EITC and Unemployment Income
It was just brought to my attention that, even though UI is calculated into your AGI, the EITC is based only on earned income. Last year my only income was UI and my spouse made less than $10k in earned income. The year before, in 2020, I earned $4k outside of UI income. Is it possible and advantageous to include that in my 2021 return? I read somewhere if you made more in 2020, you could claim that income for this year. Also, does it complicate things if we weren't married in 2020? Not sure if it helps, but he earned no income that year.
If I can claim my 2020 income, how do I go about this? Thank you in advance.
