2026 Child Tax Credit Amount After the OBBB Permanence
The Child Tax Credit rises to $2,200 per qualifying child under 17 for 2026 under the One Big Beautiful Bill Act (2025), with the refundable portion (Additional Child Tax Credit) capped at $1,700 per child indexed for inflation per the IRS Child Tax Credit page. The OBBB also made the credit permanent — it no longer reverts to $1,000/child at the end of 2025 as previously scheduled. Phase-out remains at $400,000 modified AGI (MFJ) or $200,000 (single/HoH), reducing the credit $50 for every $1,000 above the threshold. A family with two kids earning $50,000 gets the full $4,400; at $250,000 single AGI the $4,400 credit phases down to $1,900. To claim the refundable portion (up to $1,700/child), you need $2,500+ in earned income. Updated 2026-07-06.

Frequently Asked Questions
How much is the child tax credit in 2026?
The maximum credit is $2,200 per qualifying child under age 17. This was increased from $2,000 by the One Big Beautiful Bill Act and is now indexed for inflation.
What is the refundable portion?
Up to $1,700 per child is refundable as the Additional Child Tax Credit (ACTC). This means you can receive up to $1,700 per child as a refund even if you owe no income tax, calculated as 15% of earned income over $2,500.
When does the credit phase out?
The credit begins to phase out at $200,000 MAGI for single, head of household, and married filing separately filers, and $400,000 for married filing jointly. It reduces by $50 for every $1,000 over the threshold.
What age does my child need to be?
Your child must be under 17 years old at the end of the tax year (December 31, 2026 for the 2026 tax year).
Does my child need a Social Security number?
Yes. Each qualifying child must have a valid Social Security number (SSN) issued before the due date of your tax return. An ITIN is not sufficient for the child tax credit.
Can I get the Child Tax Credit if I owe no federal tax?
Partially — the refundable portion (Additional Child Tax Credit) pays up to $1,700 per child in 2026 even if your income tax liability is zero. To qualify for the refundable portion you need at least $2,500 in earned income; the refundable amount is 15% of earned income above $2,500, up to the $1,700-per-child cap. Passive income (Social Security, investment income, unemployment) does not count as earned income for this test.
Is the $2,200 Child Tax Credit permanent or temporary?
Permanent, thanks to the One Big Beautiful Bill Act (OBBB) signed in 2025. Before OBBB, the credit was scheduled to drop back to $1,000/child at the end of 2025. OBBB set the credit at $2,200 starting 2026, indexed for inflation, with no sunset date. The refundable ACTC portion also stays at $1,700, indexed. Congress can always change the rules but no reversion is currently scheduled.
