How Property Tax Works

Genesee County, New York operates under a property tax system that funds essential local services including county operations, schools, towns, cities, and special districts. Property taxes are the primary revenue source for local governments, supporting services such as public safety, road maintenance, education, and community programs. The county follows New York State's Real Property Tax Law, with assessments based on market value and various exemptions and credits available to qualifying property owners.

For the 2025 levy year, Genesee County's base tax rate decreased to $7.57 per $1,000 of assessed value, down from $8.08 in the previous year - a reduction of approximately 6.31%. However, actual property tax bills vary significantly by location within the county due to additional levies from school districts, towns, cities, villages, and special taxing districts such as fire districts and library districts. The combined effective tax rate typically ranges from 2.5% to 3.5% of market value depending on your specific location and applicable districts.

Property owners should note that New York's taxable status date is March 1st, meaning property ownership and exemption eligibility are determined as of this date each year. Most exemptions and credits require annual application and are not automatically applied to your tax bill.

When Are Property Taxes Due?

Section 4

Supplemental Tax Bills

Supplemental taxes in Genesee County are additional property tax assessments that occur when there are changes to property ownership, value, or use after the March 1st taxable status date. Under New York State Real Property Tax Law Sections 554 and 556, the County Treasurer has authority to bill and collect these supplemental charges.

Common triggers for supplemental taxes include: new construction completed after March 1st, property improvements that increase assessed value, changes in exemption status, or correction of assessment errors. The supplemental tax is calculated by applying the current year's tax rate to the difference between the original assessment and the new assessment, prorated for the portion of the tax year remaining.

Example: If you complete a $100,000 home addition in June that increases your assessed value by $80,000, and your total tax rate is $30 per $1,000 of assessed value, your supplemental tax would be approximately $1,600 (($80,000 ÷ 1,000) × $30) prorated for 7 months, resulting in a supplemental bill of about $933. Supplemental tax bills are typically issued within 60-90 days of the assessment change and have separate due dates from regular property tax bills.

Escrow & Property Taxes

Most mortgage lenders in Genesee County require property tax escrow accounts for loans with less than 20% down payment. Your lender collects monthly payments equal to 1/12th of your estimated annual property tax bill, plus a cushion typically equal to 2-3 months of payments as required by federal law.

Property tax payments in Genesee County are due January 31st to avoid penalties. Lenders typically make payments in late January using funds collected throughout the year. After payment, your lender should provide documentation showing the tax payment was made on your behalf. You'll receive an annual escrow analysis statement showing the previous year's activity and any adjustments needed for the coming year.

If your property taxes increase due to reassessment or rate changes, your lender will adjust your monthly escrow payment accordingly. Conversely, if taxes decrease, you may receive a refund of excess escrow funds. Property owners should verify that their lender has made timely tax payments and contact the County Treasurer's office if there are any discrepancies. Remember that even with escrow accounts, you remain ultimately responsible for ensuring property taxes are paid on time.

Frequently Asked Questions

Q: When are property taxes due in Genesee County for the 2025 tax year? A: Town and county property taxes must be postmarked on or before January 31st to avoid penalties. Payments made February 1st through February 28th incur a 1% penalty, with additional penalties accruing monthly thereafter.

Q: What tax credits are available and do they require application? A: The primary tax credit is the STAR (School Tax Relief) program, which provides exemptions on school taxes only. STAR Basic provides up to $30,000 exemption and requires annual application. Enhanced STAR for seniors 65+ provides larger exemptions. Veterans exemptions, senior citizen exemptions, and disability exemptions are also available but ALL require application by March 1st.

Q: How does the STAR exemption work? A: STAR is actually an exemption that reduces your assessed value for school tax purposes only. It does NOT reduce your market value or county/town taxes. You must apply annually, and the exemption amount is deducted from your assessed value before school taxes are calculated.

Q: When are properties reassessed in Genesee County? A: Assessment practices vary by municipality within Genesee County. Contact your local assessor's office for specific reassessment schedules. The taxable status date for all properties is March 1st annually, meaning ownership and exemptions are determined as of that date.

Q: How do I appeal my property assessment? A: Assessment appeals must typically be filed with your local Board of Assessment Review by "Grievance Day" (usually the fourth Tuesday in May). Contact your municipal assessor's office for specific deadlines and required forms. You'll need evidence supporting your claim that the assessment exceeds market value.

Q: Can I pay property taxes online? A: Contact the Genesee County Treasurer's office for current online payment options and accepted methods. Many municipalities offer online payment systems, but availability varies by location within the county.

Q: What happens if I pay property taxes late? A: Late payments incur a 1% penalty starting February 1st, with additional penalties and interest accruing monthly. Prolonged non-payment can eventually result in tax lien proceedings and potential foreclosure.

Q: Do special districts add to my tax bill? A: Yes, special districts such as fire districts, library districts, water districts, and lighting districts impose additional taxes that appear on your property tax bill. These rates vary significantly based on your property's location and which districts serve your area.

Q: How do I apply for property tax exemptions? A: Applications must be filed with your local assessor's office on or before the March 1st taxable status date. Visit your municipal assessor's office or the New York State Department of Taxation and Finance website for specific application forms and eligibility requirements.

Q: What if I disagree with a supplemental tax assessment? A: Supplemental assessments can be challenged through the same appeal process as regular assessments. Contact your local assessor's office immediately if you receive a supplemental tax bill you believe is incorrect, as appeal deadlines are strictly enforced.
