What Is Fiscal Year
A fiscal year is the 12-month period a taxing authority uses to budget, collect, and account for tax revenue. For most counties and municipalities, the fiscal year runs from July 1 to June 30, though some jurisdictions use the calendar year (January 1 to December 31) or other periods. Your property tax bill references the fiscal year in which taxes are levied and collected, which directly affects when assessments are locked in and when you can challenge them.
Why Fiscal Year Timing Matters for Appeals
The fiscal year determines the assessment date for your property. Most jurisdictions conduct valuations as of January 1 of the fiscal year, meaning market conditions and comparable sales from that specific date are used to establish your assessment. If your assessment was set in FY2025 (based on January 1, 2025 values), you cannot appeal based on comparable sales from June 2024 or October 2025 alone. The assessment ratio for your property class, typically ranging from 25% to 100% of market value depending on your state, applies to that fiscal year's valuation.
Understanding which fiscal year your assessment belongs to is critical for gathering the right evidence. If you miss the appeal deadline for a specific fiscal year, you must wait until the next assessment cycle, which could be 2-4 years away depending on your jurisdiction's revaluation schedule.
How Fiscal Year Affects Assessment and Appeals
- Assessment Date Lock: Your property is valued as of a specific date within the fiscal year, typically January 1. This date anchors all comparable sales analysis and appraisal methods used by the assessor's office.
- Comparable Sales Window: Most board of review hearings accept sales from 90 days before and after the assessment date. For January 1 assessments, this means October 3 through April 1 sales carry the most weight.
- Tax Bill Issuance: The Tax Bill is based on the fiscal year assessment. Your FY2025 bill reflects FY2025 values, even if issued in September or October.
- Appeal Deadlines: Most jurisdictions require appeals to be filed within 30-45 days of receiving your assessment notice or tax bill, placing the deadline firmly within the fiscal year the assessment applies to.
- Exemptions and Abatements: Property tax exemptions (senior, disabled, agricultural, industrial) are evaluated for each fiscal year separately. Changes to your property or exemption status in one fiscal year do not automatically carry to the next year.
Fiscal Year and Appraisal Methods
Assessors use three appraisal approaches to determine value as of the assessment date: the sales comparison approach (analyzing comparable properties), the cost approach (replacement cost minus depreciation), and the income approach (for rental properties). All three methods anchor to the fiscal year's assessment date. If your 2-year-old roof or recent kitchen renovation falls outside the fiscal year being appealed, it may be treated as a future improvement rather than current value. When presenting evidence to a board of review hearing, emphasize which fiscal year your repairs or improvements occurred in, as this directly affects whether they count toward reducing your assessment.
Common Questions
- If my property was assessed in FY2025 and I'm now in FY2026, can I still appeal the old assessment? No. Each fiscal year has its own appeal deadline, typically 30-45 days from notification. Once that window closes, you cannot appeal that year's assessment. You can only appeal the FY2026 assessment during its designated filing period.
- Do comparable sales from outside my fiscal year's assessment date count in a board of review hearing? Minimally. Sales within 90 days of the assessment date are most relevant. Sales from a different fiscal year can support trends but carry less weight than same-year comparables with similar property characteristics.
- How does the Tax Levy relate to the fiscal year? The tax levy is the total amount a municipality needs to raise in a specific fiscal year. Your assessment determines your share of that levy. A higher fiscal year levy can increase your tax bill even if your assessment stays the same.
