If you own property in Central Ohio, 2026 brings significant changes to property tax deadlines. Franklin County has shifted its entire payment schedule, while Delaware County maintains its traditional dates. This isn't just about calendar changes—it affects cash flow, escrow calculations, and penalty risks.
Understanding these deadlines is crucial. Ohio's property tax system operates on an "arrears" basis, meaning you're paying for last year's taxes. The 2026 bills cover Tax Year 2025. With potential penalties hitting 10% immediately after deadlines, getting these dates wrong is expensive.
Critical 2026 Dates at a Glance
- Franklin County First Half: March 2, 2026 (not February 28)
- Delaware County First Half: February 10, 2026
- Franklin County Second Half: Likely July 20, 2026 (pending HB 186)
- Delaware County Second Half: July 10, 2026
The 2026 Deadline Shift Explained
2026 isn't just another tax year. It's a transition between valuation cycles. The 2023 Sexennial Reappraisal saw historic value increases—41% in Franklin County, 35% in Delaware. Now, the 2026 Triennial Update looms, potentially cementing post-pandemic gains into your tax base.
The payment schedule divergence creates compliance challenges. If you own properties in both counties, you need separate payment strategies. Mortgage servicers must update escrow algorithms. Property managers must adjust cash flow planning.
Why Dates Changed
Franklin County's shift to March 2 addresses operational bottlenecks. The Treasurer's office cited bill distribution challenges and alignment with state settlement processes. February 28 falls on a Saturday, triggering Ohio's weekend extension rule to March 2.
Delaware County's consistency reflects optimized internal processes. Their early February deadline helps fast-growing school districts access funds sooner. This matters for districts like Olentangy and Big Walnut facing enrollment surges.
County-by-County Breakdown: 2026 Deadlines
| County | First Half Due Date | Second Half Due Date | Key Notes |
|---|---|---|---|
| Franklin County | March 2, 2026 | July 20, 2026* | Date moved from January. *Pending HB 186 passage |
| Delaware County | February 10, 2026 | July 10, 2026 | Traditional schedule maintained. Bills online January 1 |
Franklin County: The March 2 Deadline
Mark March 2, 2026, on your calendar. This is the penalty-free deadline for first-half payments. The official date is February 28, but weekend extension rules push it to Monday, March 2. This 30-day extension from historical January dates offers liquidity benefits.
Second-half payments face legislative uncertainty. House Bill 186 could shift the deadline to July 20 or later. The Franklin County Treasurer will announce the exact date after Governor DeWine's review. This affects school district budgets ending June 30.
Delaware County: February 10 Stands Firm
Delaware County maintains its February 10 deadline. Bills appear online shortly after January 1, with physical copies mailed by January 15. This early schedule supports local government cash flows but demands prompt attention from property owners.
The second-half deadline is July 10, providing consistency for thousands of new homeowners entering Delaware's booming market. No legislative ambiguity here—just clear, predictable dates.

Payment Methods and Avoiding Penalties
Both counties use Point & Pay for digital transactions. Understanding fee structures saves money. Delaware County provides transparent breakdowns: credit cards cost 2.30% ($115 on $5,000), debit cards $3.95 flat, eChecks just $0.85.
Franklin County's system has search limitations during maintenance periods. Verify amounts early to avoid last-minute issues. Both counties offer escrow programs for homeowners without mortgages, smoothing cash flow with monthly payments.
The Penalty Reality
Ohio's penalty system is unforgiving. Miss the deadline by one day: 10% penalty. Pay within 10 days: penalty drops to 5%. After that, interest accrues monthly. Valid penalty remission requires documented emergencies or county errors—not forgetfulness.
Expert Tip: Set calendar reminders for February 5 (Delaware) and February 25 (Franklin). Verify payment confirmation immediately.
The 20-Mill Floor: Delaware's Hidden Tax Risk
Most Ohioans enjoy HB 920 protection—tax rates adjust downward as values rise. But the 20-mill floor changes everything. Once a school district hits this constitutional minimum, value increases translate directly to tax increases.
In Delaware County, three districts face this reality: Big Walnut Local, Buckeye Valley Local, and Delaware City Schools. Their residents felt the full 35% 2023 reappraisal impact. With the 2026 Triennial Update approaching, these homeowners should brace for more direct tax increases.
