If you did not have healthcare coverage then you could face a tax penalty under the Affordable Care Act, known as the "Shared Responsibility Payment." But this is not true for everyone, especially low-income households.
In Maine, if you cannot pay your tax bill for the property you live on, there is something you can do. Your city or town can decide that you don't have to pay some or all of it. This is called a "poverty tax abatement."
