As of 2024, six U.S. jurisdictions enforce state-level penalties for not having qualifying health : California, Massachusetts, New Jersey, Rhode Island, Vermont, and the District of Columbia. The federal tax penalty for lacking coverage was effectively reduced to $0 in 2019, but these states have maintained or implemented their own mandates, with fines calculated based on state tax returns. The specific penalty structure—a flat fee or a percentage of income—varies significantly by location and year.
California operates under its Individual Mandate. For the 2023 tax year, the penalty is the greater of either a flat fee or a percentage of household income. The flat fee penalty is $900 per adult and $450 per dependent child (with a family maximum of $2,700). Alternatively, it is 2.5% of household income above the state filing threshold. This is one of the most substantial penalties in the nation.
Massachusetts pioneered the state individual mandate with its 2006 healthcare reform. Its penalty is unique and often results in significant charges. For 2023, it is calculated based on half the cost of the lowest-priced ConnectorCare plan available to an individual or family, adjusted for income. This can translate to hundreds of dollars per month of non-coverage, making it potentially more costly than other states' fees.
The following table summarizes the 2023 penalty mechanisms for adults in these jurisdictions:
| State/Jurisdiction | 2023 Penalty Mechanism (for an individual) | Key Characteristics |
|---|---|---|
| California | Greater of: $900 OR 2.5% of income above filing threshold | Family cap applies. A high earner will likely pay the percentage-based penalty. |
| Massachusetts | 50% of the lowest-cost ConnectorCare premium for which one is eligible | Penalty varies monthly; tied to actual insurance market costs. |
| New Jersey | Greater of: $695 OR 2.5% of household income | Modeled closely after the former federal penalty structure. |
| Rhode Island | Greater of: $695 OR 2.5% of household income | Similar to NJ; mandate includes an affordability exemption based on cost of coverage. |
| Vermont | $0 (Filing requirement only) | Has an individual mandate but no financial penalty for non-compliance. Residents must file a form to claim an exemption or report coverage. |
| District of Columbia | Greater of: $695 OR 2.5% of household income | Follows the same structure as NJ and RI. |
Vermont’s case is a critical distinction. While it has a legal mandate, the penalty is $0. However, residents are still required to report their health insurance status on their state tax return and may need to claim an exemption. Failure to file the required form can lead to complications or delays in tax processing.
The primary driver for these penalties is to stabilize the individual insurance market by incentivizing healthier individuals to obtain coverage, which helps spread risk and lower premiums overall. State revenue data indicates these penalties generate tens of millions of dollars annually, which are often reinvested into state affordability programs. For instance, California directs penalty revenue to its subsidy programs, enhancing coverage affordability for low-to-middle-income residents.
You can claim exemptions from these penalties for reasons such as experiencing a financial hardship, having a very short gap in coverage (usually less than three consecutive months), or if the lowest-cost plan available to you exceeds a certain percentage of your household income (typically around 8.3%). The process for claiming an exemption is handled through your state’s tax filing system.

















I live in Massachusetts and work as a freelancer. When I had a gap between a couple of years ago, I let my insurance lapse for about five months, thinking the federal penalty was gone. Come tax time, I got hit with a bill from the state for over $1,200. It was a brutal lesson. The penalty here isn't just a flat fee; it's based on what insurance would have cost. My accountant told me it's calculated monthly, so even a short gap adds up fast. If you're in one of these states, don't assume you're off the hook—check your state's rules specifically.

From a perspective, the state-level health insurance mandate is a material liability that clients often overlook. In California, New Jersey, Rhode Island, and D.C., the penalty can be 2.5% of household income above the filing threshold. For a family with an adjusted gross income of $100,000, that could mean a penalty of over $2,000. Compare that to the cost of a high-deductible Bronze plan, which might be less. The rational economic choice, therefore, is rarely to go uninsured and pay the fine. We advise clients in these states to treat securing minimum essential coverage as a non-negotiable part of their annual tax strategy, similar to making estimated tax payments.

I just moved from Texas to New Jersey for work. Back home, this wasn't even a question. My new HR department explicitly mentioned during onboarding that I needed to have health for the full year or face a state tax penalty. They gave us a sheet comparing the penalty to our plan options. It was a heads-up I appreciated. It's not just a federal thing anymore—it's a very local one. If you're relocating, especially to the Northeast or the West Coast, put "check state health insurance rules" on your moving checklist. The tax surprise is real and entirely avoidable.

Being uninsured is a risk I’ve taken, but now I live in D.C. and learned the hard way that it’s a costly risk here. The penalty isn’t just symbolic. For me, it ended up being a flat $695 because my income was low that year, but I know folks who paid a lot more based on their salary. The system feels like it’s designed to make you just get the . There are exemptions, though. If you’re truly struggling, look into the hardship exemption or see if the cheapest plan costs more than about 8% of your income—you might qualify to avoid the fine. The key is you have to actively file for that exemption on your taxes; they won’t just give it to you.
