Your Guide to State Individual Mandates in ACA Reporting

Note: The deadlines below reflect the 2026 tax year (2027 filing season) based on current IRS patterns and state guidance. Final dates are confirmed each fall when the IRS releases official instructions. Always verify with the latest official guidance before filing.

If your organization employs people in more than one state, you already know how complex benefits compliance can be. State individual mandates in ACA reporting add another layer—one that often catches HR managers off guard. Having even one employee or covered individual who resides in a mandate jurisdiction may require an employer, insurer, plan sponsor, or other coverage provider to evaluate state reporting obligations. The entity responsible for filing often depends on the jurisdiction, employer size, plan funding arrangement, and who provided the coverage.. We put this guide together to help you understand which states have mandates, what they require, and how to stay ahead of deadlines so you can support your people with confidence. 

What Is the ACA Individual Mandate? 

The ACA individual mandate (also known as the "individual shared responsibility provision") requires most Americans to have qualifying health insurance, known as minimum essential coverage (MEC). The mandate became law in March 2010 as part of the Affordable Care Act (ACA). Originally, if individuals did not have proof of health insurance when they filed their taxes, the IRS assessed penalties. 

In December 2017, Congress reduced the federal individual shared responsibility payment to zero, effective for coverage months beginning January 1, 2019. Although the federal statutory coverage requirement remains, individuals generally no longer owe a federal payment for failing to maintain minimum essential coverage. 

Why States Created Their Own Mandates 

Since the federal penalty was reduced to zero, some states have turned to state individual mandates to help keep their healthcare marketplaces stable. Since the federal penalty was reduced to zero, some states have adopted individual mandates to support participation in the health insurance market and promote market stability. . These state mandates also created state-level reporting requirements that mirror, but are separate from, federal ACA reporting. 

Which States Have Individual Healthcare Mandates? 

To date, California, the District of Columbia, Massachusetts, New Jersey, Rhode Island, and Vermont have passed state individual mandates. With each state passing its own individual mandate, it may make it more challenging for companies to keep up with all the different regulations and reporting requirements. 

Essentially, having even one employee or covered individual who resides in a mandate jurisdiction may require an employer, insurer, plan sponsor, or other coverage provider to evaluate state reporting obligations. The responsible filing entity depends on the jurisdiction, employer size, plan funding arrangement, and who provided the coverage.. This means companies must be ACA compliant at the federal level and at the individual state levels. It is possible that additional states may consider their own healthcare mandates in the future, including Hawaii, Washington, Connecticut, Minnesota, and Maryland, although there has not been recent traction. 

Below is some general information for each state that currently has an individual healthcare mandate. 

California Individual Mandate 

History of Legislation 

The State of California's individual mandate, requiring residents to have qualifying coverage throughout the year, went into effect January 1, 2020. The individual mandate bill SB-78 was signed into law on July 2, 2019. 

Important Dates 

Employers are required to file health coverage information annually by March 31 following the coverage year but tax year requirements should also be confirmed when final federal and state guidance is released. For the 2026 tax year, the employee Form 1095-C furnishing deadline is January 31, 2027, but there is no penalty assessed if the form is furnished by the federal deadline of approximately March 2, 2027. California also offers an automatic penalty-free extension through May 31, 2027. 

Employer Obligations 

In-state and out-of-state employers who employ California residents are obligated to provide the same data outlined in Section 6055 of the Affordable Care Act. This section specifically covers the enrolled coverage of employees, while Section 6056 covers the offer of coverage to employees. For fully insured coverage, the insurer will generally be the coverage provider responsible for reporting enrollment information. Employers should confirm that the insurer will complete the applicable California filing. 

California Individual Mandate Penalties 

After the May 31 deadline, the FTB may assess a penalty of $50 per individual who was provided with coverage but not reported. This means if an employer has only one employee in California, they would need to comply with the California individual mandate reporting for that employee. Californians who do not have health insurance coverage and are not exempt will also owe an individual penalty. 

Process for Filing in California 

An employer that offers health coverage through a self-insured health plan must report information about each individual enrolled in such coverage. This information must be reported on federal Form 1095-C, Part III, for any employee who is enrolled in coverage (and any spouse or dependent of that employee). Employers who offer health coverage through a fully insured health plan can rely on their insurer to report information about each individual enrolled in such coverage. Employers with 10 or more information returns must file electronically through California's FTB file exchange. 

