Letter 6419 and Letter 6475 are not bills and not warnings. They are statements of money the IRS sent you in 2021, and they exist so you can reconcile that money on your 2021 return. They still surface in notice searches because mismatched 2021 amounts continue to generate IRS correspondence, amended returns and account questions.
Letter 6419: advance Child Tax Credit
For 2021, the IRS paid part of the Child Tax Credit in advance. Letter 6419 tells you how much you received in those payments and how many qualifying children the IRS used. The IRS says to keep the letter with your tax records, compare the advance payments with the credit you could claim for 2021, and file a 2021 return. You can check the figures with the IRS Online Account.
If you were eligible but did not receive advance payments, the IRS explained that you could claim the full credit on your 2021 return, even if you did not normally file.
Letter 6475: third Economic Impact Payment
Letter 6475 shows the total third-round Economic Impact Payment you received, including plus-up payments, and helps you decide whether you could claim the Recovery Rebate Credit on your 2021 return. For married couples who filed jointly, each spouse gets a letter showing half of the total. The IRS used an example of parents of a child born in 2021 who might claim up to $1,400 for that dependent. Your Online Account summarizes your third EIP total and your advance Child Tax Credit total.
Reading the letters
| Letter | What it shows | Where to compare |
|---|---|---|
| 6419 | Total advance Child Tax Credit payments and the number of children used | The Child Tax Credit figures on your 2021 return |
| 6475 | Total third Economic Impact Payment, including plus-ups | The Recovery Rebate Credit figure on your 2021 return |
The totals matter because a 2021 return that does not agree with the IRS's payment records can trigger a correction notice or an examination of the credit.
What to do now
- Keep the letters with your 2021 records. They are evidence if the IRS later questions your 2021 return or credits.
- If you have a notice about 2021 amounts, compare it with these letters and with your transcripts. See tax transcripts.
- If you did not file for 2021, act promptly. The IRS notes that refund claims have strict time limits. Under the general rule described in IRS materials, a return must be filed within three years of the due date to claim a refund. That window has generally closed for 2021 by now, so a professional should confirm your situation. See statute of limitations.
- If you filed and the amounts differ, an amended return may be appropriate. See amended returns.
- Do not rely on the letters for current-year filings. The IRS says they relate only to 2021.
Common mistakes
- Throwing the letters away after filing. They are your only summary of what you received.
- Entering the wrong total from the letter. Use the letter or your account, not memory.
- Assuming a joint filer's letter shows the full household amount. Each spouse's letter shows half the EIP total.
- Treating an old letter as proof of eligibility for a current credit. Eligibility is determined year by year.
- Ignoring a later correction notice about 2021 because the letters seemed routine.
Interest and penalties
The letters themselves carry no penalty or interest. If your 2021 return or an IRS correction results in a balance, other notices will explain it. See CP14 and CP11.
When to involve a CPA
Talk to a CPA if your 2021 credits were reduced, if you received a notice that does not match the letters, or if you are unsure whether a 2021 amended return is still possible. We can reconstruct the year from your transcripts and the letters and, with a signed Form 2848, contact the IRS for you.
