What the IRS page says the letter is
The page says the IRS began issuing Letter 6475, Economic Impact Payment (EIP) 3 End of Year, in January 2022. It helps EIP recipients determine whether they’re eligible to claim the Recovery Rebate Credit on their 2021 returns by giving the total of the third payment and any plus-up payments received for tax year 2021. For married individuals filing a joint return, each spouse receives their own letter showing half of the total.
What it covers and what it doesn’t
The page says Letter 6475 applies only to the third round of EIP issued between March 2021 and December 2021, including plus-up payments. Plus-up payments were additional EIP 3 payments for people who received a third payment based on a 2019 return or on Social Security Administration, Railroad Retirement Board or Veterans Administration information, and were eligible for an additional amount based on their 2020 return.
What the IRS page says about the Recovery Rebate Credit
Most eligible people already received the full amount, the page says. Anyone who didn’t should review the payment information to determine whether to claim the Recovery Rebate Credit for tax year 2021. Its example: parents of a child born in 2021, or who added a new qualifying dependent in 2021, did not receive a third-round payment for that dependent and may be eligible to receive up to $1,400 for the dependent by claiming the credit.
Where to check the amounts
Online Account includes summaries for the third Economic Impact total payment and the advance Child Tax Credit total. For a joint return, each spouse logs into their own Online Account for their portion. The page gives no response date, form or mailing address.
