The IRS determined it will not challenge the taxability of payments related to general welfare and disaster relief. This means that people in the following states do not need to report these state payments on their 2022 tax return: California, Colorado, Connecticut, Delaware, Florida, Hawaii, Idaho, Illinois, Indiana, Maine, New Jersey, New Mexico, New York, Oregon, Pennsylvania and Rhode Island. Alaska is in this group as well, but please see below for more nuanced information.

In addition, many people in Georgia, Massachusetts, South Carolina and Virginia also will not include state payments in income for federal tax purposes if they meet certain requirements. For these individuals, state payments will not be included for federal tax purposes if the payment is a refund of state taxes paid and either the recipient claimed the standard deduction or itemized their deductions but did not receive a tax benefit.
