Key Takeaways:
Property tax appeal deadlines by state in 2026 range from a fixed calendar date to a rolling window that starts the day your notice arrives. Texas gives you until May 15. Georgia and Maryland give you about 45 days from your notice date. New Jersey's earliest filers are due January 15 β three months before the rest of the state. Miss any of these and you wait a full year for the next chance to lower your bill.
TL;DR
- Texas property tax appeal deadline is fixed at May 15, 2026 β the most predictable window of the six states TaxDrop covers.
- New Jersey's Burlington, Gloucester and Monmouth counties file by January 15, 2026, while the rest of the state has until April 1.
- Georgia and Maryland set deadlines relative to your notice date, roughly 45 days out, not a fixed calendar day.
- California and Florida deadlines shift with the county assessor's calendar and the TRIM notice mailing date β no single statewide date applies.
- Miss your property tax appeal deadline in any state and the assessment stands for the full tax year.
Why this matters
Between 30% and 60% of properties are over-assessed in a given year, and only about 5% of owners ever file an appeal. Deadlines are a big reason why: the window is short, it's easy to miss, and every state calls it something different.
TaxDrop tracks property tax appeal deadlines across Texas, California, Georgia, Florida, New Jersey, and Maryland because a missed date costs you the entire tax year, not just a delay. TaxDrop runs a free assessment check that takes under two minutes so you know where you stand before the clock runs out.
The six states split into three deadline patterns: a fixed calendar date (Texas, and New Jersey outside three counties), a window that starts when your notice is mailed (Georgia, Maryland, Florida), and a schedule set entirely by the local assessor (California). Knowing which bucket your state falls into tells you what to watch for in the mail.
Every state's deadline falls into one of three patterns β knowing which one applies tells you what to watch for.
Property tax appeal deadlines by state (2026)
Texas
- What it's called: Protest
- Who hears it: Appraisal District (CAD)
- Your notice: Notice of Appraised Value
- Deadline: May 15
California
- What it's called: Appeal
- Who hears it: Assessor's Office
- Your notice: Assessment Notice
- Deadline: Varies by county
Georgia
- What it's called: Appeal
- Who hears it: Board of Tax Assessors
- Your notice: Annual Notice of Assessment
- Deadline: ~45 days from notice
Florida

- Your notice: TRIM notice
- Deadline: ~25 days from TRIM
New Jersey
- What it's called: Appeal
- Who hears it: County Board of Taxation
- Your notice: β
- Deadline: April 1 (Jan 15 in Burlington, Gloucester, Monmouth)
Maryland
- What it's called: Appeal
- Who hears it: SDAT / Supervisor of Assessments
- Your notice: Reassessment notice
- Deadline: ~45 days (Jan 1 off-cycle)
Florida has the shortest fixed clock on this list at roughly 25 days from the TRIM notice mailing. New Jersey's Burlington, Gloucester and Monmouth counties file earliest of anyone at January 15, a full 15 months ahead of California owners whose county might not mail a notice until mid-year. Texas has the longest lead time of any fixed-date state β owners typically know the May 15 deadline months in advance because the CAD mails notices in April.
Methodology: Deadlines reflect published state statutes and county board calendars current as of 2026. One limitation: California and Florida set exact dates at the county level, so the table shows the statutory reference point, not every county's specific mailing date β check your assessor's notice for the exact day.
New Jersey's deadline comes with a warning
Filing in New Jersey isn't a one-way bet. New Jersey decides appeals on the Chapter 123 ratio test, not straight market value, and the county board is required by statute to raise your assessment if you fall below the common level range. New Jersey is also the only state on this list that charges an upfront filing fee β $5 to $150, non-refundable β so a generic appeal without a strong case can cost you money and raise your bill. Comparable assessments aren't admissible in New Jersey; you need sales data. Owners weighing a New Jersey property tax appeal should confirm which county deadline applies before filing anything.
Appeal season by state
Deadlines tell you the last date to file. Season tells you when most owners actually get their notice and start the process.
Texas
- Peak filing season: March β May
Georgia
- Peak filing season: April β June
California
- Peak filing season: July β November
Florida
- Peak filing season: August β September
New Jersey
- Peak filing season: January β April
Maryland
- Peak filing season: December β February
California's five-month window is the longest on this list, giving owners the most flexibility to gather evidence before filing. Maryland's window looks short by comparison, but the bigger catch is that Maryland reassesses only one-third of the state each year β so roughly two out of three Maryland owners don't have a live appeal window in any given season at all.
How to use these benchmarks
- Mark the deadline, not the season. Seasons tell you when notices typically arrive; the deadline is the date that actually matters and it doesn't move for you.
- Watch the mail in notice-triggered states. Georgia, Maryland, and Florida deadlines start counting the day your notice is dated, not the day you open the envelope.
- Confirm your county in California and Florida. Statewide reference dates don't apply county by county β your assessor's notice has the real date.
- File early in New Jersey, and only with sales evidence. Check whether you're in Burlington, Gloucester, or Monmouth before assuming the April 1 date applies to you.
- Track the assessment-to-filing timeline. TaxDrop's property assessment notice to filed appeal workflow walks through what happens between the notice landing in your mailbox and a filed case.

FAQ
What is the property tax appeal deadline for Texas in 2026?
Texas sets the protest deadline at May 15, 2026, or 30 days after your Notice of Appraised Value is mailed, whichever is later. The appraisal district mails notices in April, so most owners know the date months ahead.
When is the New Jersey property tax appeal deadline in 2026?
Most New Jersey municipalities require appeals by April 1, 2026. Burlington, Gloucester, and Monmouth counties file earlier, by January 15, 2026, because they use annual reassessment programs.
How long do I have to appeal my property taxes in Georgia?
Georgia gives you roughly 45 days from the date on your Annual Notice of Assessment, not a fixed calendar date. The Board of Tax Assessors hears the appeal.
What is the Maryland property tax appeal deadline?
Maryland gives owners about 45 days from their reassessment notice to appeal, plus a January 1 off-cycle window. SDAT reassesses only one-third of the state each year, so most owners only have a live window every three years.
When does the Florida property tax appeal window open?
Florida's window opens when the TRIM notice mails, and you generally have about 25 days from that date to petition the Value Adjustment Board. There is no fixed calendar deadline statewide.
Does California have one statewide property tax appeal deadline?
No. California deadlines vary by county because each Assessor's Office sets its own Assessment Notice and appeal calendar. Check your county assessor's notice for the exact date.
What happens if I miss my property tax appeal deadline?
Missing the deadline in any of the six states TaxDrop serves means the current assessment stands for the full tax year. You wait until the next assessment cycle to appeal again.
Can filing a property tax appeal in New Jersey raise my assessment?
Yes. New Jersey decides appeals using the Chapter 123 ratio test, and the county board must raise your assessment by statute if it falls below the common level range. This risk doesn't exist in Texas, California, Georgia, Florida, or Maryland.
One last thing
Maryland's deadline looks routine on paper, but the real story is the reassessment cycle: only a third of the state gets a new assessment notice each year, so most Maryland owners don't have a live appeal window in 2026 at all. Check your specific reassessment year before assuming the 45-day clock applies to you this season.
