Federal CTC Income Limits for 2026

The phaseout thresholds for the federal child tax credit haven’t changed from prior years under IRC §24. If you’re married filing jointly, the credit starts shrinking once your modified adjusted gross income passes $400,000. Single filers and heads of household hit the phaseout at $200,000.

For every $1,000 of income above those thresholds, you lose $50 of credit. A married couple earning $440,000 with two kids would lose $2,000 of their $4,000 total credit. Earn $480,000 and the credit disappears entirely.

One detail that trips people up: the phaseout applies to your modified AGI, not your taxable income. That means it’s calculated before standard or itemized deductions. Your gross income matters here, not the number after deductions.

New York’s Empire State Child Credit

This is where NYC families get an extra break that most other states don’t offer. New York’s Empire State Child Credit gives qualifying families the greater of 33% of the federal child tax credit or $100 per qualifying child.

The state credit has its own income limits, tied to New York AGI. For 2026, if your NY AGI exceeds $110,000, the Empire State credit begins to phase out. That’s a much lower threshold than the federal one, which catches a lot of NYC earners off guard. A household pulling in $150,000 in Manhattan might get the full federal credit but only a fraction of the state credit.

The credit gets claimed on Form IT-213 when you file your New York return. It’s refundable for most families, meaning you can receive it even if your state tax liability is zero.

How NYC Families Can Maximize Both Credits

Retirement contributions are the most straightforward lever. Putting money into a 401(k) or Traditional IRA lowers your AGI, which can pull you back below the phaseout threshold on either the federal or state side. For a couple earning $410,000, maxing out two 401(k) contributions ($23,500 each for 2025) could bring their MAGI under $400,000 and restore the full federal credit.

Health Savings Account (HSA) contributions work the same way. Family HSA contributions up to $8,550 in 2026 reduce your AGI dollar for dollar.

Self-employed parents in NYC have additional options. SEP-IRA or Solo 401(k) contributions can shelter larger amounts, up to $69,000 in some cases, which creates meaningful distance from the phaseout zone.

Qualifying Child Rules for 2026

The child must be under 17 at the end of the tax year, which means a child who turns 17 on December 31, 2026 does not qualify. They must have a valid Social Security number (not an ITIN) per IRS CTC rules, live with you for more than half the year, and not provide more than half of their own support.

For NYC families with shared custody arrangements, only one parent can claim the credit per child. The parent with whom the child lived for the greater number of nights during the year gets the claim. If it’s exactly equal, the parent with the higher AGI claims. Form 8332 allows the custodial parent to release the claim to the other parent, but that only transfers the dependency exemption and CTC, not head of household status or the earned income credit.

The Refundable Portion: ACTC

Not everyone who qualifies for the child tax credit has enough tax liability to absorb the full $2,000. The Additional Child Tax Credit (ACTC) makes up to $1,700 of the credit refundable for 2026. You need at least $2,500 in earned income to start qualifying for the refundable portion, and the refundable amount equals 15% of your earned income above $2,500, capped at $1,700 per child.

For lower-income NYC families, this refundable piece is often the more valuable part. A single parent earning $30,000 with two children would get the full $4,000 credit but likely see a portion of it paid as a refund through the ACTC rather than as a reduction to taxes owed.
