Key August Deadlines Explained
Florida - 25 Days After TRIM Notice
Florida's TRIM (Truth in Millage) notice arrives in August. This is the most compressed appeal window in the country: just 25 days from the date on the notice. That is barely three weeks to review, research, and file.
The TRIM notice shows:
- Your property's assessed value and taxable value
- Your proposed tax by each taxing authority
- What you paid last year for comparison
- Dates for public budget hearings
To appeal, file a petition with the Value Adjustment Board (VAB). The petition form is available from your county property appraiser's office or website. You will be scheduled for a hearing, typically in October-December.
Florida's homestead exemption (up to $50,000) and Save Our Homes cap (3% annual increase limit on assessed value for homesteaded properties) are already factored into the TRIM notice. If these are missing from your notice, contact the property appraiser immediately.
Pennsylvania - Varies by County
Pennsylvania does not have a statewide reassessment schedule. Each county sets its own timeline. Many counties have appeal deadlines in August or September. Some have not reassessed in decades.
Check with your county Board of Assessment Appeals for your specific deadline. Common deadlines include:
- Allegheny County (Pittsburgh): varies, typically March
- Philadelphia: October 7
- Chester, Delaware, Montgomery Counties: August 1

Arkansas - Third Monday in August
Arkansas counties hold equalization board hearings starting the third Monday in August. If you believe your assessment is too high, you must attend or file before this hearing. Assessment notices arrive in March-April, so you have had months to prepare.

What to Do in August
If You Are in Florida
This is your most critical month. When the TRIM notice arrives:
- Open it immediately. Note the date on the notice. Count 25 days. That is your deadline.
- Check your exemptions. Is the homestead exemption applied? Save Our Homes cap?
- Compare the assessed value to market. If the assessed value (after exemptions) is higher than what your home would sell for, you have grounds to appeal.
- Pull comps. 3-5 recent sales of similar homes nearby.
- File the VAB petition. Available from your county property appraiser's website.
With only 25 days, you cannot afford to wait. Start the day the notice arrives.
If You Are in California
California's formal assessment notice arrives in August. Your appeal window does not open until September 15, so use August to prepare:
- Review the notice and check property details
- Research comparable sales from the last 12 months
- Document any condition issues
- Get an independent appraisal if the value seems significantly off
Be ready to file on September 15 when the window opens. Full California guide.
If You Are in Louisiana
Louisiana assessment rolls open for public inspection in August-September. You have 15 days after the rolls open to file a protest. Check with your parish assessor for the exact dates.
The Florida Challenge
Florida's 25-day window is the tightest in the country. Here is how to manage it:
- Pre-prepare. Before the notice arrives, pull comps and check your property record online.
- File the petition, then prepare your evidence. Filing the petition preserves your right to a hearing. You can gather evidence after filing.
- Budget for hearing preparation. VAB hearings happen October-December. Use the months between filing and the hearing to build a thorough case.
Your Next Steps
Put this information to work this week:
- Review your assessment notice. Check every detail: assessed value, property characteristics, square footage, lot size. Errors are more common than you think and they directly inflate your tax bill.
- Pull comparable sales. Find 3 to 5 similar properties near you that sold recently for less than your assessed value. This is the strongest evidence for any appeal.
- Check your exemption status. Contact your county assessor to confirm which exemptions are on file for your property. You may qualify for programs you have not applied for.
- Set a deadline reminder. Find your appeal deadline and put it on your calendar with a 2-week advance warning. Missing it costs you a full year of potential savings.
Staying Ahead of the Calendar
Property tax deadlines are spread throughout the year, and it is easy to lose track. The homeowners who save the most money are the ones who treat their assessment notice as a trigger for action, not something to file away and forget.
When your notice arrives, open it the same day. Check the assessed value against what you believe your home is worth. If the number looks too high, start gathering comparable sales immediately. Do not wait until the week before the deadline. The best appeals are built over weeks, not hours.
If you are in a state with quarterly tax payments, set reminders for each installment date. Late payment penalties add up fast and are entirely avoidable with basic calendar management.
