Washington County Property Tax Appeal, Maine

Travis Bunn·Updated July 22, 2026

Washington County is Maine's easternmost county, known as 'Sunrise County,' with its county seat in Machias. With a population of approximately 31,095, it is Maine's third-least populous county, encompassing two cities (Calais and Eastport), 39 towns, and extensive coastal territory along the Canadian border. Property tax appeals matter here because Washington County has the lowest property tax burden in Maine, with a median annual bill of just $1,065, significantly below the state median of $2,926 and the national median of $2,400. The county's effective tax rate of 1.04% and median home value of $102,300 mean that even modest assessment errors can result in years of overpayment for homeowners in this rural, economically sensitive region where property values have risen 42.6% year-over-year as of early 2025.

On the typical Washington County home, valued near $102,300 at the county’s effective tax rate of 1.04%, an over-assessment of even 10% means you are overpaying year after year until you appeal it. Here is how to find out if yours qualifies.

2026 Appeal Deadline: 185 days from the date of commitment, or December 31, whichever is later

Maine law gives property owners 185 days from the municipality's tax commitment date (when tax bills are sent to the collector, typically late summer/early fall) to file an abatement application with the local assessor. If the 185-day period extends beyond December 31, the deadline becomes December 31. This is one of the longest appeal windows in the United States. Check your tax bill or contact your municipal office for the exact commitment date for your town.

How Washington County Assesses Property

100%of market value

Assessed by: Municipal Assessors (town/city level)

Assessment cycle: annual

Notices typically mailed: Late summer to early fall (varies by municipality)

In Washington County, Maine assesses property at 100% of fair market value as of April 1st each year. Each municipality employs its own assessor who determines property values annually. For example, if your home's market value is $102,300 (the county median), at Maine's 100% assessment ratio your assessed value would be $102,300, resulting in approximately $1,064 in annual taxes at the county's effective rate of 1.04%. Unlike some states, Maine does not use a reduced assessment ratio, what your home would sell for is what you're taxed on.

The Appeal Process

Appeals are heard by the Board of Assessment Review. The Board of Assessment Review conducts a public hearing where both you and the assessor present written and/or oral testimony. Hearings typically last 15-30 minutes. The Board will issue a written decision within 60 days, though they may take longer.

Step 1: Contact your municipal assessor for an informal review. Discuss your concerns about your assessment and request comparable sales data. Many disputes are resolved at this stage without formal filing.

Step 2: If informal review does not resolve the issue, file a written abatement application with your municipal assessor within 185 days of the tax commitment date. State the specific amount you believe your property is worth and provide supporting evidence.

Step 3: The assessor will review your application and either approve or deny it, typically within 60 days. If the assessor does not respond within 60 days, the application is deemed denied.

Step 4: If denied or if you receive an unsatisfactory decision, appeal to the Board of Assessment Review within 60 days of receiving the assessor's decision (or 60 days from the deemed denial). The Board will schedule a hearing where you present evidence.

Step 5: If the Board of Assessment Review denies your appeal, you may appeal to Superior Court within 30 days of the Board's decision. For non-residential properties valued over $1 million, you may appeal to the State Board of Property Tax Review within 60 days.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Washington County?

In Washington County, you must file a written abatement application with your municipal assessor within 185 days from the date of tax commitment, or by December 31, whichever is later. The commitment date is when your municipality officially commits the tax roll to the tax collector, typically occurring in late summer or early fall when tax bills are mailed. This is one of the longest appeal windows in the United States, giving you ample time to gather comparable sales data and build a strong case. Contact your town office to confirm the exact commitment date for your municipality, as it varies by town.

How do I file a property tax appeal in Washington County, Maine?

Washington County uses municipal-level assessment, so you file your appeal with your town or city assessor, not at the county level. Start with an informal discussion with your local assessor to review your concerns, many issues are resolved at this stage. If that doesn't work, submit a written abatement application within 185 days of the tax commitment date, clearly stating the value you believe is correct and providing supporting evidence such as comparable sales, photos, or a professional appraisal. Applications can typically be submitted by mail, in person at your town office, or sometimes by email. Each municipality in Washington County has its own assessor and process, so contact your town office for specific forms and procedures.

