Florida's Commercial Property Tax Appeal Process Has a New Evidence Clock
For a Florida commercial property owner, filing a Value Adjustment Board (VAB) petition is only the first procedural step. The hearing is where the valuation record is tested: the property record card, income and expense information, comparable sales, photographs, leases, and other evidence are presented and weighed.
As of the 2026 cycle, Florida's evidence-exchange rules are different from the rules many owners used in prior years. A 2025 statutory change requires the property appraiser to provide hearing evidence to a petitioner at least 15 days before the hearing and removes the prior requirement that the owner first make a written request. The Florida Department of Revenue describes the change in its 2025 legislative changes notice.
That change does not create a guaranteed reduction, eliminate the filing deadline, or turn a VAB petition into a reappraisal. It does give owners a clearer opportunity to see the county's case before the hearing and organize a focused response.
What changed for 2026 hearings?
Florida Statutes section 194.011 still allows a taxpayer to request an informal conference with the property appraiser and to file a valuation petition with the county's VAB clerk. For valuation issues, the statutory filing window is generally on or before the 25th day after the property appraiser mails the notice of proposed property taxes. Read the current text of section 194.011 and the county's instructions before relying on that general rule.
The important change comes later. For a hearing on or after September 1, 2025, the Florida Department of Revenue's taxpayer guide says:
- The petitioner must provide the property appraiser, at least 15 days before the hearing, a list of evidence, copies of documentation to be considered, and a summary of witness evidence.
- The property appraiser must provide its evidence to the petitioner at least 15 days before the hearing.
- The petitioner no longer needs to ask in writing for the property appraiser's evidence.
The Department's Taxpayer Guide on Petitions to the Value Adjustment Board also explains that a petitioner may ask the clerk to reschedule if the property appraiser does not timely provide its materials. The guide notes that the board or special magistrate may still accept late evidence, but owners should not build their strategy around that possibility.
What should a commercial owner exchange?
The statute sets a procedural floor, not a complete valuation checklist. The right package depends on the property and the valuation issue. A useful commercial file often includes:
The county record. Download the property record card and verify land area, building area, quality, age, construction class, condition, parcel configuration, use code, and any listed improvements. A factual error can be more persuasive than a disagreement with the county's conclusion.
Income and expense support. For an income-producing property, prepare rent rolls, executed leases, operating statements, vacancy information, reimbursements, concessions, capital expenditures, and a clear explanation of unusual items. Separate property-level performance from ownership-level or financing information that does not reflect the real estate's value.
Market evidence. Use comparable sales, leases, listings, or other market data that match the property's location, size, use, age, condition, and income profile. Explain adjustments rather than presenting a list of distant or dissimilar transactions.
Condition and obsolescence. Document deferred maintenance, functional limitations, access issues, flood or storm impacts, environmental constraints, tenant-related physical impacts, or other conditions that a mass appraisal record may miss. Photographs, contractor estimates, inspection reports, and repair histories can help connect the condition to value.
A short valuation explanation. State the requested just value and show how the evidence gets there. A board is more likely to follow a transparent calculation than a conclusion unsupported by a workpaper.
For a broader evidence framework, see Castellan's guide to what counts as evidence in a commercial property tax appeal. Florida's own rules require the exchange of the evidence the parties intend to present; they do not require the owner to submit every document in the company's files.
Why timing matters more than the new rule suggests
The 15-day exchange date is tied to the hearing date, not the date the TRIM notice arrives. That creates a second calendar problem. The VAB clerk may schedule hearings weeks after the petition deadline, and different counties publish different instructions, portals, forms, and hearing schedules.
Start with the notice and the county's VAB page. The Florida Department of Revenue forms page provides the statewide DR-486 petition form and related materials, but the clerk's local filing instructions still matter. Keep proof of submission, confirm that attachments uploaded correctly, and do not assume that an informal conference pauses or extends the statutory petition deadline.
A practical calendar for a portfolio owner is:
- When the TRIM notice arrives: record the mailing date printed or reflected by the county, download the property record card, and identify the valuation issue.
- Before filing: request an informal conference if useful, but prepare the petition in parallel so the 25-day window is not lost.
- After filing: monitor the clerk's hearing notice and calculate the 15-day evidence date from the actual hearing date.
- At least 15 days before the hearing: send the evidence list, documents, and witness summary to the property appraiser using the method the clerk accepts.
- Before the hearing: compare the county's production with your record, identify factual disagreements, and prepare a concise presentation.
What the new evidence exchange does not do
The change improves access to the county's hearing materials, but it does not shift every legal burden or require the VAB to accept the owner's value. Florida law still requires the property appraiser's assessment to be evaluated under the statutory valuation framework, including the factors in section 193.011. Those factors include present cash value, highest and best use, location, size, cost and replacement value, condition, income, and net sale proceeds. See section 193.011, Florida Statutes.
Nor does a lower market estimate automatically translate into a lower tax bill. Florida's assessment roll separates just value, assessed value, and taxable value, and the final bill also depends on millage and exemptions. Owners comparing bills should first identify which value is disputed; market value and assessed value are not the same number.
Finally, statewide procedure does not mean identical county practice. Filing portals, accepted formats, hearing logistics, local forms, and the date printed on the TRIM notice can differ. A general article cannot supply a county's operative deadline.
A better 2026 preparation standard
The best use of the new rule is not to wait for the county's evidence. Build the file before filing: verify the record card, preserve income and expense support, select comparable evidence, document physical conditions, and articulate the valuation conclusion. Then use the county's production to test assumptions and fill gaps.
If the assessment appears unsupported, Castellan can provide a free analysis of the property, the available evidence, and the applicable county process. An analysis is not a promise of a reduction; it is a way to decide whether further work is justified before the relevant deadline.
