The Child Tax Credit amount in 2026 depends on whether Congress extends the current law or lets it expire

The Child Tax Credit for 2026 is not yet set in stone. Right now, the credit is worth up to $2,000 per child under age 17. But that amount is scheduled to drop to $1,000 per child on January 1, 2026, unless Congress passes a new law to extend the higher amount. Whether you get $2,000 or $1,000 per child will depend entirely on what lawmakers decide in 2025.

This is not a guess or a proposal — it is what the current tax law says will happen automatically. The $2,000 credit was set to expire at the end of 2025 as part of a 2017 tax law. If Congress does nothing, the credit shrinks to $1,000 on January 1, 2026. If Congress votes to extend it, the $2,000 amount could stay in place for one year, several years, or permanently.

Key Takeaways

  • The Child Tax Credit is currently $2,000 per child under 17, but this amount is set to drop to $1,000 per child starting January 1, 2026, unless Congress extends it.
  • Congress will decide in 2025 whether to keep the $2,000 amount, and that decision will not be final until late in the year.
  • The credit phases out at higher income levels, so your actual credit may be less than $2,000 or $1,000 depending on your household income.
  • Some families receive the credit as a refund if they owe no tax, but the refundable portion is also set to change in 2026 unless extended.

How the credit works and who receives it

The Child Tax Credit reduces the amount of federal income tax you owe, dollar for dollar. If you owe $3,000 in tax and you have two children under 17, you subtract $4,000 (two children × $2,000) from what you owe. In this case, you would owe zero tax and receive a refund of $1,000.

You must claim the child on your tax return and meet income limits. For 2025, the credit begins to shrink if your income exceeds $400,000 (married filing jointly) or $200,000 (single or head of household). The exact thresholds for 2026 will be adjusted for inflation, so they will be slightly higher. The child must be a U.S. citizen, national, or resident alien, and you must have a valid Social Security number for them.

The difference between $2,000 and $1,000 per child

A family with three children under 17 would see a difference of $3,000 per year if the credit drops from $2,000 to $1,000 per child. That is $1,000 × 3 children. For a family with one child, the difference is $1,000 per year. This affects your tax bill when you file your 2026 return in early 2027.

The refundable portion of the credit — the part you can receive as a refund even if you owe no tax — is also set to change. Currently, up to $1,600 per child can be refunded to you. In 2026, that refundable amount is scheduled to drop to $1,000 per child unless Congress extends the higher amount. This matters most to lower-income families who owe little or no tax.

When Congress will decide on the 2026 credit

Congress typically makes decisions about tax credits and deductions in the fall of the year before they take effect. For the 2026 credit, lawmakers will likely debate and vote on an extension sometime in late 2025. This means you will not know the final amount until closer to the end of the year.

Tax law changes can happen quickly or slowly depending on the political situation. Some extensions pass with broad support; others are debated for months. If you are planning your finances around the Child Tax Credit, plan for the $1,000 amount and treat any higher credit as a bonus if Congress extends it.

How inflation adjustments affect the income limits

The income thresholds where the credit begins to phase out are adjusted each year for inflation. In 2025, the credit starts to shrink at $400,000 (married filing jointly). In 2026, that threshold will be higher — probably around $410,000 or $415,000, depending on inflation that year. The IRS announces the exact number in late 2025.

If your income is close to the phase-out threshold, the inflation adjustment could mean you receive a slightly larger credit in 2026 than you would have in 2025, even if the per-child amount drops from $2,000 to $1,000. The phase-out rate is $50 for every $1,000 (or fraction thereof) over the threshold, so a higher threshold means a smaller reduction for high-income families.

What to do now if you have young children

If you have children under 17, make sure your tax records are current and you have valid Social Security numbers for each child. When you file your 2025 tax return in early 2026, you will claim the $2,000 credit (or whatever amount applies to 2025). That return is separate from your 2026 return, which you will file in early 2027 and which will use whatever credit amount Congress has set for 2026.

Keep an eye on tax news in the fall of 2025 if you want to know the 2026 amount before you file your 2025 return. The IRS website and major news outlets will report any changes Congress makes. You do not need to take action now — just be aware that the amount may change.

Frequently Asked Questions

Will the $2,000 Child Tax Credit definitely drop to $1,000 in 2026?

It will drop unless Congress votes to extend it. The current law says it expires at the end of 2025. Congress could extend it for one year, multiple years, or permanently, but if they do nothing, the credit automatically becomes $1,000 per child on January 1, 2026.

Does the credit explore to children over 17?

The $2,000 credit applies only to children under 17. There is a separate $500 credit for other dependents, including children 17 and older, but that credit is not scheduled to change in 2026.

What if my income is too high for the credit?

The credit phases out at $400,000 (married filing jointly) and $200,000 (single). If your income exceeds these amounts, you lose $50 of the credit for every $1,000 over the limit. At very high incomes, the credit may be zero. The exact thresholds for 2026 will be higher due to inflation.

Can I claim the credit if the child does not live with me full-time?

The child must live with you for more than half the year. If you share custody, only the parent who meets this requirement can claim the credit. You will need the child's Social Security number and must be able to prove the residency requirement.

When will I know for sure what the 2026 credit amount is?

Congress will likely vote on an extension in the fall of 2025. The IRS will announce the final amount and any inflation adjustments in late 2025, before you file your 2026 return in early 2027.
