The letter from the appraisal review board uses the word "denied," or it grants a reduction so small it barely moves the bill, and most homeowners read that as the end of the road. It almost never is. In nearly every state, a first-level denial is the middle of the process, not the end — there is a second venue waiting, and the assessor knows most people won't use it. The reason they don't is rarely that the case is weak. It's that the denial notice doesn't explain the next step, and the clock to take it is short: usually 30 to 60 days from the date of the decision, not from the day you opened the envelope.
This is a map of what comes after a denial — the three shapes a second-level appeal takes, what each one costs, the deadline in nine major states, and the only question that should decide whether you pursue it. That question is not whether the assessor was wrong. It's whether the math works.
Two details in the decision document control everything that follows, and both are easy to miss.
The first is the date. Your escalation clock starts from the date the board mailed or issued its determination (in New York, from the filing of the final assessment roll) — not from the day it reached you. A decision mailed while you were traveling can quietly burn a week or more of a 30-day window. Treat the date on the document, not the postmark on your memory, as the start of the count.
The second is what "denied" really means in your case. A board can deny outright, or it can grant a partial reduction. A partial reduction is still an adverse decision you can escalate — you are not obligated to accept a $4,000 cut when you documented a $20,000 overvaluation. But escalating restarts the evidentiary process at the next venue, so the question is whether the remaining gap is worth the next venue's cost. That is the calculation the rest of this guide is built around. If you haven't seen what a first-level proceeding looks like, our walk-through of what property tax appeal hearings actually look like covers the stage you've just finished; everything below is the stage after it.
Across all fifty states the second level takes one of three forms. Which one you get is set by your state and, sometimes, by your property type and value. Knowing the shape tells you the cost structure before you read a single statute.
A handful of states route denied appeals to a neutral arbitrator instead of a judge. Texas is the cleanest example and the one most homeowners encounter. After an Appraisal Review Board order, an owner can request Regular Binding Arbitration through the Texas Comptroller under Tax Code Chapter 41A. It is available for a residence homestead regardless of value, and for other property with an ARB-determined value of $5 million or less.
The economics are why it matters. The deposit runs on a sliding scale — $450 for a homestead valued up to $500,000, rising with value to $1,550 at the top of the range — and a $50 portion is a non-refundable administrative fee. The rest is refunded if the arbitrator's value lands closer to your opinion than to the ARB's. In practice that turns arbitration into a low-risk bet for a homeowner with solid comparable-sales evidence: you front a few hundred dollars, and you get most of it back if you're right. The deadline is 60 days from receiving the ARB order, and choosing arbitration is exclusive — filing a district-court suit instead waives your right to arbitrate the same property for that year.
The arbitration trap most people miss. Binding means binding. Unlike a board decision you can appeal, an arbitrator's award is the end of the line — there is no further appeal of the value. That's a feature when your evidence is strong (it forecloses the assessor's appeal too) and a risk when it's thin. Bring the same disciplined comp package you'd bring to court; the informality of arbitration does not lower the evidentiary bar, it just lowers the cost.
Several states send denied appeals to a dedicated statewide body that specializes in assessment disputes. The Illinois Property Tax Appeal Board (PTAB) is the model: after a county Board of Review decision, you file with PTAB within 30 days of the decision's postmark, and there is no filing fee. Illinois lets you choose PTAB or a tax-objection complaint in circuit court, but not both — PTAB is the lower-cost path and the one most residential owners use.
Ohio works the same way: a county Board of Revision decision can be appealed to the Ohio Board of Tax Appeals or the county Court of Common Pleas, within 30 days of the decision being mailed. New Jersey's second level is the New Jersey Tax Court — technically a court, but its small-claims track for residential property carries a $50 filing fee (versus $250 standard) and is built to be navigable, with a 45-day window from the county board's judgment.
The common thread: these venues are designed for taxpayers, the cost of entry is low, and a self-represented homeowner with good evidence is on reasonable footing. When your state offers a tribunal, it is almost always the right post-denial venue for a residential case.
