The IRS will send me money each month?

Starting in July, the IRS will send you 1/12th of what they expect your 2021 child tax credit to be (up to $3,600 per child). They are basing their calculations off of the income and children that you claimed on your 2020 return. When you file your 2021 tax return, you will then true up with the IRS and either pay them or they will pay you any difference. If you want to unenroll from the monthly payments then go to www.irs.gov/childtaxcredit2021
