I didn’t work 2022 due to on job injury. Do I have to file even though I have no W-2

[NCperson]

if you are filing SINGLE, there is no filing requirement for 2022 if your income was less than $12,950. 

Even though you had no W-2, did you receive other taxable income on a 1099-R? disability payments that were taxable? 

[Opus 17 · Accepted solution]

If you are single and over age 23, you are required to file a tax return if you have taxable income of more than $12,950, or self-employment income of more than $400.  Taxable income includes wages, but also taxable disability payments**, pensions, gambling prizes, unemployment compensation, investment income, and most other forms of income.  (**Some workplace injury payments may be non-taxable, depending on how the insurance plan is set up.) 

If you are married, or under age 24, the rules are more complicated.

If you don't have taxable income over the filing requirement, you aren't required to file, but you may qualify for certain benefits if you do file.
