Based on the information in the instruction booklet for the Maine Income Tax Return, you are allowed to use a different filing status on the Maine return from what you used on the Federal return if you are both non-residents of Maine and only one person had income from Maine.
As you go through the Maine return, you can choose to change your filing status. Be aware that changing the filing status so that it is different from your Federal return will require you to mail the Maine tax return. It will not be eligible for electronic filing.
For more information you can take a closer look at the instruction booklet for the Maine Income Tax return by clicking here. The description about how the tax is calculated for non-residents is on page 20.
@Hatfield82 Yes that will be the case if the laws do not change next year. You can find out more information here: https://www.maine.gov/revenue/faq/individual-income-tax
