2019 Child Tax Credit Calculator

Instantly calculate your Child Tax Credit based on the official 2019 IRS rules. Find out how your income, filing status, and number of dependents affect your eligibility and credit amount.

What is the 2019 Child Tax Credit?

The Child Tax Credit (CTC) is a significant tax benefit designed to help families offset the costs of raising children. For the 2019 tax year, the Tax Cuts and Jobs Act (TCJA) made important changes, increasing the credit amount and modifying the income limitations. This made the credit accessible to more families than in previous years. To accurately calculate child tax credit using 2019 income, taxpayers needed to consider their income, filing status, and the number of qualifying children.

A qualifying child for the 2019 tax year had to be under the age of 17 at the end of the year, be a U.S. citizen, and be claimed as a dependent on the taxpayer’s return, among other criteria. This calculator helps you navigate these rules to provide a clear estimate of your credit.

2019 Child Tax Credit Formula and Explanation

The calculation for the 2019 Child Tax Credit follows a specific formula that accounts for income-based phase-outs. Understanding this is key to correctly calculating your potential credit.

The basic formula is:

Final Credit = (Number of Children × $2,000) - Reduction Amount

The “Reduction Amount” only applies if your Modified Adjusted Gross Income (MAGI) is above a certain threshold. The credit is reduced by $50 for every $1,000 (or fraction thereof) that your income exceeds the limit. Our tax credit phase out calculator feature automates this complex part of the calculation.

Key variables used to calculate the Child Tax Credit for 2019.

Variable	Meaning	Unit / Value (2019)	Typical Range
Number of Children	The count of qualifying dependents under age 17.	Integer	0 – 10+
Credit per Child	The maximum credit amount available per child.	$2,000	Fixed at $2,000
AGI	Adjusted Gross Income from your tax return.	US Dollars ($)	$0 – $500,000+
Income Threshold	The AGI level where the credit begins to phase out.	$400,000 (MFJ) / $200,000 (Others)	Fixed values
Reduction Rate	The amount the credit is reduced per $1,000 over the threshold.	$50	Fixed at $50

Practical Examples

Example 1: Married Couple Below the Threshold

• Inputs: Married Filing Jointly, AGI of $150,000, 2 children.
• Calculation: Since their AGI is well below the $400,000 threshold, they are eligible for the full credit.
• Results: 2 children × $2,000/child = $4,000 Total Credit.

Example 2: Single Filer Above the Threshold

• Inputs: Single Filer, AGI of $215,500, 1 child.
• Calculation: Their AGI is $15,500 above the $200,000 threshold. The excess is treated as 16 increments of $1,000 (since it’s any fraction thereof). The reduction is 16 × $50 = $800.
• Results: $2,000 (potential credit) – $800 (reduction) = $1,200 Total Credit.

Key Factors That Affect the 2019 Child Tax Credit

• Adjusted Gross Income (AGI): This is the most critical factor. The higher your income goes above the threshold, the lower your credit becomes until it is completely phased out.
• Filing Status: Your filing status sets the income threshold. Married couples filing jointly had a $400,000 threshold in 2019, while all other filers had a $200,000 threshold.
• Number of Children: The total credit is a direct multiple of your qualifying children ($2,000 each) before any income limitations are applied.
• Child’s Age: To qualify for the 2019 credit, the child must have been under 17 at the close of the tax year.
• Child’s Residency and Citizenship: The child must be a U.S. citizen, U.S. national, or U.S. resident alien to qualify.
• Refundable Portion (ACTC): For 2019, up to $1,400 of the credit per child was refundable as the Additional Child Tax Credit (ACTC) for eligible taxpayers, meaning you could get a refund even if you didn’t owe any tax. This was dependent on having earned income of at least $2,500. Learn more about refundable tax credits here.

Frequently Asked Questions (FAQ)

What were the exact income limits for the 2019 Child Tax Credit?

For 2019, the credit began to phase out for taxpayers with a Modified AGI over $400,000 for married couples filing jointly and $200,000 for all other filers (Single, Head of Household).

Was the 2019 Child Tax Credit refundable?

Partially. Up to $1,400 per child could be refunded through the Additional Child Tax Credit (ACTC). This required a taxpayer to have at least $2,500 in earned income.

Did my child need a Social Security Number?

Yes. For the 2019 tax year, a qualifying child needed a valid Social Security Number (SSN) to be claimed for the Child Tax Credit.

What if my income was very high?

Your credit would be reduced and eventually eliminated. The credit reduces by $50 for each $1,000 your AGI is over the threshold. For a single child, the credit would fully disappear at an AGI of $240,000 for a single filer or $440,000 for a married couple. If you need a more general tool, try our income tax estimator.

Can I still claim the 2019 credit now?

The deadline to claim a refund for the 2019 tax year was in mid-2023. You can no longer file a 2019 return to claim this credit as a refund.

How was a ‘qualifying child’ defined for 2019?

A qualifying child had to meet several tests: relationship (son, daughter, stepchild, etc.), age (under 17), residency (lived with you for more than half the year), and support (did not provide more than half of their own support).

What is the difference between a tax credit and a tax deduction?

A tax credit reduces your tax liability dollar-for-dollar, making it more valuable than a deduction. A deduction only reduces the amount of your income that is subject to tax.

How did the 2019 rules compare to the 2021 changes?

The 2021 American Rescue Plan Act temporarily and significantly expanded the credit, making it fully refundable, increasing the amounts, and raising the age limit. The 2019 rules, which this calculator is based on, were more restrictive. Our guide on tax law changes provides more context.
