You have to provide documentation. I won't be able to do it until I file my 2022 tax return.
To prove your household income is at 200% or less of the Federal Poverty Guidelines, you must submit one or more of the following documents:
The prior year's state, federal, or Tribal tax return
Current income statement from an employer or paycheck stub
A Social Security statement of benefits
An Unemployment or Worker's Compensation statement of benefits
A Federal or Tribal notice letter of participation in General Assistance
A Divorce Decree, child support award, or other official document containing income information
Note: If the document doesn't cover a full year, such as a pay stub, you must show the same document for (3) months in a row within the same year to provide your gross annual income.
