I had a baby in 2020. Will I get the extra $500? Eventually. But you’ll have to wait until you file your taxes for 2020, which means you won’t get the $500 until early 2021. The stimulus checks are technically a credit for 2020 taxes. But since we’re only three months into the year, the IRS has to use our 2018 or 2019 returns to determine whether we’re eligible for payments. Since your new addition won’t be listed on those returns, you’ll have to wait another year for the $500 credit.
