n-400 filling taxes?

[americanboy720]

For my previous 5 years, I did not worked for 1 year so I did not filed tax for that year. But I did filed tax for other 4 years.

Referring to below question in n-400
Since becoming a lawful permanent resident, have you ever failed to file a required Federal, State, or local tax return?

Does this means I failed to file a tax return?

I am not an immigration lawyer but if you did not file taxes because you didn't make enough money you didn't fail anything. You simply didn't file as per IRS rules. Should not be a problem.
