Business & farm

This is my thinking I live in calif.

If I fill it out 1/2 and half everything 

Will it cause them to give refund my husband less maybe instead of more

But I also read somewhere if u don't claim at least one exemption (non injured spouse it will be rejected.

I don't know why this seems so difficult I just don't want to have to send it in and get rejected from my own mistake.

So in California I should claim half of everything between us both. That's listed as income and credits and ftwh (fed inc.tx.whld)
