Company closed in August 2022 and I can’t get my W-2. How else can I get it

this depends on whether or not they ever filed them.

1) see if the IRS has a transcript  - no transcript means they haven't filed as yet and no one can say if they will. you would want a wage transcript but there is no state info if you need that too

2) have you tried calling the employer

3) if the iRS has a transcript you can get a full copy (state info too) from Social Security Adm

4) Haven’t received your Form W-2 yet? The IRS can help
It’s tax time, and you need your Form W-2, Wage and Tax Statement, to file an accurate
federal tax return. If your employer hasn’t sent you the form yet, contact them and ask
for a copy. Make sure they have your correct address.
If you’re unable to get your Form W-2 from your employer, contact the Internal Revenue
Service at 800-TAX-1040. The IRS will contact your employer or payer and request the
missing form. Let them know:
• your name, address, Social Security number and phone number;
• your employer’s name, address and phone number;
• the dates you worked for the employer; and
• an estimate of your wages and federal income tax withheld in 2016.
You can use your final pay stub to figure these amounts.
If, after contacting the IRS, you still do not have your Form W-2, you have two choices:
1. File your return by the April due date and use Form 4852, Substitute for
Form W-2, Wage and Tax Statement. Try to estimate your wages and
withholding as best you can.
2. Ask for more time to file by using Form 4868, Application for Automatic Extension
of Time to File U.S Individual Income Tax Return. You can even e-file the
request.
If it turns out the information on the Form W-2 is different than you reported, you will
need to file an amended tax return using Form 1040X, Amended U.S. Individual Income
Tax Return, to make the change.
