When the IRS asks you to prove a Child Tax Credit or Credit for Other Dependents claim, you respond with a clean, complete packet organized by identity, relationship, residency, and support.
Before we go deeper, here is one essential clarification that trips up even experienced pros. Form 14815‑A is the IRS checklist used for tax year 2021. For 2018–2020 and 2022–2025, the IRS uses Form 14815, not 14815‑A. If your notice references 2021, expect 14815‑A. If it references a different year in that 2018–2025 window, it will generally be 14815. The IRS confirms this in the Internal Revenue Manual and on its forms index.
Key takeaways
- Use the right checklist by tax year, 2018–2020 and 2022–2025 use Form 14815, tax year 2021 uses Form 14815‑A.
- Only submit when the IRS asks, follow the letter’s submission method and deadline.
- Prove four elements for each dependent, identity, relationship, residency, and support, organized and clearly labeled.
- Send clear copies, keep originals unless the IRS explicitly asks for them, and keep records for at least three years.
- Eligibility rules still hinge on Section 24 and Schedule 8812, age, relationship, residency, SSN, and income limits, so make sure your documentation matches those tests.
What Form 14815‑A is, and when you actually use it
- What it is, Form 14815‑A is a two‑page IRS checklist that tells you, and the examiner, exactly which documents to include when the IRS questions your 2021 Child Tax Credit, Additional Child Tax Credit, or Credit for Other Dependents. It is not a tax return, it is a documentation organizer. The IRS lists Form 14815‑A as revised June 2021.
- When you use it, only when the IRS asks, and only for 2021 cases. For other years in 2018–2025, the IRS references Form 14815, the same concept and structure, just not the 2021‑specific version. The Internal Revenue Manual spells out which year uses which form.
Why a checklist matters
Checklists speed up reviews. In our experience, packets that mirror the IRS’s elements, identity, relationship, residency, support, move through faster than mixed stacks of papers. The IRS’s due diligence materials for preparers point to using these supporting‑document checklists and to keeping copies on file for three years, a good rule for taxpayers too.
Quick year‑by‑year guide, which form do you send
| Tax year questioned | Checklist the IRS uses | Where this comes from |
| 2018 | Form 14815 | IRS Internal Revenue Manual 4.19.15 and forms index pages. |
| 2019 | Form 14815 | Same rule as above. |
| 2020 | Form 14815 | Same rule as above. |
| 2021 | Form 14815‑A | Special 2021 checklist, revised June 2021. |
| 2022 | Form 14815 | Back to 14815. |
| 2023 | Form 14815 | Same. |
| 2024 | Form 14815 | Same. |
| 2025 | Form 14815 | Current guidance points to 14815 for 2025 cases. ( |
Bottom line, match the checklist to the tax year in your notice. If your letter encloses a specific form, use that one.
Eligibility refresher, get the tests right before you send
Even a perfect packet will not help if the dependent does not meet the rules. For the Child Tax Credit, the child must be under 17 at year end, be your dependent, meet the relationship and residency tests, and have a valid SSN issued by the due date of the return. If the person is not a qualifying child, they might still qualify for the Credit for Other Dependents, which is nonrefundable and has its own tests. The current Schedule 8812 instructions walk through these checkpoints and phaseouts.
What the IRS really wants to see
- Identity and SSN, names and numbers that match IRS records.
- Relationship, birth or adoption papers, or court documents that tie you legally to the child.
- Residency, dated school, medical, or insurance records that place the child at your address for over half the year.
- Support, proof that you provided more than half of the person’s total support for the year, if your situation requires it.
At Accountably, we organize packets in four short sections that mirror those bullets. Reviewers think that way, and your response will feel complete and easy to clear.
Documents to gather, build a packet that passes on first read
Think of your response as four labeled folders inside one envelope. The IRS is not judging style, it is judging clarity and sufficiency.
Identity and SSN
- Social Security card or SSA printout for the dependent, clear copy.
- For you, list your TIN exactly as it appears on the return.
- Make sure names and numbers match the tax return and each proof you attach. Small mismatches create big delays. The IRS’s due diligence materials emphasize matching and retention.
