How Property Tax Works

York County, Maine operates under a decentralized property tax system where individual municipalities within the county set their own tax rates and collect property taxes to fund local services including schools, public safety, road maintenance, and municipal operations. Property taxes are assessed based on the fair market value of real estate and personal property as of April 1st each year. The effective tax rate in York County varies significantly by municipality, typically ranging from approximately 0.8% to 1.4% of assessed value, with Maine's statewide average around 1.2%.

Property tax rates vary considerably within York County due to different municipal needs, school district funding requirements, and special taxing districts. Municipalities like Kittery, York, Wells, Kennebunk, Biddeford, Saco, and others each establish their own mill rates annually. Some areas may have additional assessments for special districts such as sewer districts, fire districts, or tax increment financing (TIF) districts. Property owners should verify their specific municipal rate and any applicable district assessments, as these can significantly impact the total tax burden.

Supplemental Tax Bills

Supplemental taxes in York County municipalities are additional property tax bills issued when there are mid-year changes to property ownership, improvements, or assessments. Common triggers include new construction completion, major renovations that increase property value, subdivision of land, or corrections to previous assessments. When new construction is completed after April 1st (Maine's assessment date), municipalities may issue a supplemental bill for the partial year.

Supplemental taxes are calculated by applying the current mill rate to the change in assessed value, prorated for the portion of the tax year remaining. For example, if a $100,000 addition is completed on July 1st in a municipality with a $20.00 mill rate, the supplemental tax would be: ($100,000 ÷ $1,000) × $20.00 × (9 months ÷ 12 months) = $1,500. Property owners typically receive supplemental bills 30-60 days after the triggering event, with payment usually due within 30 days of the bill date.

Escrow & Property Taxes

Most mortgage lenders in York County require borrowers to escrow property taxes, collecting monthly payments as part of the mortgage payment and paying taxes directly to municipalities on behalf of homeowners. Lenders typically collect 1/12th of the annual tax bill each month, plus an additional 1-2 months as a cushion. Maine law requires tax bills to be paid in two installments, with due dates varying by municipality but commonly September 15th and March 15th.

Property owners with escrowed taxes should verify their lender has current tax information and is making timely payments. Lenders must provide annual escrow statements showing deposits, payments, and account balance. If property taxes increase due to revaluation or mill rate changes, lenders may adjust monthly escrow amounts and may require a one-time shortage payment. Property owners can contact their municipality's tax office to confirm payments have been received and verify their account status.

Q: When are property taxes due for FY 2025-2026? A: Due dates vary by municipality in York County. Most municipalities have two payment dates, commonly around September 15th and March 15th, though some may use October 1st and April 1st. Contact your specific municipality for exact due dates.

Q: What is the Homestead Exemption and how do I apply? A: Maine's Homestead Exemption reduces your taxable assessed value by up to $25,000 for your primary residence. You must apply with your municipal assessor's office by April 1st for the tax year. This is not automatic and requires annual application for first-time applicants.

Q: Are there property tax credits available for seniors? A: Maine offers a Property Tax Fairness Credit for eligible residents, including seniors, based on income and property taxes paid. This is a state income tax credit that requires filing Maine income tax forms. Some municipalities may offer additional local senior exemptions - check with your local assessor.

Q: How often are properties revalued in York County? A: Maine requires municipalities to maintain assessments at current market value, with most towns conducting revaluations every 5-10 years. Some municipalities perform annual updates while others do comprehensive revaluations less frequently.

Q: What happens if I pay my property taxes late? A: Late payments incur interest charges, typically 7-9% annually starting the day after the due date. Municipalities may place liens on properties with unpaid taxes and eventually foreclose for non-payment.

Q: Can I pay my property taxes online? A: Most York County municipalities offer online payment options through their websites or third-party services. Check your municipality's website or tax bill for online payment information and any associated convenience fees.
