When is it illegal to file for unemployment benefits?

It is illegal to file for unemployment benefits if you are not unemployed through no fault of your own, such as quitting a job voluntarily or being fired for misconduct. Additionally, providing false information or failing to report income while receiving benefits is also illegal. Claiming benefits while working or having other sources of income that you do not disclose can lead to penalties. Always adhere to your state's specific guidelines and requirements when filing for unemployment.
