Property Tax Appeals in Miami-Dade County, Florida
Miami-Dade owners who disagree with a 2026 value, classification, exemption, or portability determination may petition the Value Adjustment Board. The Clerk published September 18, 2026 as the 2026 valuation-petition deadline, which has passed, and lists a $15 fee for each folio, subject to statutory exceptions. The Clerk's page describes an informal conference with the Property Appraiser's Office as a separate opportunity from a VAB petition, and Form DR-486 states that the conference does not change the filing due date. FairPath's owner-guided evidence packet remains available year-round to assemble official folio facts, owner-selected sales, and condition documents. The owner must select the petition type, verify the printed deadline, pay the fee, sign, file, and satisfy evidence-exchange requirements.
Assessment context: Miami-Dade valuation work should begin with the folio record, property card, land and building details, exemptions, classifications, sales, and TRIM notice. Waterfront access, flood and wind exposure, condominium governance, building recertification, special assessments, lease restrictions, unpermitted improvements, and neighborhood boundaries can distinguish nearby properties. Florida's just-value question is separate from Save Our Homes limitations and exemption eligibility; a reduced market value does not always reduce taxable value by the same amount. Compare the correct value column and valuation date. Homestead portability, agricultural classification, and exemption denials use distinct petition questions, so evidence prepared for a market-value dispute should not be relabeled as another claim.
Filing process: The Clerk's VAB page and local procedures describe the filing route; the 2026 filing deadline of September 18 has passed. The Clerk's page states that filing means received by the Clerk's office and that petitions postmarked before but received after the deadline are identified as filed late. The Board appoints special magistrates and provides hearing notices after processing. The Clerk's page describes a mandatory evidence exchange with the Property Appraiser at least 15 days before the hearing and a separate evidence upload to the Clerk's AXIA system by 9:00 am the day before the hearing. It also states that, by statute, contesting a valuation before the Board requires payment of all non-ad valorem assessments and at least 75 percent of the ad valorem taxes before the taxes become delinquent. The Clerk's page treats an informal conference with the Property Appraiser's Office as a step separate from a VAB petition.
Evidence to review: For just value, use arm's-length sales before the January 1 valuation date from the same competitive segment and explain adjustments for waterfront, flood zone, view, floor, unit line, living area, lot, age, renovation, parking, condition, and restrictions. Add photographs, inspection reports, engineering or recertification records, repair bids, association documents, permits, and maps when they affect market reaction. For classification or exemption issues, provide the ownership, occupancy, use, income, or application records required for that issue. Do not rely on tax amount or percentage increase alone. A folio-specific comparison table and a short reconciliation from evidence to requested value create a record the magistrate can follow.
Current deadline guidance: Closed: September 18, 2026. Miami-Dade County's official 2026 VAB portal lists September 18, 2026 as the petition deadline; that date has passed. The Clerk's VAB page states the general rule as no later than 25 days after the Property Appraiser mails the Notice of Proposed Property Taxes (TRIM notice), which it says is usually mailed the last week of August, and lists September 18, 2026 as the statutory deadline for the 2026 tax year.
Miami-Dade's 2026 valuation-petition deadline was September 18, 25 days after the annual TRIM mailing, and has passed.
The Clerk lists a fifteen dollar filing fee per folio and separate petition categories for value and eligibility disputes.
Waterfront, flood and wind exposure, condominium recertification, and association restrictions can materially affect comparable selection.
The Clerk's local procedures govern receipt, evidence exchange, hearing format, and rescheduling.
