OK. Strictly speaking, you have to file a ND tax return and there aren't any offsets for gambling losses. Your tax on $1200 would be $13
Here are the links to the ND non-resident tax return (very simple) and the tax tables. I can't tell you to not file, but I can tell you it would be much less expensive to fill out the form yourself and mail it to ND with a $13 check.
