I have a tax client that has lost her 1099G 2020 form.

If your client has lost their 1099-G form, which reports unemployment insurance benefits received, they can request a new copy by following these steps:

1. Contact the issuing agency: Your client should contact the state agency that issued the 1099-G form, which is usually the state unemployment insurance agency. They should be able to provide a new copy either by mail or online.
2. Request a copy online: Some state agencies have online portals that allow individuals to request and download a copy of their 1099-G form. Your client should check the website of the state agency that issued the form for any online options.
3. Call the agency: If your client is unable to request a copy online, they can call the state agency and request a new copy by phone. They may be asked to provide personal information to verify their identity.
4. Request by mail: If your client does not have access to the internet or is unable to call the agency, they can request a copy by mail. They should write a letter to the state agency, providing their name, address, and Social Security number, and request a new copy of their 1099-G form.

It may take a few days or weeks for your client to receive the new copy of their 1099-G form, so they should request it as soon as possible to avoid any potential delays in filing their tax return.
