Marketplace financial assistance can depend on an estimate of household income for the coverage year. A change in wages, self-employment income, household size, filing circumstances, or other information may affect the assistance shown in an application. The impact depends on the rules and the details of the situation.
Update information promptly
Use the Marketplace account for your state to report applicable changes. The official process will explain which information is needed and whether the application or plan choices need to be updated. Do not use a general website form to send tax returns or detailed financial records.
Understand advance tax credits
If advance premium tax credits are being paid to the insurer, they are based on estimates and may have to be reconciled on a federal tax return. Accurate, updated information helps reduce the chance of a mismatch between estimated and final figures, though the result depends on the facts and applicable tax rules.
Use official instructions
See HealthCare.gov: report changes and the IRS Affordable Care Act resources. For specific tax consequences, consult a qualified tax professional.
