How to claim stimulus money in your tax returns for new dependents in 2020 U.S. Treasury check (File) (Source: Hawaii News Now) By Chelsea Church | January 6, 2021 at 9:49 PM EST - Updated January 7 at 2:48 PM AUGUSTA COUNTY, Va. (WHSV) — If you had a baby or gained any new dependents under the age of 17 from January 1, 2020, to December 31, 2020, you may be eligible to get stimulus money you initially missed out on. Overall, it’s about $1,100 you could get back, but local tax experts explained it would be broken up between two tax returns. The $500 from the first round can be reconciled by filing your 2020 taxes, while the $600 from the most recent round would have to be filed in 2021 taxes.