Relationship
- Birth certificate showing your name, plus the child’s full name and date of birth.
- Adoption decree, guardianship, or foster placement agreement if applicable.
- If names changed, include the court order or multiple documents that connect the dots.
Residency
- School or daycare letters, enrollment forms, or report cards showing the child at your address and the dates.
- Medical or insurance records, explanations of benefits, or provider letters with dates and contact details.
- Lease, mortgage, or utility statements that tie the address to you, paired with school or medical records that include the child.
- The IRS’s CP75 topic explains how these notices work and points you to the detailed dependency document list.
Support
- Rent, utilities, food, clothing, education, medical, and childcare costs you paid, with dates and amounts.
- Bank statements, canceled checks, payroll deductions, or award letters that tie the payment to the expense.
- If multiple people contributed support, include a simple worksheet and, if requested, a signed statement clarifying who paid what.
Pro tip, label each page at the top left with the element, the dependent’s name, and a short note, example, Residency, Jordan Smith, ABC Elementary report card, Aug–Dec 2024.
How to access, complete, and submit the form safely
- Download the enclosed form from your notice or pull the current IRS version for your year, 14815‑A for 2021, 14815 for 2018–2020 and 2022–2025.
- Open it in a reliable PDF viewer, enter the requested information, and build a single PDF or packet with your labeled proofs.
- Follow the submission method printed on your letter. IRS correspondence typically allows secure online upload, fax, or mail, the method is set by the unit that sent your letter, so do exactly what the letter says.
- Send clear copies, not originals, unless the IRS explicitly requests originals. Keep your originals in a safe place. The IRS directs preparers to retain documents for three years, a good practice for taxpayers as well.
Can you sign electronically
The IRS now allows images of signatures and certain digital signatures for many compliance interactions when you are responding to an IRS solicitation, for example, a campus exam notice. If your letter tells you to sign or certify something, an electronic signature may be acceptable under the current IRS e‑signature policy, but always follow the exact instructions in your notice.
Deadlines, and what to do if you need more time
Your notice sets the deadline. Many responses are due in 30 to 60 days, but the date on your letter controls. If you cannot gather everything by then, contact the number on the letter and request more time. If you must mail, use a trackable method and keep the receipt. The CP75 topic explains what the IRS looks for with dependent documentation requests, which can help you prioritize.
Make the examiner’s life easy, a simple structure that works
- Start with a one‑page cover sheet listing each dependent in question, the element, and the page range in your packet.
- Add the completed IRS checklist, 14815‑A for 2021 or 14815 for other years in the 2018–2025 window.
- Group documents by element, not by source, for example, all residency proofs together, rather than mixing school and medical papers across the packet.
- Number pages and include a short index. It sounds formal, but it saves exam time and cuts follow‑up questions.
Friendly reminder, the CTC age test is strict. Under 17 at year‑end means a child who turned 17 on December 30 does not qualify for the CTC that year, though the ODC might apply. The 2024 Schedule 8812 instructions include this example directly.
Frequently asked questions
Is Form 14815‑A the right form for every year between 2018 and 2025
No. Form 14815‑A is the 2021‑specific checklist. For 2018–2020 and 2022–2025, the IRS uses Form 14815. Your notice will usually include the correct checklist, and the Internal Revenue Manual confirms the year‑by‑year mapping.
What documents carry the most weight for residency
School records and medical or insurance records with dates and your address tend to be strong because they are third‑party and time‑stamped. Pair them with lease or utility statements in your name to create a clear timeline. The IRS’s CP75 topic points you to the dependency document list so you can choose the best items you have.
Do I send originals
No, send clear copies unless your notice specifically asks for originals. Keep originals safe. Preparers are told to keep copies for three years, and that retention approach works for taxpayers too.
Can I e‑sign anything in my packet
In many compliance interactions where you are responding to an IRS request, the IRS accepts images of signatures and digital signatures, subject to its e‑signature policy. If your notice includes a signature requirement, you can usually satisfy it electronically, but follow the exact instructions and use the submission channels the IRS provides.
