SSN for Newborn: How to Apply & Claim Child Tax Credit Safely (2025)
One of the first administrative steps after a baby is born in the U.S. is applying for a Social Security Number (SSN).
Parents often ask: “Is it automatic?”, “What if the card hasn’t arrived yet?”, or “Can we still claim the Child Tax Credit without an SSN?”
As of 2025, delayed SSN issuance remains one of the most common causes of tax filing errors and refund delays.
1️⃣ Why a Newborn SSN Matters for Taxes
An SSN is essential to treat a child as a tax dependent under U.S. federal tax law.
Major benefits such as the Child Tax Credit (CTC) and Additional Child Tax Credit (ACTC) require a valid SSN issued before the tax return is filed.
Even if the child is a U.S. citizen by birth, no SSN means no child-related tax credits for that filing year.
2️⃣ How to Apply: Hospital vs SSA Office
Most parents apply for their baby’s SSN directly at the hospital when completing the birth certificate paperwork.
The information is transmitted to the Social Security Administration using Form SS-5.
- Hospital application: Birth registration → state records → SSA processing
- Direct application: In-person visit or mail submission to a local SSA office
Processing may be delayed if there are name spelling errors, mismatched parent information, or incomplete records.
3️⃣ Processing Time & What to Do If It’s Delayed
In 2025, newborn SSN cards typically arrive within 2–4 weeks after birth.
During peak periods (late year and tax season), delays of 6 weeks or longer are not uncommon.
A delayed card does not automatically mean an error.
However, if more than six weeks pass with no update, parents should contact the SSA before filing taxes.
4️⃣ Key Tax Rules in the Baby’s Birth Year
- A baby born on December 31 still qualifies for the full Child Tax Credit
- No SSN = no dependent or child tax credits
- If the SSN is delayed, consider Form 4868 (filing extension)
- Only one working parent is sufficient to claim the child as a dependent
Filing without the SSN and “fixing it later” often leads to amended returns and refund delays, which can usually be avoided with a short extension.
5️⃣ EA Practical Example
A child is born on December 28, 2025, but the SSN card arrives in February 2026.
→ The child is fully eligible as a dependent for the 2025 tax year.
→ The safest approach is to file an extension and submit the return after receiving the SSN.
