Your application could be denied if USCIS finds that you willfully failed to pay taxes or committed tax fraud.

Yes, unpaid taxes can be a problem USCIS checks your financial responsibility, and owing taxes may reflect poorly on your moral character.

Filing late or not filing at all is seen more negatively than simply owing money file on time even if you can’t pay everything.

You can still apply if you owe taxes, as long as you disclose it honestly and show you’re making good-faith efforts to pay.