The remaining states send you straight to court, with no specialized tribunal and no arbitration in between. This is the most expensive and most formal path, and it changes the break-even math sharply.
In Florida, a denial from the county Value Adjustment Board can only be challenged by filing suit in circuit court within 60 days — there is no statewide arbitration tier for assessment appeals. Pennsylvania routes appeals from the county Board of Assessment Appeals to the Court of Common Pleas within 30 days, with county filing fees commonly in the $200–$400 range. And California has a two-step quirk worth understanding: the county Assessment Appeals Board is the formal appeal level, so "post-denial" means filing a refund claim with the county board of supervisors within six months of the AAB decision, and only if that's denied does a Superior Court refund suit follow — where the unlimited-civil filing fee alone is $435 as of January 1, 2026.
Court is where representation starts to matter and where DIY gets harder. It is also where a strong, well-documented case can still win — but the cost floor is high enough that small disputes rarely justify it.
Nine states the Desk covers in depth, with the second-level venue, the deadline, the entry cost, and whether arbitration is on the table. Deadlines run from the board's decision unless noted.
| State | First-level body | Post-denial venue | Deadline | Entry cost | Arbitration? |
|---|---|---|---|---|---|
| Texas | Appraisal Review Board (ARB) | Binding arbitration (Comptroller), district court, or SOAH (>$1M) | 60 days | $450–$1,550 deposit, mostly refundable | Yes — homestead any value; other ≤$5M |
| Illinois | County Board of Review | PTAB or circuit court (choose one) | 30 days | PTAB free | No |
| Ohio | County Board of Revision | Ohio Board of Tax Appeals or Common Pleas | 30 days (from mailing) | Modest filing fee | No |
| New York | Board of Assessment Review (BAR) | SCAR (1–3 family) or Article 7 Supreme Court | 30 days (from final roll) | SCAR $30 | No |
| New Jersey | County Board of Taxation | NJ Tax Court | 45 days | $50 small claims / $250 standard | No |
| Georgia | Board of Equalization (BOE) | Superior Court | 30 days | $25 filing | Initial-stage only* |
| Pennsylvania | Board of Assessment Appeals | Court of Common Pleas | 30 days | ~$200–$400 (by county) | No |
| Florida | Value Adjustment Board (VAB) | Circuit Court | 60 days | Circuit court filing fees | No |
| California | Assessment Appeals Board (AAB) | Refund claim → Superior Court suit | 6 months (refund claim) | $435 Superior Court (unlimited civil) | No |
*Georgia's arbitration is not a post-denial option. Georgia does offer binding arbitration — but you must elect it at the start of the appeal, in place of the Board of Equalization, not after a BOE denial. And a Georgia arbitration award is final: it cannot be appealed to superior court, while a BOE decision can. So in Georgia the genuine post-denial route is superior court within 30 days. The arbitration choice is one you make before the first hearing, not after it.
Whether to escalate is not a referendum on how wrong the assessor was. It's a comparison of two numbers: the cost of the next venue against the reduction you realistically expect, multiplied by the number of years it will hold.
That second factor is the one people forget. A reduction isn't a one-year prize in every state. As our analysis of the year-two problem lays out, some states lock an appeal win in place for two or three years through statutory carryforward, while others reset the value annually — so the same $300 annual reduction is worth $900 in a carryforward state and $300 (or a yearly refiling) in a reset state. Run the durable number, not the first-year number.
Against that, weigh the venue's true cost — not just the filing fee, but your time and (for court) likely representation. The pattern that falls out is consistent:
This is also where the contingency-fee firms stop being useful. A service company working on a percentage of first-year savings has little incentive to chase a multi-year court case for you, and its savings math is built around the first-year number that understates a carryforward win. The post-denial decision is exactly the kind of judgment a firm won't make in your interest — which is why it's worth running yourself, or with a flat-fee attorney whose incentives line up with the durable outcome. Our DIY-vs-hire decision matrix frames that choice in detail.