District of Columbia Individual Mandate 

History of Legislation 

The District of Columbia (D.C.) individual mandate, requiring residents to have qualifying coverage throughout the year, went into effect on January 1, 2019. The Individual Tax Payer Health Insurance Responsibility Requirement was signed into law on June 26, 2018. 

Important Dates 

Employers are required to report annually, within 30 days after the IRS deadline for submitting 1095-B or 1095-C forms, including any extensions granted by the IRS. For the 2026 tax year, that puts the D.C. filing deadline at approximately April 30, 2027. The employee Form 1095-C furnishing deadline is the same as the federal deadline, approximately March 2, 2027. 

Employer Obligations 

The legislation applies to in-state and out-of-state employers who withhold and pay payroll tax to D.C. or who employ D.C. residents, even if the employer does not withhold D.C. payroll taxes. D.C. reporting applies to applicable entities identified under D.C. law, including certain employers and plan sponsors with at least 50 full-time employees and at least one D.C.-resident employee, as well as persons that provide minimum essential coverage to a D.C. resident. Applicability should be evaluated based on both employer status and the entity responsible for providing coverage. In short, if an ALE is sending 1095-C forms to employees and filing 1095-C and 1094-C forms with the IRS, they are required to file forms with the state. Employers who only have fully insured coverage cannot rely on the insurer to provide 1095-B forms alone—they will still need to submit 1095-C and 1094-C forms to D.C. 

D.C. Individual Mandate Penalties 

D.C. residents who do not have health insurance coverage and are not exempt will owe a penalty. For recent tax years, the D.C. penalty has been the greater of two amounts: a flat fee per adult (and a reduced fee per child) or a percentage of household income. Check the latest D.C. Office of Tax and Revenue guidance for the current year's penalty amounts. 

Process for Filing in D.C. 

D.C. leverages its mytax.dc.gov portal using the Office of Tax and Revenue's prescribed file format. The format is a delimited file with an extension of .txt. This differs from the IRS format, which is an XML file. While D.C. indicates this is the same information provided to the IRS, for employers who employ non-D.C. residents, they must only include requested information in the file. Upon submission, a confirmation email will be provided. 

Frequently Asked Questions 

Will D.C. provide feedback like the IRS, such as "accepted," "accepted with errors," or "rejected"? 

MyTax.DC.gov does not generate an acknowledgment like the IRS's Affordable Care Act (ACA) Information Returns (AIR) System. Instead, applicable entities and third-party service providers will be notified if there are errors when they attempt to upload a file. If there are no errors, the bulk file upload will indicate "processing" until "accepted." 

If you replace or correct files with the IRS, should these files be shared with D.C.? 

Yes. Applicable entities and third-party service providers can upload a correction file. However, only one correction file can be filed per business day. No files will be accepted after December 31 of the filing year. Check the latest D.C. Office of Tax and Revenue guidance for additional clarification and information. 

Massachusetts Individual Mandate 

History of Legislation 

The State of Massachusetts' individual mandate, requiring residents to have qualifying coverage throughout the year, went into effect in 2006 and predates the Affordable Care Act. Massachusetts residents must maintain creditable health coverage or qualify for an exemption under state law. 

Important Dates 

Massachusetts has two separate reporting frameworks that employers may need to be aware of: 

• Form MA 1099-HC reporting, which provides proof of health insurance coverage for Massachusetts residents. Applicable furnishing and filing deadlines should be confirmed using the current year's Massachusetts Department of Revenue instructions. [mass.gov] 
• Health Insurance Responsibility Disclosure (HIRD) reporting, which is administered through MassTaxConnect. The HIRD filing window generally opens on November 15 and closes on December 15 each year. 

Employer Obligations 

Massachusetts differs from many of the states that adopted individual mandates after the ACA. For health coverage reporting, insurance carriers generally issue Form MA 1099-HC to covered Massachusetts residents and submit the required information to the Massachusetts Department of Revenue. Employers should confirm reporting responsibilities with their carrier, third-party administrator, or benefits advisor, particularly if they sponsor a self-funded arrangement. In addition, Employers with six or more Massachusetts employees must also file a Health Insurance Responsibility Disclosure (HIRD) form through MASSTAXConnect. The HIRD form collects employer-level information about employer-sponsored insurance (ESI) offerings and helps MassHealth identify individuals who may have access to employer-sponsored coverage. 

