of zero, so every itemized dollar gave a full benefit and a later state refund is included up to the tax deducted, even when the itemized total was below the ordinary standard deduction.
The same benefit logic reaches beyond refunds. Medical expenses deducted one year and reimbursed the next may return to income in whole or in part. The 1099-G itself arrives by January 31 with a copy to the IRS, so the return must match the document or explain the difference through the worksheet. A taxable refund is figured through the State and Local Income Tax Refund Worksheet and entered on Schedule 1, line 1. Where the taxpayer could choose between deducting state and local income taxes or general sales taxes, the maximum refund includible is limited to the excess of the tax chosen over the tax not chosen.
Recoveries of non-itemized items follow the same benefit principle as refunds: a recovery is includible to the extent the earlier payment produced a tax benefit. Track what was deducted, what was recovered, and what tax benefit the deduction produced; the inclusion never exceeds the benefit.
Worked example
Dee deducted $6,000 of state income tax for 2024 and receives a $1,200 state refund in 2025 documented on Form 1099-G. She generally includes the $1,200, figured through the refund worksheet. Had she taken the standard deduction in 2024 with no tax benefit from the payment, the worksheet would show no inclusion. Her $900 federal refund stays out entirely.
