If you welcomed a baby in 2020 and haven't received stimulus payments for your new child, you may qualify for another $1,100 in stimulus cash.

NASDAQ reports both rounds of stimulus payments are an advance on a 2020 tax credit. To determine eligibility, the IRS had to use 2019 tax returns.

Because it's a 2020 tax credit, children born before Dec. 31, 2020, will qualify for both payments: $500 from the first round and $600 from the second round. 

To get your extra $1,100 of stimulus money, you'll need to file a tax return and get it as a refund recovery credit. The same rules apply if you adopted a child in 2020.

Eligibility for stimulus checks is largely based on income. Individuals earning less than $75,000 a year will receive the full $600. Heads of household earning less than $112,500 and married couples filing jointly earning less than $150,000 are also due the full amount. They will receive $600 per child under the age of 17, which is $100 more than in the first round.

 

The payments start phasing out for people making more money, at a rate of $5 per $100 of additional income. Some people who received the first payment may be phased out of the second round because the payments are smaller.

They will phase out entirely at $87,000 for single filers without children and $174,000 for those married filing jointly without children, according to an analysis by the Tax Foundation.
