State tax filing

Since the property was located in Maine, you will have ME- source income related to the sale.

However, you may be able to receive a refund of your ME withholdings if the home qualifies for the federal home gain exclusion. If it does not qualify, you will need to report the sale on an ME nonresident state income tax return but you will be able to take a create for these ME state income taxes on your MI resident state income tax return.

You may be can take the gain exclusion as long as you considered the home your "primary residence" for 2 of the last 5 years.  You could live in it for two years and then rent it for three years and then sell it (so long as it is sold within the five year mark from when you first lived in it as your primary residence). If you have a capital gain from the sale of your main home, you may qualify to exclude up to $250,000 of that gain from your income. You may qualify to exclude up to $500,000 of that gain if you file a joint return with your spouse. 

See  Sale of Your Home for more information on the exclusion.

If you meet the exclusion, in order to get the full refund of your ME state income tax withholdings, you will need to file a nonresident ME return but report zero "0" income from ME. You must mail in this ME nonresident state income tax return and include a copy of your federal return. You will want to include an explanatory statement with your ME return stating your situation (that your ME home sale qualifies for the federal gain exclusion and therefore your ME withholdings were held in error).

According to the ME Department of Revenue;

Maine Law requires, at the time of closing, a buyer to withhold 2.5% of the consideration price ($50,000 or more) from any nonresident individual, estate or business. This 2.5% withholding is an estimated tax payment to ensure that a seller complies with Maine income tax responsibilities.

The Maine real estate withholding amount is merely an estimate of the income tax due on the gain from the sale of the Maine property. A Maine income tax return must be filed to determine the actual tax due on the gain and whether or not a refund is due to you. In some cases, an additional amount may be due with the Maine income tax return filed.

However, Form REW-5 must be completed to request an exemption or a reduction in the real estate withholding amount. Exemptions are generally granted when there is a loss on the sale of the property, a federal exclusion of the gain on the sale of a principal residence, the transaction involves a like-kind exchange, or for other situations resulting in no Maine income tax liability

For the sale of personal residence

You will not be allowed to take a capital loss for a personal use capital asset. Also there is no reporting requirement if the property meets the home gain exclusion (unless you received a 1099-S).

You can take the gain exclusion as long as you considered the home your "primary residence" for 2 of the last 5 years. If you have a capital gain from the sale of your main home, you may qualify to exclude up to $250,000 of that gain from your income. You may qualify to exclude up to $500,000 of that gain if you file a joint return with your spouse
