1)Taxpayer passed away in March 21 and had only earned $10,000 W-2, single no kids. I know he is eligible for full standard deduction. Is he also eligible for full EIC credit?

2)Another scenario. 30yr old kid lives with parents. Eared $12,000 on W2. Is he also eligible for EIC? (No Investment income, us citizen, parents can't claim due to age and income threshold). 

Both seem unlikely candidates, but rules seem to indicate they eligible. Is this correct?

Thank you
