Community property does not just mean real property. Money that you earn while married is also community property. Half of your W-2 wage (or other income) belongs to your spouse. In a community property state, you enter 1/2 of your W-2 income on your tax return and 1/2 on your spouses. If were only married for a month, then that would only apply the the income earned doing that period.
Dealing with community property laws is one very good reason to file jointly which avoids income allocation altogether.
