PROPERTY TAX APPEAL TIMELINE

How Long Does a Property Tax Appeal Take?

Timelines vary by state, jurisdiction, and case complexity. Here's what commercial property owners in Michigan, Indiana, Ohio, Pennsylvania, Wisconsin, and Georgia should realistically expect — and how to avoid delays that cost you money.

STATE BY STATE

Appeal Timelines by State

Every state has its own appeal process, deadlines, and escalation paths. The timeline you face depends on where your property is located and how far the appeal goes. For a full breakdown of the process, see our step-by-step appeal guide.

Michigan

Board of Review hearings in March. File with the Michigan Tax Tribunal by July 31. Most cases resolve in 6 to 18 months depending on complexity and whether the case settles or goes to hearing.

Ohio

File with the Board of Revision by March 31. Initial hearings typically take 3 to 6 months. Escalating to the Board of Tax Appeals (BTA) adds 1 to 2 years to the timeline.

Indiana

File with the PTABOA by June 15. Expect an initial hearing within 3 to 6 months. Escalating to the Indiana Board of Tax Review (IBTR) adds another 6 to 12 months.

Pennsylvania

File with the county Board of Assessment Appeals by your county's August or September deadline. Board decisions usually arrive within a few months; escalating to the Court of Common Pleas can add a year or more.

Wisconsin

Object at the Board of Review during its late-spring session, which often decides within weeks. Pursuing Department of Revenue review or circuit court certiorari can add several months to a year.

Georgia

File within 45 days of your assessment notice. The assessor review and Board of Equalization stage typically resolve within a few months; a Superior Court appeal extends the timeline further.

STAGE BY STAGE

What to Expect at Each Phase of the Appeal

While the details vary by state, every commercial property tax appeal follows the same general arc. Understanding each stage helps you plan ahead and avoid surprises.

Filing & Initial Review

Once you file your appeal, the reviewing body confirms receipt and schedules your case. This stage typically takes 2 to 8 weeks depending on the jurisdiction and filing volume.

Evidence Exchange & Negotiation

Both sides exchange evidence — comparable sales, income data, property condition details. Most commercial cases settle during this phase through direct negotiation with the assessor.

Hearing or Settlement

If the case doesn't settle, it proceeds to a formal hearing before a Board of Review, Board of Revision, or Tax Tribunal. Hearings are scheduled based on docket volume and can take several months.

Decision & Implementation

The board or tribunal issues a decision. If your assessment is reduced, the tax adjustment is applied and any overpayment is refunded or credited. This can take 2 to 4 additional weeks.

KEY FACTORS

What Determines How Long Your Appeal Takes

Not every appeal takes the same amount of time. Several factors influence whether your case resolves in months or stretches past a year. Understanding these helps you set realistic expectations. For more on what makes a strong case, see our evidence guide.

Jurisdiction and local board caseload

Strength and completeness of your evidence

Whether the assessor is willing to negotiate

Complexity of the property and valuation method

Whether the case escalates to a higher tribunal

Time of year you file relative to the deadline

WHY TIMING MATTERS

Start Early — Or Wait Another Year

Property tax appeal deadlines are strict. Miss one and you are locked into your current assessment for the entire year — there are no extensions and no exceptions. The earlier you start, the more time your team has to build a strong case and explore negotiation before the formal hearing process. Filing early also gives you first position on the docket, which often means a faster resolution. Need to know your exact deadline? See our state-by-state deadlines page or explore the appeal process for your state: Michigan, Indiana, Ohio, Pennsylvania, Wisconsin, or Georgia.

It depends on the state and whether the case settles or goes to a formal hearing. In Michigan, the process takes 6 to 18 months — see our 2026 Michigan property tax deadlines for the current-year filing calendar. In Ohio, expect 3 to 6 months at the Board of Revision level, longer if you escalate; the 2026 Ohio complaint deadlines guide covers the seasonal window. In Indiana, PTABOA hearings typically resolve within 3 to 6 months, but an IBTR appeal can add 6 to 12 months. In Pennsylvania, county Board of Assessment Appeals decisions usually land within a few months of the filing deadline, while a Court of Common Pleas appeal can add a year or more. In Wisconsin, the Board of Review often decides within weeks of its spring session, with Department of Revenue or circuit court review adding several months. In Georgia, the assessor review and Board of Equalization stage typically resolve within a few months, with a Superior Court appeal taking longer.

Yes. Filing early, submitting complete and well-organized evidence upfront, and engaging a professional who already has relationships with local assessors can all materially accelerate the process. Most commercial cases settle through negotiation well before a formal hearing, and early engagement gives you the best shot at being first in line on the docket. Procedural mistakes — wrong forms, missing signatures, incomplete schedules — are the single biggest source of unnecessary delay, and they are easy to avoid with experienced help. Our DIY vs professional comparison walks through the timing tradeoff in more detail. See our evidence guide and appeal process guide for what a clean, fast-moving filing looks like.

Missing the deadline means you cannot appeal for that tax year. You will pay the full assessed amount, and you'll have to wait until the next assessment cycle to try again — typically a full year. That's why deadline awareness is critical. See our filing deadlines guide for exact dates by state.

Yes — in virtually every jurisdiction we work in you are required to continue paying the current tax bill on its normal schedule while the appeal is pending. If the appeal succeeds, you typically receive a refund or credit for the overpayment once the revised assessment is certified, and in some counties that credit is applied automatically on the next installment. Falling behind on taxes during an appeal can actually put your case at risk and trigger penalties, so budgeting through the process matters. The deadlines guide lays out filing windows alongside the normal tax installment calendar so you can plan both.

Absolutely. A successful appeal reduces your assessment going forward, often for multiple years, and the savings compound annually whether the initial resolution takes three months or twelve. For a commercial property overpaying by $30,000 per year, a 12-month wait is a small price for ongoing relief — and a 30% reduction on a larger industrial or multifamily property can easily justify the wait several times over. Because most cases settle before a formal hearing, the actual time your team spends on the appeal is minimal compared to the savings. See our success rate guide for typical outcomes and the cost guide for how the economics actually play out.

Yes — if your initial filing doesn't resolve before the next assessment cycle begins, you may need to file a new appeal for the following year to preserve your rights. In Michigan, for example, Tax Tribunal cases frequently cover multiple tax years under a single docket, but you still need to be timely on each year's filing. In Ohio and Indiana, rolling protections depend on local rules and escalation paths. We track these overlapping windows for every engagement so nothing is left on the table while a prior year is still pending.
