July Property Tax Deadlines by State: What's Due This Month
TL;DR
July brings important deadlines in Washington (July 1 Board of Equalization petitions), Missouri (Board of Equalization meetings), Connecticut (July 1 tax payment), Michigan (July 1 summer tax), and West Virginia (assessment notices arrive). California assessment notices also begin arriving this month. July is quieter than spring, but if you are in one of these states, your window is open now and may close quickly.
July Appeal Deadlines
| State | Deadline | Where to File |
|---|---|---|
| Washington | July 1 | County Board of Equalization |
| Missouri | Board of Equalization meets (typically July) | County Board of Equalization |
| Colorado | County Board of Equalization (if assessor denied appeal) | County board (typically early July) |
Washington - July 1
Washington homeowners must file petitions with the county Board of Equalization by July 1. Assessment notices arrive February through April, so you have had several months to prepare. If you have been putting it off, this is your last chance.
Washington does not have a state income tax, which means property taxes carry a heavier burden for funding local services. The average effective rate is around 0.84%, but it varies significantly by county. An overassessment in Washington translates directly into overpayment with no income tax deduction to offset it.
Missouri - Board of Equalization (July)
Missouri's county Boards of Equalization meet during July. Assessment notices arrive in June. Missouri reassesses residential property every odd-numbered year, so 2025 values carry forward into 2026. If your value jumped during the last reassessment, this is your window to protest.
Missouri assesses residential property at 19% of market value. To find the implied market value, divide your assessed value by 0.19. If that number is higher than what your home would sell for, you have grounds for a protest.

| State | What Arrives | Appeal Deadline |

| California | Informal notices of assessed value (formal notices in August) | September 15 - November 30 |
| West Virginia | Assessment notices | February 1 - March 1 (next year) |
| Utah | Assessment notices begin arriving | September 15 |
July Payment Deadlines
| State | What Is Due | Date | Notes |
|---|---|---|---|
| Connecticut | Tax payment | July 1 | Second installment due January 1 |
| Michigan | Summer tax | July 1 (varies by municipality) | Winter tax due December 1 |
What to Do in July
If Your Deadline Is This Month
Washington and Missouri homeowners: your window is closing. File now.
- Complete the appeal or protest form.
- Attach comparable sales showing your assessed market value is too high.
- Include photos of any condition issues.
- Submit before the deadline. Do not wait until July 1 if your deadline is July 1. File today.
If You Are in California
California's informal notices of assessed value start arriving in July. The formal notice follows in August. California is unique because of Proposition 13, which limits annual assessment increases to 2% unless the property changes hands or new construction occurs.
If your assessment increased by more than 2% and you did not buy the property or make improvements, the assessor may have made an error. Full California appeal guide.
The Assessment Appeals Board filing window runs from September 15 to November 30, so you have time to prepare. But start now. Gathering comps, checking property details, and building your case takes time.
If Your Spring Deadline Passed
July is a good time to regroup if you missed your spring appeal deadline. Here is what to do:
- Mark next year's deadline on your calendar now
- Start a file of comparable sales in your neighborhood
- Document condition issues while they are current
- Sign up for Annual Monitor ($49/year) for deadline reminders and updated comps
Mid-Year Assessment Check
July is the halfway point of the year. Even if you do not have a deadline this month, it is a good time to:
- Review your property record. Check for errors that may have been introduced or not yet corrected.
- Monitor your neighborhood. Track recent sales and compare them to your assessed value.
- Check your escrow. If your lender handles your property tax payments, review the escrow analysis for accuracy.
- Verify exemptions. Make sure all exemptions you qualify for are still applied to your account.
Looking Ahead: August and September
The fall appeal season is approaching for several states:
- Florida: TRIM notices arrive in August. Appeal within 25 days.
- California: Formal Assessment Appeals Board filing opens September 15.
- Louisiana: Assessment rolls open August-September.
- Utah: Board of Equalization deadline is September 15.
- Pennsylvania: Many counties have August-September appeal deadlines.
If you are in one of these states, use July to prepare your evidence and be ready to file the moment the window opens.
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.