Where do the eligibility rules live today
Eligibility for the Child Tax Credit and the Credit for Other Dependents is set under Section 24 and explained each year in the Schedule 8812 instructions. For 2024 returns, the IRS refreshed those instructions in late 2024, and the same structure applies, age, relationship, residency, SSN rules, and phaseouts.
My notice references Form 8867. Is that related
Yes, but it serves a different purpose. Form 8867 is the paid preparer due diligence checklist that must accompany certain returns that claim the CTC or ODC. It is about preparer obligations, not your substantiation packet. That said, the IRS’s 8867 page links to the very supporting‑document checklists we are discussing, including Form 14815 and 14824.
Common mistakes that slow reviews
- Mixing documents by source instead of by element, the examiner has to hunt through pages.
- Names that do not match across the return, the Social Security card, and the school letter. Fix typos before you send.
- Missing dates on residency proofs, undated letters are weak.
- Sending only financial statements for support without tying them to specific expenses. Add a simple worksheet that totals rent, utilities, food, and childcare.
- Using the wrong checklist for the tax year, if the year is 2021 use 14815‑A, not 14815.
Simple worksheet idea you can copy
Create a one‑page support summary per dependent with these rows, rent or mortgage, utilities, food, clothing, education, medical, childcare, transportation. Add columns for month, amount, payee, and proof page number. This keeps everything traceable, and it matches how reviewers think about the support test.
Quality control checklist before you hit send
- Each dependent has identity, relationship, residency, and support proof.
- Every document is readable, dated, and shows the right names and addresses.
- The form number matches the tax year, 14815‑A for 2021, 14815 for other years in 2018–2025.
- The packet includes a short index and page numbers.
- You followed the submission method and deadline on the letter. If electronic upload is offered, use it.
Where Accountably fits, only when helpful
If you run a firm, you know these notices spike right when production peaks. Our U.S.‑led offshore delivery teams are trained on standardized workpapers and IRS documentation logic, so your packet gets assembled the same way every time, inside your systems, and labeled for fast review. That structure protects partner time while keeping quality tight and deadlines predictable. We mention this only because it mirrors the exact discipline a good 14815 or 14815‑A response requires.
Step‑by‑step, build and send a clean packet in one sitting
- Read the letter twice
- Circle the tax year, the due date, the submission method, and the form number named in the notice. If the letter encloses a checklist, use that checklist.
- Create your index and folders
- Make four sections, Identity and SSN, Relationship, Residency, Support. List the page range you expect for each.
- Pull proofs and label them
- Write the element, dependent’s name, and a short description at the top of each page. Fix any name or date mismatches now.
- Complete the IRS checklist
- Fill out Form 14815‑A for 2021 cases, or Form 14815 for 2018–2020 and 2022–2025. Place it at the front of the packet.
- Combine, review, and sign if required
- Combine everything into a single PDF if your notice allows uploads, or assemble a neat paper packet. If a signature is required, the IRS may accept an image or digital signature in this kind of compliance interaction, but follow your letter.
- Submit exactly as instructed
- Use the upload link, fax number, or address in your letter. Keep the confirmation page, fax report, or a certified mail receipt.
- Keep a full copy
- Retain the final packet and any confirmations for at least three years. Preparer guidance stresses retention, and that discipline helps if the IRS follows up.
One last eligibility check, then exhale
If you claim the Child Tax Credit, confirm the child was under 17 at year end and had a valid SSN by the return’s due date. If the person is older or does not meet the CTC tests, check whether the Credit for Other Dependents applies instead. The IRS’s current Schedule 8812 instructions remain your north star for the specifics.
Wrap‑up
You do not need to impress the IRS with volume, you need to answer its questions clearly. Use the right form for the year, 14815‑A for 2021 and 14815 for 2018–2020 and 2022–2025, label your packet by element, and send crisp copies by the method on your letter. That is how you reduce back‑and‑forth, protect your refund, and keep your season moving.
If a notice lands during your busiest week, do not panic. Block ninety minutes, follow the steps above, and ship a packet that an examiner can clear without a second call.
