This guide is designed for first-pass understanding. Start with core terms, then apply the framework in your own account workflow.
The 1095 series; Form 1095-A, 1095-B, and 1095-C; are the health insurance reporting forms created by the Affordable Care Act. While the federal individual mandate penalty was reduced to $0 starting in 2019 by the Tax Cuts and Jobs Act, these forms remain critically important. Form 1095-A in particular is essential for anyone who received marketplace health insurance subsidies; without it, you cannot properly reconcile your Premium Tax Credit on Form 8962, and you may owe back thousands of dollars or miss out on a substantial refund.
The 1095 forms were created as part of the Affordable Care Act (ACA), signed into law on March 23, 2010. The ACA's individual mandate required most Americans to maintain minimum essential health coverage or pay a tax penalty (the "shared responsibility payment"). To enforce this requirement and administer the Premium Tax Credit, the IRS needed a way to verify who had health coverage and what they paid for it.
Three forms were designed for three different coverage sources:
The forms were first issued for the 2014 tax year (the first year the individual mandate was fully in effect). The initial rollout was bumpy; many taxpayers and employers were confused about the forms, and the IRS extended deadlines multiple times. The employer reporting requirements (1095-B and 1095-C) were delayed by one year, not taking effect until the 2015 tax year.
The Tax Cuts and Jobs Act of 2017 reduced the individual mandate penalty to $0 starting in 2019, effectively eliminating the penalty for not having coverage. However, the 1095 forms were not eliminated; they continue to be issued because the Premium Tax Credit still exists, and several states have enacted their own individual mandates with penalties.
Issued by the marketplace to anyone who enrolled in a marketplace plan. You do not file this form; you receive it. It is typically sent by January 31 following the coverage year. If you received advance Premium Tax Credit payments (subsidies that reduced your monthly premiums), Form 1095-A is essential for completing Form 8962 to reconcile the credit.
Form 1095-A is from the Health Insurance Marketplace (exchange) and is needed to reconcile Premium Tax Credits. Form 1095-B is from insurers or government programs (Medicaid, CHIP, Medicare) confirming you had minimum essential coverage. Form 1095-C is from large employers (50+ employees) reporting the coverage they offered. Only 1095-A is required to file your tax return.
If you received a 1095-A (marketplace coverage with subsidies), yes — you must file Form 8962 to reconcile your Premium Tax Credit. Without it, you cannot accurately report whether you received too much or too little in subsidies. For 1095-B and 1095-C, you should keep them for your records, but you can file without them since the federal individual mandate penalty is $0.
If your actual income was higher than what you estimated when enrolling, you received excess Premium Tax Credits that must be repaid. You reconcile this on Form 8962, attached to your Form 1040. Repayment amounts are capped based on income for those below 400% of the federal poverty level. If your income was lower than estimated, you'll receive additional credit as a refund.

Issued by insurance companies, government programs, and certain small employers. Like 1095-A, this is sent to you; you do not file it. It simply confirms that you (and your covered family members) had minimum essential coverage during the year. The deadline for issuance has been extended to March 2 in recent years.
Issued by ALEs (employers with 50+ full-time employees) to their full-time employees. The form has three parts: Part I identifies the employee and employer; Part II describes the coverage offered each month (using code indicators); and Part III, if applicable, lists the individuals covered under the employer's self-insured plan. This form is due to employees by March 2 and filed with the IRS by February 28 (paper) or March 31 (electronic).
For employers, Forms 1095-B and 1095-C are accompanied by transmittal forms (1094-B and 1094-C) that summarize the information and are filed with the IRS.
The most important columns on Form 1095-A are:
If the advance payments were higher than the credit you are entitled to (because your income was higher than estimated), you must repay the excess. If the advance payments were lower, you receive the difference as a refund.
Part II of Form 1095-C uses code indicators to describe the employer's coverage offer for each month. Line 14 codes describe the type of coverage offered (e.g., Code 1A means minimum essential coverage was offered to the employee only). Line 16 codes describe safe harbors or other conditions the employer relies on for penalty avoidance. These codes are primarily relevant for employer ACA compliance, but they can affect your eligibility for the Premium Tax Credit if you are also a marketplace enrollee.
The most significant recent development is the continued extension and expansion of enhanced Premium Tax Credits. The American Rescue Plan Act of 2021 temporarily increased credit amounts and eliminated the income cap (previously 400% of the federal poverty level). The Inflation Reduction Act of 2022 extended these enhanced credits through 2025. These changes make Form 1095-A and Form 8962 more important than ever for marketplace enrollees.
The IRS has also extended deadlines for issuance of Forms 1095-B and 1095-C multiple times, giving employers and insurers additional time to prepare and distribute the forms. The current deadline for providing forms to individuals is typically in early March, rather than the original January 31 deadline.
For employer reporting, the IRS finalized regulations in 2024 allowing employers to post Forms 1095-C on a secure website instead of mailing them to employees, provided certain notice and consent requirements are met.
