Nonsense.
Fact: If you have no tax liability for any given year it is entirely legal not to file a return. You cannot be penalized or prosecuted for failing to file a return you were not required to file.
One might file a return for a year during which you had no taxable income because you had loss carry-forwards, or for many other reasons.
Typical FR tax and financial illiteracy. Do NOT seek tax advice on this site. Or any other.
The only ones who are not required to file are those whose taxable income is below a certain level.
If your income is above that level you are required to file whether you owe or not.
You are correct about one thing tho. Do not take your ideas from an internet discussion.
