The term "tax family" in the context of the Premium Tax Credit (PTC) refers to the individuals you are required to include when determining your eligibility for and calculating the amount of the PTC. For 2025, your tax family includes yourself, your spouse (if married), and any dependents you claim on your federal tax return. This group is used by the Marketplace to estimate your PTC based on projected household income and family size.
Who Is Included in Your Tax Family?
- Yourself — You must be an applicable taxpayer (meeting income, filing status, and residency requirements).
- Your spouse — If married at the end of the year, you generally must file a joint return to qualify, though exceptions exist.
- Your dependents — Individuals you claim as dependents on your tax return, including children or other qualifying relatives.
Important Considerations
- Enrollment Certification — When enrolling in a Marketplace plan, you must certify to the Marketplace the number of individuals in your tax family. This affects your APTC (Advance Payment of the Premium Tax Credit) amount.
- Changes in Circumstances — If someone you certified as part of your tax family is not actually included in your tax return (e.g., a child you claimed at enrollment but not on your return), you must report any APTC paid for that individual on Form 8962, following the instructions for “Individual you enrolled who is not included in a tax family.”
- Policy Allocation — If a single health plan covers individuals from multiple tax families, you may need to allocate premiums and APTC amounts between tax families using Form 8962, Line 9, and Table 3 instructions.
