How Property Tax Works

Delaware County, New York operates under the state's property tax system, which funds essential local services including schools, county operations, municipal services, and special districts. Property taxes in Delaware County are levied by multiple jurisdictions - the county, local municipalities (towns and villages), school districts, and various special districts such as fire districts and library districts. This multi-layered approach means that property owners receive separate tax bills from different taxing authorities throughout the year.

The effective property tax rates in Delaware County vary significantly depending on your specific location within the county, as each municipality and school district sets its own tax rate. While New York State has a base assessment rate around 1.4%, actual rates in Delaware County can differ substantially due to local budget needs and special district assessments. Property owners should expect their total annual property tax burden to come from multiple separate bills rather than a single consolidated statement.

The assessment and collection process varies by municipality within Delaware County, with different towns and villages managing their own assessment rolls and collection schedules. Unlike some states, New York does not impose a statewide cap on property tax assessments, though the STAR program provides school tax relief for eligible homeowners who apply for the benefit.

Note: The 2025 property tax rates for Delaware County are not yet finalized. Property owners should check with their specific town, village, and school district offices for current levy year rates. Delaware County follows New York's fiscal year calendar, with most municipalities operating on a calendar year basis (January 1 - December 31) for property tax purposes.

Tax rates vary significantly across Delaware County's 19 towns and multiple villages due to different local budget requirements and special taxing districts. Properties may be subject to additional assessments depending on their location within special service areas such as fire protection districts, library districts, or improvement districts.

When Are Property Taxes Due?

Pro tip: If you pay through mortgage escrow, your lender splits these payments across your monthly mortgage. If you pay directly, set calendar reminders to avoid late penalties.

Supplemental Tax Bills

Supplemental property taxes in Delaware County are additional tax assessments that occur when there are changes to a property's assessed value during the tax year. The most common triggers for supplemental taxes include new construction completion, property improvements that increase assessed value, subdivision of property, or corrections to the assessment roll discovered after the initial tax bills were issued.

When a supplemental assessment is issued, the additional tax is calculated by applying the current tax rates to the increase in assessed value, prorated for the portion of the tax year remaining. For example, if a $50,000 addition to your home is completed and assessed in July, you would owe supplemental taxes on that additional assessed value for the remaining six months of the tax year.

Property owners receive a separate supplemental tax bill that includes details about the reason for the additional assessment, the effective date, and the calculation method used. These supplemental taxes have their own due dates, typically 30 days from the bill date, and are separate from your regular property tax obligations. The supplemental amount will also be incorporated into the following year's regular tax assessment.

Escrow & Property Taxes

Most mortgage lenders in Delaware County require borrowers to maintain an escrow account for property taxes, especially when the loan-to-value ratio exceeds 80%. Your lender collects monthly escrow payments along with your mortgage payment and holds these funds to pay your property taxes when they become due. The monthly escrow amount is calculated by estimating your annual property tax liability and dividing by 12, often with a small cushion to account for potential increases.

Due to Delaware County's multiple taxing jurisdictions, your lender must track and pay several different tax bills throughout the year - typically school taxes in the fall and municipal/county taxes in January. Lenders are required to provide annual escrow statements showing all deposits, payments made on your behalf, and any account shortages or surpluses. If there's a shortage, you may need to increase your monthly payment or pay a lump sum; surpluses over $50 are typically refunded.

Property owners should verify that their lender has paid all tax bills correctly, as you remain ultimately responsible for ensuring taxes are paid even when using escrow. You can check payment status with each tax collector - your town/village clerk for municipal taxes and your school district business office for school taxes. If you pay off your mortgage or your loan-to-value drops significantly, you may be able to eliminate the escrow requirement and pay taxes directly.

Frequently Asked Questions

Q: When are property taxes due in Delaware County? A: Property taxes in Delaware County are generally due in January, with April 30th as the final deadline for unpaid taxes.

Contact your local town/village tax collector and school district for specific due dates.

Q: What tax credits are available and do I need to apply? A: The main tax credit available is the STAR program, which provides school tax relief. Basic STAR and Enhanced STAR (for seniors 65+) both require annual application and have income eligibility requirements. The 2025 STAR credit was up to $964 in some Delaware County towns. You must apply - these credits are not automatic.

Q: How does the Senior Citizens Exemption work? A: The Senior Citizens Exemption is available for property owners age 65 and older, reducing the assessed value of their property for tax calculation purposes. This is an exemption (reducing assessed value) rather than a credit (reducing tax bill). You must apply through your local assessor's office and meet income eligibility requirements.

Q: When are properties reassessed in Delaware County? A: Assessment schedules vary by municipality within Delaware County. Some towns conduct annual updates while others may reassess every few years. Contact your local assessor's office for your specific reassessment schedule and current assessment roll information.

Q: What are the penalties for late property tax payments? A: Late payment penalties vary by taxing jurisdiction within Delaware County. Generally, interest and penalties begin accruing after the due date, with rates typically ranging from 1-1.5% per month. Some jurisdictions may charge additional fees. Contact your tax collector for specific penalty structures.

Q: Can I pay property taxes online? A: Online payment options vary by municipality and school district within Delaware County. Many local tax collectors now offer online payment systems, but you'll need to check with each individual taxing authority as they maintain separate collection systems.

A: Assessment appeals in Delaware County must be filed with your local Board of Assessment Review (BAR) during the designated grievance period, typically in late spring/early summer. Contact your town assessor's office for specific deadlines and required forms. Appeals must be based on unequal assessment, excessive assessment, or unlawful assessment.

Q: Are veterans eligible for property tax benefits? A: Yes, qualifying veterans may be eligible for the Veterans Exemption, which reduces assessed value for property tax calculations. This includes exemptions for disabled veterans and veterans who served during wartime periods. Applications must be filed with your local assessor's office with required military documentation.

Q: Do I need to pay taxes on special district services? A: Yes, if your property is located within special districts such as fire districts, library districts, or improvement districts, you'll receive separate tax bills for these services. These are in addition to your regular county, town/village, and school taxes and have their own due dates and collection procedures.