What is the homestead exemption worth in Washington County?

The Maine Homestead Exemption reduces your home's assessed value by $25,000 for property tax purposes. In Washington County, where the effective tax rate is 1.04%, this exemption saves approximately $260 per year. To qualify, you must be a permanent Maine resident who has owned a home in Maine for at least 12 months before April 1 and occupy the property as your permanent residence on April 1. The exemption is not automatic, you must file an application with your municipal assessor by April 1. Once approved, the exemption continues automatically as long as you remain eligible and occupy the home. This is separate from and can be combined with veteran or blind exemptions.

What happens at a Board of Assessment Review hearing in Washington County?

If your municipal assessor denies your abatement request, you can appeal to your town's Board of Assessment Review within 60 days. The Board conducts a public hearing where both you and the assessor present evidence and testimony. You'll typically have 15-30 minutes to present your case, including comparable sales data, photographs, appraisals, or other documentation supporting your claimed value. The Board members will ask questions and review all evidence submitted. The hearing is less formal than court but follows structured procedures. After the hearing, the Board issues a written decision within 60 days (though sometimes longer) that can uphold, reduce, or even increase your assessment. Bring multiple copies of all evidence and be prepared to answer questions about your property's condition, features, and how it compares to similar homes.

How much can I save by appealing my property taxes in Washington County?

The potential savings depend on how much your property is overassessed. In Washington County, with an effective tax rate of 1.04%, every $10,000 reduction in assessed value saves you $104 per year. For example, if your home is assessed at $120,000 but comparable sales support a value of $100,000, a successful appeal would save you $208 annually. Over a 10-year period, that's $2,080 in savings. Given that the county's median home value is $102,300, even a 5-10% assessment reduction on a median-value home could save $53-$106 per year. While Washington County has the lowest property tax bills in Maine, successful appeals still provide meaningful savings, especially compounded over multiple years and considering recent 42.6% year-over-year value increases in some areas.

What evidence do I need for a Washington County property tax appeal?

The most powerful evidence for a Maine property tax appeal is comparable sales data, ideally 3-5 similar homes that sold within the past 12 months in your area for less than your assessed value. Include sale dates, addresses, square footage, and sale prices. A recent professional appraisal (within 12-24 months) carries significant weight. Photographs documenting property defects, needed repairs, or adverse conditions (water damage, structural issues, outdated systems) help support a lower value. Written repair estimates from licensed contractors provide concrete evidence of deferred maintenance costs. If your property record contains errors (wrong square footage, incorrect number of bedrooms, listing features you don't have), bring documentation proving the mistakes. Assessment appeals in Maine focus on market value, not affordability, so evidence must show your property is worth less than the assessed amount, not that taxes are too high.

Can veterans get additional property tax relief in Washington County?

Yes, Maine offers veterans a $6,000 reduction in assessed value in addition to the standard $25,000 homestead exemption. To qualify, you must be a wartime veteran who is either age 62 or older, receiving 100% VA disability compensation, or became 100% disabled while serving. This stacks with the homestead exemption for total savings of approximately $323 per year in Washington County (based on the 1.04% effective rate). Paraplegic veterans who received federal specially adapted housing grants qualify for a much larger $50,000 exemption, saving roughly $520 annually. Surviving unremarried spouses, minor children, and parents of deceased veterans may also qualify. All veteran exemptions require an application filed with your municipal assessor by April 1. Contact your town office for the specific application form and documentation requirements.

Why are property assessments in Washington County increasing when the economy is struggling?

Washington County has experienced significant property value increases recently, with some areas seeing 42.6% year-over-year appreciation as of early 2025, despite being one of Maine's most rural and economically challenged counties. This is driven by several factors: increased demand for coastal and rural properties from remote workers and retirees, limited housing inventory, and pandemic-era migration from urban areas. Municipal assessors are required by Maine law to assess properties at 100% of fair market value as of April 1 each year, regardless of local economic conditions or residents' ability to pay. The state audits municipalities annually to ensure assessments reflect actual market values. If recent sales in your area show lower values than your assessment, you have strong grounds for appeal. The 185-day appeal window gives you time to gather comparable sales evidence demonstrating your assessment exceeds true market value.
