The IRS is sending out a couple letters that are important for taxpayers to have ready for filling the 1040s.
> Letter 6419 is the "2021 Total Advance Child Tax Credit Payments" letter used to reconcile advance child tax credit payments.
> Letter 6475 is the "Your 2021 Economic Impact Payment" letter to determine eligibility to claim the recovery rebate credit #3.
Based on what we saw with the 2020 taxes, if you don't get these 100% correct, plan on lots of hours on the phone with the IRS and many months waiting on your refund.
