For purposes of the Premium Tax Credit (PTC), "household income" refers to the modified adjusted gross income (modified AGI) of the taxpayer and their spouse (if filing a joint return), plus the modified AGI of each individual whom the taxpayer claims as a dependent and who is required to file an income tax return because their income meets the income tax return filing threshold. This definition is used to determine eligibility for the PTC and to calculate the credit amount.
Key Components of Household Income
- Taxpayer and Spouse (if applicable): The modified AGI of the taxpayer and their spouse, if filing jointly.
- Dependents Required to File: The modified AGI of any dependents whom the taxpayer claims and who are required to file a tax return due to meeting the income threshold for filing.
- Exclusions: The modified AGI of dependents who are filing only to claim a refund of withheld income tax or estimated tax is not included in household income.
Relevant Tax Rule and Form Reference
The definition of household income is specified in Publication 974, under the section "Terms You May Need To Know | Household income." This information is also referenced in the instructions for Form 8962, particularly in Line 2a and Line 2b, where taxpayers are required to report household income for PTC calculations.
