How Property Tax Works

Property taxes in Cortland County, New York, are administered by individual municipalities and serve as the primary funding source for local government services, school districts, and county operations. The county consists of one city (City of Cortland) and nine towns, each with varying tax rates and assessment practices. Property owners pay combined taxes that typically include county taxes, town or city taxes, school district taxes, and any applicable special district levies such as fire protection or library districts.

Effective tax rates in Cortland County generally range from 2.5% to 4.0% of market value, though actual rates vary significantly by location within the county due to different municipal tax levies and special taxing districts. The county's 2025 tax rate is $11.9760 per $1,000 of assessed value at the county level, but property owners will see additional charges from their local municipality and school district. Assessment practices also vary by municipality, with different equalization rates applied across jurisdictions - for example, the City of Cortland has a 97.00% equalization rate while the Town of Cortlandville has a 63.00% rate.

Supplemental Tax Bills

Supplemental taxes in Cortland County are additional property tax assessments that occur when there are changes to a property's assessed value during the tax year. The most common triggers include new construction, property improvements that increase value, ownership transfers that result in reassessment, or corrections to assessment errors discovered after the regular tax roll is finalized.

When supplemental taxes are levied, they are calculated based on the difference between the old and new assessed values, multiplied by the applicable tax rate, and prorated for the portion of the tax year remaining. For example, if a property improvement increases the assessed value by $50,000 in July (halfway through the tax year), and the total tax rate is $30 per $1,000 assessed value, the supplemental tax would be approximately $750 ($50,000 ÷ 1,000 × $30 × 0.5 years).

Escrow & Property Taxes

Most mortgage lenders in Cortland County require property tax escrow accounts for borrowers with less than 20% down payment or upon borrower request. The lender collects monthly payments equal to 1/12th of the estimated annual property tax bill along with the mortgage payment. These funds are held in a non-interest-bearing escrow account and used to pay property taxes when due.

Lenders typically conduct annual escrow analyses to ensure adequate funds are collected, comparing actual tax payments to estimated amounts. If taxes increase, monthly escrow payments may rise accordingly. Property owners should verify that their lender has current tax information and is paying the correct amounts to the appropriate tax collector. Given the varying due dates across Cortland County municipalities (county/town taxes in January, some village taxes in March, others by April 30), borrowers should confirm their lender is aware of all applicable payment schedules.

Homeowners without escrow accounts are responsible for making direct payments to their municipal tax collector according to local due dates. Late payments typically incur penalties and interest charges as established by each municipality.

Frequently Asked Questions

Q: When are property taxes due in Cortland County for FY 2025? A: Due dates vary by municipality. County and town taxes are generally due in January, Village of Homer taxes are due in March, and some jurisdictions like the Town of Cortlandville have deadlines by April 30. Check with your specific municipal tax collector for exact dates.

Q: What tax credits are available and do I need to apply? A: The primary tax credit is the STAR program, which provides school tax relief for owner-occupied primary residences. Basic STAR and Enhanced STAR (for seniors with income limits) both require application and are NOT automatic. The deadline to apply for all exemptions and credits is May 1st each year.

Q: How does the STAR program work? A: STAR is a tax credit that reduces school property taxes only, not an exemption from assessed value. Basic STAR provides a standard reduction in school taxes, while Enhanced STAR provides larger reductions for senior citizens meeting income requirements. Both require annual application by May 1st.

Q: What other exemptions might I qualify for? A: New York offers Senior Citizens Exemptions and Veterans Exemptions that may reduce assessed value for qualifying property owners. These require separate applications with specific documentation and must be filed by the May 1st deadline. Contact your local assessor's office for eligibility requirements.

Q: How often are properties reassessed in Cortland County? A: Assessment schedules vary by municipality within Cortland County. Some conduct annual updates while others may reassess every few years. Each municipality maintains its own assessment roll with different equalization rates applied by New York State.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed with your local Board of Assessment Review, typically during a brief filing period in late spring/early summer. Contact your municipal assessor's office for specific deadlines and required forms. Appeals must demonstrate that your assessment is unequal, unlawful, or excessive.

Q: What are the penalties for late payment? A: Late payment penalties vary by municipality but typically include interest charges and fees. Some municipalities may also impose liens for significantly delinquent taxes. Contact your local tax collector for specific penalty structures.

Q: Can I pay my property taxes online? A: Online payment availability varies by municipality in Cortland County. Many local tax collectors now offer online payment options, but you should verify with your specific municipality's tax collector office for available payment methods and any associated processing fees.

Q: Why do tax rates vary so much within Cortland County? A: Tax rates vary due to different municipal service levels, school district funding needs, special district assessments (fire, library, water/sewer), and varying assessment practices. Each municipality sets its own tax levy, and properties may be subject to multiple overlapping taxing jurisdictions.

Q: What is the mortgage recording tax and when do I pay it? A: Cortland County imposes an additional mortgage recording tax of $0.25 for each $100 secured by a mortgage. This is typically paid at closing when obtaining a new mortgage or refinancing, separate from ongoing property taxes.
