Child Tax Credit 2027: The First Inflation Increase Is Coming — What Families Should Know
-- reading | Updated:
The $2,200 per-child credit just became permanent — and a little-known clause means 2027 is the first year its amount can legally grow with inflation. One rule, though, could erase it for half a million families.

The Child Tax Credit pays $2,200 per qualifying child under 17 on returns filed in 2027 (tax year 2026), with up to $1,700 per child refundable through the ACTC. Starting with tax year 2027 — the return you'll file in early 2028 — the credit's amount indexes to inflation for the first time, meaning the IRS can raise it above $2,200 when it publishes annual adjustments in late 2026 or late 2027.
When Congress passed the One Big Beautiful Bill Act in July 2025, most headlines stopped at "$2,200 made permanent." The part that matters for next year is buried deeper: the law ties the credit to inflation starting with tax year 2027. That makes the CTC the rare tax benefit that can quietly get bigger without any new vote in Washington.
The Numbers Families Get Right Now
| Rule | Amount / detail |
|---|---|
| Maximum credit | $2,200 per child under 17 (permanent) |
| Refundable portion (ACTC) | Up to $1,700 per child; 15% of earned income over $2,500 |
| Phaseout starts | $200,000 single · $400,000 married filing jointly (-$50 per $1,000 over) |
| SSN requirement | Work-eligible SSN needed for child AND at least one parent; ITIN doesn't qualify |
| How you claim it | Form 1040 + Schedule 8812, filed once a year — no monthly payments |
The Inflation Clause Nobody Noticed
Before the 2025 law, the credit was set to crash back to $1,000 in 2026. The law cancelled that cliff — and added annual inflation indexing from 2027 onward. In practice, the IRS rounds adjustments in steps, so if inflation runs moderate, the first bump may be small or even zero; the official figure arrives each fall in the IRS's annual revenue procedure. Either way, $2,200 is now the floor, not a ceiling that expires.
The Rule That Disqualifies Half a Million Kids
The same law hardened the Social Security number requirement: at least one parent on the return must hold a work-eligible SSN, and so must the child. Mixed-status households where parents file with ITINs generally cannot claim the credit anymore — the Tax Policy Center estimates around 500,000 children lose eligibility as a result. If your situation changed recently, verify every SSN matches SSA records before filing; name mismatches are the top cause of held refunds.
What It Means for You
You claim the credit once a year on your return — there are no monthly checks despite viral posts claiming otherwise. Remember the refund timing trap: any return claiming the ACTC or EITC is held until mid-February by federal law, so early filers see that money around the start of March. And if your income hovers near the phaseout line, extra 401(k) or HSA contributions can pull you back under — each $1,000 of AGI reduction inside the zone is worth $50 of credit.