Massachusetts Individual Mandate Penalties 

Massachusetts residents who do not maintain creditable health coverage and do not qualify for an exemption may be subject to a state individual mandate penalty. Massachusetts residents who do not maintain creditable health coverage and do not qualify for an exemption may be subject to a state individual mandate penalty. Employers should consult current Massachusetts guidance regarding any penalties associated with applicable employer reporting requirements. Employers should consult current Massachusetts guidance regarding any penalties associated with employer reporting obligations. 

New Jersey Individual Mandate 

History of Legislation 

New Jersey's individual mandate, requiring residents to have qualifying coverage throughout the year, went into effect on January 1, 2019. It was signed into law on May 30, 2018. The state released reporting requirements in June 2019. 

Important Dates 

Employers are required to report annually by the federal deadline, which is usually March 31 or the closest business day as advised by the IRS. For the 2026 tax year, the employee Form 1095-C furnishing deadline is approximately March 2, 2027, and employers must transmit coverage forms to the New Jersey Division of Taxation by March 31, 2027. 

Employer Obligations 

In-state and out-of-state employers who employ New Jersey residents are obligated to report, even if the employer does not withhold New Jersey payroll taxes. New Jersey requires employers, insurers, and other coverage providers responsible for reporting minimum essential coverage to submit the applicable coverage information for full-year and part-year New Jersey residents. The party responsible depends on the coverage arrangement; the requirement is not limited to employers that withhold New Jersey payroll taxes or to ALEs in every circumstance. 

It’s important to clarify that New Jersey: 

• requires affirmative distribution to each applicable primary enrollee; 
• does not accept a Form 1095-C containing only Parts I and II as satisfying its coverage-reporting requirement; 
• accepts a fully completed Form 1095-C or one containing Parts I and III, among other permitted forms. 

New Jersey Individual Mandate Penalties 

If a person fails to have health coverage or does not qualify for an exemption, they will be required to make a Shared Responsibility Payment. 

Process for Filing in New Jersey 

New Jersey leverages the same secure transport system that is used by employers or their vendors to submit W-2 forms. Called "MFT SecureTransport" or "Axway," vendors or ALEs must sign up with an account in order to be authorized to submit forms. Paper filing is not available. 

Rhode Island Individual Mandate 

History of Legislation 

Rhode Island's individual mandate, requiring residents to have qualifying coverage throughout the year, went into effect on January 1, 2020. It was signed into law in 2019. 

Important Dates 

Employers are required to report annually by the federal deadline, March 31. For the 2026 tax year, the state electronic filing submission is due March 31, 2027. The employee Form 1095-C furnishing deadline is also the same as the federal deadline March 2, 2027. 

Employer Obligations 

Applicable entities report required coverage information electronically to the Rhode Island Division of Taxation. Rhode Island provides flat-file instructions and accepts IRS forms that contain the information required under state law. 

Rhode Island Individual Mandate Penalties 

Rhode Island residents who do not have health insurance coverage and are not exempt will owe a penalty. 

Vermont Individual Mandate 

History of Legislation 

Vermont's individual mandate, requiring residents to have qualifying coverage throughout the year, went into effect on January 1, 2020. 

Important Dates 

Vermont currently does not impose a separate state employer coverage-reporting requirement. Employers remain subject to applicable federal ACA reporting requirements. 

Employer Obligations 

None, so long as the federal requirement to distribute 1095-C forms remains. Vermont has indicated that employer reporting is not required as long as the federal requirement to distribute 1095-C forms stays in place. 

Vermont Individual Mandate Penalties 

Vermont does not currently impose a state financial penalty on individuals for failure to maintain coverage. Federal employer reporting penalties may still apply when federal reporting requirements are not satisfied. 

How to Stay Ahead of State Individual Mandates in ACA Reporting

Managing state individual mandates in ACA reporting does not have to be overwhelming. We help HR teams streamline compliance by centralizing federal and state-level reporting into one clear, manageable process. Here are a few proactive steps you can take: 

• Map your workforce by state. Identify every employee who resides in a mandate state, including remote and hybrid workers. Employee residence—not employer location—determines your reporting obligation. 
• Confirm your funding arrangement. Fully insured employers can often rely on their carrier for state submissions, but self-insured employers bear the full responsibility of filing directly. Always confirm with your carrier, TPA, or ACA vendor. 
• Track state-specific deadlines. Many state deadlines align with federal timing, but some do not. Build a calendar that captures each state's furnishing and filing dates. 
• Leverage technology. The right reporting platform can automate data collection and filing across multiple states, reducing manual effort and the risk of penalties.
