Is my brother eligible for a stimulus check is his income last year was the florida lottery winnings

[SweetieJean]

Is he a dependent?

eligibility is not impacted as long as your income is under $75,000 if filing single.

since he had winnings, he should file a tax return and the stimulus would show up on there. 

[Opus 17]

Any person is eligible for a stimulus payment or rebate as long as they can’t be claimed as a dependent by another taxpayer, and as long as they have a Social Security number valid for work (meaning they are a US citizen or a green card holder).

if your brother did not file a tax return last year and can’t be claimed as a dependent, the IRS might not have had his information to pay him around one or round two stimulus payment.  If he files a 2020 tax return to report his Florida lottery winnings, the tax return will automatically claim the recovery rebate also.

Filing a tax return will also allow the IRS to identify him to pay the round three $1400 stimulus payment.
