Form 4547 is the IRS form parents file to open a Section 530A account and unlock the $1,000 government deposit for an eligible child. It's short, it's free, and for most families it takes about 10 minutes. This walkthrough covers every section, every common mistake, and what happens after you mail it.
Prefer to skip the manual paperwork? The guided Form 4547 Filler asks the same questions in a form-by-form wizard and prints a PDF with the correct IRS mailing address for your state.
Before You Start
Gather these in one sitting so you aren't hunting for numbers mid-form:
- Your child's Social Security number. Required. ITIN works only in narrow cases (see Eligibility Guide).
- Your child's date of birth. Must be between Jan 1, 2025 and Dec 31, 2028.
- Your child's full legal name. Exactly as it appears on their Social Security card — middle names, hyphens, apostrophes included.
- Your SSN and full legal name. The parent or legal guardian filing the form.
- Your mailing address. Where the IRS confirmation letter will land.
- Your filing status. Single, married filing jointly, married filing separately, head of household, etc.
If you're filing along with your federal return (recommended), also have a copy of that return handy — a few fields must match.
Section-by-Section Walkthrough
Section 1 — Child's information
The IRS compares the child's name, SSN, and date of birth to their Social Security Administration records. Any mismatch kicks the form back.
- Name: Match the Social Security card exactly. If the card reads "Elena Marie García-López," do not write "Elena M. Garcia Lopez."
- SSN: Use the child's SSN, not yours. This is the #1 most common filing error.
- Date of birth: In MM/DD/YYYY format.
Section 2 — Filer's information
This is the parent or legal guardian filing the form. You must be able to claim the child as a dependent on a U.S. federal tax return.
- Name and SSN: Yours, not the other parent's unless you're the primary filer.
- Address: Your current residential address. A P.O. box is accepted but only if it matches your IRS-on-file address.
- Filing status: Must match the status on your most recent federal return. If you're filing 4547 alongside your return, match whatever you're filing for the year.
Section 3 — The 530A Election
This is the single most important box on the form. Checking it is what legally triggers the $1,000 deposit. It reads something like:
I hereby elect to establish a Section 530A account for the child named above and to receive the Section 530A contribution authorized by 26 U.S.C. §530A.
You check the box. That's the election. No narrative, no signature here — that comes in Section 4.
Section 4 — Signature
You sign and date. If you're filing electronically with your federal return, your e-signature covers this. If filing by paper, sign in blue or black pen only — the IRS rejects pencil and unusual ink colors.
Multi-child filings
If you have more than one eligible child, you can list up to four dependents on a single Form 4547. Each child's Section 1 repeats for each dependent. You sign once at the bottom.
How to Submit
You have two paths. The first is meaningfully faster.
Option A — File with your federal tax return (recommended)
Attach Form 4547 to your federal income tax return (Form 1040). File electronically if possible — e-filed 4547s are typically processed within 2–4 weeks, versus 4–6 weeks for paper mail.
Most tax software supports Form 4547 as an attached schedule. Some older versions don't — if your software can't attach 4547, mail it separately using Option B.
Option B — Mail separately
Send the signed form to the IRS processing center that services your state. The addresses are state-specific; the wrong address slows processing by weeks. The Form 4547 Filler prints the right address on the cover sheet based on your state.
- Use a certified-mail or trackable shipping option
- Keep a copy of the signed form for your records
- Do not include payment; the form has no filing fee
What not to do
- Don't fax. The IRS does not accept Form 4547 by fax.
- Don't email or upload to a portal. There is no electronic-only submission path separate from your tax return.
- Don't staple payment. There is no fee; anything you include gets routed incorrectly.
After You File
Weeks 1–4 — Processing
The IRS confirms eligibility, matches the child's SSN to the SSA database, and forwards the approved filing to the Treasury. You won't hear anything during this window. This is normal.
Weeks 4–6 — Account opens and deposit lands
Robinhood opens the Section 530A custodial account in your child's name and the Treasury deposits $1,000. You receive two separate letters:
- From the IRS, confirming the 530A election was accepted.
- From Robinhood, with the account number and login instructions.
