Military Pay State Income Tax: Maine Rule 807, Safe Harbors and SCRA Rules for US CPA Firms

By Keshav Bansal, CA

Military pay state income tax questions land on CPA desks every time a client is reassigned, deploys or marries a service member, and Maine just updated its rulebook. Maine Revenue Services (MRS) adopted amendments to Rule 807, “Residency” (Reg. 18-125-807), effective October 7, 2026. Per the MRS Tax Alert for October 2026, the rule now clarifies when an individual is treated as a Maine residency safe harbor resident and that certain military compensation a Maine resident earns from Space Force service outside Maine is not taxable to Maine. Bloomberg Tax reported the change on October 13, 2026. Here is how states tax military pay, using Maine as the example.

What Maine changed in Rule 807

The adopted rule (filing 2026-215) adds the Space Force to the list of services in section .08, which explains the resident subtraction under 36 M.R.S. §5122(2)(LL). The statute itself already names the Space Force (PL 2023, c. 523), so the rule now matches the law. The safe harbor section drops older “beginning on or after January 1, 2007” language, and MRS describes the rest as technical changes to enhance clarity.

Maine’s two residency safe harbors

Under 36 M.R.S. §5102(5)(A), a Maine domiciliary is still not a “resident individual” if one of two tests is met. Rule 807 calls these people safe harbor residents.

• General safe harbor: during the tax year the individual did not maintain a permanent place of abode in Maine, maintained one outside Maine, and spent no more than 30 days in total in Maine. Any part of a day counts as a full day. A married individual or one with minor children is presumed to keep a Maine abode if the spouse (unless legally separated) or the minor children live in one in Maine.
• Foreign safe harbor: within any period of 548 consecutive days the individual is present in a foreign country or countries for at least 450 days, is in Maine for no more than 90 days, and does not keep a Maine abode where a spouse or minor child is present for more than 90 days. A prorated cap on Maine days also applies in the years in which the period begins and ends.

A safe harbor is not an exemption. Rule 807 section .02 says a nonresident or safe harbor resident still owes Maine tax on income from work performed in Maine, Maine business income, gains on Maine real or tangible property and Maine rental income.

The federal floor: the Servicemembers Civil Relief Act

Every state’s military rules sit on top of 50 U.S.C. §4001 (SCRA §511). A servicemember neither loses nor acquires a residence or domicile for tax purposes by being absent from or present in a state solely because of military orders (§4001(a)(1)). Military compensation is not treated as income from sources in the duty-station state if the member is not a resident there (§4001(b)). That state also may not use the member’s military pay to increase the tax on other income the member or spouse owes it (§4001(e)).

Rule 807 applies this directly. Maine will not tax the military income of a nonresident stationed in Maine, or that person’s intangible income such as interest and dividends. Wages from a non-military job in Maine and income from operating a business in Maine are taxable. Maine’s statutory-residency test (a Maine abode plus more than 183 days) also carves out members of the U.S. Armed Forces. The duty-station state protects military pay, but it can tax civilian and business income earned there.

DD Form 2058 and the home state

DD Form 2058, “State of Legal Residence Certificate,” tells the military pay system which state’s income tax to withhold. Its instructions say a change of legal residence generally takes physical presence in the new state, a simultaneous intent to make it a permanent home and abandonment of the old one. “Home of record” is a separate concept used for travel allowances. DFAS says changes go through the pay office and are not retroactive for the year. Rule 807 says a completed DD Form 2058 is evidence of a change in domicile.

Federal law stops the duty-station state from taxing the pay. The home state keeps the right to tax it, and each home state decides whether to exempt it. Maine subtracts military compensation earned by a resident for service outside Maine under written orders in two cases:

• active duty in the active components of the Army, Navy, Air Force, Marines, Coast Guard or Space Force, with a permanent duty station outside Maine; and
• active duty in the active or reserve components, or in the Maine National Guard, in support of a federal operational mission or a declared state or federal disaster response. Rule 807 limits “federal operational mission” to support of overseas deployment and excludes standard duty such as training and administrative activities.

A Maine domiciliary stationed elsewhere stays domiciled in Maine, though Rule 807 notes that the safe harbors may apply to a service member or spouse who meets the requirements.

Military spouses: MSRRA and the 2023 election

The Military Spouses Residency Relief Act (Pub. L. 111-97, Nov. 11, 2009) extended residence protection to spouses, and Pub. L. 115-407 (Dec. 31, 2018) added a spouse election. The Veterans Auto and Education Improvement Act of 2022 (Pub. L. 117-333, Jan. 5, 2023) rewrote the rule. A spouse neither loses nor acquires a tax residence by being in a state solely to be with the servicemember under orders (§4001(a)(2)). For any taxable year of the marriage, the couple may elect the servicemember’s residence, the spouse’s residence or the servicemember’s permanent duty station (§4001(a)(3)). Under §4001(c), a qualifying spouse’s wages are not source income of the state where they are earned.

Rule 807 section .08B tracks the spouse protections. Its election sentence still cites 50 U.S.C. §4001(a)(2)(B), the 2018-era paragraph that Pub. L. 117-333 replaced, so check current MRS forms and instructions before relying on the broader election for a Maine return.

Checklist for US CPA firms

• Intake: record the client’s legal residence, the state on DD Form 2058, permanent duty station and the spouse’s claimed state each year.
• Income split: separate military pay from civilian wages, side businesses and rentals in the duty-station state.
• Home-state rules: confirm what the home state exempts (Maine’s §5122(2)(LL) is specific about components, duty station and orders).
• Safe harbors: log days in Maine and abode facts for Maine domiciliaries living elsewhere.
• Spouses: document the §4001(a)(3) election and confirm how each state implements it.
