Hi, @info2351.
Box 6 on the 1099-NEC (or other 1099 forms) reflects the state where the income was earned, not the recipient's current state of residence or mailing address.
All income, including out-of-state earnings, is reported on your home state tax return, while a non-resident return is filed for the state where you worked to pay its taxes. Your home state may offer a credit or partial credit for taxes paid to the other state.
In the meantime, you can temporarily change the recipient's address back to the previous one to ensure that the correct address is populated.
For further clarification, you can contact your state's tax authority or review their guidance to ensure you understand the applicable rules and requirements.
If you have any further questions or require additional assistance, please add a comment below. We are here to help.