The $1,000 is automatically invested in the default S&P 500 index fund (~0.03% expense ratio). You can change the fund or roll over to a different brokerage once the account is open — see How to Roll Over Your Account.
If something goes wrong
- Rejection letter. The most common cause is an SSN/name mismatch. Fix the error and refile — you don't lose your filing slot.
- No letter after 8 weeks. Call the IRS Section 530A processing line (on the Robinhood confirmation page). Have your child's SSN ready.
- Wrong deposit amount. Rare, but call the IRS, not Robinhood — deposits come from Treasury.
Common Filing Mistakes
We covered the top seven in a dedicated blog post, but the short list:
- Using the parent's SSN in Section 1 instead of the child's. Auto-rejection.
- Typo in the child's name. Even one character off from the SSA record fails.
- Date of birth in the wrong format. Use MM/DD/YYYY.
- Forgetting to check the 530A election box. Without it, the form is just background noise to the IRS.
- Signing in pencil. Blue or black pen.
- Filing with the wrong state's IRS processing center. Adds weeks.
- Assuming it filed because you filed your return. Some tax software skips optional attachments silently — verify the 4547 made it.
Amending or Correcting a Filing
If you notice an error after submitting Form 4547, you have two options depending on timing.
Before the IRS processes it (first 2–4 weeks)
Call the IRS Section 530A processing line and request a hold on the original filing. Resubmit a corrected Form 4547 marked "AMENDED" across the top. The IRS will process only the amended version.
After the IRS processes it
If the account has already opened at Robinhood, most corrections happen at the brokerage level — updating a misspelled name, correcting a wrong address. These go directly to Robinhood customer support, not the IRS.
Genuine eligibility errors (wrong child's SSN, for example) require closing the incorrectly-opened 530A and filing a new Form 4547 for the right child. This is rare and the IRS handles it individually.
Electronic Filing Details
Most major tax software (TurboTax, H&R Block, TaxAct) added Form 4547 support in their 2026 filing season releases. If your software version is from before January 2026, it may not include 4547 as an optional attachment. Check the forms list in the software or the vendor's release notes.
IRS Direct File (the free IRS-run e-filing service) added 4547 support starting in the 2026 filing season. For families who already use Direct File for their 1040, attaching a 4547 is a single additional step with pre-filled dependent information from the return.
Paper-filed 1040s can include paper Form 4547 as an attachment. The combination mails to the same IRS processing center as the 1040. This is the slowest path — expect 6–8 weeks.
Is There a Deadline?
You can file Form 4547 any time before your child turns 18. There's no hard calendar cutoff during the child's lifetime. But every year you wait is a year of compounding you don't get back. At 7% annual returns, delaying 5 years costs roughly $970 off the final balance from the $1,000 deposit alone. See What Happens If I Do Nothing? for the full math.
Filing alongside your April 15 tax return is the preferred path because it's the fastest to process. Missed April 15? You can still file later — see I Missed the April 15 Deadline.
Common Questions
How long does the whole process take end-to-end?
From mailing Form 4547 to $1,000 showing up in the child's account: typically 4–6 weeks for paper, 2–4 weeks for e-filed attachments.
Can both parents file?
Only one Form 4547 per child. Married filing jointly covers both parents in one filing. Separated or divorced parents should decide in advance who files, or the form gets rejected as a duplicate.
What if I'm not a U.S. citizen?
The child must be a U.S. citizen with a valid SSN. The filing parent can be a U.S. tax resident without being a citizen. See the Eligibility Guide for the full residency rules.
What if my tax software doesn't support Form 4547?
File 4547 separately by mail. Your tax return processes normally; 4547 takes its own path.
Do I need a lawyer or CPA?
No. Form 4547 is consumer-facing paperwork, not a complex tax election. A CPA is useful if you have unusual filing-status or dependency situations, but the form itself is deliberately simple.
The Bottom Line
Filing Form 4547 is the lowest-effort, highest-return move available for most parents of eligible kids. Ten minutes of paperwork equals $1,000 in the child's account plus 18 years of tax-free compounding.
