My husband and I are married filing joint. He made around $35 this year, we have 1 child who is four. I only made $350 should I claim that? We are married filing joint. Will it raise or lower our refund? Maybe not effect it at all? Our refund amount right now is $3,900 (rounded). Thanks to anyone who can help! :)

If you made $350, you SHOULD claim it. It will have some effect on your return, but it will be negligible.

If it is 1099 income or undocumented, just put it on Line #21 as "other income", because it is below the threshold for self-employment taxes and thus does NOT require you submit a Schedule c por C-EZ.
