Married filing separately in community property state - question

The rule for 2017, is for married filing separately, you only have to report taxes if you make over $4050.  Let’s say you are in a community property state, I think that means husband and wife split 50/50 of the income.  So let’s say husband makes $7000, does he still have to file taxes?  Does that mean he actually made $7000 or does it mean he technically made $3500 and doesn’t have to file taxes (and wife gets the other $3500)?
