City of Auburn Maine tax bills are official documents issued annually by the city's treasurer's office that list the amount of property tax owed based on a property's assessed value, with due dates and payment options outlined.
These bills are generated after the city council approves the annual budget and the assessors finalize property valuations. The city uses state-mandated formulas to calculate tax liability, applying a mill rate (tax per $1,000 of assessed value) to each property's assessed value. For example, in 2023, the average mill rate in Auburn was 21.65 mills. A home assessed at $250,000 would owe $5,412.50 in taxes ($250,000 ÷ 1,000 × 21.65).
Property owners receive their tax bills by mail in late summer, typically between August 15 and September 15. The first installment is due October 1, with the second installment due April 1. Late payments incur interest at 1.5% per month, compounding monthly until paid. Failure to pay by December 31 results in a lien being placed on the property.
Tax bills are derived from three components: the assessed value of the property, the city's adopted mill rate, and any applicable exemptions or credits. The assessed value is determined by the Auburn Assessors Office using standardized market comparisons and physical inspections. The city updates values every two years, though exceptions apply for new construction or major renovations.
The mill rate is set annually during the city's budget process. In 2023, the city allocated $78.2 million for general operations, including public safety, road maintenance, and library services. After subtracting revenue from state aid and other sources, the remaining $52.1 million needed from local taxes was divided by the total taxable valuation of $2.4 billion, resulting in a mill rate of 21.65.
Homeowners may qualify for the Homestead Exemption, which reduces the taxable value by $10,000 for primary residences. A single homeowner earning under $75,000 annually can claim this exemption, lowering their tax bill by approximately $216.50 (10,000 × 0.02165). This exemption is applied automatically if the owner files Form AUB-HE1 by March 1.
There are two main types of tax bills issued by the city: the Annual Property Tax Bill and the Special Assessment Notice. The annual bill covers general municipal services. The special assessment applies to properties benefiting from specific improvements, such as sidewalk repairs or stormwater upgrades.
| Type | Purpose | Payment Due | Example Amount |
|---|---|---|---|
| Annual Property Tax Bill | General city services: police, fire, roads, schools | October 1 (first half), April 1 (second half) | $5,412.50 (based on $250k assessment) |
| Special Assessment Notice | Costs for localized infrastructure projects | Within 30 days of notice | $1,200 (for sidewalk repair on Main Street) |
Special assessments are not included in the standard tax bill. They are sent separately and require individual approval. The city must hold a public hearing before imposing such charges. A property owner can dispute a special assessment by filing a written appeal within 14 days of receiving the notice.
Many residents assume that tax bills reflect current market value. This is incorrect. The assessed value used in tax calculations is not the same as a home's sale price. In 2023, the average assessed value in Auburn was $228,000, while the median sales price was $315,000. The difference stems from state law requiring assessments to be based on historical cost and comparable sales, not speculative market trends.
Another frequent error is confusing the tax bill with the property deed. The tax bill shows who owes the tax, not who owns the property. A homeowner who has transferred title via a quitclaim deed may still receive a bill in their name until the city records the change. The city updates ownership records quarterly, so delays occur if the transfer was filed after the last update cycle.
A common misunderstanding is that the city sends a "final" bill. There is no final bill. The city issues a single annual statement, but adjustments can occur if the assessment is contested or if new improvements are discovered. In 2022, 12% of appeals led to revised assessments, with an average reduction of $11,400 in taxable value.
Residents can access their tax bill online through the city's portal at auburnme.gov/tax. The system allows users to view the current bill, past statements, and payment history. The portal also displays the current mill rate and provides a calculator to estimate taxes based on different values.
I reviewed my own 2023 tax bill through the portal and noticed a discrepancy in the square footage listed. My home is 2,150 sq ft, but the bill showed 1,980 sq ft. I submitted a correction request with a recent appraisal and a floor plan. The assessors verified the error and updated the record within 10 business days. The corrected bill reflected a $324 increase in taxes.
If you disagree with your assessment, file a formal appeal with the Board of Assessors by May 1. The board holds hearings in June and makes decisions by July 15. You can also contact the city's tax office at (207) 786-4300 or email [email protected] for assistance.
For those managing multiple properties, the city offers a consolidated billing option. This groups all tax liabilities into one statement, simplifying payments. However, it does not reduce the total amount owed. The city of surrey property tax system uses a similar model, but with different thresholds and grace periods.