Franklin County districts generally remain above the floor, benefiting from HB 920's inflation shield. This creates a fairness debate as neighboring homeowners experience vastly different tax trajectories despite similar property appreciation.
New Construction Warning: The "Lag Trap"
Buying new construction in 2026? Beware the tax lag. Your initial tax bill reflects vacant land value—often $500 instead of the true $10,000+ for a completed home. Mortgage escrow calculations based on this underestimate create future shocks.
When auditors update records 12-18 months later, escrow shortages emerge. Monthly payments can double overnight to cover back taxes and new higher amounts. Ohio's omitted property laws allow five-year lookbacks, though without penalties.
New Construction Checklist
- Ask builders for projected tax estimates in writing
- Verify current tax record shows "land only" status
- Request lender escrow analysis using estimated completed value
- Monitor county auditor site for permit completion updates
- Budget for potential escrow shortage repayment
2026 Triennial Update: What's Next
While 2026 bills use 2023 values, auditors are already working on the 2026 Triennial Update. This statistical revaluation uses 2023-2025 sales data and affects Tax Year 2026 (payable in 2027).
Franklin County analyzes whether the market stabilized after 41% increases. Delaware County considers the "Intel Effect"—speculative demand from the semiconductor facility. Both counties will release tentative values in Fall 2026, with informal review opportunities.
Agricultural landowners face separate challenges. Current Agricultural Use Value (CAUV) program updates may increase soil values up to 50% due to strong crop prices and formula changes. This impacts operating costs for Delaware County's rural sectors.
Practical Resources and Next Steps
Both counties provide digital portals for bill lookup and payment. Franklin County: treasurer.franklincountyohio.gov. Delaware County: treasurer.co.delaware.oh.us. Bookmark these and verify your parcel details early.
Appeals for 2025 values must be filed between January 1 and March 31, 2026, using DTE Form 1. Evidence matters—appraisals or closing statements, not subjective complaints. The 2026 Triennial Update informal reviews occur in October/November 2026.

Frequently Asked Questions
Why is Franklin County's deadline March 2 instead of February 28?
February 28, 2026 falls on a Saturday. Ohio law (ORC 1.14) extends deadlines falling on weekends to the next business day. So the enforceable, penalty-free date becomes Monday, March 2, 2026.
Can I get penalties waived if I forget to pay?
Only in specific circumstances. Form 23A allows penalty remission for non-receipt of bills (with proof of inquiry), medical emergencies within 60 days of deadline, or county errors. "Forgetting" or "lack of funds" doesn't qualify.
What's the cheapest way to pay my property taxes online?
eCheck payments cost just $0.85 in both counties. Credit cards charge 2.30% (expensive on large bills), debit cards $3.95 flat. For a $5,000 bill, eCheck saves $114.15 versus credit card.
I bought new construction in 2025. When will my taxes increase?
Typically 12-18 months after closing. The county auditor must complete the assessment update. Monitor the auditor's site and prepare for potential escrow shortages when the bill jumps from land-only to improved value.
What happens if House Bill 186 doesn't pass?
Franklin County's second-half deadline would likely revert to the traditional June 20 date. The Treasurer's office will announce the confirmed date after legislative resolution. Monitor official county communications.
How does the 20-mill floor affect me in Delaware County?
If you're in Big Walnut, Buckeye Valley, or Delaware City school districts, property value increases directly increase your taxes. Other districts have HB 920 protection that reduces rates as values rise, minimizing tax impacts.
Final Thoughts
The 2026 property tax year in Central Ohio demands proactive attention. Franklin County's shifted deadlines offer liquidity benefits but require calendar adjustments. Delaware County's consistency comes with early action requirements.
Beyond deadlines, understand your valuation context. The 2026 Triennial Update approaches, potentially locking in pandemic-era gains. New construction buyers must navigate the lag trap. Agricultural landowners face CAUV volatility.
Mark your calendars: February 10 for Delaware, March 2 for Franklin. Verify amounts early. Choose economical payment methods. Monitor valuation notices in Fall 2026. With these steps, you'll navigate 2026's property tax landscape confidently.
