Late in the tax season, the IRS agreed that in community property states, the income from UI was community income, therefore both spouses can claim the $10,200 exemption from income, even if only one received UI, provided they meet the other qualifications. It was iffy for a while if the IRS would agree, but eventually (like in late May) they did. So if your Married CA client had more than $20,400 in UI, and you only excluded $10,200, the IRS just corrected the return and gave your clients their refund.
